Abstract

The United Nations Law of the Sea Convention (LOSC) 1982 indicates that a coastal State may make a claim to continental shelf extending beyond 200 nautical miles (Extended Continental Shelf, ECS). In order for a coastal State to exercise its sovereign rights over the ECS, a submission containing the outer limit of its continental shelf should be deposited to the Commission on the Limits of the Continental Shelf (CLCS) trough the Secretary-General of the United Nations.
Indonesia is one of the coastal States, which may potentially make such a claim to continental shelf beyond 200 nautical miles from its baselines. Preliminary studies also suggest that Indonesia may be able to advance such claims in several locations. At the time of writing, Indonesia is currently preparing for its ECS submission, with a deadline of 13 May 2009. The present paper is aimed at outlining the development of Indonesia's ECS claim, including analysis of the current status of the submission preparations as well as the challenges that Indonesia is facing. While giving particular emphasis to technical aspects, this paper will, necessarily, discuss legal issues associated with Indonesia's ECS submission.
This paper generally covers the principles related to the definition of the outer limits of the ECS, with an emphasis on the formulae and constraints as set out in Article 76 of LOSC, technical aspects of ECS definition, and the latest status and problems related to Indonesia's ECS submission. Wherever possible, this discussion is also intended to provide possible options to overcome the identified problems.

Keywords: extended continental shelf, LOSC, article 76, CLSC, submission, formulae, constraint

Remark: accepted for oral presentation at MapAsia 2007 in Kuala Lumpur.

Settling Maritime Boudaries

I Made Andi Arsana, Asian Surveying and Mapping, 13 June 2007

East Timor, the youngest country in the world, celebrated the fifth anniversary of its independence from Indonesia on 20 May. It is a country of tremendous challenges -- it is one of the poorest in the world -- but it is also one with great hopes for the future.

In recent elections, the Timorese voted Nobel Peace Prize winner Jose Ramos-Horta as the country's new president. Among his most urgent tasks: fighting poverty. In particular, he needs to ensure access to the revenues that will flow from the oil-rich seabed of the Timor Sea. More...

Landas Kontinen Ekstensi - Dua Masalah [?]

Dalam pencarian saya yang tentunya masih belum seberapa, saya menemukan beberapa pendapat yang berbeda tentang dua hal mengenai landas kontinen.

Pertama adalah mengenai kriteria batas terluar, terutama menyangkut constraints. Beberapa tulisan menyatakan dengan tegas bahwa batas terluar adalah tidak melebihi 350 mil laut dari garis pangkal.

Menurut pencarian saya, pandangan ini tidak sesuai dengan apa yang disebutkan dalam pasal 76 UNCLOS yang mengemukakan ada dua constraints yaitu 350 mil laut dari garis pangkal dan 2500 m isobat + 100 mil laut ke arah laut lepas. Yang terpenting dari kedua constraints ini adalah adanya operator logika ATAU (OR) yang menghubungkan keduanya, bukan DAN (AND). Artinya, bisa dipilih salah satu dan yang the "most advantageous". Artinya, mana dari kedua constraints itu yang menghasilkan batas paling luar/jauh, maka constraint itulah yang digunakan. Dengan kata lain, bisa saja batas terluar LK lebih dari 350 mil laut sepanjangan constraint 2500 m isobat + 100 mil laut masih terpenuhi. Untuk ini saya coba buatkan animasinya agar lebih mudah mengilustrasikan, silahkan dicermati dan dikomentari.

Hal kedua adalah perihal deadline pengajuan submisi ke CLCS.
Saya melihat masih ada pendapat yang menganggap deadline untuk submisi adalah 16 November 2009. Saya duga pendapat ini dilandasi oleh suatu anggapan bahwa semula deadline submisi adalah 10 tahun sejak berlakunya UNCLOS (16 November 1994) sehingga deadline adalah 16 Nov 2004 dan kemudian "diundur" selama 5 tahun sehingga menjadi 16 November 2009. Menurut penelusuran saya, deadline submisi tidak dihitung dengan prinsip seperti itu, melainkan dengan pertimbangan saat diadopsinya/disetujuinya petunjuk ilmiah dan teknis batas terluar landas kontinen oleh CLCS.

Pada Meeting of State Parties of UNCLOS tahun 2001, disepakati bahwa submisi dari negara pantai disepakati 10 tahun sejak diadopsinya petunjuk ilmiah dan teknis batas terluar landas kontinen oleh CLCS yang dalam hal ini adalah 13 Mei 1999. Artinya, 10 tahun sejak tanggal ini adalah 12 Mei 2009 (lihat juga SPLOS/72). Hal ini tentu saja berlaku untuk negara pantai yang sudah meratifikasi UNCLOS sebelum 13 Mei 1999, termasuk Indonesia.

Perihal deadline ini menjadi penting untuk dicatat karena kesalahan pemahaman akan deadline bisa berakibat fatal bagi Indonesia yang akan melakukan submisi, terlebih dengan cara parsial.

Pendapat saya ini dalam rangka mengomentari beberapa makalah termasuk yang ditulis oleh pakar-pakar Indonesia mengenai landas kontinen. Ada pendapat lain?

Timor Leste must settle maritime boundary

Opinion and Editorial in The Jakarta Post - May 23, 2007

I Made Andi Arsana, Wollongong, Australia

Timor Leste's recent successful election has given the country a new president, Jose Ramos-Horta. Voters have a lot riding on the Nobel Peace Prize winner's ability to overcome the myriad challenges facing the young country. One of those challenges, and one that Timor Leste must prioritize now, is the settlement of the country's maritime boundaries.

East Timor: Beyond Independence

This book is edited by D. Kingsbury and M. Leach of Deakin University. Clive and I contribute one chapter in this book concerning East Timorese maritime boundary delimitation. The chapter contributed is “The Delimitation of Maritime Boundaries: A Matter of ‘Life or Death” for East Timor?”. It is originally the paper I presented in the Indonesian Council Open Conference in Flinders University, Adelaide in September 2005. I Met Damien, the editor, as we both presented papers at the event. Damien, through his email, asked me to contribute the paper as a chapter in the book. A very interesting offer. I am so happy, the book has now been published.

This is taken from the website of Monash Asia Institute Press:

This is the most comprehensive study of East Timor since independence, examining the major themes of development, borders and security, politics and justice, resource and land management, education, and language policy. Though the country was initially lauded as a case study in successful state-building, the crisis of 2006 demonstrated that East Timor had more in common with other post-colonial, post-conflict societies than some of these earlier optimistic assessments.

East Timor continues to attract the interest and attention of governments, scholars, development institutions and aid workers as a society rebuilding itself after almost a quarter of a century of profound trauma, and consecutive eras of colonialism.

Covering the era from the independence referendum in August 1999 to the political crisis in 2006, and future prospects and challenges, this book is an invaluable resource for understanding the challenges facing the first new nation of the 21st centur

My New Book: Ask Google Guru

Dear Colleagues,

This is a promotion of my new book that will be available in market on 10 May 2007 (Elex Media Komputindo). This time, the topic is quite light. It is not geodesy, nor law of the sea, neither maritime boundary disputes (but not a novel, either) ha ha..
The topic is something you are familiar with: Google.

Have you ever wondered?

1. How to find a tsunami animation using Google?
2. How to find Power point (ppt) files for teaching materials (lecturers will love this)?
3. How to search PDF files only from the Indonesian university websites?
4. I do not know what "mutatis mutandis" means. Can Google define it for me?
5. How many meters is one nautical mile? Can Google help me?
6. I need to have daily update regarding my research topic sent to my email. Can Google do something?
7. What is the speed of light?
8. If there are two objects, 12 and 10 kg each and separated by 15 meters, How strong is the force between them?
9. How much is one dollar in rupiah, today?
10. Can Google help me search files in my PC?

If you answer "yes" to one of the above questions, then my book might be helpful to you. Sorry, I cant stop myself from mentioning this advertisement part :). Thank you very much for your attention and happy reading (after buying one)

Segera Terbit: Buku "Batas Maritim Antarnegara"

Perjuangan untuk menulis buku ini, seperti diduga, ternyata tidaklah mudah. Kenyataannya bahkan, dalam beberapa hal, lebih sulit dari kesulitan yang dibayangkan sebelumnya. Yang pasti, lebih lama dari yang dibayangkan. Penulisan buku ini sebenarnya bercikal bakal thesis master di UNSW dan berniat diselesaikan tahun 2006. Ternyata kenyataan bercerita lain. Tidak mudah mewujudkan gagasan menjadi kalimat yang tertata baik dan terutama yang mudah dipahami orang awam. Seperti itulah seharusnya sebuah buku. Apapun itu, perjuangan itu kini telah sampai pada titik yang tidak terlalu mengecewakan. Gama Press telah menyatakan kesanggupannya untuk menerbitkan, setelah "lolos" dari cengkraman reviewer beberapa lama.

Tidak jelas kapan buku ini bisa dinikmati di pasar, yang jelas sangat layak untuk dinantikan. Silahkan simak daftar isinya di sini.

Pelanggaran hak cipta di Kaltim Post

Tidak sengaja saya menemukan kejanggalan di Kaltim Post. Ada tulisan saya dimuat perihal batas desa tetapi TIDAK mencantumkan nama saya sebagai penulis. Tulisan ini memang saya kirim kepada redaksi opini Kaltimpost beberapa waktu lalu dengan harapan bisa dimuat. Harapan saya memang terpenuhi, tetapi ternyata identitas saya dikorupsi.

Saat berita ini saya buat, saya sudah mengirimkan email kepada Kaltimpost. Isinya seperti ini:

Dear Redaksi Kaltimpost
(Attn. Bapak Ridwan Alkaf)

Hari ini saya menemukan kejanggalan di Kaltim Post.
Saya membaca tulisan yang saya kirim ke Kaltim Post beberapa waktu lalu dan dimuat tanggal 16 April 2007.

Saya yakin tulisan tersebut adalah sepenuhnya karya saya, tetapi pada pemuatannya tidak mencantumkan nama saya sebagai penulis.

Tulisan yang saya maksud adalah:
http://www.kaltimpost.web.id/berita/index.asp?IDKategori=Opini&id=207116

Saya yakin, ini adalah rubrik opini yang seharusnya mencantumkan nama penulisnya, seperti juga opini lain di koran tersebut. Saya amati selalu ada nama penulis di bagian bawah tulisan. Saya mohon penjelasan mengapa hal ini terjadi? Apakah 'kesalahan' ini hanya terjadi pada edisi online? Bagaimana dengan edisi cetak? Jika pada edisi cetak tidak terjadi kesalahan, saya mohon diberikan buktinya pada saya.

Jika ini adalah kesalahan entah sengaja atau tidak, saya menganggapnya sebagai sesuatu yang serius. Kaltim post harus merespon in secara proporsional. Jika ternyata saya salah mengamati, mohon informasinya.

Sekedar informasi, saya menulis di banyak harian nasional dan internasional, termasuk menulis buku dan jurnal. Saya sangat memperhatikan hal-hal seperti ini. Saya benar-benar membutuhkan tanggapan segera dari Kaltim Post.

Demikian penyampaian saya, semoga berkenan dan direspon sesegera mungkin.

It has been a month

Today, I have been in this fellowship program for a month. Not much progress has been achieved, really. However, I have managed to complete the report outline so I know where to head and what to write. One more thing, at least I am fully settled now in Wollongong. A bike has also been provided (lend) by Clive. What a supervisor :) I remember when I was doing my master, Clive also gave me some kitchen utensils. Now he lend me a bike. I wonder what I can expect for my PhD ha ha ha.

Back to serious matter.
I have started writing my report today. At least, I finally wrote some sentences in the "Introduction" section. Not yet much, but I have begun. Everybody knows, starting is the most difficult part. Does it mean that I have done the most difficult part of my research?

I will keep you posted!

Research starts

Well, Let's now start talking about something serious: My research. Serious? isn't everything in this blog serious? Aha.. you might be right. This blog, when it was created, was aimed at accommodating serious matters. You might want to read my first posting, almost three years ago :)

Anyway, the research we are talking about now is not the one I did three years ago for about two years. The current research is the one under the UN-Nippon fellowship. This takes me back to Australia and am now in The Australian National Centre for Ocean Resources and Security (ANCORS), which was formerly known as Centre for Maritime Policy (CMP). The centre belongs to University of Wollongong, Australia and I am working with (again) Clive as my Supervisor :)

My research is about The submission of Indonesian Extended Continental Shelf. I am looking at its status and problems. A report outline has been discussed with Clive and has also been commented by people from the UN. I am now currently revising the outline before starting to write the report.

Next postings here will be closely related to what I am currently researching. Hope you enjoy them.

Indonesia-Singapore talks on maritime borders making progress

Klick here for English
Yang mengikuti perkembangan perundingan batas maritim antara Indonesia dan Singapura mungkin sudah tahu kalau Singapura menyatakan tidak akan menggunakan garis pantai hasil reklamasi untuk menentukan batasnya dengan Indonesia.

Jika ini benar maka Indonesia mungkin bisa sedikit berlega hati. Persoalan selanjutnya adalah bagaimana delimitasi dilakukan secara teknis dan terjamin bahwa garis pantai yang digunakan adalah yang "asli" sebelum reklamasi. Ini terkait aspek teknis termasuk penggunaan peta laut dll.

Aspek lain adalah perlunya penetapan datum geodesi untuk batas maritim selanjutnya agar tidak seperti batas maritim yang sekarang, tanpa datum geodesi.

Animate the Law

Being in a place where no surveyor other than me is, to an extent, very glorious. I could feel that I am useful and am the man with the most precious knowledge ha ha. Surrounded by lawyers who are keen to know more about technical aspects of the law of the sea gave me privileges to express my technical and spatial expertise.

Honestly, I did not realize what I know is significantly important and is precious to my lawyer colleagues. I am talking about the ability of technical people (read: surveyors) to explain legal problem using graphs, charts, and even animations. A very good example of this situation is when lawyers try to understand the meaning of Article 76 of the UNCLOS. It is not very easy to understand the very long article without sufficient knowledge of technical aspects.

I am quite lucky with my “weird” creativity to stay for hours (or even days) in front of computer “converting” those complicated legal expression in article 76 into a nice, simple and easy-to-understand animation. I found that even the lawyers find it a lot easier to understand the article by seeing my animation with minimum oral explanation. Want to see the amusement? :) Please contact me!

Early last year, the Home Ministry regulation on regional boundaries came into force. The regulation provides systematic guidelines for regional boundary demarcations over land and sea.

For the newly elected local leaders in Indonesia -- governors and regents -- the regulation should be viewed as important, since settling regional boundaries is now becoming urgent. The implementation of regional autonomy requires local leaders to optimally manage and exploit the resources in their areas. Continue...

I Made Andi Arsana and Ni Made Kesuma Putri , Yogyakarta

United Nations Convention on the Law of the Sea, UNCLOS, where Indonesia is a party to, indicates that a coastal State may extend its continental shelf claim beyond 200 nautical miles (nm). As defined by UNCLOS, continental shelf is “the seabed and subsoil of the submarine areas that extend beyond its territorial sea throughout the natural prolongation of its land territory to the outer edge of the continental margin”. To those with outer edge of continental margin less then 200 nm, they are entitled to 200 nm of continental shelf as long as there is no dispute with third parties. Meanwhile, a coastal state wishing to claim continental shelf beyond 200 nm (hereinafter referred to as extended continental shelf, ECS) has to submit its claim to the Commission on the Limits of the continental shelf (CLCS) through the UN Secretary-General.

As stated in Article 76 of UNCLOS, there are four important points to consider in determining the outer limit of the ECS. The first two points govern technical criteria on how to delimit the outer limit of ECS. These include the criteria of sedimentary rock thickness and the distance from the foot of continental slope. Meanwhile, the last two points relate to constraints in determining the outer limit of the ECS. They state that the outer limit of the ECS must not exceed 350 nm from baseline (usually coastline) or “shall not exceed 100 nautical miles from the 2,500 meter isobath, which is a line connecting the depth of 2,500 meters.” Detail explanation of these technical procedures can be read in Article 76 of UNCLOS, which is also available online at the United Nations’ website.

Meeting of the State Parties in 2001 indicated that 14 countries meet the technical criteria to claim ECS, including Indonesia. The deadline for submission has also been extended from 16 November 2004 to 12 May 2009. To some countries, including Indonesia, this is very good news as there will be more time to prepare for the submission. On the other hand, six coastal States (parties) have submitted their claims and their documents are accessible through the website of CLCS (http://www.un.org/Depts/los/clcs_new/clcs_home.htm). Those six parties include Russia, Brazil, Australia, Ireland, New Zealand and Joint submission by France, Ireland, Spain and the United Kingdom of Great Britain and Northern Ireland. Any country can access the documents as well as respond to their claim. All responses will then be made available in the website for public access. Indonesia, once again, has not provided any response to other States’ ECS claim, not even to Australia’s as one of the nearest neighbors. Meanwhile, other countries including East Timor are very responsive to provide comments, especially to those related to their national interest. It is to us unclear, why Indonesia has not done so. There must be reasons for that.

With regard to the potency of Indonesian ECS claim, a global study of the United States Geological Survey (USGS) shows that Indonesia may possibly claim ECS for the maritime area to the west of Sumatra Island and to the south of Sumba Island. This, however, is a global study and can only be used as an initial reference. More comprehensive studies have to be carried out to find a more precise result of potency. Similarly, a study conducted by Indonesian Experts (Sutisna, et al., 2005) also highlighted the potency of Indonesian ECS claim for the maritime area to the west of Sumatra, to the south of Sumba and to the north of Papua. However, as indicated in their paper, their study needs further investigation for a more comprehensive result.

Submitting ECS claim, as indicated by CLCS, is by no mean an easy task. It requires comprehensive studies and reasonably complicated procedures for the submission to be accepted. UNCLOS says that “coastal State shall deposit with the Secretary-General of the United Nations charts and relevant information, including geodetic data, permanently describing the outer limits of its continental shelf.” This confirms that preparing ECS submission will involve hydrographic survey for data acquisition, geospatial data processing, and legal argument preparation to support technical aspects. As far as we are concerned, Indonesian government through its relevant institutions is currently conducted serious preparation including hydrographic survey for the area with ECS potency. Significant progress should have been achieved, we are sure.

With regard to its prospect, some opine that submitting ECS claim is not worth it. To them, cost it requires for preparation including field survey and document preparation is too high compared to benefit Indonesia may gain. It is wiser to spend that money for other sectors which are more important, such as health care and education. This opinion is, undoubtedly, worth considering. It is true that Indonesian government should not carelessly spend that much money for something with no good prospect. However, ECS claim is not a matter of today. It is not something that we can judge instantly whether it is beneficial or not. ECS claim is a future investment. It is not only a matter of economy and how large ocean resources can be exploited from the continental shelf but also legal existence and sovereign rights of Indonesia. ECS claim also to anticipate dispute that may occur due to ECS claim by other neighboring States.

Regardless of pros and cons, we hope Indonesian government has been thinking of this matter seriously. Let us see how we are going to extend our maritime claims.

Arti Penting Penegasan Batas Wilayah Antar Daerah

I Made Andi Arsana, ST, ME¹

Isu batas wilayah Jogja-Jateng belakangan ini marak dibicarakan. Sebuah berita mengatakan bahwa perubahan batas DIY-Jateng yang terjadi pada 213 titik menyebabkan menyempitnya wilayah Jogja.

Persoalan batas memang multi-dimensi yang melibatkan aspek legal, teknis, dan sosial ekonomi. Sengketa batas wilayah bisa menimbulkan berbagai persoalan yang terkait setidaknya dengan ketiga aspek tersebut. Tulisan ini tidak akan secara spesifik mengulas permasalahan batas antara DIY-Jateng, melainkan memberikan gambaran yang lebih umum sifatnya dan semoga bisa menjadi pengetahuan bagi siapa saja yang tertarik dan berkepentingan dengan perihal batas daerah.

Diberlakukannya Undang-undang No. 22/1999 tentang Pemerintahan Daerah merupakan titik awal dilaksanakannya konsep otonomi daerah di Indonesia. Kini UU ini direvisi menjadi UU No. 32/2004 yang salah satunya mengatur penentuan dan penegasan batas wilayah baik di darat maupun di laut. Untuk mendukung ini, Menteri Dalam Negeri telah mengeluarkan Peraturan No. 1 tahun 2006 (selanjutnya disebut Permendagri) tentang Pedoman Penegasan Batas Daerah.

Perlu diperhatikan bahwa istilah ”penentuan” dan ”penegasan” memiliki pengertian yang berbeda. Penentuan mengacu kepada penetapan batas di atas peta, sedangkan penegasan adalah penetapan titik-titik batas di lapangan. Dengan kata lain, penegasan adalah tindak lanjut dari penentuan batas. Hal ini ditegaskan dalam Permendagri yang menyebutkan bahwa “penegasan batas daerah dititikberatkan pada upaya mewujudkan batas daerah yang jelas dan pasti baik aspek yuridis maupun fisik di lapangan” (Pasal 2 ayat 1).

Penegasan batas darat meliputi beberapa langkah yaitu penelitian dokumen, pelacakan batas, pemasangan pilar batas, pengukuran dan penentuan posisi pilar batas, dan pembuatan peta batas. Dalam penegasan batas ini, seperti yang secara eksplisit disebutkan dalam Permendagri pasal 4 ayat 2, wajib diterapkan prinsip geodesi. Jelas terlihat dalam hal ini bahwa peran surveyor geodesi sangat penting dalam penegasan batas daerah.

Terkait kewenangan daerah di wilayah laut, alasan perlunya batas laut adalah untuk menyelesaikan tumpang tindih klaim (overlapping claim) daerah di wilayah laut. Seperti dijelaskan dalam UU No.32/2004, sebuah provinsi yang memiliki laut berhak atas kewenangan laut sejauh 12 mil laut dari garis dasar (biasanya garis pantai). Tentu bisa dipahami bahwa akan terjadi tumpang-tindih klaim jika ada dua provinsi berseberangan (opposite) yang berjarak kurang dari 24 mil laut atau dua provinsi yang berdampingan (adjecent) dalam satu wilayah daratan pulau seperti Jogja dan Jateng. Untuk menghindari sengketa, maka perlu ditarik garis batas yang disepakati oleh semua pihak yang berkepentingan.

Permendagri juga menegaskan bawah ada 6 langkah utama yang harus dilakukan dalam penentuan batas wilayah laut yaitu penelitian dokumen, pelacakan batas, pemasangan pilar dan titik acuan, penentuan titik awal dan garis dasar, pengukuran dan penentuan batas, dan pebuatan peta batas. Berbeda dengan batas darat, pemasangan pilar tidak dilakukan di titik batas, yang notabene di tengah laut, tetapi di darat (pantai) yang dijadikan referensi dalam menentukan posisi titik batas maritim antar provinsi.

Secara teknis, aspek yang sangat penting dalam penegasan batas daerah adalah prinsip geodesi atau survei pemetaan. Hal yang harus diperhatikan dalam penentuan dan penegasan batas adalah jenis batas yang akan digunakan, teknologi yang dipilih terkait kualitas hasil yang diharapkan, serta partisipasi masyarakat yang secara langsung akan tekena dampak akibat adanya penegasan batas tersebut.

Untuk darat, misalnya, batas bisa ditentukan dengan unsur alam (sungai, watershed, dan danau), dan unsur buatan (jalan, rel kereta, saluran irigasi, dan pilar batas). Penggunaan unsur-unsur alam akan mengakibatkan batas menjadi dinamis akibat perubahan bentang alam. Hal inilah yang mengakibatkan bergesernya batas antara DIY dan Jateng. Namun demikian, penggunaan unsur alam ini umumnya mudah diidentifikasi oleh masyarakat sekitar.

Untuk batas dari unsur buatan seperti pilar batas, penentuan posisi yang akurat merupakan hal penting. Dalam kaidah geodesi, penentuan posisi pilar batas harus dinyatakan dalam koordinat dengan datum dan sistem proyeksi yang jelas. Angka koordinat tanpa spesifikasi datum yang pasti sesungguhnya tidak menjelaskan apa-apa. Koordinat yang sama jika datumnya berbeda akan mengacu pada posisi yang berbeda di lapangan. Sebaliknya, suatu posisi tertentu di lapangan bisa dinyatakan dengan koordinat yang berbeda jika datum dan sistem proyeksinya berbeda.
Terkait dengan ketelitian posisi/koordinat titik batas, Permendagri juga sudah memberikan spesifikasi yang rinci. Ketelitian ini tentunya terkait dengan teknologi dan metode penentuan posisi yang digunakan. Penentuan posisi dengan Global Positioning System (GPS), yaitu penentuan posisi dengan satelit, adalah salah satu yang direkomendasikan. Namun demikian, penggunaan GPS sendiri harus memperhatikan jenis dan metode pengukurannya untuk mendapatkan posisi dengan ketelitian yang disyaratkan. Pengukuran dengan GPS navigasi (handheld) seperti yang sekarang populer di masyarakat berupa peranti seukuran handphone tentu saja menghasilkan ketelitian posisi yang lebih rendah dibandingkan penggunaan GPS jenis geodetik yang dilakukan secara relatif (deferensial). Tim Penegasan Batas di tingkat provinsi maupun pusat harus memahami hal ini.
Dalam era otonomi di mana luas daerah menjadi salah satu indikator dalam perhitungan Dana Alokasi Umum (DAU), batas daerah menjadi sangat penting artinya. Tanpa batas yang tegas, luas tidak mungkin dihitung. Oleh karena itu, penentuan dan penegasan batas merupakan agenda penting dalam melaksanakan otonomi daerah.
Terkait DAU, ada sebuah wacana bahwa luas wilayah yang berpengaruh terhadap besarnya DAU yang diterima suatu daerah seharusnya bukan saja luas daratan seperti yang berlaku sekarang, tetapi juga luas laut. Hal ini untuk menciptakan keadilan bagi daerah yang berbentuk kepulauan di mana luas daratannya lebih sempit dari luas wilayah laut yang menghubungkan pulau-pulau dalam provinsi tersebut. Meskipun masih wacana, hal ini telah menjadi kajian serius berbagai pihak, dan ini juga mengindikasikan bahwa penentuan (delimitasi) batas maritim antar daerah menjadi penting.
Lepas dari perhitungan DAU, menentuan batas maritim tetap harus mengacu kepada prinsip Negara Kesatuan Republik Indonesia, bukan untuk memecah belah daerah. Bisa dikatakan bahwa penentuan batas maritim ini adalah dalam rangka menghitung luas saja, bukan dalam rangka memberikan kewenangan penuh kepada daerah untuk menguasai laut.
Memang membicarakan batas tidak cukup dalam satu artikel. Sangat banyak aspek yang harus diperhitungkan. Satu hal yang penting dan menjadi PR pemerintah daerah adalah bawah penentuan dan penegasan batas merupakan agenda yang harus dijadikan prioritas. Perangkat hukum untuk inipun telah dipersiapkan. Jika sumberdaya adalah persoalannya, maka kerjasama bisa dilakukan dengan pihak terkait seperti lembaga kajian/pendidikan, pihak swasta dan pemerintah pusat. Mari kita mulai!

INSIDEN PENEMBAKAN NELAYAN DAN BATAS MARITIM

Muhammad Iqbal Taftazani *)

Beberapa waktu yang lalu terjadi sebuah peristiwa yang cukup mengejutkan kita semua, yaitu adanya insiden penembakan nelayan Indonesia oleh Tentara Laut Diraja Malaysia (TLDM). Insiden tersebut terjadi di sekitar Pulau Berhala di selat Malaka. Insiden itu sendiri terjadi setelah nelayan Indonesia dianggap telah memasuki wilayah perairan Malaysia.

Terlepas dari efek insiden penembakan tersebut bagi kedua Negara (Malaysia dan Indonesia), ada hal menarik yang kemudian perlu kita pahami bersama terkait dengan batas wilayah terutama batas maritim antar negara. Pernyataan tentang nelayan Indonesia yang memasuki perairan Malaysia tentu tidak bisa dileaskan dari pemahaman terhadap batas maritim antara Indonesia dan Malaysia di Selata Malaka.

Seperti kita ketahui bahwa Negara Indonesia terletak di antara dua samudera dan dua benua yang bertetangga dengan beberapa negara. Mengingat jaraknya yang relatif dekat, Indonesia berkepentingan untuk menetapkan batas maritim dengan 10 negara tetangga yaitu India, Thailand, Malaysia, Singapura, Vietnam, Filipina, Palau, Papua Nu Gini, Australia, dan Timor Timur. Hal ini dalam rangka mempertegas kedaulatan dan hak berdaulat Indonesia atas wilayah maritim di sekitarnya.

Ada sejarah panjang yang terangkai mengenai batas wilayah Negara antara Indonesia dan Malaysia, baik batas darat maupun batas maritim. Yang menarik untuk dibahas pada topik ini adalah mengenai batas maritim antara Indonesia dan Malaysia. Pada tahun 1969 sudah ada perjanjian antara Indonesia dan Malaysia mengenai batas landas kontinen (dasar laut) antara kedua Negara. Perjanjian tersebut juga mencakup perbatasan di pulau Natuna dan semenanjung Malaysia di sebelah barat Laut Cina Selatan. Dan pada tahun 1970 ada tambahan perjanjian batas antara Malaysia dan Indonesia mengenai perbatasan Laut Wilayah (territorial sea).

Laut wilayah adalah kawasan perairan suatu Negara yang diukur sejauh 12 mil laut dari garis pangkal suatu Negara (biasanya berupa garis pantai). Jika ada dua Negara yang berdekatan sama-sama mengklaim 12 mil laut untuk laut wilayah dan bertampalan (overlap) maka perlu ditegaskan batas antar perairan laut wilayah tersebut. Batas antar laut wilayah tersebut mencakup tubuh air (water column). Batas inilah yang kemudian digunakan sebagai penanda adanya pelanggaran di wilayah perairan seperti apa yang dituduhkan kepada nelayan Indonesia. Tanpa adaya batas laut yang memisahkan tubuh air, sesungguhnya tidak ada dasar untuk mengatakan sebuah kapal telah memasuki wilayah perairan negara lain mengingat aktivitas kapal nelayan ini adalah di air, bukan di dasar laut, bukan di udara. Mari kita lihat kondisi batas laut antara Indonesia dan Malaysia di Selat Malaka.

Batas wilayah antara Indonesia dan Malaysia ditarik dari dekat Singapura dan berakhir di dekat Pula Batu Mandi di Selat Malaka. Artinya tidak ada batas perairan yang berupa batas laut wilayah antara Malaysia dan Indonesia setelah Pulau Batu Mandi ke arah Barat Laut di Selat Malaka. Yang ada hanyalah batas landas kontinen yang ditetapkan pada tahun 1969. Batas landas kontinen, sesuai dengan hukum laut internasional, merupakan batas yang memisahkan dasar laut dua atau lebih negara. Batas landas kontinen tersebut tidak mengatur batas tubuh air. Sehingga secara umum, batas landas kontinen ini berlaku dalam hal pengelolaan lapisan di bawah laut (dasar laut) yang biasanya digunakan untuk pertambangan lepas pantai (off shore).

Menilik kembali insiden yang terjadi, lokasi insiden penembakan tersebut terjadi di sekitar Pulau Berhala. Sayangnya, tidak diketahui secara pasti lokasinya (yang dinyatakan dengan koordinat lokasi insiden). Secara geografis, letak pulau Berhala berada di sebelah utara Pulau Batu Mandi. Artinya lokasi insiden berada di sebelah utara titik paling utara batas laut wilayah Indonesia dan Malaysia. Jika hal tersebut benar (mengenai lokasi insiden) maka di wilayah tersebut tidak ada batas tubuh air. Yang ada hanyalah batas landas kontinen yang membatasi dasar lautnya saja dan tidak membatasi tubuh air.

Artinya apa? Bahwa insiden tersebut terjadi di daerah yang belum jelas batas tubuh airnya. Dengan kata lain, tidak ada dasar hukum yang dijadikan pegangan untuk mengatakan Nelayan Indonesia telah memasuki wilayah perairan Malaysia. Namun begitu, seperti yang diberitakan di media massa, tuduhan atas pelanggaran batas tidak hanya dilakukan oleh Malaysia, tetapi juga Indonesia. Tangkap-menangkap nelayan memang sesuatu yang cukup lumrah di Selat Malaka. Hal ini mengisyaratkan adanya suatu penerimaan secara defakto bahwa batas dasar laut di Selat Malaka juga dianggap batas tubuh air.

Insiden penembakan nelayan tersebut, idealnya, bisa dicegah oleh kedua negara dengan menetapkan batas antara perairan Indonesia dan Malaysia, terutama yang membatasi tubuh air. Dalam hal ini perlu ditetapkan batas maritim untuk Zona Ekonomi Eksklusif (ZEE) di Selat Malaka. Dengan adanya batas tersebut, dan didukung oleh sosialisasi batas maritim yang baik dari kedua pemerintah bertetangga, para nelayan idealnya akan mengetau apakah posisinya sudah melewati batas atau belum. Selain itu, adanya batas perairan akan semakin mengefektifkan patroli keamanan perbatasan yang dilakukan kedua Negara. Masing-masing petugas patroli tidak akan ada prasangka yang berlebihan dalam hal yang berkaitan dengan apakah suatu pihak sudah melewati perbatasan (perairan) atau belum.

Dengan adanya hal tersebut, diharapkan dapat meningkatkan jalinan persahabatan kedua Negara, terlebih lagi kedua Negara berasal dari rumpun yang sama, yaitu Melayu.
Wallahu a’lam…

A BIG Project: TALOS Translation

Manual on the Technical Apects of the UNCLOS (TALOS) sudah diperbaharui tahun 2006 ini. Setelah selama 13 tahun bertahan dengan edisi pertama, akhirnya TALOS diperbaharui tahun ini.

Sebagai negara kepulauan yang banyak berurusan dengan hukum laut dan batas maritim. Sangat sedikit orang Indonesia yang tertarik mendalami hukum laut. Jika ada, maka sebagian besar bergelut dengan aspek hukup dan politis, tanpa menyentuh perihal teknis. TALOS sesunggguhnya bisa menjadi sumber yang sangat bagus bagi yang ingin mendalami aspek teknis UNCLOS.

Pemahaman terhadap TALOS adalah mutlak untuk menghasilkan solusi implementasi UNCLOS secara komprehensif, terutama dari aspek teknis. Meskipun dokumen ini diterbitkan dalam beberapa bahasa, secara formal tidak ada terbitan dalam Bahasa Indonesia. Hal ini tentunya mempersempit lingkup pembaca TALOS di Indonesia, terutama mereka yang tidak tertarik untuk membaca dalam bahasa selain Bahasa Indonesia. Hal inilah yang menjadi motivasi perlunya dilakukan penerjemahan TALOS ke dalam Bahasa Indonesia.

Penerjemahan TALOS ini adalah sebuah proyek idealis yang akhirnya disambut baik oleh Dr. Sobar Sutisna, Bakosurtanal.

Proyek ini utamanya dimotori oleh Pusat Kajian Kewilayahan dan Perbatasan FT UGM-Bakosurtanal (atau dikenal juga dengan nama Pusat Studi Batas Wilayah) dengan melibatkan mahasiswa yang tertarik dengan aspek teknis hukum laut. Penerjemahan ini direncanakan akan berakhir dengan diterbitkannya sebuah dokumen resmi yang diakui oleh lembaga terkait.

Tunggu perkembangan selanjutnya.

The Australia’s Submission of the Extended Continental Shelf (ECS): A Study on Its Impact to the Indonesia-Australia Maritime Boundaries and Indonesia

A Study on Its Impact to the Indonesia-Australia Maritime Boundaries and Indonesian Potential Claim over ECS

Abstract
On 15 November 2004 Australia submitted its claim over Extended Continental Shelf (ECS) to the Commission on the Limits of the continental shelf (CLCS) through the Secretary General of the United Nations. The submission was to confirm Australia’s claim over continental shelf beyond 200 nautical miles (nm) measured from its baseline. The United Nations Convention on the Law of the Sea (UNCLOS) states that every coastal state intending to claim continental shelf beyond 200 nm, is required to submit the claim together with supporting data and convincing arguments to the CLCS.
Australia’s documents of claims have been accessible in the internet through the UN Department of Ocean Affairs and the Law of the Sea (DOALOS)’s website. This is open for comments and critics from any other countries before a decision is made by the CLCS. Some countries have submitted their official comments concerning the Australia’s submission including, the US, France, East Timor, Japan, and Russia. Indonesia, being the geographically nearest country to Australia, has not submitted its comments to the Australia’s submission for unknown reason.
This paper is to criticize the Australia’s claim over ECS, study its impact to Indonesia-Australia maritime boundaries, and analyse potential response of Indonesia to the claim with regards to Indonesia’s national interests. To do this, a spatial and technical assessment will be required concerning Australia’s ECS claim and Indonesia’s potential claims. CARIS LOTS™, a specialised Geographic Information Systems (GIS) application, will be used to process spatial data required for the analysis.

Abstrak

Pasal 76 Konvensi PBB tentang Hukum Laut (UNCLOS) 1982 mensyaratkan bahwa sebuah negara pantai yang menginginkan klaim Landas Kontinen Ekstensi (LKE) yang melebihi 200 mil laut , wajib mengajukan klaim kepada komisi batas landas kontinen (Commission on the Limits of Continental Shelf, CLCS) melalui Sekretaris Jendral PBB. Sampai tulisan ini dibuat, Indonesia belum mengajukan klaim atas LKE kepada PBB dan masih dalam tahap mengkaji kemungkinan pengajuan LKE tersebut. Sementara itu, beberapa negara lain seperti Rusia, Australia, Brazilia, Perancis, Selandia Baru, sudah menyampaikan klaimnya dan dokumen mereka sudah dimuat di website Department of Ocean Affairs and the Law of the Sea (DOALOS).

Paper ini bertujuan untuk melakukan studi banding terhadap klaim LKE beberapa negara yang sudah diserahkan kepada CLCS. Studi banding ini dimaksudkan untuk mengkritisi kemungkinan pengajuan klaim LKE oleh Indonesia dengan mengambil pelajaran dari pengajuan klaim beberapa negara yang dianggap relevan. Yang akan dijadikan subyek studi banding adalah klaim oleh Australia, Brazilia dan Selandia Baru dengan fokus pada aspek teknis dalam konteks spasial/keruangan dikaitkan dengan kepentingan nasional Indonesia. Kajian ini bersifat tinjauan pustaka dengan menganalisis dokumen submisi klaim LKE negara terkait kepada CLCS.

Kajian ini diharapkan dapat menghasilkan temuan yang bisa dijadikan acuan oleh Indonesia dalam mengajukan LKE. Selain itu akan dianalisis juga kemungkinan sengketa yang muncul karena pengajuan LKE, terutama antara Indonesia dan Australia sebagai negara bertetangga.

Settling maritime boundary with neighbor Timor Leste

Opinion and Editorial in the Jakarta Post - August 03, 2006


I Made Andi Arsana, Yogyakarta

The world was watching when increasingly violent demonstrations wracked Dili, East Timor, a few months ago. The violence, which killed a significant number of people, made news headlines across the world. Then, last month, Mari Alkatiri stepped down as prime minister and was replaced with Jose Ramos Horta. This was very big news from the world's youngest nation.

This article, however, looks more at the relationship between Indonesia and East Timor after the riots. In particular, issues concerning maritime boundaries between the two states, which had not been negotiated at the time of writing.

Gosong Niger: Is it Another Ambalat?

I Made Andi Arsana

It seems that cases concerning international boundaries between Indonesia and Malaysia do not stop from arising. Ambalat, the latest case causing tension built last year was apparently not the last one. While the negotiation series of the Ambalat case are even being undertaken, another issue sparks. Gosong Niger is the one that is currently becoming a hot issue, as always, in Indonesia. Not sure whether such issue is a serious concern in Malaysia.

The issue sparked when the fishing ship of West Kalimantan’s Office of Marine Affairs and Fisheries happened to be located 0.7 nautical miles from the boundary line within Malaysian territory during conducting a survey. Malaysian Navy, Tentara Laut Diraja Malaysia, suspected that this is a territorial trespassing that Indonesian ship has done. Gosong Niger lies in the border area between Indonesia and Malaysia, where the case took place. It extends over an area of some 50 sq kilometres stretching from west to east (Tempo, February 2006). The term “gosong” is apparently not a proper English. It refers to a submerged ridge of alluvial sand in shallow water, which in English is known as sandbar. See Figure 1.

Figure 1 Gosong Niger

Another issue was then discovered that Malaysian Navy usually conducts patrol around Gosong Niger and does not allow Indonesian fishermen fishing in the area. Some sources said that the traditional fishermen generally do not know that the area is under Indonesian sovereignty as they could see Malaysian ship parking in the area almost everyday. Consequently, the Indonesian fishermen have no access to the natural resources around Gosong Niger.

With respect to the existing seabed boundary between Indonesia and Malaysia 1969, Gosong Niger is part of the seabed that is divided by the boundary line where two third of the seabed fall within the Indonesian side. With regard to this, the ownership of the sandbar is considerably clear. As there is a precise line, it should have been clear who own which seabed.

However, it has to be remembered that no territorial sea boundary has been established between Indonesia and Malaysia in that area (north of Tanjung Datu). In other words the two states have agreed a seabed boundary but have not yet agreed a boundary for the water column. This means that the arrangement for sovereignty over the territorial sea in the area is not yet clear. Consequently, no judgment can be made stating that Indonesian or Malaysian ship has done territorial trespassing. However, by de facto, the existing seabed boundary is, unfortunately, recognised as the territorial sea boundary as well. This might be the reason why Indonesia or Malaysia suspects that the activities within the territorial water were boundary infringements.

As two adjacent states in Borneo Island, Indonesia and Malaysia have overlapping claim with regards to territorial sea in the area of Gosong Niger. The absence of territorial sea boundary between Indonesia and Malaysia, consequently, leaves an uncertainty regarding the sovereignty over the territorial sea (water column). If Malaysians or Indonesians go beyond the boundary line, but still in the water column without touching the seabed, they do not infringe any agreement/law. The prosecution can only be made when Indonesians or Malaysians cross the seabed boundary line and conduct activities involving seabed of Gosong Niger.

Media says that Malaysia has established a permanent tourism service around the area and provide facilities for diving, swimming, and other aqua-tourism activities around Gosong Niger. If it is true, it might worth confirming that it is not an acceptable practice as the boundary between Indonesia and Malaysia has not been agreed. If the activities involve seabed exploration or exploitation, these can be considered as infringement.

Some opinions in Indonesia said that this is similar to the case of Sipadan and Ligitan, where Malaysia will finally be granted the sovereignty over Gosong Niger because it has been demonstrating effective occupation over the sandbar. It is actually not the case. There is a permanent and agreed boundary line between Indonesia and Malaysia in Gosong Niger, but not in Celebes Sea where Pulau Sipadan and Ligitan lie. The absence of permanent boundary line in Celebes Sea, ant the lack of legal official claims were the reason why the sovereignty over the two islands were disputed. In that case, the effective occupation (Effectivités) was a relevant consideration to decide the sovereignty over Pulau Sipadan and Ligitan. In contrast, the “ownership” of Gosong Niger has been made clear by the existence of a seabed boundary agreed in 1969. The infringement conducted by either Malaysia or Indonesia has nothing to do with its sovereignty.

This case is by no mean similar with Ambalat dispute. The Ambalat dispute, being in Celebes Sea, was due to the absence of permanent seabed boundary. In contrary, the seabed boundary in Gosong Niger has been clear so there is no need to establish a new seabed boundary unlike what is required with regard to Ambalat.

It seems that international boundary disputes have been one of Indonesia’s major problems lately. Many cases regarding international boundary, sovereignty and sovereign rights have caught everybody’s attention, including Ambalat case, island ownerships/disputes, Gosong Niger, border crime, ship piracy, etc. Many suggestions have been addressed to government and corresponding bodies but it seems that the reaction has been far for acceptable. Cases keep arising. It is understandable that the government is currently struggling with other bigger and more strategic issues such as corruption and natural hazards but it does not mean that the issue regarding international boundary and sovereignty/sovereign rights can be put in the last line and treated as the least priority.

My Thesis

It has been a while since my last posting.

I am reasonably busy lately with my thesis. Yes, the submission day is coming closer. I have to leave UNSW in less then two months. A flight ticket has even been booked for 28 March 2006. It is quite nervous to know that I will finally finish my thesis and leave for Indonesia.

Roughly, all chapter drafts have been written. Eight chapters were agreed to be compiled for my Master Thesis and most of them are currently corrected by Clive. Three chapters have been returned to me, even thouh none of them I have touched for revision. I am currently concentrating on checking the grammar of the last three chapters (6,7,8) before giving them to Clive for comments.

Honestly, I find it is hard to write in English. It is even worse because it is a scientific writing with all the rules of dos and don'ts. Referencing is the most important think, I believe. This is to avoid plagiarism, the one we all hate!

Btw, when started writing my thesis, I could not imagine how to write such a thick thesis with more than one hundred pages in it. Believe it or not, when you keep writing you won't realise that you have writen beyond the minimum pages you have to write. I have, so far, writen more than 135 pages, with more than 30 thousands words in it. What did I talk about in the thesis so I have written that much? Yes, that is the question I am always asking myself.

Anyway, no matter what happen, I have to finish my thesis on time. I hate having my scholarship extended! I will try hard and push myself till the limit so I don't need to extend my stay in Australia. Two years are more that enough. Not because I don't like Australia, I love being here in fact, but because I want to move on. There are still too many things to do. Indonesia is waiting for me, of that I am sure!

Tension builds over Ashmore Reef: Is it Indonesia's or Australia's?

- Opinion and Editorial, December 19, 2005
I Made Andi Arsana

Ashmore reef (a.k.a. Pulau Pasir) is currently being disputed by Indonesia and Australia.

If we talk about an island/reef/islet, we are talking about sovereignty. In dealing with sovereignty we do not consider distance.

If we talk about a state authority in the sea territory, we are dealing with sovereign rights, not sovereignty. Distance becomes the key issue as it depends on the distance measured from the baseline, commonly the coastline depicting the low water line. With regards to this, it is true that we need to consider maritime zones and boundary issues. Read more...

Ashmore Reef: Indonesia’s or Australia’s?

I Made Andi Arsana

In Indonesia, Ashmore reef (a.k.a. Pulau Pasir) is recently popular. The hot issue is that the reef has been disputed by Indonesia and Australia. Indonesian Navy’s Chief of Staff stated that Ashmore reef definitely is under the Australian sovereignty (Republika Online, 24 November 2005). This might be quite surprising for some Indonesians believing that Ashmore reef is Indonesia’s.

It is worth mentioning that Indonesian society should have learned much from recent cases regarding boundary and sovereignty. Reading news in the papers and electronic media, it is understandable Indonesians can be easily emotional and sometimes irrational. Legal, technical and scientific aspects are often beyond news’ concerns. Is it because Indonesians love sensation more than information?

Sovereignty vs. Sovereign Rights
If we talk about an island/reef/islet, we are talking about sovereignty. Dealing with sovereignty means we do not consider distance. The statement of Mr. Tanoni regarding the status of Ashmore Reef conflicted with Indonesian Exclusive Economic Zone (EEZ) is indeed not quite right. (Republika Online, 23 March 2003) Just because a reef lies within Indonesian EEZ, it does not necessarily mean that it belongs to Indonesia.

If we talk about State authority in the sea territory, we are dealing with sovereign rights, not sovereignty. Distance becomes the key issue as it depends on distance measured from baseline, commonly coast line depicting the low water line. With regards to this, it is true that we need to consider maritime zone and boundary issues governed by the United Nations Convention on the Law of the Sea (UNCLOS).

Ashmore: Whose Reef Is It Anyway?
The sovereignty over a reef cannot be carelessly decided. It is not depending on its distance to a State’s main land. It deals with legal aspect.

A website in the Netherlands reveals that Ashmore reef was annexed by Britain in 1878. Together with Cartier Island, Ashmore was transferred to Australia on 23 July 1931 and is then part of the Northern Territory of Australia (1938–1978). In 1978 Australia established Ashmore and Cartier Islands Territory and finally Australian government formed Ashmore Reef National Natural Reserves on 16 Augustus 1983. Of course we do not nave to trust the internet site. More intensive studies need to carry on.

CIA website, one of the resources people may trust, reveals similar facts. CIA’s World Fact Book confirms that Ashmore reef is under the Australian sovereignty. Another support also comes from GEsource website in the UK.

By plotting the coordinates of Ashmore Reef (12° 13.98' S, 123° 4.98' E) in the Indonesia-Australia EEZ boundary map, it is clear that Ashmore Reef lies within the Australian EEZ. This, implicitly, implies that Indonesia has acknowledged the Australian sovereignty over the reef.

From a historic point of view, it is true that the ancestors of Timor people came to Ashmore Reef since 1630s. However, Rais (2005) asserts that the Netherlands never secured the reef in its colonial territory and the government administering the reef was Britain. Indonesia could not claim Ashmore Reef just because their ancestors came there, did economic activities and died in the reef provided that the government administering the reef was not its predecessor (the Netherlands). In their article in Kompas (11 April 2005) Prof. Jacub Rais and J.P. Tamtomo assert that the Indonesian Proclamation of Independence secured all the former areas of the Netherlands (not others) as people in those areas had the same experience during colonialism.

It is indeed ironic that Indonesians (Timorese and others) who have been visiting and carrying activities in Ashmore Reef for hundreds of years (Kompas, 28 May 2005) are not entitled to own the Reef, while Britain (Australia), who “discovered” Ashmore in the nineteenth century, secures stronger rights. It is worth noting that modern law emphasizes legal claim rather than visits and activities. If it is true that Britain legally claimed and administered Ashmore Reef and the Netherlands did not protest, its sovereignty will obviously be Australia’s.

By contrast, Ferdi Tanoni states that there are strong evidences that Ashmore Reef were part of the Netherlands during the colonial era. He asserts that the implementation a regulation regarding sea cucumber and other marine biota collection around Ashmore Reef is a convincing evidence for its claim over the Reef. Unfortunately he did not specifically mention the document he referred. However, it this is true, it could possibly invalidate British Claim over the Reef in the eighteenth century.

Agreements between Indonesia and Australia
In 1971/1972, Indonesia and Australia agreed Continental Shelf (CS) boundary (seabed) where the boundary line located far North, close to the island of Timor (Indonesia). Some experts opined that it is not an equitable boundary. Apart from the unfairness and the failure of Indonesian diplomacy in the past, it is worth understanding that the agreement was signed before the UNCLOS came into force. Therefore, the quality of the agreement could not be judged using UNCLOS.

The Australian argument emphasized the principle of natural prolongation. The data available at that time suggested that the natural break of the Australian continent and Indonesian continent exists close to Timor Island, so that the CS boundary lies far from the median line favoring Australia. This practice was supported by legal development at that time. The ICJ’s judgment on 20 February 1969 regarding The North Sea CS case between Germany and Denmark, for instance, significantly considered geomorphology of the seabed or the principle of natural prolongation. In other words, Australian argument was supported by jurisprudence. However, the development post-UNCLOS tends to consider seabed geomorphology less. In the case of Libya and Malta (1985), for example, the ICJ decided that within 200 nautical miles, seabed geomorphology is irrelevant and the court’s judgment was based on distance principle.

It might be true that the CS boundary between Indonesia and Australia is inequitable. However, it is worth noting that the decision was with regards to the positive law applicable at that time. If required, Indonesia may renegotiate the boundary with Australia, provided that Australia agrees to do so. However, it is most likely that Australia does not want renegotiation.

Another agreement requiring attention is the 1997 EEZ boundary. Unlike the CS boundary, this is much more equitable as the border lies in the median line between the two States. Unfortunately, Indonesia has not yet ratified the agreement in its internal law.

Regarding Ashmore Reef, there is an MoU in 1974/75 allowing Indonesian traditional fishermen fishing around Ashmore Reef. Surprisingly (to Indonesia) Australia, in 2002/2003, restricted Indonesian fishermen from fishing in the area due to environmental conservation. This must attract the attention of Indonesian government and it should responsively clarify this as this endangers Indonesian fishermen’s life.

The Last Words
Undoubtedly, it is Indonesians obligation to keep the archipelago exists and united. However, clear understanding regarding legal, technical and scientific aspects are essential. Everybody should carefully analyze and be more critical toward every single issue regarding border conflict. A wrong decision may lead Indonesia to a huge material loss as well as reputation degradation as it might be considered as an emotional and irrational society.

The available legal evidences, so far, tend to suggest that Ashmore Reef is under the Australian sovereignty. However opinions and arguements sugesting that it is part of Indonesian Territory is worth to seriously consider. Let’s do our parts and let the governments do their best to achieve the most equitable solution for both sides.

Expert Advice

Intensive studies and good efort to build networks have slowly borne fruit. Started from teaching activities, now some even come to ask for expert advice. I still could not believe somebody asked me to provide my expert opinion regarding maritime boundaries :(

An Indonesian delegate came to Canberra last week searchig for data and advice regarding maritime boundary delimitation among Indonesia, Timor Leste and Australia. Through Pak Hanung of DKP, whom I taught during a short course in CMP, Wollongong University, I was invited to come and join the discussion. It was such a good opportunity as I can directly contribute to the real problem Indonesia is currently facing.

I met Collonel Sugito of Dishidros and alao Pak Kris, the acting Ambasssador of Indonesia for Australia. The discussion was good and also excellent contacts were made. I, in a very short period, wrote a short popular-scientific paper describing the options of maritime boundary delimitation between Indonesia and Timor Leste. Hope the opinion will help, even though just a bit.

Book Chapter

Still remember my presentation in the ICOC last September in Adelaide? Yes, the one about Indonesia-Timor Leste maritime boundary.

My presentation was apparently quite interesting, at least to Dr. Kingsbury of Deakin University (yes, right! I mentioned his name in my report too). He offered me to include my paper in his edited book. This is, of course, a very good offer. Clive and I (the paper is a joint-paper) then worked hard to edit the paper and broadened the scope not just to cover Indoensia and Timor Leste but also Timor Leste-Australia maritime Boundaries.

A distant collaboration was then taken place as Clive is in Wollongong and I am in Sydney. Guess what, we kept emailing every five minutes to discuss this and that. It was a very good virtual collaboration and we finally came up with a final draft with four figures. I created the figures myself using Corel Draw and those are driven from the analysis using CARIS LOTS. The reason why they have to be re-drawn because the book cannot contain colored image and also because the images coming directly from CARIS are not printing-ready.

Well, the chapter will be my first English publication in an edited book. What a good experience for a young academic like me!

Best of the Best

No, of course it is not about the famous movie :) This is about a suprising news coming to me yesterday. The Judges of the 32^nd Autralian Research Seminar decided that my presentation is the best presentation in ALL categories of the seminar. It was, undoubtedly, amazing (and surprising at the same time) as I don't really expect to be the winner.

FYI, I presented my research about maritime boundary delimitation between Indonesia and Timor Leste, which is actually part of my master thesis. The judges, consisting of UNSW, Leica Geosystems, and NSW Dept. of Lands [?], for the reasons that I don't really know, placed me as the best presenter in the session I was presenting in as well as the best presenter in all categories. Please have a look at my presentation, if you like.

Berhala in the JP

On Sept. 26, 2005 Antara official news agency carried a report on the concerns of a North Sumatra's provincial legislator regarding a website promoting Pulau Berhala as one of Malaysia's tourist destinations. When reading this, Sipadan and Ligitan come to mind. The two islands were secured by Malaysia when the International Court of Justice (ICJ) ruled that sovereignty over them rested with Malaysia in 2002.

In Indonesian minds this scenario raises disturbing questions: Is Malaysia now pushing its luck and seeking to secure small, isolated islands in boundary areas one by one? Is Pulau Berhala vulnerable and could there be a repeat of the Sipadan and Ligitan case? Read more...

Berhala: Another Sipadan and Ligitan?

I Made Andi Arsana

The news in ANTARA on 26 September 2005 was about the concerns of North Sumatra’s FPPP provincial legislative councils regarding a website promoting Pulau Berhala as one of Malaysia’s tourist destinations. This was addressed by Fadly Nurzal, a representative of FPPP. When reading this, Sipadan and Ligitan come in mind. The two islands have been secured by Malaysia as the International Court of Justice (ICJ) decided to award their sovereignty to Malaysia in 2002. Does Malaysia push its luck to secure one by one small islands in the boundary area? Will Pulau Berhala repeat the history of Sipadan and Ligitan? Let’s see what happens!

As far as I am concerned, there are at least three different islands called Berhala. The first island is the one referred by Nurzal in Malacca Strait, around 48 Nautical Miles from Port Belawan. The second Berhala is in Berhala Strait close to Riau Archipelago that has been a source of conflict between Jambi and Riau for such a long time. The last one is close to Sandakan, North Borneo, which has been a tourist destination and is fabulous for diving. The second Berhala is clearly Indonesia’s, while the third one is definitely Malaysia’s.

Unfortunately ANTARA did not clearly mention the website referred by Nurzal. Therefore it is not a hundred percent clear which Berhala Malaysia promotes as its tourist destination. If the island it promotes is the one close to Sandakan, Nurzal must have been careless in expressing opinion. Hopefully that is not the case.

If Pulau Berhala in question is the one in Malacca Strait, then it will be a different story. Indonesian government has to pay extra attention as this may lead to the loss of an island. Pulau Berhala, as stated by the Hidro-Oceanographic Office of the Indonesian Navy (Dishidros), is one of the 12 small islands which are critical due to their position in the international boundary area.

The other eleven islands are Pulau Rondo (Indonesia-India); Pulau Nipa (Indonesia-Singapore); Pulau Sekatuang (Indonesia-Vietnam); Pulau Marore, Pulau Mianggas and Pulau Marampit (Indonesia-Philippine); Pulau Batek (Indonesia-Timor Leste); Pulau Dana (Indonesia-Australia); Pulau Fani, Pulau Fanildo, and Pulau Brass (Indonesia-Palau).

Let’s look closely to Pulau Berhala in Malacca Strait and review the maritime boundary agreement between Indonesia and Malaysia.

In 1969, Indonesia and Malaysia entered into an Agreement dividing the continental shelf between the two countries in Malacca Strait and ratifications were exchanged on 7 November 1969. Ten points are agreed as the turning points of the boundary line.

Some opined that the agreement is not an equitable solution as Malaysia applied straight baseline connecting its outermost islands while it is not an archipelagic state. This causes the boundary line lies closer to the Indonesian side and is considered as inequitable. However, Indonesia and Malaysia have signed the agreement and it has been binding for both countries for such a long time. Now, it is not important to discuss how the boundary has been achieved but to obey the agreement, unless the boundary needs renegotiation.

Unlike the uncertainty of Sipadan and Ligitan as there has been no definite maritime boundary in Celebes Sea, the continental shelf boundary in Malacca strait should have made the status of Pulau Berhala clear. Based on the 1969 agreement, the International Boundary Study of the Department of State, US analyzed the boundary and found that Pulau Berhala belonged to Indonesia. This was clear in the analysis of the study, especially in the table of characteristics of the border points (The Geographer, 1970).

Experiences tell that the arguments of chain of title based on the history are often not strong enough to prove the ownership an island. Indonesia or Malaysia could refer the history to prove that an island belongs to it but often it is hard to agree. This is because there is no dateline since when such history should be considered. This was also the case when the ICJ decided the case of Sipadan and Ligitan by considering the principle of effectivités. Historic arguments proposed by Indonesia and Malaysia could not convince the court and were rejected. The principle of effectivités looks more to the effective legal action done by countries in question to the islands. The court found that Malaysia, proceeded by the Great Britain, have done much more to maintain Sipadan and Ligitan Islands. Therefore the "sovereignty over Pulau Ligitan and Pulau Sipadan belongs to Malaysia”

In the case of Pulau Berhala, we will also assess the principle of effectivités and see how it goes.

In 1984, Indonesian Government built a lighthouse in the Island and since has been maintaining the lighthouse by continually assigning lighthouse attendants. This can be considered as a legal action proving that Indonesia has done the appropriate things as the owner of Pulau Berhala. Maintenance of the lighthouse requires Indonesian Government to take care the environment; otherwise the lighthouse will not be able to function properly. This also proves the role of the Indonesian Government in Pulau Berhala fulfilling the principle of effectivités. Therefore, based on the principle of effectivités, Indonesia deserves to be the legal owner of Pulau Berhala.

In a technical perspective, a spatial assessment needs to be done by plotting the coordinate of Pulau Berhala together with the border lines in an appropriate-scaled nautical chart. By plotting the location of Pulau Berhala and the boundary line in a chart, it will be clear whether Pulau Berhala lies in the side of Indonesia or Malaysia.

We will see how Indonesia and Malaysia deal with this kind of problem. It is very important for all citizens to clearly understand the problem and support the governments to do their best. Instead of being over-reactive, let’s be calm and patient.

Indonesia Council Open Conference, 2005

[Adelaide, 26-27 September 2005]

Being the only surveyor presenting in a social science conference is an interesting experience. The Indonesia Council Open Conference, 2005 is an annual conference hosted by Flinders University in Adelaide with the support of The Flinders Asia Centre and the Inside Indonesia magazine, where my presentation is the only technical paper among many social papers presented. Being a social science conference, almost all presentations are about to social issue, especially, of the Indonesian society.

The topics presented were vast and diverse from the literacy issues to Indonesia's future. Most of the topics might not be interested for a surveyor/geodesist. Therefore it is not important to discuss each topic here.

I presented my paper, "Maritime Boundary Delimitation between Indonesia and Timor Leste: A Technical Perspective", on 26 September 2005 in the session of Boundaries, migration and foreign policy. Being the only technical paper, the presentation attracted intention form most audiences and also drew some interesting questions and comments. Different from the other presentation which were filled with words, my presentation was dominated with graphics and pictures [maps]. All the technical aspects I introduced coupled with legal consideration [law of the sea] in defining maritime boundaries were quite interesting to the audiences. This, I belive, was a good moment to remind them surveryor's contribution to such an international matter (i.e maritime boundaries).

A senior lecturer from Deakin University, Dr. Damien Kingsbury gave very good comments and suggestions regarding my research, as he significantly knew East Timorese views about the maritime boundaries in question. He also promised to introduce me to an East Timorese geographer who is currently dealing with the Boundary issue. This will be a very good information resource.

To sum up, apart from the fact that the conference is more about social science, it was still a very good event to share ideas, especially to enrich the resource of my research as a multi-disciplinary one.

For more information please visit the website. Please also contact me for a proceeding containing colection of abstracts.

Giving a Lecture in Wollongong University

Surprise!!!

Yes it is for real. I've just given a lecture in Wollongong University at the Center for Maritime Policy. Guess what! The lecture was for master degree, not for undergraduate. How come? How can a master student give a lecture for master degree? Ask Clive for the answers :)

The students are all Indonesians from [nearly] all around Indonesia. Some of them are from Department of Fisheries and Marine Affairs, while some others are from Regional Governments.

They looked very entusiastic listening to my lecture about Indonesia's Internal Boundary Issues. It was understanable as it was the only lecture in Bahasa Indonesia. A student, jokingly, said that my lecture is the only lecture he can understand, making his colleagues laugh.

It was a very good experience!

Map Asia 2005, Jakarta 22-25 August 2005

[an epilogue]

Map Asia 2005 is the 4th annual conference organized by GIS Development PTE. Ltd. - Singapore in collaboration with Indonesia’s Bakosurtanal, Asosiasi Perusahaan Survey dan Pemetaan (APSPI ) – INDONESIA, Center for Science, Development and Media Studies (CSDMS) - India,and the Asian Institute of Technology - Thailand. The conference was undertaken in Mulia Hotel, Jakarta Indonesia on 22-25 August 2005. Bellow are some important notes about the conference.

Registration and Opening Ceremony
The registration started at 10 am and ended at 4 pm when the opening ceremony began. The conference was officially opened by The Indonesian Minister of Research and Technology, DR. Kusmayanto Kadiman, who is an alumnus of the Australian National University. Other speeches were also delivered by The Head of Indonesia’s Bakosurtanal (MR. Matindas), the president of Map Asia 2005 (Prof. Narayanan), and local organizing committee (Mr. Purnawan).
Hitting the “Gong” officially inaugurated the conference and all its programs including exhibitions, technology shows, and workshops. The ceremony ended with an inaugural dinner in the Grand Ball Room of Mulia Hotel.

Plenary and Keynote Sessions
The first day [23 August 2005] started with plenary session I: empowering People through Geospatial Information with three speakers. This was followed by keynote session I : Web GIS with also three speakers. The second day [24 August 2005] has one plenary session and one keynote session with total of 5 speakers. The plenary session was on Regional Cooperation while the keynote session is about Large Scale Mapping. In keynote session, speakers excessively discuss the advance in large scale mapping and the availability of large scale data in the internet. Google Earth was one of the phenomena that discussed a lot.

Seminar Sessions
There were three seminar sessions in the conference. I presented my paper in one of the seminar sessions: Marine and Coastal GIS which was chaired by Drs. Michiel Damen from ITC, the Netherlands. My paper is “Ambalat: A Spatial and Technical Perspective”, penned with Clive Schofield of The University of Wollongong. Other seminar sessions are Space Program and RS, and Disaster Management distributed in some parallel sessions. That is why, it was impossible to attend all presentations as some are delivered at exactly the same time.

Technical Sessions
This consists of 16 sessions: Geological Applications; Water Resources; Land Information System; Open Geospatial Consortium workshop on interoperability; Disaster Management; Traffic and Transportation; Precision Farming and Agriculture; Environment and Forestry; Urban and Town Planning; Digital Image Processing; Web GIS/Internet GIS; Photogrammetry and 3D Visualization; Database Design and Ontologies; Land Cover, Use and Change; Emerging Applications; Natural Resource Exploration and Planning. Similar to seminar session, this session was also distributed into some parallel session in different venues, so visitors had to decide which presentation to attend.

Networking
The Conference, to me, was a very good event where we could start building international networking among experts, industries and users of geospatial technology. Some opportunities were available such as software share, training, data exchange, collaborative research, etc. Some industries even freely distributed data, software, magazines and books to exhibition visitors.

Excercising Maritime Boundary in Timor Sea

Robust Equidistance Line
Figure bellow depicts equidistance lines in Timor Sea that consist of two different segments. Segment CB4-a is the adjacent equidistance line between West Timor and Timor Leste, and is the elongation of land border in Mota Masin. Segment b-c represents the median line between Timor Leste and the Indonesia’s archipelagic straight baseline along Pulau Leti, Pulau Moa, Pulau Lakor, Pulau Maetimearang with zero effect given to Pulau Jako. On the other hand, segment b-d is similar to segment b-c only with full effect given to Pulau Jako.

Final Boundary Line
To finalize the boundary in Timor Sea, especially the one starting from the point between Pulau Jako and Pulau Leti going down to the boundary between Indonesia and Australia, half effect has been given to Pulau Jako. The blue line between two black lines is the final boundary line in Timor Sea at the East side. Meanwhile, the equidistance line departing from Mota Masin at the West side of Timor Sea has been left without any shift. This is because there is no significant feature to consider and neither relevant circumstance that influence the equidistance line. The following Figure shows the final boundaries in Timor Sea.

Excercising Maritime Boundary in Ombai Strait

Robust Equidistance Line
Equidistance lines in Ombai Strait shown in figure bellow consist of four segments. The first segment is the line starting from common basepoint CB₁ to point a, which represents the equidistance line between Oecussi and West Timor as the elongation of land border in Noel Besi. The second segment is the a-b segment, representing median line between Pulau Batek and Oecussi with full effect given to Pulau Batek. Segment b-c is the median line between Oecussi and Indonesia’s Pulau Pantar and Pulau Alor. Similar to the first segment, the last segment of c-CB₂ is the equidistance line between Oecussi and West Timor, as the elongating of land border in Noel Meto.

Final Boundary Line
The maritime boundary in Ombai Strait, as depicted in figure bellow, has been obtained by changing the effect given to Pulau Batek. The significance of Pulau Batek is lower than that of Oecussi; therefore the weight given to Pulau Batek is lower than Oecussi. In this case, half effect (0.5) is given to Pulau Batek that causes the median line shifts toward it. Consequently, Oecussi possesses larger maritime zone than before.
