Indonesia is an archipelagic State with 33 provinces and hundreds of regencies, which is now implementing regional autonomy. The regions that have sea territory are given the authority to manage natural resources therein. This provides Indonesia with the challenges of regional maritime boundary delimitation between provinces or regencies/cities. This is governed by the Law No. 32/2004, which deals with local government affairs including regional authority in the "sea territory". It regulates entitlements to maritime areas and maritime boundary delimitation in cases where overlapping claims between provinces or regencies/cities arise. Technical guidelines on regional boundary settlement have also been issued by the Ministry of Home Affairs through a regulation called Peraturan Menteri Dalam Negeri No. 1/2006 (hereinafter referred to as Permendagri No. 1/2006).

This paper is aimed at addressing technical aspects of maritime boundary delimitation between two provinces in Indonesia. The case study is for the Provinces of Bali (Bali) and Nusa Tenggara Barat (NTB). This paper analyses the determination of regional authority in the sea territory of the two provinces, which was done cartometrically based on Permendagri No. 1/2006. This includes the definition of baselines, maritime claim simulation, overlapping claim identification, and theoretical maritime boundary delimitation by employing the equidistance principle.

It has been identified that there are potential overlapping claims between Bali and NTB in the Lombok Strait that requires delimitation. CARIS LOTS™, specifically designed GIS software for maritime boundary delimitation, was employed as an assisting tool for this research. This paper presents options of maritime boundaries, which might be one of the alternatives that the government of Bali and NTB may consider in the real delimitation. In addition, this paper, in general, is expected to provide relevant information for local governments in Indonesia in dealing with the recently-emerged issue: regional maritime boundary delimitation.

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.

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...
