Determination of the Provincial Sea Area Boundary in Indonesia Archipelagic Regions using Cartometric Method

The marine areas management authority for provinces in Indonesia has so far been 12 miles from the coastline. The Draft Law of Republic of Indonesia concerning the Development Acceleration of Archipelagic Regions, which has been proposed since 2017 and is currently waiting for its ratification. It gives wider authority to provinces with archipelagic characteristics. The basis for determining the territorial sea boundaries of a province with archipelagic characteristics uses the principle of an archipelagic state, which is to draw the outermost line from the islands in the province. The method used to determine the boundaries of the area is cartometric method. Cartometric method is tracing/drawing boundary lines on work maps and measuring/calculation of points positions, distance, and area coverage using base maps other map as complementary. If this Draft Law is successfully ratified, then the area of marine management for the province with archipelagic characteristics will increase and there will be hope for increased welfare. The results of the study in 3 (provinces) with archipelagic characteristics, namely North Maluku Province, Maluku Province, and Riau Islands Province showed an increase in marine management area between 72.36% - 158.46%.
