According to UNCLOS (1982) Indonesia is an archipelagic state with more than 17 thousand islands and a sea area of about 5.8 million km2. This can be done to optimize the wealth owned by examining the outer boundaries of Indonesia's sovereign territory. According to Government Regulation (PP) number 38 of 2002 concerning the geographical coordinate list of the points of the base line of the Indonesian archipelago that changes can be made to the list of geographical coordinates that already exists. The changes are used to obtain an optimal distribution of base point distribution for the maximum area of Indonesian waters. This research was conducted using two kinds of concepts, namely Convex Hull and Concave Hull, as well as three kinds of methods, namely Jarvis March and Graham Scan to produce Convex Hull and Alpha Shape for produced a Concave Hull. The results of the research for Convex Hull method cannot be used for the determination of the Base Point in the Sulawesi Sea because the geometric shape of its island produces a line of line segments a base that does not comply with the 1982 UNCLOS agreement. The Concave Hull method threshold of 0.35 produces a more optimal base point than the base point listed in PP no. 38 of 2002 with an additional inland sea area of 9765.28 km 2 and in accordance with the rules apply.
