Optimization of Determination of the Number of Fisheries Supervisory Vessels in the Fisheries Management Area -713 Using Genetic Algorithms

The Indonesian Fisheries Management Area (FMA) consists of eleven regions, one of which is FMA-713. FMA-713 includes Makassar Strait Waters, Bone Bay, Flores Sea and Bali Sea with an area of 203,920 Mil². Problems that often occur in FMA-713 include high illegal fishing, overfishing, fishing with bombs. The influencing factor is the lack of Fishery Surveillance Vessel owned by the Ministry of Maritime Affairs and Fisheries which are assigned to FMA-713. The purpose of this research is to choose the optimal number of fishery surveillance vessel to operate in FMA-713. To solve this problem, the method used is the Genetic Algorithm method. Genetic Algorithm is the most widely used optimization method to solve multi-objective problems. The results of the optimization recommend the number of ships operating in FMA-713 are six ships of type A-B-B-B-C-C with an achievement area coverage of 209,342 Mil² and operational costs of IDR. 1,621,184,100. The findings in this study can be used as a consideration by the Government to determine policies to improve Indonesia's marine security.
