The marine fisheries sector in Indonesia has a potential to be a fishing industry which is directly processed in the high seas. Fisheries potential should be in line with potential energy sources in the region. Energy sources that have the potential to support the fishing industry include floating solar PV, ground mounted PV and generators. The purpose of this study is to investigate three potential energy sources that are suitable to be integrated with the fishing industry in three regions of Indonesia. The method used to analyze energy costs and optimize the energy needed for fishing industry is using HOMER Pro software. Ground mounted PV produces the lowest average energy costs in Bitung at $ 0.157/kWh, but does not include the cost of land for solar PV construction. On the result, the average energy cost in Bitung is $ 0.1898/kWh, its shows that the best way to increase the effectivity of its industry is creating a floating solar PV technology system.
