Preliminary Research of Using Ocean Currents and Wind Energy to Support Lighthouse in Small Island, Indonesia

This study was aimed to get preliminary result, which review potential of utilizing ocean surface current and wind energy as energy source of lighthouse in Small Island. The data was acquired from field observation and from satellite. Ocean current speed in Berhala, Anambas, and Biawak island have their mean on 0.135 m/s, 0.055 m/s, and 0.272 m/s, meanwhile the ocean surface wind speed has its mean on 0.220 m/s and 3.032 m/s. Three years satellite data showed that Miangas island has the highest mean speed (0.835 m/s) of ocean current and Biawak island has the smallest one (0.154 m/s), whereas the highest mean speed (4.848 m/s) of ocean surface wind was in Rondo island and the smallest one (1.438 m/s) was in Berhala island.
