Makassar Strait is located between two big islands of Sulawesi and Kalimantan. The geographical location of the Strait of Makassar is included in a safe area against disturbance of regional geological structures so that it is suitable for developing OTEC (Oceanic Thermal Energy Conversion). OTEC is one of the technologies to generate electrical energy by utilizing the differences in deep ocean temperature and near surface waters by looking at the depth and geological structure that developed in the area. The method used in this research is remote sensing to analyze bathymetry / depth, sea surface temperature (SST) and fault fracture density (FFD) which from the analysis result will be obtained by the prospect zone to be developed by OTEC. Based on the assumption that the temperature used is 25 ° C obtained by the average depth that can be developed OTEC is -838 m with an area of 468,448 km2. Where the closest distance the location that can be used for OTEC development is 18 km from the nearest island is Sulawesi Island. In its use OTEC has a drawback where to pump water from deep depth will require considerable energy so that to overcome the problem can be applied dual turbine application to cover the lost energy when pumping. OTEC power potential calculations obtained 8,557.32 MW in the delineated area. It can be concluded that bathymetry, SST, and FFD analysis can be used for delineation of prospect zones in OTEC development in Makassar Strait.
