| Summary: | 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.
