Indonesia, as the world's largest archipelago, has great potential in harnessing marine renewable energy. With its vast coastline and Exclusive Economic Zone, the country has abundant marine resources that exceed its energy needs. This study aims to assess the influence of regional phenomena on sea surface temperature variability and thermal resource potential by Ocean Thermal Energy Conversion (OTEC) in the waters of Indonesia's Exclusive Economic Zone (EEZ). The scope of this research includes analyzing the influence of phenomena such as El-Niño Southern Oscillation, Indian Ocean Dipole (IOD), and Madden-Julian Oscillation (MJO) from January 2004 to December 2020. The data used in this study included ocean temperature data from the European Union Copernicus Marine Service Information (CMEMS) with a resolution of 0.083°. OTEC resources were calculated through the difference in ocean temperature at 20 m and 1000 m depth. The results showed that the total potential OTEC power that can be generated in Indonesian waters is 536.01 GW with a total potential area of 3,081,853.25 km2 . When the El Niño phenomenon occurs, it causes a decrease in OTEC power with a decrease in power of -128.197 GW and when the La Niña phenomenon occurs, it causes an increase in power with an increase of 137.616 GW. When the IOD is positive, there is a decrease in OTEC power with a decrease of -13.053 GW. During Negative IOD, there was an increase in OTEC power with the largest increase of 3.583 GW. The results also show that the MJO phenomenon also affects OTEC power, with an increase in power of 334.51 GW.
