In 2060 or sooner the Indonesian government wants to achieve net-zero by converting the use of fossil-fuel energy to renewable energy, so we conducted research related to geothermal energy in the Wapsalit area, Buru Regency, Maluku Province, Indonesia. This research was conducted with the analysis of gravity method. The result we got is a complete Bouger anomaly map with an anomaly range of 40-61 mGal. Then a 1D spectral analysis was performed to determine the regional depth estimate and a value of 2455,175 meters was obtained, with a spacing of 250m, a window width of 15 was obtained which was used for the moving average separation method. Two anomaly separation methods are used in the form of moving averages and second order polynomials. The results of the residual moving average anomaly were chosen because they are in accordance with the geological conditions and then an A-B modeling path was made which was made forward modeling of the trajectory. The anomaly values obtained from the model are relatively fit to curve.
