2D Geological Structure Identification in Mount Ciremai Geothermal Area using the GGMplus Data

West Java’s Mount Ciremai holds substantial geothermal potential, marked by hot spring manifestations, which can be an alternative energy source. This research utilizes the GGMplus satellite gravity method, employing First Horizontal Derivative (FHD), Second Vertical Derivative (SVD), and 2D inversion to analyze the geothermal area’s geological structure and subsurface conditions. The results reveal fault structures, including reverse and normal fault types in Mount Ciremai. Specific details for both the Pejambon and Sangkanhurip lines and the Pejambon and Ciniru lines indicate distinct layers with varying densities (2.4 – 2.7 g/cm 3 ) and depths. These layers comprise pyroclastic flow deposits, andesite-basaltic rock, caprock (clay rock), and a reservoir (sandstone), shedding light on the geothermal potential of this region.
