I ndonesia is an area that is included in the ring of fire, therefore Indonesia has thegreatest geothermal potential. Geothermal potential is closely related to thepresence of geological structures. This encourages researchers to find out moreabout the effect of structure on geothermal formation. The research area is locatedin the Cipanas and surrounding areas, Cipanas District, Lebak Regency, BantenProvince. The study was conducted to determine the geological conditions and therelation between the presence of manifestations and the influence of structures onthe area. Data retrieval by geological mapping and solid measurements in the fieldusing linear scanline method supported by the Fault Fracture Density method. Thegeomorphology of the study area is divided into five units, namely theGeomorphology of the Hills Slashed by the Sharp Cipanas Fault Zone, theGeomorphology Unit of the Serendet Intrusion Hill, the Geomorphology Unit of theIntrusion Ponggo Hill, the Cipanas Geomorphology Unit, the Overlapping VolcanoGeomorphology Unit. The geology of the study area is divided into five units,namely Dasit Unit, Claystone Unit, Andesite Unit, Limestone Unit, and BrecciaUnit. The geological structure in the study area is divided into 5: Horizontal FaultRaising Hamberang, Horizontal Fault Menganan Luhurjaya, Horizontal MengiriCipanas, Horizontal Fault Menganan Cipanas, Flat Fault Raising Cipanas, andWirajaya Anticline Lipatan. The Cisolok area geothermal model shows the outflowzone, permeability zone, and volcanic hydrothermal type in the form of high reliefliquiddominated system.
