Geothermal System of Mt Pancar and Its Significance for Direct Use

Abstract

Mount Pancar Geothermal System is located in West Java 60 km from Jakarta. Three surface manifestations are located in Kawah Merah, Kawah Hitam, and Kawah Putih. This study aims to know the geothermal system and its direct use on Mt. Pancar. The research method is divided into several stages, introduction includes the literature study, data collection includes the measurement of temperature and pH in several surface manifestations of Mt. Pancar, and interpretation. The secondary data are retrivied to complete geological information of Mt. Pancar. Mt. Pancar geothermal system includes a convection-volcanic field type and has high relief. The type of manifestation that can be found in Mt. Pancar is hot spring with neutral fluid type. The fluid temperature of the surface manifestations is about 45 to 67°C with pH 6,8 to 8. The presence of surface manifestation confirms that geological structures trending from Northeast to Southwest, play a significant role to circulate the heated fluid in the subsurface and subsequently to the surface. Mt. Pancar geothermal prospect can be used directly (direct use). The utilization is in the form of the Mt. Pancar area as nature tourism, hot spring baths, camping area, outbound (flying fox), tracking downhill. In addition, recommendations other utilization can be applied by society and stakeholders such as aquaculture. The concept of aquaculture utilizes the manifestation of geothermal with heat exchanger into the fish breeding pond.
