Physical and Chemical Characteristic of Geothermal Manifestations in Talaga Bodas, West Java, Indonesia

Abstract

As the time goes by, geothermal energy is becoming one of the greatest alternative energy sources in the world. Geothermal systems usually occur in an area which has a lot of volcanic activities, such as Indonesia. One of the areas in Indonesia which has potential is located in Telagabodas, West Java. A geological and geochemical approach is used for this study to determine the characteristics of the geothermal manifestation. Mount Telagabodas has manifestations in the form of mudpools, solfataras and hotsprings. From the physical and chemical data, including the presence of chloride (Cl) water, acid sulphate water (SO4) bicarbonate water (HCO3), pH, TDS, and EC, the geothermal manifestations can be characterized as immature, indicating that the water in the geothermal system is mixed or the geothermal system has a shallow ground water source.
