Human’s dependence on fossil resources as the primary source to produce energy can result in an energy crisis because the decreasing of fossil resources. Therefore, an alternate power source to replace fossil resources is needed. One of them is to utilize the geothermal resource. A geothermal resource is a renewable energy resource and is also environmentally friendly which is why this geothermal energy resources began to be widely developed in Indonesia. The utilization of geothermal resources in Indonesia is the right choice, considering that the Indonesian geothermal resources is up to 40% of the world's geothermal reserves. <br /> <br /> <br /> Volumetric method is used to determine the amount of the geothermal energy that can be converted as an energy source. Volumetric method is a method to estimate the reserves of geothermal energy in a geothermal reservoir. The amount of geothermal energy reserves in a reservoir depends on its physical parameters required as an input to the volumetric equations. The assumption used in the calculation in this study includes the recovery factor by 25%, electricity conversion factor of 15%, and the final temperature of 180oC which is the minimum temperature to drive the geothermal turbine. The calculation using the volumetric method that is used in this study will give us a value of geothermal energy reserves in X geothermal field of about 375,03 MWthermal and electric potential of about 56,25 MWelectric for 25 years of exploitation process and its value will decrease over time.
