Geothermal energy is one source of renewable and sustainable energy. Geothermal commonly find in Indonesia which has many active volcanoes such as, in Sumatra, Java, Kalimantan, Sulawesi, Maluku and Papua. Geothermal comes from the earth's surface, or more precisely under the earth's crust. At that area there is a magma which is very hot and mobile that formed naturally by molten rocks. Magma also come from radioactive materials such as uranium and potassium. Geothermal energy is very promising because beside as renewable and sustaible energy its energy force greater than oil and natural gas. Therefore, do not be surprised if this geothermal energy was developed to be an alternative energy. In determining the large reserves of geothermal energy that can be utilized as an alternative energy source with a volumetric method. Volumetric method is a method which used to calculate and determine the amount of geothermal energy reserves contained in the reservoir field or potential geothermal areas. The amount of geothermal energy reserves in a reservoir is really depend on the required physical parameters values as input values in the volumetric equations. Beside that, the values used as input to the volumetric equation there also used value based on assumptions. The parameters that used as an assumption in this calculation are the initial reservoir temperature at , the density of water is of 833.68 kg /m2, internal energy 964.238 kJ/kg and electric conversion factor 10%. By utilizing the value of these parameters, can be obtained the magnitude of geothermal energy reserves that available to be utilized within a period of 50 years is 322.08 MWt and geothermal energy that available to be is 32.21 MWe.
