【 摘 要 】

Banjarnegara and Cisukarame are potential areas for geothermal development. This research was conducted to obtain geothermal fluid characteristics, reservoir temperature, geo-thermometer and heat loss. Reservoir temperature is determined based on geothermometer calculations of Na-K-Ca, K-Na-Mg and Na-K. This type of manifestation like hot springs, it can be used to calculate the amount of heat loss. There are four geothermal reservoirs in the Banjarnegara area. Based on the analysis of the geothermometer value, reservoir 1 until 4 temperature is around 81°C - 374°C, the heat loss value reaches 31.6 MW. Beside it, in Cisukarame areas, the highest value of geothermometer temperature average 185°C - 212°C, the heat loss value obtained 48.3 MW. Heat loss value is used to determine the geothermal potential for build prospect power plant. Thus, a more efficient ratio of temperature and heat loss value is Cisukarame area, but both of them are potential for geothermal power plants development.
