【 摘 要 】

Indonesia is a country with the largest geothermal potential resource in the world, estimated of 28,617 MW or equivalent to 40% of the world's geothermal potential. Geothermal energy is environmentally friendly and quite economical compared to fossil energy. Seulawah Agam is one of Indonesia's geothermal fields that has several manifestation zones, including Ie Brô uk (BH1 and BH2) manifestations. The analysis for this study was conducted by acid-base titration, UV-Vis Spectrophotometry and Atomic Absorption Spectroscopy (AAS). The data analysis of cations and anions were plotted in liquid chemistry worksheet plotting spreadsheet version 3 Powell geoscience September 2012 by Powell and Cumming. The type of manifestation fluid is bicarbonate, obtained from the geoindicator Cl-SO4-HCO3, while the water condition is immature based on Na-K-Mg ternary diagram. The Ie Brô uk reservoir temperature was 289 ° C and 291 ° C obtained from Na/K geothermometer Tonani (1980) and Na/K Giggenbach (1988) respectively. Therefore, the Ie Brô uk manifestation classified as a high-Temperature geothermal system.
