asi sulfat so4 yang dominan (95% untuk sampel i dan 97% untuk sampel ii). pada diagram segitiga na-k-mg, fluida menunjukkan kondisi yang belum setimbang (immature water) karena fluida telah bercampur dengan air meteorik. berdasarkan analisis data geokimia daerah penelitian ditunjukkan bahwa adanya keterkaitan dengan sesar ceunohot yang berarah timur laut ke barat daya sebagai pengontrol aliran fluida panas bumi. kata kunci: diagram segitiga ternary, fluida panas bumi, sesar ceunohot, zona fluida abstract an analysis of the flow of geothermal fluid has been carried out in the jaboi geothermal field, sabang. this study aims to obtain a zone of geothermal fluid flow in relation to faults / faults. this research was conducted by the titration method and atomic absorption spectrophotometer (aas). sampling was carried out at two hot spring locations, namely crater i and crater iv. for sample testing carried out in a standardized laboratory. data processing is done through comparison of chemical fluid content and interpretation of ternary triangle diagrams. the triangle diagram includes cl-so4-hco3, cl-li-b and na-k-mg to determine the characteristics of geothermal fluids. based on data that has been processed and correlated with other supporting data (local geological conditions, magnetic, and temperature) shows a relationship that affects each other with the presence of faults. the analysis shows that geothermal fluid in the upflow zone is characterized by a dominant so4 sulfate concentration (95% for sample i and 97% for sample ii). in the na-k-mg triangle diagram, the fluid shows an immature water condition because the fluid has mixed with meteoric water. based on the analysis of the geochemical data of the study area, it was shown that there is a connection with ceunohot fault trending northeast to southwest as the controller of the flow of geothermal fluid. keywords: ternary triangle diagram, geothermal fluid, ceunohot fault, fluid
