Abstract: Indonesia has a geothermal energy resource potential of 40% of the world's potential and only 8.9% of Indonesia's geothermal potential has just been utilized. The spread of various geothermal locations in Indonesia will affect the characteristics of Geothermal Power Plants with different process types, so an analysis is needed to compare geothermal process technology and the conditions of the power generation system between flash steam and binary cycle to find out the technology. geothermal process and suitable system conditions at the Lahendong area expansion location. In this research, simulation of double flash steam and binary cycle with regeneration were carried out and the results were then analyzed based on the highest power output and efficiency. It was found that the double flash steam system produces a power of 3125 kW with a thermal efficiency of 89.8%. Meanwhile, the binary cycle system with generation produces a power of 5433.25 kW with a thermal efficiency of 8.68%. Based on the simulation results that have been carried out, the suitability of the process for the expansion of the Lahendong Area Geothermal Power Plant location uses binary cycle technology with a binary cycle with generation system.
