At present, the depletion of fossil energy resources will have a significant impact on every aspect of life in Indonesia. One effort to overcome this problem is by conducting research to look for renewable energy sources. This study uses the Organic Rankine Cycle (ORC). The types of refrigerants used in this study are R141b, R245fa, and R123 using the Aspen plus Program Simulation. This study focuses on the working fluid R141b, R245fa, and R123 on the ORC as a 1 kW scale electric energy generator. The results obtained from the Aspen Plus Program Simulation in the ORC Cycle use working fluids R141b, R245fa, and R123 at a pressure of 3 bar to a pressure of 10 bar at a temperature of 95 ° C. The maximum efficiency produced is 8.65%, 7.79%, and 8.36%. The turbine power produced is 1005 watts, 896 watts, and 770 watts. From the simulation results used in the ORC working fluid R 141b has an Efficiency and Power value that is best used as a 1 kW electric energy generator with an efficiency value of 8.65% and 1005 Watt Power.
