This research aims to develop a hybrid power generation system based on load data from the Guest House on Matakus Island. Additionally, the study aims to evaluate the effectiveness of renewable energy power generation at the Guest House on Matakus Island and analyze the techno-economic aspects of the hybrid power generation system. Global Horizontal Irradiance (GHI) solar data and average wind speed data from Matakus Island were used to design a system combining solar PV, wind, diesel generator, and batteries to achieve an optimal configuration. The research findings indicate that the configuration with 5.75 kW solar PV, 3 kW wind, 5 kW diesel generator, and 18 kW battery is the optimal setup, capable of achieving fuel savings and reducing the Levelized Cost of Energy (LCOE) to Rp. 4362/kWh. The implementation of this hybrid power generation system successfully increased the Renewable Energy (RE) share to 83.8%, with an annual operating cost of Rp. 28.5 million. This configuration also reduced CO2 emissions to 1587 Kg/year with a fuel consumption of 606 L/year, contributing to environmental and climate change mitigation efforts. Moreover, the system achieved stability in producing a steady output voltage and meeting the load requirements of the Guest House on Matakus Island with a peak load of 3.42 kW. The use of the diesel generator as an active backup when the energy supply from renewable sources is insufficient demonstrates the efficiency and reliability of the system in providing the necessary electricity supply for the operation of the Guest House on Matakus Island. Furthermore, through analyzing various orientations for solar panel installations, it was found that the efficiency of solar panels facing North in a PV Tree-shaped arrangement could provide an annual energy output of 9211 kWh/year. Thus, this renewable energy-based hybrid power generation system proves to be an effective solution in meeting the electricity needs on Matakus Island.
