IKN Nusantara was officially made as the new capital of the country which was previously DKI Jakarta, then moved to East Kalimantan based on Law No.3 of 2022 on January 18, 2022. However, several villages in the zero point location of IKN Nusantara still experience a significant clean water crisis. This study aims to design a hybrid power generation system to supply submersible and suction pumps for clean water utilities. Two design alternatives are offered, those are solar-wind hybrid system and solar-biodiesel hybrid system. The research will focus on the area around the central government of IKN Nusantara located in Bumi Harapan Village and Bukit Raya Village. The software tools PVsyst, Homer Pro, and SketchUp will be used for design simulation and system calculations. The primary objective is to provide a continuous supply of clean water according to the residents' needs. The best solution identified is the solar-biodiesel hybrid system. The design includes solar power plant with a capacity of 2.2 kWp and biodiesel power plant with a capacity of 2 kW, along with a solar pump inverter with a capacity of 3 kW. The study results indicate that the power generation system can produce 5,510 kWh/year, with an effective power absorption by the pump load of 4,109.9 kWh/year during operating hours from 07:00 to 15:00 local time. The levelized cost of electricity is Rp3.987,85/kWh for Bumi Harapan and Rp3.987,81/kWh for Bukit Raya. This power generation system can reduce CO2 emissions by 22.2 kg/year, with the amount of water produced being 4,757.51 m 3 /year in Bumi Harapan and 7,348.29 m3 /year in Bukit Raya, adjusting to the characteristics of the drilling wells based on PVsyst simulation results.
