Abstract
Curugmuncar II micro hydro power (MHP) located in Petungkriyono sub district is one of three MHPs installed in Pekalongan district. This study aims to analyze the MHP operation environmental impact. The study used qualitative method, with interviews, observations, and material testing. The data used are primary and secondary data. This research was conducted in Curugmuncar Village, Petungkriyono Subdistrict, Pekalongan Regency, Indonesia. MHP has power capacity of 100 KW with power usage of 50 KW. MHP used by 155 users with load capacity 2 A 220 volt AC. The community more used of lights as the houses and street lighting. The MHP operation had several environmental factors such as: sociology, technically feasible, hydrology, physical and chemical water quality, ergonomics, economically feasible, irrigation, clean water supply, government policy, and others. The supporting factors sustainability of MHP were sociology, irrigation, ergonomics, clean water supply, physical and chemical water quality, hydrology, and government policy. The inhibiting factors of MHP operation were technically feasible, economically feasible, and government policy. The results showed that the MHP environment requires a professional management system to achieve the MHP sustainability

Summary
Energy plays an important role in a country's economy. Renewable energy sources are potential solutions to meet energy needs, especially in rural areas. The use of renewable energy is considered to contribute to reducing the impacts of climate change and environmental degradation [1]. Data from the statistics of Indonesia's EBTKE related to renewable energy and energy conservation (2016) showed that the new renewable energy mix in Indonesia has increased by an average of 0.36% annually. The new renewable energy mix as primary energy source still occupies the lowest position with a percentage of 6.2% compared to 43.0% for petroleum, 28.7% for coal and 22.0% for natural gas by 2015. The achievement of new renewable energy has increased since 6 Last year, In 2010, the renewable energy (RE) achievement of electricity amounted to 48,184,711 barrel of oil equivalent (BOE) and continued to increase until reaching 73,497,500 BOE by 2015
