Abstract

Abstract: The Pico-hydro power generation is a power plant with a scale below 5 kW. This type of power generation is suitable for areas with streams or rivers with low water levels. One area that has natural conditions like this is the Javan Langur Centre (JLC), a rehabilitation facility for one of the endangered primate species, the langur. To support the operation of JLC, a pico-hydro power plant has been built, which has a capacity of 300 watts. However, due to the water discharge is quite low, the efficiency of the generator is less than 10%, of which, the total output power from the pico-hydro generator is about 27, 3 watts. While the electrical energy requirements in JLC is around 50 watts for lighting. To meet the shortage of electricity supply, it is necessary to increase the power generated by the existing pico-hydro power plant, i.e. by applying a cascade system. This system utilizes water from the existing pico-hydro power plant drainage channel as the intake flow for the new pico-hydro power plant. This system also utilizes differences in elevation or water level to make the terraces. With the application of the cascade pico-hydro system, the electrical power requirements at JLC can be met.
