The Hybrid Photovoltaic Picohydro power plant is an alternative power plant that is being developed, where the power plant consists of two sources of electricity, from solar and hydro energy. Picohydro was designed with a single axis shaft generator with turbine rotors, but both components have the same rotational speed. It’s needed to use reduction gear for the appropriate speed generator specifications used. This research will achieved the picohydro power transmission system. Design gearbox will accordance with specification of generator. The study began with the design of gearbox components and then proceed with the manufacturing process. The design of a components will use FEA software. The results have transmission shaft 8 mm dimensions, with a transmission ratio of 2.5 using bevel gear, Pinion gear maximum stress about 296.7 Mpa, with material S45C obtained a FOS of 1.78.
