Abstract

Energy is very much needed for human survival, for example energy from fossil fuels is still the raw material to meet energy needs in Indonesia. Meanwhile, the use of new renewable energy is still low. The potential for utilizing wind energy in Indonesia as a raw material for new renewable energy needs to be optimized. One of the uses of wind energy is the Savonius wind turbine as an electricity generator. The design is quite simple, making this turbine able to operate at low wind speeds. This is in accordance with wind conditions in Indonesia, which are on average low. This research aims to create a turbine with maximum efficiency. The Savonius wind turbine is made from hollow square iron and zinc plate. The blades are made with varying heights of 0.5 m, 0.6 m and 0.7 m with 4 blades each. This research is using experimental method. Retrieval of data in the form of wind speed, air temperature, shaft rotation, torque and electrical voltage. This research data analysis uses quantitative descriptive analysis. The research results stated that the highest efficiency was 18.04% from a blade height variation of 0.5 m at a wind speed of 5.3 m/s. and the lowest efficiency was 12.25% from a blade height variation of 0.7 m at a wind speed of 3.8 m/s. The area of the wind catchment affects the efficiency value obtained.
