PERANCANGAN TURBIN ANGIN SAVONIUS SUMBU VERTICAL UNTUK LAMPU PENERANGAN RUMAH TANGGA

The design of the vertical axis savonius wind turbine was carried out to obtain alternative energy for household lighting in the village of Tepal. Wind turbines are designed at an average wind speed of 3-5 m / s, wind speeds are obtained from the Sumbawa Besar BMKG data. This wind turbine has the advantages of being able to receive wind from all directions with 4 blade blades, wind turbine blade materials using Aluminum so that it is resistant to rust and extends the life of use, obtained by the turbine power coefficient of 1.18%. The results of the design and calculation are as follows: consisting of 4 blade blades and made of Aluminum with a height of 1800 mm, shaft 15 mm, bearing Ø outside 32 mm, Ø inside 15 mm, the tower is made of steel and uses a generator using 600 rpm
