Abstract
Energi Angin merupakan salah satu energi alternatif yang sangat menjanjikan jika dapat dimanfaatkan dengan baik. Pemanfaatan energi angin untuk diubah menjadi energi listrik dapat menggunakan turbin angin dan generator. Turbin angin tipe Savonius merupakan rotor angin dengan sumbu tegak (vertical) yang dikembangkan oleh Singuard J. Savonius pada tahun 1920. Salah satu kelemahan yang dimiliki turbin Savonius yaitu efisiensi yang rendah. Torsi dan putaran yang dihasilkan oleh turbin Savonius disebabkan oleh adanya perbedaan gaya drag pada advancing blade dan returning blade. Salah satu cara untuk meningkatkan performa turbin Savonius dapat dilakukan dengan pemberian plat pengganggu didepan returning blade. Untuk meningkatkan performa turbin Savonius dengan diameter D sebesar 60 mm dan tinggi h sebesar 80 mm, sebuah plat dengan tebal 3 mm dan lebar 84,9 mm digunakan sebagai pengganggu yang diletakkan didepan returning blade turbin. Pengganggu tersebut diletakkan dengan pada sudut 0o< ɑ < 90o . Penelitian ini dilakukan pada subsonic open circuit wind tunnel. Alat ini memiliki panjang 2980 mm, dengan test section 304 mm x 304 mm. Kecepatan free stream pada wind tunnel diatur sebesar 8,752 m/s, 10,94 m/s, 13,128 m/s, sesuai dengan Reynolds number Re = 6.0 x 104 , 7.5 x 104 , 9.0 x 104

Wind energy is one of the promising alternative energy when it could be optimally used. Taking advantage of wind energy conversion to get electric power is by using a wind turbine and elecetric generator. Savonius type wind turbine is a vertical wind rotor which is developed by Singuard Savonius in 1920. The weakness of Savonius turbine is low efficiency. Torsion and rotation produced by the turbine is caused by the drag force difference between its advancing blade and returning blade. One of the method to increase the performance of Savonius turbine is by placing a disturbance plate in front of the returning blade. In order to increasing the performance of Savonius wind turbine having a diameter D of 60 mm and height h of 80 mm, a plate having a width of 3 mm and a height of 84,9 mm is used as a disturbance located in front of returning blade of turbine. This disturbance is located in various angle of 0o< ɑ < 90o . The experiments were carried out in a subsonic open circuit wind tunnel. This facility has a 2980 mm long, with test section 304 mm x 304 mm. The free stream velocity of wind tunnel could be adjusted to 8,752 m/s, 10,94 m/s, 13,128 m/s, corresponding respectively to Reynolds number Re = 6.0 x 104 , 7.5 x 104 , 9.0 x 104
