Abstract
Indonesia merupakan negara yang memiliki sumber daya alam yang melimpah, dimana sumber daya alam tersebut dapat dijadikan sumber energi untuk keberlangsungan hidup. Seiring berjalannya waktu, ketersediaan sumber daya alam tersebut semakin menipis. Untuk mengatasi ketergantungan terhadap energi fosil, maka perlu pengembangan untuk mendapatkan sumber energi baru terbarukan. Salah satu energi terbarukan yang belum banyak dimanfaatkan secara optimal dan memiliki potensi besar untuk dikembangkan adalah energi angin. Energi angin dapat digunakan untuk memutar poros turbin angin yang kemudian putaran tersebut ditransmisikan pada generator listrik. Dengan meletakkan silinder pengganggu di depan returning blade turbin angin tipe Savonius, maka performa turbin angin dapat ditingkatkan. Hal tersebut merupakan tujuan dari penelitian ini. Untuk meningkatkan performa turbin angin Savonius yang memiliki diameter (D) = 60 mm dan tinggi (H) = 80 mm, digunakan silinder yang memiliki diameter (d) = 45 mm yang diletakkan di depan returning blade turbin. Pengganggu tersebut diletakkan dengan variasi jarak 1,5 ≤ S/D ≤ 2,4. Penelitian dilakukan di dalam open circuit wind tunnel, dengan dimensi tes uji; panjang 457 mm, lebar 304 mm dan tinggi 304 mm. Pada kecepatan angin masuk sebesar 8,77 m/s; 10,97 m/s; 13,16 m/s

Indonesia is one of the country that has a lot of natural resources, which could be use as energy resources for sustaining life. Along with time, natural resources availability is decreasing. To overcome the dependence towards fossils based energy, research is needed to get a new renewable energy. One of the alternative energy that has not been used optimally and has a high potential to be developed is wind energy. Wind energy could be used to drive the wind turbine shaft, then the shaft's rotation is transmitted to an electric generator. By placing the disturbance cylinder in front of the returning blade of Savonius turbine, the Savonius wind turbine performance is expected to be increased. It is the objective of this research. In order to increasing the performance of Savonius wind turbine having a diameter (D) of 60 mm and height (H) of 80 mm, a cylinder having a diameter (d) of 45 mm is used as a disturbance located in front of returning blade of turbine. This disturbance is located in various spacing positions of 1,5 ≤ S/D ≤ 2,4. The experiments are carried out in a subsonic open circuit wind tunnel. This facility has a 457 mm long, with test section 304 mm x 304 mm. The free stream velocity of wind tunnel could be adjusted to 8,77 m/s; 10,97 m/s; 13,16 m/s
