Abstract
Indonesia merupakan negara dengan konsumsi energi terbesar di Kawasan Asia Tenggara, yaitu sebesar 213.4 miliar kWh pertahun. Konsumsi energi final tersebut saat ini didominasi oleh batu bara, minyak, dan gas dengan persentase sebesar 70.48%. Berdasarkan Peraturan Pemerintah nomor 79 Tahun 2014 tentang Kebijakan Energi Nasional, Indonesia memiliki target untuk menggunakan bauran energi baru dan terbarukan sebesar 23% pada tahun 2025. Salah satu sumber energi yang menjadi bagian dari target tersebut adalah sumber energi angin dengan potensi sebesar 978 MW. Salah satu metode pemanfaatan energi angin tersebut adalah dengan menggunakan turbin angin. Indonesia memiliki kecepatan angin sebesar 3-7 m/s, jenis turbin yang cocok untuk kondisi tersebut adalah tipe Vertical Axis Wind Turbine (VAWT). Pada penelitian ini digunakan turbin angin Savonius dengan dua sudu yang memiliki diameter turbin (D) sebesar 167,1 mm, diameter end plate (Do) sebesar 320 mm, tinggi (H) sebesar 298 mm dan diameter poros (b) sebesar 19 mm. Penelitian ini dilakukan dengan variasi diameter silinder pengganggu terhadap diameter sudu turbin (d/D) sebesar 0,1; 0,2; 0,4; 0,5; 0,6; 0,7; 0,8; 0,9; dan 1,0 dan letak silinder pengganggu terhadap returning blade (S/D) sebesar 2,6 serta variasi Reynolds Number sebesar 9,7 × 10^4 dan 13,6 × 10^4. Alat ukur yang digunakan adalah anemometer, torque meter, tachometer, dan brake dynamometer. Hasil yang didapatkan dari penelitian adalah bahwa dibandingkan dengan turbin angin Savonius tanpa silinder pengganggu, turbin angin Savonius dengan silinder pengganggu di depan returning blade di posisi S/D = 2,6 paling efektif meningkatkan performa turbin angin Savonius dengan d/D = 0,6 pada Re = 97 x 10^4. Hal ini dibuktikan dengan meningkatnya meningkatnya Coefficient of power maksimum sebesar 32,57%, dan meningkatnya Coefficient of Moment maksimum sebesar 14,25%, serta meningkatkan kemampuan self-starting turbin angin Savonius di semua posisi sudu turbin dibandingkan dengan turbin angin Savonius tanpa pengganggu.

Indonesia currently sits as Southeast Asia’s largest energy consumption with 213.4 billion kWh energy bill per year. The final energy consumption is dominated by coal, oil, and gas with a percentage of 70.48% from overall consumption. Based on Government Regulation number 79 that was issued on 2014 concerning the national energy policy, Indonesia is currently under ambitious goal to reach 23% mixture of renewable energy from its national energy mix by 2025 with wind energy serves as one of the options with potential of 978 MW. One of the most popular method of harvesting wind energy is by altering its kinetic energy through wind turbine. Since Indonesia has typical wind speed ranging from 3 to 7 m/s, vertical axis wind turbine is proven to be the most suitable for this condition. This research used Savonius wind turbine with turbine diameter (D) of 167.1 mm, end plate (Do) diameter of 320 mm, height (H) of 298 mm and shaft diameter (b) of 19 mm. The research conducted with a variation of the diameter of circular cylinder (d/D) of 0.1; 0.2; 0.4; 0.5; 0.6; 0.7; 0.8; 0.9; and 1.0. The circular cylinder will put be against the returning blade with S/D configuration of 2,6 and Reynolds number variation of 9.7 × 10^4 and 13.6 × 10^4. Measurements were performed using anemometer, torquemeter, tachometer, and brake dynamometer. The results obtained from the study were then compared to Savonius wind turbines without circular cylinders which shows that Savonius wind turbines with circular cylinders in front of the returning blade in the position of S / D = 2.6 most effectively improve the performance of Savonius wind turbines with d / D = 0.6 at Re = 97 x 10^4. This statement is proven by the increase in the maximum Coefficient of power by 32.57%, and the increase in the maximum Coefficient of Moment by 14.25%, as well as the improvement self-starting ability of Savonius wind turbines in all turbine blade positions compared with Savonius wind turbines without a circular cylinder.
