Abstract

Populasi penduduk di Indonesia menduduki peringkat ke-4 di dunia dan terus meningkat setiap tahunnya, hal ini berdampak juga kepada kebutuhan energi listrik yang meningkat setiap tahunnya. Namun, dari seluruh energi listrik yang di produksi di Indonesia sebagian besar masih menggunakan energi yang tidak dapat diperbaharui. Penggunaan energi yang tidak dapat diperbaharui memiliki dampak buruk terdahap lingkungan sehingga solusinya menggunakan energi terbarukan, salah satunya energi angin. Salah satu pemanfaatan energi angin adalah menggunakan turbin angin. Turbin angin dapat mengkonversi energi angin menjadi listrik.
Pada penelitian ini menggunakan turbin angin tipe Vertical Axis Wind Turbine (VAWT) jenis Savonius yang memiliki sudu dengan 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; 0,3; 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 1,6. Serta variasi ReynoldsNumber sebesar Re = 97x104 dan 13,6x104. Alat ukur yang digunakan adalah anemometer, torque meter, tachometer, dan brake dynamometer.
Setelah dilakukan penelitian didapatkan hasil bahwa penambahan silinder pengganggu didepan returning blade efektif meningkatkan performa turbin angina Savonius. Ukuran diameter d/D = 0,5 pada Re = 9,7x104 adalah yang paling efektif dalam meningkatkan performa turbin angin Savonius. Hal ini dibuktikan dengan meningkatnya nilai coefficient of power maksimum sebesar 44,74%, coefficient of moment maksimum sebesar 32,04% dan meningkatkan kemampuan self-starting turbin angin Savonius di semua posisi sudut dibandingkan dengan turbin angin Savonius tanpa pengganggu.

Indonesia's population is ranked 4th in the world and continues to increase every year, and it also affects the needs of electrical energy in Indonesia. However, from all the electrical energy produced in Indonesia is largely still using unrenewable energy. The use of unrenewable energy has a bad impact on the environment, so the solution is to use renewable energy such as wind energy. One of wind energy utilization is using wind turbine. Wind turbines can convert wind energy into electricity.
In the study, the type of Savonius Vertical Axis Wind Turbine (VAWT) has a turbine diameter (D) of 167.1 mm. The end plate diameter (Do) is 320 mm, height (H) of 298 mm and the diameter of the shaft (b) by 19 mm. This research was conducted with variation of circular cylinder diameter against the turbine's blade diameter (d/D) of 0.1; 0.2; 0.3; 0.4; 0.5; 0.6; 0.7; 0.8; 0.9; and 1.0. And the location of the circular cylinder against the returning blade (S/D) of 1.6. As well as a variation of Reynolds Number of Re = 97x104 and 13,6x104. The measuring instruments used are anemometer, torque meter, tachometer, and brake dynamometer.
After research was obtained the results that the addition of circular cylinder in front of returning blade effectively increased the performance of the Savonius wind turbine. The size diameter d/D = 0.5 at Re = 9, 7x104 was the most effective on improving the performance of the Savonius wind turbine. This is evidenced by the increase of the maximum coefficient of power value of 44.74%, coefficient of the maximum moment by 32.04% and increase the self-starting capability of Savonius wind turbine in all angular positions compared to the wind turbine Savonius without circular cylinder .
