Abstract
Energi angin yang dimiliki Indonesia diidentifikasi memiliki potensi sekitar 978 MW. Pada beberapa wilayah indonesia, telah dilakukan beberapa kali penelitian dan pengukuran potensi energi angin oleh LAPAN dan BMKG. Berdasarkan pengukuran, potensi kecepatan angin pada dataran rata-rata adalah sekitar 3 m/s dan 7 m/s. Potensi energi angin terbesar berada pada wilayah Sidrap dan Jeneponto di Sulawesi Selatan memilki potensi menghasilkan listrik kurang lebih sebesar 200 MW. Saat ini kedua wilayah tersebut telah dibangun Pembangkit Listrik Teanga Angin (PLTA). Selain Sidrap dan Jeneponto, beberapa wilayah yang memiliki potensi antara lain adalah Sukabumi (170 MW), Garut (150 MW), Lebak dan Padeglang (masing-masing 150 MW), dan Lombok (100 MW). Turbin Savonius adalah turbin angin sumbu vertikal (VAWT). Banyak penelitian yang telah dilakukan oleh peneliti terdahulu untuk meningkatkan performa turbin angin Savonius ini. Penelitian ini dilakukan dalam upaya meningkatkan lebih jauh performa turbin angin Savonius dengan penenpatan silinder di samping advancing blade dan di depan returning blade. Turbin angin Savonius yang digunakan memiliki 2 sudu turbin dengan diameter sudu (D) 165.2 mm, tinggi turbin (H) 295 mm dengan dua end plates pada bagian atas dan bawah dengan tebal (t) 1 mm dengan diameter end plates (D0) 320 mm, diameter poros (b) sebesar 19 mm. Pada penelitian ini silinder penggangu berbentuk silinder dengan diameter 88,8 sehingga diperoleh rasio dengan diameter sudu d/D = 0.5 dengan variasi kecepatan angin 4, 5, 6, dan 7 m/s dengan dua konfigurasi yaitu pertama penempatan silinder di samping advancing blade pada jarak S/D = 1,82 dan kedua penempatan silinder di samping advancing blade pada jarak S/D = 1,82 dan silinder di depan returning blade pada jarak Y/D = 1,82.Penelitian dilakukan menggunakan sumber angin dari axial fan yang ditambahkan honeycomb pada bagian depannya dengan tujuan agar aliran yang mengalir adalah aliran uniform. Pengaturan kecepatan axial fan, diatur dengan menggunakan voltage regulator kemudian kecepatan aliran udara diukur menggunakan anemometer, pengukuran kecepatan turbin menggunakan tachometer, dan pengukuran torsi statis dan dimanis menggunakan torquemeter dan brake dynamometer. Hasil penelitian yang didapatkan adalah peletakan silinder penggangu di samping advancing blade dengan jarak Y/D = 1,82 efektif pada kecepatan angin 4 m/s dan 5 m/s, dimana pengingkatan tertinggi terjadi pada kecepatan 5 m/s sebesar 3,5% terhadap nilai coefficient of power konvensional dan 2,24% terhadap nilai coefficient of moment konvensional. Kemudian peletakan silinder di samping advancing blade dengan jarak Y/D = 1,82 dan di depan returning blade dengan jarak S/D = 1,82 efektif pada seluruh kecepatan, dimana peningkatan tertinggi terjadi pada kecepatan 5 m/s sebesar 31,75% terhadap nilai coefficient of power konvensional dan pada kecepatan 6 m/s sebesar 11,2% terhadap nilai coefficient of moment konvensional. Peletakan silinder di samping advancing blade dengan jarak Y/D = 1,82 dan di depan returning blade dengan jarak S/D = 1,82 memperbaiki kemampuan self starting tetapi masih belum mampu memberikan kemampuan self starting.

Indonesia's wind energy is identified as having a potential of around 978 MW. In several regions of Indonesia, research and measurement of wind energy potential has been carried out several times by LAPAN and BMKG. Based on the measurements, the potential wind speed on the average plain is about 3 m/s and 7 m/s. The greatest potential for wind energy is in the Sidrap and Jeneponto areas in South Sulawesi, which have the potential to generate electricity of approximately 200 MW. Currently, the two areas have built the Teanga Angin Power Plant (PLTA). Besides Sidrap and Jeneponto, several areas that have potential include Sukabumi (170 MW), Garut (150 MW), Lebak and Padeglang (150 MW each), and Lombok (100 MW). The Savonius turbine is a vertical axis wind turbine (VAWT). Many studies have been carried out by previous researchers to improve the performance of this Savonius wind turbine. This research was conducted in an effort to further improve the performance of the Savonius wind turbine with adding cylindrical Disturbant on the side of advancing blade and in front of returning blade. The Savonius wind turbine used has 2 turbine blades with a blade diameter (D) of 165.2 mm, a turbine height (H) of 295 mm with two end plates on the top and bottom with a thickness (t) of 1 mm and a diameter of end plates (D0) of 320 mm. , the diameter of the shaft (b) is 19 mm. In this study the intruder cylinder is cylindrical with a diameter of 88.8 so that the ratio of the blade diameter d/D = 0.5 with variations in wind speed 4, 5, 6, and 7 m/s with two configurations is obtained, namely the first placement of the cylinder next to the advancing blade at a distance of S. /D = 1.82 and both cylinders are placed next to the advancing blade at a distance of S/D = 1.82 and the cylinder in front of the returning blade at a distance of Y/D = 1.82.The research was conducted using a wind source from an axial fan with honeycomb added to the front with the aim that the flow is uniform. Axial fan speed regulation, regulated using a voltage regulator then air flow velocity was measured using an anemometer, turbine speed measurement using a tachometer, and static and sweet torque measurements using a torquemeter and brake dynamometer. The results obtained are the placement of the disrupting cylinder next to the advancing blade with a distance of Y/D = 1.82 effective at wind speeds of 4 m/s and 5 m/s, where the highest increase occurs at a speed of 5 m/s at 3.5% to the value of the conventional coefficient of power and 2.24% to the value of the conventional coefficient of moment. Then the placement of the cylinder beside the advancing blade with a distance of Y/D = 1.82 and in front of the returning blade with a distance of S/D = 1.82 is effective at all speeds, where the highest increase occurs at a speed of 5 m/s at 31.75% against the value of the conventional coefficient of power and at a speed of 6 m/s of 11.2% against the value of the conventional coefficient of moment. Placing the cylinder beside the advancing blade with a distance of Y/D = 1.82 and in front of the returning blade with a distance of S/D = 1.82 improves the self starting ability but is still unable to provide self starting capability.
