Abstract

Telah dilakukan studi eksperimental untuk mengetahui pengaruh Mekanisme Active Pitch pada Turbin Hidrokinetik Tipe Darrieus terhadap efisiensi turbin. Eksperimen dilakukan di Umbulan, Pasuruan. Variasi kecepatan yang digunakan untuk eksperimen adalah 0.674 m/s, 0.806 m/s, 0.944 m/s dengan menggunakan 3 variasi jumlah foil, 3,6 dan 9 foil . Hasil yang diperoleh adalah pengukuran nilai rerata Torsi maksimum mekanisme 3 foil pada kecepatan 0.944 m/s sudut azimuth 30˚ sebesar 5.36 Nm, sedangkan rerata RPM maksimum pada kecepatan 0.944 m/s sebesar 21.1 Rpm.sedangkan 6 foil hasil pengukuran nilai rerata Torsi maksimum pada kecepatan 0.944 m/s sudut azimuth 30˚ sebesar 5.4 Nm, sedangkan rerata RPM maksimum pada kecepatan 0.944 m/s sebesar 12.5 Rpm. Dan 9 foil menghasilkan pengukuran nilai rerata Torsi maksimum pada kecepatan 0.944 m/s sudut azimuth 30˚ sebesar 5.45 Nm, sedangkan rerata RPM maksimum pada kecepatan 0.944 m/s sebesar 10.9 Rpm. Data hasil pengukuran tersebut dapat disimpulkan bahwa variasi 3 foil memiliki efisiensi turbin terbaik dengan nilai 91.6 % pada kecepatan arus 0.994 m/s ======================================================================================================== Experimental studies have been conducted to determine the effect on the mechanism of Active Pitch Type hidrokinetik Darrieus turbine for turbine efficiency. Experiments conducted in Umbulan, Pasuruan. Variations in the speed used for the experiment is 0674 m / s, 0806 m / s, 0944 m / s with 3 variations in the amount of foil, 3.6 and 9 foil. The results obtained are the mean value of maximum torque measurement mechanism 3 foil at a speed of 0944 m / s azimuth angle of 30˚ at 5:36 Nm, while average maximum RPM at a speed of 0944 m / s at 21.1 Rpm.sedangkan 6 foil measurement results at a mean value of maximum torque speed of 0944 m / s 30˚ azimuth angle of 5.4 Nm, while average maximum RPM at a speed of 0944 m / s at 12.5 rpm. 9 foil and produces measurement mean value of maximum torque at a speed of 0944 m / s azimuth angle of 30˚ at 5:45 Nm, while average maximum RPM at a speed of 0944 m / s at 10.9 rpm. The measurement data can be concluded that the three variations foil turbine efficiency best with 91.6% in the value of the flow velocity 0994 m / s
