Abstract
Energi angin merupakan energi yang berlimpah dan terbarukan yang dapat dimanfaatkan untuk menggerakkan peralatan mekanis dan menghasilkan listrik. Peralatan mekanis yang dimaksud berupa turbin angin. Dengan kecepatan rata-rata angin sebesar 2m/s sampai 6m/s menunjukkan bahwa kecepatan angin di Indonesia terbilang cukup rendah. Berdasarkan hal tersebut penelitian ini bertujuan membuat rancang bangun turbin angin Savonius tipe horizontal axis pada kecepatan angin rendah dan dapat mengukur keluaran turbin untuk mendapatkan daya keluaran serta efisiensi yang dihasilkan turbin. Metode yang digunakan dalam penelitian ini adalah metode eksperimen. Rancang bangun turbin dibuat menggunakan clear pvc 0,3mm sebagai bahan dasar sudu turbin, sudu turbin berjumlah 3 sudu tipe-u berbentuk heliks dengan dimensi panjang 93cm, lebar 16cm dan radius 8cm. Dan menggunakan aluminium profile 20mm × 20mm sebagai bahan dasar rangka turbin, rangka turbin berdimensi panjang 100cm, lebar 30cm dan tinggi 35cm. Pengambilan data dilakukan 10 kali pengulangan pada setiap variasi kecepatan angin (1m/s sampai 10m/s). Hasil penelitian yang didapat menunjukkan peningkatan daya keluaran tertinggi terjadi pada kecepatan angin 6m/s dengan daya sebesar 0,46Watt meningkat 0,13Watt dari variasi kecepatan angin sebelumnya. Dan menghasilkan putaran poros rata-rata 132,28rpm, daya keluaran rata-rata 0,27 Watt, dan efisiensi rata-rata 7,10% pada variasi kecepatan angin 2m/s sampai 6m/s. **************************************** Wind energy is an abundant and renewable energy that can be used to drive mechanical equipment and generate electricity. The mechanical equipment in question is a wind turbine. With an average wind speed of 2m/s to 6m/s, it shows that the wind speed in Indonesia is quite low. Based on this, this study aims to design a horizontal axis Savonius wind turbine at low wind speeds and can measure turbine output to obtain the output power and efficiency of the turbine. The method used in this research is the experimental method. The turbine design is made using 0.3mm clear PVC as the basic material for the turbine blades, the turbine blades consist of 3 helical U-type blades with dimensions of 93cm long, 16cm wide and 8cm radius. And using an aluminum profile of 20mm × 20mm as the basic material for the turbine frame, the turbine frame has dimensions of 100cm long, 30cm wide and 35cm high. Data collection was carried out 10 times for each variation of wind speed (1m/s to 10m/s). The results showed that the highest increase in output power occurred at a wind speed of 6m/s with a power of 0.46Watt, an increase of 0.13Watt from the previous wind speed variation. And produces an average shaft rotation of 132.28rpm, an average output power of 0.27Watt, and an average efficiency of 7.10% at wind speed variations of 2m/s to 6m/s.
