Abstract

Di Indonesia pembangkit listrik didominasi dengan bahan bakar minyak dan gas bumi yang merupakan sumber daya alam yang tidak dapat diperbaharui. Oleh karena itu perlu dikembangkan energi alternatif yang mudah didapatkan, misalnya adalah angin. Potensi penggunaan turbin angin adalah di daerah pesisir dimana pada daerah tersebut memiliki energi angin antara 3 – 7 m/s. Pada penelitian ini menggunakan turbin angin tipe bilah bersirip yang termasuk kategori turbin angin poros vertikal. Turbin ini menggunakan sirip yang bisa membuka dan menutup sesuai dengan arah datangnya angin sehingga dapat menurunkan energi drag. Sirip-sirip pada bilah akan terbuka apabila berlawanan dengan arah datangnya angin dan putaran poros sehingga akan menurunkan energi drag, sebaliknya apabila searah dengan arah datangnya angin dan putaran porors sirip-sirip akan menutup sehingga dorongan angin dapat meningkatkan drag dan meningkatkan daya dorong. Penelitian dilakukan dengan instalasi wind tunnel dari Laboratorium Mesin Mesin Fluida Teknik Mesin Universitas Brawijaya Malang. Metode yang digunakan adalah metode penelitian eksperimental nyata (true experimental research). Variabel bebas dalam penelitian ini adalah variasi kecepatan angin sebesar 3, 4, 5, 6, dan 7 m/s serta bilah dengan perbandingan ½, 3/5, 2/3. Variabel terikat dalam penelitian ini yaitu Daya poros, Torsi, dan Efisiensi yang dihasilkan turbin angin tipe bilah bersirip. Sedangkan variabel terkontrol dalam penelitian ini adalah jumlah bilah 3 buah, panjang 25 cm dan jumlah sirip 5 buah serta suhu ruangan 27°C. Dari hasil pengujian dan pengolahan data menunjukkan bahwa variasi lebar pada bilah turbin angin tipe bilah bersirip berpengaruh terhadap unjuk kerja turbin angin tipe bilah bersirip. Pada pengujian ini daya poros, torsi, dan efisiensi tertinggi tercapai pada lebar bilah 6 cm.
