mikrohidro, hydro flutter, free leading edge cantilevered rigid plateAbstrak
Menurunnya cadangan minyak dunia menjadi krisis global untuk beberapa dasawarsa ke depan. Pencarian alternatif energi terbaharui menjadi topik urgen tren penelitian saat ini. Indonesia memiliki keberlimpahan ketersediaan energi berupa potensi pengembangan mikrohidro. Penelitian ini merupakan penelitian pengembangan teknologi inovatif baru dalam teknologi mikrohidro berupa teknik pengkonversian energi aliran air menjadi energi listrik menggunakan teknologi hidro flutter. Dalam penelitian ini dilakukan pengembangan alat baru pengkonversian energi dari aliran air menjadi energi listrik. Sebuah purwarupa dibangun yang bisa pengekstrak energi dari aliran air di kali menjadi energi mekanik yang siap di konversi menjadi energi listrik menggunakan prinsip hydro flutter dari sebuah flexibly mounted free leading edge cantilevered rigid plate. Keunggulan dari konsep baru yang ditawarkan adalah kesederhanaan dari desain dan kemampuan untuk membersihkan sistem sendiri sehingga mengurangi biaya pemeliharaan.
