Abstract
ABSTRACT The increase in electricity consumption in one side and the depletion of fossil fuel sources in the ot her side have triggered Indonesia to support any development of renewable-based electricity generation, includi ng microhydro-based power plant. The objective of this research was to investigate technical and cost performance of microhydro power plant. Observation was conducted on four microhydro power plants located in Bogorejo village, Sub district of Gedong Tataan, Pesawaran District, Lampung Province. The plants were developed and self-managed by the community. P arameters to be measured or recorded included head of water, voltage and electrical current produced f rom the generator, number of family serviced by the plant, and electricity price that community should pay. Res ults showed that power output of the plants was ran ging from 314 to 1805 W with 2 to 20 families were servi ced for each unit. The research revealed that outpu t power was related to the combination factor of head , the diameter of base penstock pipe, and inverse o f generator’s pulley size. The output power was also linearly related to installation cost. With an inst allation cost of 8 to 40 million rupiahs per unit, the elect ric energy price was in the window of 633 to 973 ru piahs per kWh. It was concluded that Rohman’s microhydro, with power output of 1805 W and energy price of Rp.633/kWh, was the best compared to the others. Keywords: microhydro, performance, energy price, power ABSTRAK Peningkatan konsumsi listrik di satu sisi dan menip isnya sumber bahan bakar fosil di sisi lain telah memicu Indonesia untuk mendukung pengembangan pemba ngkit listrik berbasis energi terbarukan, termasuk pembangkit listrik berbasis mikrohidro. Tu juan dari penelitian ini adalah untuk menyelidiki kinerja teknis dan biaya pembangkit listrik tenaga mikrohidro. Pengamatan dilakukan pada empat pembangkit listrik mikrohidro yang terletak di Desa Bogorejo, Kecamatan Gedong Tataan, Kabupaten Pesawaran, Provinsi Lampung. Pembangkit listrik ini dikembangkan dan dikelola sendiri oleh masyarakat. Parameter yang akan diukur dan diamati meliputi tin ggi air jatuh (head), tegangan dan arus listrik yan g dihasilkan dari generator, jumlah keluarga yang dil ayani oleh pembangkit, dan harga listrik yang harus dibayar oleh masyarakat. Hasil penelitian menunjukk an bahwa output daya pembangkit adalah berkisar 314-1805 W dengan 2 sampai 20 keluarga yang dilayan i untuk setiap unit. Penelitian ini juga menunjukkan bahwa daya output berkaitan dengan komb inasi faktor tinggi head, diameter pangkal pipa penstock, dan invers dari ukuran pulley generator. Daya output juga berhubungan secara linier terhadap biaya instalasi. Dengan biaya instalasi 8-40 juta r upiah per unit, harga energi listrik berada di kisa ran 633- 973 rupiah per kWh. Disimpulkan bahwa mikrohidro mi lik Rohman, dengan daya output 1805 W dan harga energi Rp.633/kWh, adalah yang terbaik diband ingkan dengan yang lain. Kata Kunci: mikrohidro, kinerja, harga energi, daya.
