Rancang Bangun Pembangkit Listrik Tenaga Air Pico Hydro Menggunakan Turbin Archimedes Screw (Studi Kasus di Desa Sihemun Baru)

Abstract

Indonesia is a country that has a large area and a high population. As a country with diverse geographic conditions and a dispersed population, Indonesia still faces challenges in fulfilling energy for all of its citizens, one of which is Sihemun Baru Village. Sihemun Baru Village is located in Dolok Pardamean District, Simalungun Regency, North Sumatra. Sihemun Village has abundant natural resource potential, one of which is a source of water that flows swiftly throughout the year. So far, the river flow has only been used by the community to flow through the fields as irrigation canals. This study aims to produce a pico hydro power generator using a screw turbine. The river flow that will be utilized in this study has a width of 2.16 cm and a depth of 120 cm. The working principle of this tool is to take advantage of the low flow of river water (does not require dams or ponds). River water flows into the turbine screw and drives the turbine screw so that it rotates the generator through a shaft connected to the clutch. The mechanical energy from the shaft is converted into electrical energy by the generator. Based on the results obtained, by the height of the water head is 100 cm with gear ratio 1:5.83 and water discharge capacity of 18.66 liters/second with 1 blade which can produce 15.21 watts of generator power and 224 RPM with output voltage from the generator is 11.52 volts
