Rancang Bangun Pembangkit Listrik Tenaga Air Pico Hydro Menggunakan Turbin Turgo pada Aliran Air Terjun Bah-Biak

Abstract

One of the main forms of energy needed for electrical equipment is electrical energy. The potential for hydropower in Indonesia is 75 GW, mostly spread across Sumatra, Sulawesi, Kalimantan and Papua. Bah-Biak Waterfall is a potential for hydropower located in Sidamanik District, Simalungun Regency, North Sumatra, this waterfall has a fairly stable flow. Therefore, this water flow can be used to generate electricity, with output power ranging from tens to thousands of watts, depending on the water flow, head and generating technology. The Bah-Biak waterfall is one of the tourist attractions in Sidamanik, so there are places for residents to sell that are not provided with lighting because they are difficult to reach. Therefore, this research is expected to be able to help residents in lighting their selling places. Hydroelectric power plant pico hydro with the turbine method turgo which is used directly in the waterfall flow aims to utilize the limited energy potential of water so that it can produce electricity by application in the waterfall flow, which can be used to illuminate the area around the waterfall tourist attraction. Based on the test results, distance results were obtained Nozzle 20 cm, the generator rotational speed is 964,4 RPM, the voltage value is 13,8 V and the current generated is 1,21 A. Meanwhile, at a distance Nozzle 60 cm, the generator rotation speed was 876,8 RPM, the voltage value was 13,35 V and the current generated was 0.92 A. The highest power generated by a pico hydro power plant with a turbine turgo with distance Nozzle 20 cm water discharge 23L, namely 19,86 watts
