Utilization of Small Wind Turbines as Source Alternative Electrical Energy for Lighting in the Banyak Island Tourism Area, Aceh Singkil, Indonesia

Abstract

Currently, the development of renewable energy sources for power generation is very prominent. This is done to reduce the availability of fossil energy sources. In addition, the burning of fossil energy sources will have an impact on the environment and the production of gas emissions. Based on the availability of sources and small environmental impact, wind power plants have great energy potential to be explored. Balai island Banyak island in Aceh Singkil-Indonesia has been developed as a tourist destination that has great potential to increase regional foreign exchange. The increasing number of visitors in the Balai Island area will certainly have an impact on increasing the need for electrical energy. The electricity consumption in this area is only supplied by using diesel power plants. Renewable energy based on wind power plants needs to be developed as an alternative to preserve Balai Island from environmental impacts due to the use of fossil-based electricity. Therefore, a study of the potential resources of wind power plants must be carried out to implement wind power plants on Balai Island. The purpose of this study was to determine the potential of wind energy and determine the appropriate type of wind turbine in the Water Front Tourism Area of Balai island Banyak Island as an alternative lighting. The method used in this research is quantitative type with data processing and descriptive approach. The data obtained were analyzed using analytical methods to calculate the potential of wind energy and its conversion into electrical energy. After analyzing the wind speed data in 2020 in the Balai island tourist area with the weibull distribution equation, the parameters k = 2.935758902 and c = 8.921518. Through capacity factor analysis, it is known that small-scale wind turbines produce energy of 115,154 kWh/year per turbine with an electrical energy cost of Rp. 507,S26/kWh and the total annual net income (net income per year) is Rp. 123,602,608.34.
