PEMANFAATAN ENERGI TERBARUKAN PADA PENERANGAN JALAN UMUM UNIVERSITAS MUHAMMADIYAH YOGYAKARTA DENGAN LAMPU LED BERTENAGA SOLAR CELL
Abstract
The increasing use of electricity has caused an energy crisis which is a fundamental problem in Indonesia. The sun is one of the renewable energy that is used as a power plant. Sunlight is converted into electricity directly needed by a device called a solar cell. One application is used for energy sources for street lights in public street lighting. Planning and designing solar cell-based PJU aims to apply solar cell as a more effective and efficient renewable energy. This research was conducted by looking for solar cell related literature, data collection, market surveys, selection, and design in the Muhammadiyah University of Yogyakarta campus environment. The solar cell PJU at UMY was designed with 30 Watt lamp loads, 8 m pole height, ± 7 m road width, and the distance of each pole 22.45m. The tools consist of polycrystalline type solar cell, VRLA battery, 10 A SSC, and 30 Watt HPL LED light. The working principle of this solar cell PJU by converting solar cells into energy, the energy is used to charge the battery that will flow to the SSC. When the battery is full, the SSC will disconnect the voltage entering the battery. It is this SCC that has an important role to turn ON and OFF the lights with the program.
