Abstract

Indonesia is a country made up of thousands of islands. Indonesia is located between four tectonic plates, the Indian Ocean Plate, and the Pacific Ocean Plate, the Asian Continental Plate, and the Australian Continental Plate. Geographically, the territory of Indonesia is in the series of Ring of Fire. The Ring of Fire, also called the Circum-Pacific Belt, is a 40,000 km-long chain of volcanoes and seismically active sites spanning the Pacific Ocean. This condition is very potential as well as prone to disasters such as volcanic eruptions, earthquakes, tsunamis, floods, and landslides. The impact of this disaster can make it difficult to access clean water, electricity, and fuel oil networks. Access to electricity is not available because the power grid is cut. The purpose of this research is to be able to provide first aid in terms of electricity so that it can relieve victims of natural disasters or volunteers who work to evacuate victims. The output targeted in this research is a Portable Solar Generator that can be used in an emergency by disaster-affected victims or by volunteers. With a 35-watt load, it could operate for 5 hours 30 minutes and with 55 Watt load it can operate for 3 hours. In terms of recharging time, the charging process using a 50 Wp solar panel takes approximately 7 hours, this is because the charging process is carried out outside the building according to actual conditions.
