STUDI DESTILASI AIR LAUT TENAGA SURYA MENGGUNAKAN BASIN BERTINGKAT BANYAK UNTUK MENGHASILKAN AIR TAWAR DAN GARAM

Abstract

Water and salt are something that must exist in human life in everyday life. These needs can’t be fulfilled by some people in Indonesia who are in the coast. One of the efforts to meet the needs of fresh water is to treat sea water by using solar powered distillation. This study aims to determine the productivity of marine processing equipment into freshwater and salt by utilizing solar energy by making multilevel solar energy distillation device, Stratified absorbent plate, with cross-sectional area (80 cm x 90 cm) x 3 With a volume of 6000 ml and a slope of 30 ° cover glass, Solar heat can heats the absorbent plate and sea water, so the sea water evaporates and is condensed naturally. From research conducted with 6 liters of sea water used in the test obtained 176 grams of salt for 5 days and 3662 ml of fresh water with an average intensity of 566.332 W / m². 

Keywords: Solar Energy, Sea water, Distillation, Fresh Water and Salt.
