Studi Eksperimental Perbandingan Produktivitas Air Tawar Solar Still Double Slope Single Basin dan Triple Basin

Abstract

Water is one of the basic necessities in daily life. However, most of the planet is covered by water. Water covering the earth 2.5% of which is classified as fresh water. To overcome this can be done by converting seawater into fresh water through the desalination process. desalination method is to remove salt from seawater to produce clean water, this desalination method utilizes solar heat as the main energy, while adding glass media is given in the middle, and above and the location in the tub is at the bottom of the middle of the top. for this reason, a comparative study of freshwater productivity of conventional double-tilt solar stills and triple basin solar stills was conducted with the aim of knowing the comparison of freshwater productivity and efficiency produced. In this study using 2 variations of testing, namely tool a (Conventional Desalination), and tool b (Desalination 3 tubs) conducted within 24 hours. In the results of the study obtained the best mass of fresh water during the day is tool a which is 1233 g and on tool b which is 629 g. at night the best results obtained are tool b which is 251 g and on tool a which is 109 g, and the efficiency results obtained by tool a which is 29% and efficiency on tool b which is 16%.
