PENGARUH PENYERAPAN RADIASI SURYA PADA MEDIA TIPE KOTAK DAN BERGELOMBANG BERBAHAN DASAR STAINLESS STEEL TERHADAP KEMAMPUAN DESTILASI AIR PAYAU DI PESISIR PANTAI SEBA

Abstract

The use of solar radiation absorber on box and corrugated media can improve the ability or
performance of the brackish water distillation process into freshwater. This process of brackish
water distillation is to separate the excessive salt elements contained in brackish water, by heating
by using solar energy so that evaporation takes place within the distillator and under certain
conditions will experience condensation, so that the hot vapor turns phase into water because it
comes into contact with a cold glass surface. Thus, the water will be obtained clean and not salty
anymore. While salt water will be left in the container destilator because there are elements of
salt in which have a larger density. This study was conducted using real experimental method  (true experimental) on laboratory scale. The test is done at 8:00 until 16:00 with the volume of water in
the distillator as much as 35 liters. The results show that efficiency increases in parabolic over time but
decreases above at 14.00. This happens because the intensity of solar radiation will decrease along with
the sun’s incline to the west, so the heat received by the destilator decreases. The highest efficiency
occurs at 12.00 ie on the absorbent type of box of 16.72% while the absorbent type of wave surges
highest efficiency also occurs at 12:00 at 12.509%, this happens because at this time the sun radiates
suryanya maximum.
