KAJI EKSPERIMENTAL DESTILASI SURYA DENGAN CERMIN PEMANTUL UNTUK MENGOLAH AIR LAUT MENJADI GARAM

Abstract

Water and salt are essential human needs in life. These needs can’t be fulfilled by the people in some areas in Indonesia which is in the coastal area. One of the efforts to supply water is to utilize the distillation of solar power, the utilization of solar power for the distillation or distillation of sea water into clean water and salt is a form of alternative energy utilization. This research aims To develop productivity of marine processing equipment into freshwater and salt, to get the productivity of the sea water processing equipment into freshwater and salt by using solar energy by making the device of solar energy distillation of flat absorbent plate, cover of one slope cover, And with the addition of a reflective mirror. Then, sea water is placed into a 0.9 cm tall basin with a volume of 12000 ml, 1.1 cm with a volume of 14000 ml, and 1.3 ml with a volume of 16000 ml of sea water with a cross-sectional area of 80 cm x 180 cm and a slope Cover glass 30 °. This research was conducted on 12 April 2017 until 27 April 2017 in open field beside Chemical Laboratory of Bung Hatta University Faculty of Industrial Technology University of Bung Hatta Padang. From the research, the result of condensate with 12000 ml sea water produces salt as much as 471,8 gr for 5,5 days, fresh water yielded 10946 ml with average intensity 437,91 W / m², 14000 ml produce salt as much as 635, 72 grams for 4.5 days, fresh water produced 12315 ml with an average intensity of 619.57 W / m², and 16000 ml yielding salt 718.34 gr for 5 days, fresh water produced 14012ml with an average intensity of 492 , 55 W / m².
