RANCANG BANGUN ALAT DESTILASI SURYA AIR KOTOR DENGAN PENAMBAHAN SOLAR HEATER

Abstract

Water is a very important human need in life. these needs can not be met by the public in some areas in Indonesia are located area of coastal waters of the island, and some areas lack of clean water is a major problem. One of the efforts for the provision of water is to use solar distillation, solar energy utilization for distillation or refining dirty water into clean water is a form of alternative energy replaces energy produced by oil. This research aims to develop a processing tool productivity dirty water into clean water, to obtain productivity of processor dirty water into clean water using solar energy by making solar energy distillation equipment flat absorber plate, cover glass of the slope and penambhan solar heaters. The working principle of this distillation apparatus, namely seawater was added collectors flat-plate solar distillation 1,500 ml and openings out of the water heater to the solar collector solar distillation of 10 ml / min. collector area 80 cm x 50 cm and 30 ° tilt glass cover. Solar radiation into the collector and heat-absorbing plate and sewage. So the dirty water and steam evaporates and is attached dikaca cover due to temperature differences between interior basin with outside collectors condensation. Results condensation drain and clean water is collected and obtained. Collectors heated continuously until the dirty water in the collector depleted and can produce clean water. To speed up the heating plate absorber then added solar heaters. This research was conducted from november 2016 to December 2016 in an open field beside the Material Laboratory of Mechanical Engineering University Faculty of Industrial Technology Bung Hatta Bung Hatta University in Padang. From the study of solar distillation equipment by using solar heater condensate results obtained 2,051 ml. While not wearing a solar heater with condensate amounted to 1.483 ml. with an average intensity of 672.5 W / m². The time required for one day for 9 hours from 08.00 sampa 17:00 pm.
