STUDI EKSPERIMENTAL PENGOLAHAN AIR LAUT MENJADI AIR TAWAR DAN GARAM DENGAN DESTILASI SURYA MENGGUNAKAN COVER DUA KEMIRINGAN

Abstract

Salt and plain water are important needs for human body. In some places of Indonesia, the Government still cannot fullfill the needs of salt and plain water. To cover the national needs, the government still import the salt. This is not common for archipelago country like Indonesia which has a wide sea and the second longest seashore in the world. One way to produce salt and plain water is to use the solar energy. Indonesia is rich of solar energy sine Indonesia is a tropic country. Actually, solar energy is a potential energy resource and free. The purpose of this experiment is to test the prototype of low energy seawater tool of processing in producing salt and plain water. The tools to separate the salt and plain water is using solar energy and is a kind of destilation tool which implemented evaporating sytem. Salt and plain water in seawater are separated by boiling the seawater in solar collector, which evapotares the steam and to cause salt crystal by using solar energy. The result of the experiment shows that 28 L seawater produces 2600 g salt and 3,65 plain water each day.
