Abstract

Indonesia is one of the largest archipelago countries which is rich in seawater, because Indonesia is located in the midst of seawater with thousands of islands. However, this does not guarantee that the livelihood of people living in the coast to get fresh water and salt. Lack of fresh water and salt are major problems for coastal communities. To obtain fresh water they have to buy fresh water. One of the right solutions to overcome this problem is by distillation by utilizing the abundant sea water and then processing it into fresh water and salt. The result of observation indicated the value of the temperature changed every day depending on the amount of intensity of sunlight received. The average environmental temperature obtained from testing for six days ranged 31,08°C - 38,26°C. In this study, the average temperature of the glass was 33,48°C - 47,88°C. The water temperature obtained in this experiment was 32°C - 56,42°C. The result of the study showed that solar power destilators could convert 10 liters of sea water to 5,8 liters of fresh water within a period of six days. When the ambient temperature dropped, the temperature of the glass decreased. This is because the temperature of the glass was directly effected by the temperature of the environment. The water temperature did not directly affect the ambient temperature, because water was a good heat storage. Besides producing fresh water the rest of the sea water distillation also produced 0,190 kg of salt.
