ABSTRACT

The fastest water access in Gunungkidul region is from accumulated surface water in doline or other accumulated water body. The water itself isn’t without problems. The most common problems are pollutants which come from sediments and limestone solution. These problems makes the water is unable to consume.

The potential water in doline or in other basin with major surface area can be evaporating because of the heat source from solar energy. The purpose of this research is to produce water with good quality by using evaporating pyramid named “LIMAS EVAPORASI”. The research take place at Jeluk Jonge doline in Gunungkidul’s karst area because the lack of water for drink and domestic use. The result of this research is drinkable condensed water vapor with good quality. The condensed water vapor is drinkable because the pollutants and several chemical elements are not evaporated and stay in the water body.

In this research, we found out that the evaporating pyramid is able to catch the water vapors in it four-sided flank, condense and patch it in a storage bottle. The main problem, the instrument is still low in efficiency because the solar heat is fluctuated and not able to maintain its capacity to evaporated water. The assumption that researchers use is the ideal average water reduction for doline surface is 0,5 cm per days. If this condition is not fulfilled, it makes the quantity of condensed water vapor is not alike as it should be in ideal condition.

Key words : evaporation, condensed water vapor, evaporating pyramid
