Abstract

Coastal communities have had difficulty in getting drinking water or freshwater. The solution is to distill seawater into fresh water through the implementation technology of the solar distillation pyramid type. This technology utilizes solar thermal energy (greenhouse effect) and to help speed up the condensation process watering is done on the roof of the distillation. This research aims to determine the performance of the solar distillation pyramid type with the dripping water method and determine the effect of water treatment on the roof of the greenhouse on the temperature with the volume of water produced from the distillation process of seawater. About 4000 mL of seawater put into the distillation, then the heating process will be carried out by sunlight, which causes seawater to evaporate on the roof of the distillation and to accelerate cooling by water on the roof so that differences in ambient temperature and inside distillation. The water vapor that is formed will turn into water and drip on the walls of the glass room which is then accommodated by waterways and reservoirs. The research results efficiency of solar distillation type pyramid about 27.13%. With the method of dripping water method obtained as much as 2317 mL of freshwater, whereas if without watering treatment about 2057.5 mL.
