Solar still is one of the technologies which are used to desalinate saline water. Unlike the other conventional desalination units, this machine uses solar energy as its main source of energy, makes it more environmental friendly. Unfortunately, not all of the energy received by this unit can be utilized. Consequently, the performance of this unit is relatively low despite of its ease of operation. Therefore, this research is conducted in order to evaluate the effect of insulation thickness and water depth inside the basin on the performance of solar still. This experiment uses single basin solar still with single slope glass cover whence heating, evaporation, and condensation occur at the same place. Result shows that adding additional thick of insulation can increase the productivity and the efficiency of the unit. Meanwhile, the more volume of water filled inside the basin, the less distilled water will be produced for the same insulation thickness. In this attempt, the shallowest water depth (1 cm) and the thickest insulation used (1.6 cm) produces the most distilled water and has the highest efficiency among the other variations conducted. In addition, giving side insulation enhanced the still efficiency to 22%. The water quality from the conducted solar desalination has met the drinking water quality standard according to Ministry of Health Regulation No. 492 year 2010 for TDS and pH. Additionally, salinity and conductivity levels of the distilled water also decrease significantly from the quality found in the feed water.
