The technology of distilling seawater into fresh water has been carried out with various models and methods. The distillation process is one of the effective methods to get clean water by utilizing solar energy as the main energy source. The model is planned for a dual slope active system with a basin area of 1,932 m 2 wide with 1 m 2 glass surface with two pieces with 3 mm glass thickness and 15° glass slope angle. The water level from the bottom of 20 mm is kept constant and given a fog that circulates the water in the basin. The lowest solar intensity was 186.9 SR,W/mA 2 with the amount of energy absorbed 20.9761 W/m 2 , and the highest solar intensity 700.6 SR,W/mA 2 with the amount of absorbed energy 1813,667 W/m 2 °C. The energy efficiency obtained from the results of the discussion of the highest test results data on the seventh day reached 77.92 %, and the lowest efficiency on the second day was 66.1853 %.
