This paper presents an experimental performance study of a stepped type solar still for processing seawater into salt and fresh water. Its performance was tested in Padang City, under Indonesian environmental conditions. The experimental setup this study consisted of a tank of seawater, solar distillation and distilled water storage tanks. The working principle is the distillation of sea water put into the basin to be heated with solar power. The water will evaporate and condense on the surface of the cover glass distillation, distillation of fresh water stored in the container. Warming in the distillation carried out continuously until the water evaporates and the depleted salt crystals formed in the basin. The result shows that the productivity of the solar still was highly affected by the increase in solar radiation and ambient temperature. The productivity was 176 gr salt and 3,662 ml water with the average solar intensity 566 W/m². The time it takes to produce salt is fourdays.

本文介绍了阶梯式太阳能蒸馏器将海水加工成咸水和淡水的实验性能研究。它的性能在印度尼西亚环境条件下的巴东市进行了测试。本研究的实验装置包括一个海水罐、太阳能蒸馏罐和蒸馏水储存罐。工作原理是将海水蒸馏后放入盆中，用太阳能加热。水会蒸发并凝结在蒸馏盖玻璃表面，蒸馏容器中储存的淡水。蒸馏中的升温持续进行，直到水蒸发并在盆中形成耗尽的盐晶体。结果表明，太阳能蒸馏器的生产力受太阳辐射和环境温度升高的影响很大。² . 制盐的时间是四天。
