We use freshwater to fulfil our activity, but the majority of water is classified as saline water. Saline water can be processed to become freshwater (desalination process), but the downside of using those technologies is the cost of energy that need to run the process. Using electrical power to run saline water treatment will make the process expensive, especially for coastal areas with bad energy resource and distribution. Renewable energy can become an alternative to power saline water desalination. Solar radiation is one of the renewable energies that can be used because thermal radiation from solar energy can be applied to drive desalination directly. This research aims to analyse production desalinated water volume to physical properties, water quality, and chemical removal from the desalination process. By making one set of multilevel solar still desalinator and run it using artificial saline water with concentration 15 gram/L for 3 days and 40 gram/L for 3 days, it can produce up to 509 ml freshwater by running desalinator from 09.00 to 15.00. Desalination process can remove 100% salinity, up to 99.90% of Chlorine ion. The pH of freshwater that produced quite low, the lowest pH is 5.45.
