The fresh water crisis is a global issue that has threatened human life in recent years. In areas with a lack fresh water resources, quality enhancement of saline water, the most abundant water resources in nature, by using desalination process become a promising solution to be used. According to ecological friendly and sustainability effort, renewable energy-based desalination is one promising choice to address this issue. This research aims to determine a performance of innovative hybrid solar desalination system, that use several materials that accelerate evaporation on the surface and store a heat, which is predicted to have significant potential for application in desalination technology. The research consists of two parts of experimental section that started with determining the optimum conditions for the HSDS, that conducted to determine the optimum feed water flow rate and the optimum initial feed water concentration, followed by the HSDS system performance study that conducted to determine the effect of heat storage materials and cooling water flowrate in vacuum condition. The performance of the developed hybrid solar desalination system is quite high with hourly yield of 28.03 L/m2 over 5 hours, and the optimum desalination efficiency of 55.42%, which was obtained at a cooling water flowrate of 4 L/minute, and the use of black gravel. The energy supplied to the system ranges from 13,064-15,506 kJ, with an energy consumption of 9,415-9,601 kJ. Meanwhile, energy loss within the system was 3,463-6,091 kJ, or approximately 26.51-39.28% of the energy supplied to the system. At optimum conditions, the thermal efficiency and gain output ratio (GOR) of the HSDS was 58.7% and 1.32 respectively
