Abstract

The sun is an abundant and never-ending energy source, and the conversion is relatively easy, cheap, not influenced by economic, political conditions and pressures from developed countries. Langsa City receives an average annual solar radiation intensity of up to 600 W/m2. One way to get this massive amount of solar energy is by concentrating the radiation emitted by the sun to a single focal point, or better known as Concentrated Solar Power (CSP). This study aimed to utilize CSP technology using a parabolic reflector applied to the seawater desalination process. The parabolic reflector is made of an iron plate with a thickness of 0.5 mm, and 80 cm in diameter. The focal point distance is 50 cm. Many small mirrors are glued to the parabola’s surface to fill the surface area of the parabola. This mirror serves to reflect sunlight to the focal point. The reflector is then mounted on a frame made of ½, ¾, and 1-inch steel. The frame is 1 x 1 x 1 m in dimension. The testing of the prototype was carried out for three days at different times. The temperature measurement at the focal point shows a maximum value of 147.3°C at a daily average solar radiation intensity of 500-600 W/m2. The freshwater product obtained from desalination using this parabolic reflector is 224 mL for an operational time of 8.5 hours.
