PERANCANGAN PERANGKAT DESTILASI AIR LAUT MENJADI AIR TAWAR MENGGUNAKAN SOLAR CONCENTRATOR DENGAN SISTEM SIRKULASI

Abstract

The design of the seawater distillation device into fresh water is designed to be a single unit so that it causes shading in the solar concentrator, which causes less than optimal results. In this study, the use of a solar concentrator with a circulation system is designed by designing a parabolic trough solar concentrator and a distillation greenhouse separately so that it can capture the sun's heat temperature more optimally. Then the ds18b20 sensor is installed as a sensor that will measure the temperature of the flowing water and the water in the container, as well as the dht22 sensor to measure the temperature in the greenhouse room. Ultrasonic sensors are used to determine the volume of fresh water, the results of this design are able to help increase the heat value in the greenhouse by ± 1.09°C and produce ± 40 ml of fresh water for 5 hours. The highest temperature was obtained in the time range 10:00 – 14:00 WIB with an average value of 38.99°C temperature in flowing water, 39.24°C water temperature in the tub, 39.76°C temperature in the greenhouse and 31.27°C ambient temperature.
