In this study, a solar pond prototype is used to analyze the temperature and salinity gradients of alternative energy source processes. The study used two types of solar pond to investigate the temperature and salinity of gradients from each solar pond. The first solar pond utilizes sunlight as a heat source that emitted directly on the solar pond and the second solar pond utilizes the spotlights as a direct heat source emitted on the solar pond. The first solar pond is made of a cylindrical plastic tank of 1.05 m tall, 0.8 m in diameter placed outdoors in direct sunlight and the second solar pond model is made of a trapezium plastic tank with a height of 0.9m, the upper diameter 0.54m and a bottom diameter of 0.49m placed indoors with floodlights. The gradient temperature salinity and temperature measurement in the fest solar pond are smaller than temperature in the second solar pond however, the T 3 temperature in the outdoor solar pond is larger than the indoor solar pond. The observation results show that the first solar pond generates the mean value of temperature and salinity of successive gradients 32 (°C); 30 % and the second solar pond has the average value of temperature and salinity of successive gradients 31 (°C); 28 %.
