Abstract

The utilization of solar energy as a renewable energy source is becoming increasingly important to reduce dependence on fossil fuels. One of its applications is the parabolic reflector solar cooker, which harnesses solar radiation for cooking purposes. This study aims to evaluate the performance of a solar cooker equipped with a parabolic reflector through a water heating test. The study presents an analysis of the performance of a solar cooker using a parabolic reflector collector. The solar reflector was constructed from mirror fragments arranged to form a parabolic shape with a surface area of 1.05 m². The experiment was conducted in the Lhokseumawe region, Aceh Province, Indonesia, located at coordinates 5°12’11.01’’ N and 97° E, with an altitude of 18.3 m above sea level. Performance measurements were carried out using a water heating method with a vessel containing 3.2 kg of water placed at the focal point of the reflector. The solar radiation received by the collector was reflected toward the focal point, heating the water directly. The results showed that the water temperature increased to 82.4 °C within 60 minutes, from 12:00 to 13:00 local time (WIB). The overall efficiency of the solar cooker was found to be 33.9%. These findings indicate that the parabolic reflector solar cooker has strong potential as an environmentally friendly alternative energy source suitable for application in tropical regions

Abstract

Today's technological growth is very rapid, companies continue to develop in technological innovation in their products. At the same time, it is necessary to increase adequate energy such as electric power, chemical power, and renewable alternative fuels to replace diesel oil, namely Biodiesel. As of January 2020, the government has implemented a fuel mixture for the transportation sector containing 30% biodiesel in diesel oil. There are many types of biodiesel processing technologies, including non-catalyst technology. This technology only requires raw materials in the form of oil and methanol, without using a catalyst. The use of methanol in the form of superheated vapor in a non-catalyzed response requires equipment that can replace liquid methanol into superheated methanol vapor. The conversion of methanol to superheated methanol in this research was carried out using a methanol preheater based on a design from previous research using the ChemCAD application. namely heating methanol indirectly through a heating fluid in the form of Mobiltherm 605 thermal oil. With mobiltherm hot at a temperature of 50ºC, the pump performance results are obtained with Capacity (Q) 0.0003 m^3/s, Head (H) 0.019 m, Power hydraulic (N_h) 119 watts, and efficiency (η) 95.2%. The greater the value of the density of the fluid, the greater the power used. In the case of Mobiltherm, which has a different fluid viscosity from water, the hydraulic power and efficiency obtained are also high. The mobiltherm 605 heat transfer rate is 35% through the double pipe annulus and the methanol temperature rate through the double pipe inner pipe
