Abstract

Solar energy as renewable energy has great potential to supply the world's energy needs. Solar thermal energy can be used for domestic energy purposes (cooking and water heating). The purpose of this research is to develop, design and analyze the performance of a solar cooker from the concentration of direct normal irradiance (DNI) by the Fresnel lens on the receiver/absorber as a cooking vessel. One form of improving the performance of the Fresnel solar concentrator (FSC) is the addition of an automatic solar tracker installation using hydraulic actuators. The solar tracker is varied, every 5 and 10 minutes, respectively. The solar cooker performance test was conducted outdoors at the Mechanical Engineering Department of State Polytechnic of Malang (7.9553 oS and 112.6125 oE) in April 2021. The method used actual experimental research. The measurement of solar radiation uses a solar power meter SPM-1116SD and the tracker's movement. At the same time, the temperature parameters (water temperature, receiver wall temperature, focal point temperature, ambient temperature) are measured by the temperature data logger. The concentrated solar cooker type design uses a fresnel lens with a capture area of 0.785 m2 and a focal ratio of 0.88. The main components of this solar cooker design consist of: a large fresnel lens that functions as a concentrator of sunrays, a cone-shaped cooking stove as a solar collector (receiver), and a hydraulic actuator-type solar tracker unit. Initial tests showed that the solar radiation, In = 789.00 W/m2, obtained the focal point temperature at the receiver, Tf = 930.10°C. Meanwhile, the thermal efficiency (Th) of a solar cooker with a solar tracker that moves every 10 minutes and 5 minutes is 12.7% and 33.66%, respectively. The increase in the thermal efficiency of the solar cooker is very significant, which is 2.65 times. This shows that the more accurate and continuous movement of the tracker will increase the thermal efficiency of the designed Fresnel solar cooker.

Abstract

The Aims of this study are to determine  the effect of embossing roll roughness and forming temperature on the damage of menthol-coated aluminum foil on the packaging, and to determine the best temperature and embossing roll roughness on the quality of the menthol coating on the packaging. In this study, the independent variables were embossed roll wave (roughness level 1000,500.0 µm) and menthol foil temperature (22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46 °C) to be manipulated, observed, and measured to know the effect with the dependent variable. And because the established variable is the quantity of broken menthol foil packaging that is measured via way of means of calculating the share of period of menthol foil packaging this is torn as compared to the whole period of the foil. Based on the effects of the discussion, it can be concluded that the forming temperature and the embossing roll roughness affect the damage to the menthol packaging layer. In the ANOVA follow-up test, the lowest and best mean value for the forming temperature is at T12 or 44°C, not at T13 or 46°C because at these temperatures the menthol layer on the package is too hot and starts to damage the coating and the lowest and best average for the roughness level of embossed rolls is at E3 with a roughness value of 0 µm (fine).
