Indonesia is a country that has abundant solar energy. Cooking with solar energy is one way to reduce dependence on fossil fuels. In this research, a Fresnel solar cooker (FSC) will be designed with a solar tracker. PMMA Fresnel lens is used to concentrate Direct Normal Irradiance (DNI) in a cooking pot with a conical cavity receiver cover. The thermal performance of the FSC was investigated by simulation and experiment. The simulation results show that the disorientation of the focal point causes a deceleration in the thermal distribution. The experiment results show that the focal point temperature of the Fresnel is influenced by Direct Normal Irradiance (DNI). The increase in solar radiation produces a focal temperature, exponentially. The test results show that DNI = 862.50 W/m2 can produce a focal temperature, Tf = 1064.00°C. © 2023 Author(s).
