The increasing demand for alternative energy sources has encouraged the utilization of waste materials as renewable energy resources. Waste cooking oil is one of the potential fuels that can be converted into thermal energy due to its availability and energy content. This study aims to experimentally analyze the performance of a small-scale Stirling engine using waste cooking oil as an alternative heat energy source for energy conversion systems. The experimental method was applied by operating the Stirling engine with heat generated from waste cooking oil combustion and evaluating its performance based on operating temperature, temperature difference between the hot and cold sides, rotational speed, and mechanical output. The results showed that waste cooking oil was capable of providing sufficient thermal energy to operate the Stirling engine. Engine performance was influenced by heat transfer effectiveness, combustion stability, and temperature gradient. The findings indicate that waste cooking oil has potential as an environmentally friendly heat source for small-scale Stirling engine applications. This study contributes to the development of renewable energy conversion technology by utilizing waste resources and improving the sustainability of small-scale energy systems.
