Fuel derived from petroleum is a non-renewable energy source, the existence of which is very limited so it is necessary to seek alternative fuels. Biodiesel as an alternative fuel in the manufacturing process can use Moringa stem as a catalyst mixture with CaO. The purpose of this study was to determine the effect of Moringa stems that received traditional cooking treatment, heating at a temperature of 600°C with a duration of 3, 4, and 5 hours and without treatment in the process of making biodiesel with used cooking oil as the base material. The manufacturing method uses the esterification and transesterification process at a temperature of 60°C, the analysis is proximate and FTIR. Proximately obtained in biodiesel the content of the highest volatile compounds in Moringa stem powder without treatment was compared to CaO alone and the FTIR spectrograms were similar with differences in absorption.
