【 摘 要 】

Waste cooking oil is a renewable energy source that is easily obtainable in a domestic environment. This energy source can be used as a substitute for diesel fuel known as biodiesel. Biodiesel can be produced from the process of esterification and transesterification reagent used cooking oil with ethanol. The content of fossil fuels as an energy source in general can be seen from the content of the main elements of which are carbon and hydrogen. The purpose of this study to determine the content of carbon, hydrogen, and acid in biodiesel produced from waste cooking oil and ethanol reagent using phosphoric acid catalyst in the process of esterification and sodium hydroxide in the transesterification process. Ultimate analysis was conducted by using ASTM method D7582 Biomass and acid number is determined by titration. The results Showed that the content of biodiesel from waste cooking oil with ethanol reagent pro analysis or ethanol from wine and distillate results are carbon and hydrogen as the main element contained as fuel in general. Percentage of Free Fatty Acids (FFA) and Acid Value in biodiesel highest in ethanol reagent pro analysis.
