Biodiesel is one of the alternative energy sources for diesel oil substitutes. However, the unsaturated fatty acid contains in vegetable oils leads to the poor oxidation stability of biodiesel. One of the potential methods used to prevent or delay the oxidation reaction is the addition of antioxidants because the process is much more straightforward and efficient. Soursop leaf was reported to have the potential to be used as a natural antioxidant. Soursop leaf extracted using solvent n-hexane and ethyl acetate. The crude extract with concentration 0, 100, 200, 300, 400 ppm tested to palm oil and soybean oil biodiesel. Oxidation stability of biodiesel analyzed using the 873 Rancimat instrument biodiesel. The results show that a concentration of 100 ppm soursop leaf extracted with both n-hexane and ethyl acetate increased the Induction Period (IP) of palm oil biodiesel more than 16 h. This result meets the SNI biodiesel requirements in which the IP minimum for biodiesel is eighth.
