Biodiesel is one of the alternative Fuels to replace petrodiesel. This environment friendly fuel is synthesized by transesterification reaction of vegetable oil or animal oil. Beside having excellence such as environment friendly and biodegradable, biodiesel has weakness namely it has higher cloud point than petrodiesel. This causes problem when it is used in the cool climate Country. This physical behavior is influenced by the composition and molecule structure of fatty acid ester as the biodiesel compound. One of the method used to reduce the cloud point is making ramification at aliphatic chain that will bother the molecule structure unity in compiling crystal lattice. The objective of this research is to synthesize biodiesel from cooking oil waste by giving ramification at side chain to reduce the cloud point. The experimental method used is to react the biodiesel with hydrogen peroxide in order to opening the double bond becomes epoxide, then it is acetylated to be acetyl ester metyl. The experimental result indicates that the biodiesel made of cooking oil waste has lower cloud point (10,9 degree C) than the biodiesel made of palm oil (16,2 degree C).
