Wet impregnation method was used to produce heterogenous catalyst. The catalyst are having 5 different composition, which are 10:0, 2.5:7.5. 5:5, 0:10 and 7.5:2.5 of calcium oxide: silica. The seashells and rice husk (source of calcium oxide and silica) were used for catalyst’s making. The effects of different ratio of both catalyst’s sources were studied. Transesterification method is a method in which an ester reacts with an alcohol to form a new ester and different alcohol, with the presence of catalyst. The goal is to convert triglycerides in waste cooking oil into fatty acid methyl esters and glycerol as byproducts. The conversion was suppose at least 60% of FAME’s production with 5:5 of CaO:SiO2 catalyst usage. However, the conversion was way far than the expected result though the biodiesel conversion was 81.71%. This situation is might due to the catalyst preparation. specialized Jihan Fadila Hakim Binti Eko Budi Santoso Faculty of Industrial Sciences and Technology Final Year Report (Bachelor of Applied Science of Industrial Chemistry) -- Universiti Malaysia Pahang Al-Sultan Abdullah - 2025 Include bibliographical reference Faculty of Industrial Sciences and Technology Dissertations Universities and colleges Dissertations Theses Dissertations THE0010478 (Local) https://umpir.ump.edu.my/id/eprint/46112 https://umpir.ump.edu.my/id/eprint/46112 UMPSA 260420 20260420150453.0 eng
