Biodiesel is one of the renewable alternative fuels as a substitute for fossil fuels. This research aims to study the effect of catalyst loading on the synthesis of biodiesel from lard. The transesterification reaction is carried out using a CaO catalyst prepared from an eggshell. Esterification is carried out by using an HCl acid catalyst to lower the free fatty acid (FFA) of lard. The catalyst loading is varied on 1, 3, 5, and 7% w/w of lard. The molar ratio of methanol to oil is 6:1 with a reaction time is 1 h, while operating conditions were kept at a reaction temperature of 65°C and atmospheric pressure. The results showed that the yield of biodiesel decreased with the increase of catalyst loading. The optimum biodiesel yield was obtained at 1% w/w catalyst loading of 92.69%.
