Abstract
Biodiesel is an alternative fuel that is produced conventionally through the
transesterification reaction of triglycerides or oil with short-chain alcohols and a
catalyst. This research aims to increase the catalytic ability of the catalyst by
modifying the CaO catalyst from blood cockle shells with SiO2 derived from
areca palm ash through the impregnation method for use in the biodiesel
production process. SiO2 impregnated with ratios of 3% w/w to the weight of
CaO. The resulting catalyst was applied for biodiesel production with yield
optimization using Response Surface Methodology (RSM) with a Box Behnken
Design (BBD) design. Analysis using BET shows that the surface area of CaOSiO2
3% has increased. XRF analysis of the 3% CaO-SiO2 catalyst obtained a
CaO composition of 97.44%. At the optimum condition highest biodiesel yield
was 95.95%
