Abstract
Dog-conch snail waste can be used in the research field. Dog-conch snail shells contain
carbonate compounds (CaCO3) which can be conversed to CaO through a calcination
process at a temperature of 700-900 ºC. CaO is an active catalyst in the
transesterification biodiesel reaction. One of the thing that can we do to increase the
effectivenes of CaO catalyst in biodiesel production is by impregnated the alkaline
metal in CaO. The alkaline metal insertion progress is by impregnating KOH on CaO.
Biodiesel production using dog conch shell catalyst was carried out at calcination
temperature of 900 ºC for 10 hours, impregnated with K 1, 3, 5% and calcinated again
at 600 ºC for 5 hours. The results of functional group analysis using Fourier Transform
Infra Red (FTIR) show the presence of an OH group in the wave number
(3200-3650 cm-1). The optimum yield bioidesel was 84,24% with catalyst weight of 3%
CaO 1:6 mole ratio of oil and methanol, 3 hours reaction time and 60 ºC temperature
reaction.
