Calcium oxide (CaO) is one of the most commonly used heterogeneous base
catalysts in the biodiesel synthesis process. The high CaCO3 content in the blood
clam shell can be used as a catalyst in the synthesis of biodiesel using crude palm
oil (CPO). Biodiesel production using a KOH/CaO catalyst derived from blood
clam shell. KOH/CaO catalyst was synthesized using the sol-gel method by mixing
6 g of calcined CKD powder at 900 oC for 5 hours with variations of KOH (0,5; 1
and 2) g and 12 mL ethylene glycol. The catalyst was characterized by using the
Surface Area Analyzer instrument using the BET method to determine the surface
area of the catalyst and FTIR to determine the functional groups contained in the
catalyst. The surface area of (0.5 and 1) KOH/CaO at 700 oC were (0,51 and 0,99)
m2/g, and for 1 KOH/CaO the calcination temperature was 500 and 600 oC were
(10,51 and 2,47) m2/g. The OH functional group has been formed at the wave
number 3642,73 cm-1 which indicates Ca(OH)2. The catalyst was tested in the
synthesis of biodiesel using various weights of catalyst (1, 2, 3 and 4) wt% and mole
ratio of oil : methanol (1:6, 1:9, 1:12, 1:15 and 1:18). Optimum biodiesel was
obtained at 1 KOH/CaO catalyst at 700 oC with a catalyst weight of 1 wt%, a mole
ratio of oil to methanol 1:15, a reaction time of 3 hours, agitation speed of 500 rpm,
and a temperature of 60 °C with a yield of 94.92%. The characteristics of the
biodiesel produced were 0.01 v/v% water content, specific gravity 883 kg/m3,
viscosity 5.38 mm2/s, carbon residue 0.01 wt%, acid number 0.42 mg-KOH/g.
Saponification number 225,95, the iodine number 50.44 g-I2/100 g and the cetane
number 59,10. In general, the characteristics of biodiesel are in accordance with the
requirements of SNI 7182-2015.
