In this work, calcium oxide (CaO) extracted from eggshell impregnated with magnetite (Fe<sub>3</sub>O<sub>4</sub>) is prepared successfully and it had been applied on transesterification of palm oil off-grade. Prior experiment, the eggshells material are powdered and calcined at 900 °C then impregnated with Fe<sub>3</sub>O<sub>4</sub> and recalcined. The obtained Fe<sub>3</sub>O<sub>4</sub>/CaO catalyst is characterized using X-ray diffraction and Braunaeur−Emmet−Teller (BET) surface area. The influence of various parameters including recalcined time and temperature are investigated. The prepared catalyst is tested for transesterification of palm oil off-grade to produce biodiesel in which the optimal conditions of a methanol/palm oil off-grade molar ratio of 10:1, the catalyst weight of 6%, the reaction temperature of 70 °C, and the reaction time of 2 h.
