Synthesis of Ni-NH2/mesoporous silica bifunctional catalyst for conversion of used cooking oil into biofuel was carried out. The impregnation of Ni into the MS8 with a specific surface area of 666.6 m2/g, volume pore of 0.46 cm3/g, and diameter pore of 4.9 nm was done by wet impregnation method. The functionalization of NH2 into the MS8 and Ni/MS8 was done by the grafting method. The catalytic activity test in used cooking oil hydrocracking was done by thermal (without catalyst), catalyst physical mixture of Ni/MS8 and NH2/MS8, and Ni-NH2/MS8 bifunctional catalyst. The results showed that the Ni/MS8 catalyst with acidity values ​​of 12.804 mmol/g was successfully modified with amine groups to produce Ni-NH2/MS8 bifunctional catalyst. This catalyst was utilized in the hydrocracking process of used cooking oil to produce the highest liquid product of 92.85 wt.% with the selectivity of gasoline and diesel fractions of 4.04 and 63.35 wt.% respectively.
