Currently, the development of materials to improve the efficiency of fuel usage is increasingly carried out, one of which is a matrix composite. The stages of making composites in this study started from the preparation of magnesium matrix and Si3N4 reinforcement to casting with a stirring casting method. The addition of Si3N4 reinforce was carried out by varying the volume fraction by 2 vf-%, 4 vf-%, 6 vf-%, and 8 vf-% which was then characterized by metallographic testing, SEM-EDS, tensile testing, hardness, impact, wear, density and porosity, and XRD. The results of this study showed an increase in mechanical properties by adding Si3N4 as reinforcing particles. The magnesium composite produced different mechanical properties in each variation of the addition of the reinforce. The best mechanical properties resulted from the addition of a reinforce is with a volume fraction of 8 vf-% which produced a hardness value of 94 HRH and a wear rate of 0.0045 mm3/m.
