ABSTRACT: Aluminum matrix composites (AMC) has been widely known to be used in a wide range of aircraft, automotive and industrial infrastructure applications, due to its mechanical and physical properties. In this work, AMC were fabricated through stir casting method with the Taguchi method to analysis significant contribution of parameter process in term of hardness property. For this purpose, the effects of various parameter processes pertaining during stir casting were performed have to be optimized. Aluminum alloy was used as a matrix with combination of various reinforced materials is fly ash, Silicon Carbide (SiC) and Alumina (Al2O3) with stirring speed (100, 200, and 300 rpm), stirring time (2, 4, and 6 min) and pouring temperature (700, 750 and 800 ºC). Results showed that composition was significant contribution percentage (41.97%) otherwise pouring temperature was minimum contribution (0.675%) to influence hardness.
