ANALISIS FISIK DAN KETANGGUHAN IMPAK AMC BERPENGUAT 1%PKSA DAN 3%SIC MELALUI METODE STIR-SQUEEZE CASTING

The palm oil industry in Indonesia produces large amounts of biomass waste, one of which is palm kernel shells that have the potential to be used as composite reinforcing materials. This study aims to utilize PKSA resulting from combustion at 900°C for 4 hours as an additional reinforcement in aluminum 6063-based aluminum matrix composites (AMCs). The use of PKSA containing SiO₂ is expected to reduce the use of silicon carbide (SiC) particles without compromising material performance. The composite manufacturing process was carried out using the stir-squeeze casting method, which is a combination of the stir casting and squeeze casting processes aimed at improving the distribution of reinforcing particles, reducing porosity, and improving the mechanical properties of the material. The pressure variations used were 10.41 MPa, 20.82 MPa, and 31.24 MPa. The tests conducted included Charpy impact testing, fractography, microstructure observation, density, and X-ray diffraction (XRD). The test results showed that the overall impact value of the sample was lower than that of the aluminum as received, with the lowest value at a pressure of 31.24 MPa due to an increase in the heat transfer coefficient that accelerated freezing. Specimens at a pressure of 10.41 MPa showed a coarse fracture morphology and finer but not yet homogeneous grains. The AMC density value was lower than that of as-received aluminum, indicating the potential for developing this material for lightweight engineering applications. XRD analysis showed the presence of a stable crystalline phase that was well formed through the stir-squeeze casting method
