ANALISIS KARAKTERISTIK FISIK DAN MEKANIK KOMPOSIT AL-6063 BERPENGUAT 1% PKSA DAN 3% SIC DENGAN METODE STIR-SQUEEZE CASTING

The rapid development of the palm oil industry in Indonesia has generated large amounts of biomass waste, one of which is Palm Kernel Shell Ash (PKSA), a potential reinforcement material for metal composites due to its high silica content. This study aims to investigate the effect of adding PKSA and silicon carbide (SiC) on the properties of Aluminum 6063 composites fabricated through the stir–squeeze casting method. The composite was produced using stir casting with a composition of 3% SiC and 1% PKSA, followed by squeeze casting with applied loads of 3, 6, and 9 tons right after stirring while the composite material was in a semi-solid stage. The tests included Brinell hardness Test (BHN), microstructural analysis, Scanning Electron Microscopy (SEM), and X-ray Fluorescence (XRF). The results showed that the addition of PKSA and SiC reinforcing particles, along with the increase in applied pressure during squeeze casting, led to a gradual improvement in material hardness. Average BHN increased by 8.57% at 3 tons, 19.54% at 6 tons, and 20.75% at 9 tons compared to unreinforced aluminum. This enhancement was attributed to stronger interfacial bonding and grain refinement, which limited dislocation movement through denser grain boundaries. Microstructural and SEM analyses revealed finer grains and more homogeneous particle distribution, while XRF results confirmed increased Si and Mg contents contributing to hard phase formation such as SiO₂ and Fe₃Si. Overall, the combined addition of PKSA–SiC and the stir–squeeze casting technique effectively improved the physical and mechanical properties of Aluminum 6063 composite.
