EVALUASI SIFAT FISIK DAN KETANGGUHAN IMPAK ALUMINIUM MATRIKS KOMPOSIT BERPENGUAT 3% PKSA DAN 1% SIC MENGGUNAKAN METODE STIR SQUEEZE CASTING

The rapid growth of the palm oil industry in Indonesia generates a large amount of solid waste that poses environmental pollution risks. One such by-product is palm kernel shell ash (PKSA), which contains silica and therefore has the potential to be utilized as reinforcement material in metal matrix composites. This study aims to analyze the effect of reinforcement particle addition and variations in applied load during the stir-squeeze casting process on the physical and mechanical properties of an Aluminium Matrix Composite (AMC) based on Aluminium 6063 alloy reinforced with 3% PKSA and 1% silicon carbide (SiC). The squeeze-casting process was performed with load variations of 3 tons, 6 tons, and 9 tons. The tests conducted included impact testing, fractography, microstructural analysis, density measurement, and X-Ray Diffraction (XRD). The impact test results showed average absorbed energy values of 7.79 J/mm² at 3 tons, 3.22 J/mm² at 6 tons, and 11.40 J/mm² at 9 tons. The highest density value of 2.678 g/cm³ with the lowest porosity of 0.07% was obtained at 9 tons of pressure. Microstructural analysis revealed a more homogeneous distribution of reinforcement particles as well as stronger and denser intergranular bonding with increasing applied pressure, while XRD results identified the presence of Al, SiO₂, and SiC phases contributing to the improvement of the material’s mechanical strength. Overall, the increase in applied pressure significantly enhanced the mechanical properties and microstructural characteristics of the AMC, demonstrating that the utilization of PKSA can support the development of high-performance composite materials with superior characteristics.
