Abstract

Logam akan mengalami perubahan fasa selama proses pengecoran, baik perubahan sifat fisis maupun mekanik yang disebabkan oleh proses pembekuan. Perubahan sifat ini antara lain dipengaruhi media pendingin yang digunakan pada saat proses pendinginan. Tujuan penelitian ini adalah untuk membandingkan variasi temperatur pendinginan terhadap kekerasan hasil coran aluminium karena sifat fisis dan mekanis suatu logam sangat penting dalam kontruksi permesinan. Maka dalam penelitian ini digunakan media pendinginan yang berbeda yaitu : Air dengan suhu 15°C, Air dengan suhu 27°C dan Air dengan suhu 55°C. Dari pengujian kekerasan benda uji dengan media pendinginan air suhu 15°C mempunyai nilai kekerasan yang lebih baik dibanding air dengan suhu 27°C dan 55°C. Dari hasil pengujian komposisi kimia terdapat 17 unsur, tetapi hanya 4 unsur yang paling berpengaruh pada aluminium cor yaitu Si, Fe, Cu, dan Zn yang paling dominan. Dilihat dari unsur yang ada pada material ini dapat digolongkan logam aluminium paduan seng (Al-Zn).

Abstract

This study aims to determine the effect of the heat treatment process and pressing on hardness, density, and morphological changes in the microstructure of Al-Si alloys. In this study, the medium used was coconut shell charcoal with a mesh size of 80 at a heat treatment process of 400 °C and a holding time of 75 minutes. The pressing was carried out with a load of 150 N. The result of this research is an increase in the hardness of the Al-Si alloy with an average value of 133 VHN after the Heat Treatment and pressing process. In the microstructure, there is a morphological change in the Al-Si alloy with the reduction of Si elements and also an increase in the density value after the heat treatment process.

Abstract

This study explores the potential of nanoscale silicon carbide (SiC) particles synthesized from rice husk ash to enhance light absorption characteristics in solar panel applications. The SiC particles were produced by burning rice husks, followed by purification and division into two groups: one group underwent heat treatment at 400 °C, while the other was kept untreated for comparative analysis. High-Energy Milling (HEM) for 60 hours was used to reduce the particle size of selected samples. Comprehensive characterization was performed using Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and UV-Vis spectroscopy in the wavelength range of 200–1100 nm. The results of the study indicate that heat-treated SiC exhibits significantly reduced agglomeration and better particle dispersion compared to untreated samples. FTIR analysis confirmed the presence of additional functional groups (C=C and O–H) in the treated SiC, which contribute to surface chemical modification. Most importantly, the UV-Vis spectra show that the treated SiC maintains consistently higher absorbance values (0.5–0.6) in the visible to near-infrared region (400–1100 nm), whereas the untreated SiC exhibits a decreasing trend (0.4–0.2). These findings suggest that thermal processing can enhance the optical performance of SiC nanoparticles by improving dispersion and introducing functional groups that strengthen light-matter interactions. The superior absorption characteristics of the processed SiC demonstrate promising potential as an additive or nanostructured layer to improve photon capture and overall efficiency in photovoltaic devices
