Abstract

Daur ulang aluminium melalui proses peleburan kembali sering mengalami perubahan sifat mekanis dan struktur mikro akibat kontaminasi atau kehilangan unsur paduan. Penelitian ini bertujuan menganalisis pengaruh penambahan timah (Sn) pada hasil pengecoran aluminium dari bahan piston bekas terhadap sifat mekanis dan struktur mikro material. Variasi penambahan timah adalah 20%, 30%, dan 404% berat. Hasil penelitian menunjukkan penambahan timah berpengaruh signifikan pada nilai kekerasan. Penambahan 20% timah menghasilkan peningkatan kekerasan sebesar 68,014 N/mm2 yang optimal. Penambahan penambahan 40% timah menurunkan nilai kekerasan sebesar 55,857 N/mm2 karena disebabkan terbentuknya fasa lunak dan rongga pada struktur mikro. Fasa intermetalik aluminium-timah pada penambahan 20% timah berkontribusi pada peningkatan kekerasan. Penelitian ini memberikan informasi berharga tentang komposisi paduan optimal untuk meningkatkan sifat mekanis aluminium hasil pengecoran daur ulang piston bekas.

Abstract

Optimizing laboratory management is support safe and effective learning activities. In the Design and Machining Process Laboratory, Faculty of Engineering, equipment operation has largely depended on verbal instructions from laboratory staff, increasing the potential for operational errors & workplace accidents. This commu nity service program aimed to develop digital equipment operating manuals integrated QR Codes to improve users' independence in laboratory activities. A participatory approach was employed through needs assessment, equipment inventory, manual develop ent based on technical references and occupational health and safety standards, integration into QR Code-linked digital flip books, dissem ination, and evaluation. The results demonstrate that the digital manuals can be accessed instantly by scanning QR Codes attached to each piece of equipment, enabling students to obtain operational guidance independently. This innovation enhances the effectiveness of laboratory practice, minimizes equipment misuse, and promotes a stronger occupational safety culture, making it a practical and sustainable model for laboratory management in higher education

Abstract

Rattan is an environmentally friendly alternative material with significant potential for the handicraft industry, particularly in Southeast Sulawesi. However, the rattan splitting process is still predominantly performed manually, resulting in low efficiency, long processing time, and increased occupational safety risks. Therefore, this study aims to design and evaluate the performance of a semi-automatic rattan splitting machine that is efficient, ergonomic, and environmentally sustainable. The research methodology includes the stages of design, manufacturing, assembly, and performance testing . Performance tests were carried out by comparing the splitting time between manual methods and the proposed machine, using rattan diameters ranging from 10 mm to 20 mm. The results indicate that the designed rattan splitting machine significantly improves processing efficiency and production capacity, produces more uniform split results, and reduces material waste. In addition, the machine demonstrates efficient fuel consumption, making it suitable for small- to medium-scale handicraft industries, the proposed machine provides a practical solution to enhance productivity, economic efficiency & environmental sustainability in rattan processing industries
