Abstract

A composite is a material structure composed of two or more combinations of constituents combined macroscopically, where the two combinations do not dissolve each other. The first phase is called reinforcement, while the second phase is called matrix. This study aims to analysis the tensile and bending strength values of coconut fiber reinforced composites with a sequence of layers of quasi-isotropic fiber laminates. Experimental studies were carried out on polyester resin composites reinforced with coconut fiber in the fiber layer sequences of [0°/0°/0°], [+45°/0°/-45°] and [+60°/0°/-60°]. Tensile test specimen standards refer to ASTM D-3039 and bending test standards refer to ASTM D-7264. The results of the blistering test obtained a maximum stress of 18.3298 N/mm2 in the fiber layer sequence [0°/0°/0°] and a minimum stress of 10.8966 N/mm2 in the fiber layer sequence [+60°/0°/ -60°]. Meanwhile, the bending test results showed that the maximum bending stress was 76.065 N/mm2 in the fiber layer sequence [0°/0°/0°] and the minimum stress was 30.256 N/mm2 in the fiber layer sequence [+45°/0°/-45 °].

Abstract

Proses pengayakan pasir secara manual di industri konstruksi memiliki produktivitas rendah dan hasil yang tidak konsisten. Penelitian ini bertujuan untuk merancang belt konveyor mesin pengayak pasir tipe rotary dan menganalisis kekuatan struktural rangka menggunakan material aluminium 6061-T6. Metode penelitian meliputi perhitungan manual menggunakan teori mekanika teknik dan simulasi Finite Element Analysis (FEA) dengan software Autodesk Inventor 2020. Parameter yang dianalisis mencakup tegangan maksimum, regangan, displacement, dan faktor keamanan pada rangka mesin dengan beban operasi 4,165 N. Hasil perhitungan manual menunjukkan tegangan maksimum 71,126 MPa, regangan 0,001032, displacement 0,1912 mm, dan faktor keamanan 3,866. Hasil simulasi Autodesk Inventor memberikan tegangan maksimum 52,16 MPa, regangan 0,000635, displacement 0,4068 mm, dan faktor keamanan 5,272. Kedua metode menunjukkan deviasi 26,7% yang masih dalam rentang dapat diterima dan mengkonfirmasi bahwa rangka aman dengan faktor keamanan >3. Mesin yang dirancang mampu mengangkut dan menyaring pasir dengan kapasitas 5,7 ton/jam menggunakan motor listrik 2 HP, meningkatkan produktivitas 11-19 kali lipat dibandingkan metode manual (0,3-0,5 ton/jam). Kecepatan belt optimal 0,5 m/s dengan efisiensi pengayakan 92%. Desain ini telah tervalidasi dan siap untuk fabrikasi prototype.

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
