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

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
