Analisa Desain Rangka Incinerator Sampah Kapasitas 45 Kg/ Batch Berbasis CAD Menggunakan Metode Finite Element Analysis (FEA)

Abstract

Small-scale waste management requires efficient and safe technologies. This study presents a structural analysis of a 45 kg/batch waste incinerator frame using a Computer-Aided Design (CAD) approach and Finite Element Analysis (FEA) method. The frame is constructed from ASTM A36 hollow steel profiles measuring 40 × 40 × 3 mm. Simulations were carried out to evaluate Von Mises stress, displacement, and safety factor under two loading conditions. The results show a maximum stress of 10.07 MPa, well below the yield strength of 250 MPa. The maximum displacement of 0.0608 mm indicates good structural stiffness. The minimum safety factor is 25, confirming that the design is structurally safe and feasible. This design can serve as an effective and sustainable solution for small-scale waste treatment.
