<![CDATA[Manual coffee cherry sorting has limitations in terms of capacity, consistency, and efficiency, making it necessary to develop a sorting machine with a strong, safe, corrosion-resistant, and cost-effective structure. This study aims to design the frame of a coffee cherry sorting machine and determine the most suitable materials for the frame and hopper through static structural simulation. The design was developed using SolidWorks, while the structural analysis was conducted using SolidWorks Simulation based on the Finite Element Analysis (FEA) method to evaluate the von Mises stress, displacement, and Factor of Safety (FOS). The simulation results indicate that Galvanized Steel is the most suitable material for the machine frame, as it provides safe structural performance with maximum stress below the material’s yield strength, low displacement, and Factor of Safety that satisfies engineering safety requirement. In addition, Galvanized Steel offers better corrosion resistance and material cost efficiency than the other evaluated materials. For the hopper, Stainless Steel 201 demonstrated the best performance, achieving an excellent structural strength and corrosion resistance for coffee cherry handling applications. Based on the static simulation and cost analysis, Galvanized Steel is recommended as the frame material, while Stainless Steel 201 is recommended as the hopper material because they provide the best balance of structural strength, safety, corrosion resistance, and cost efficiency]]>
