Abstract

The increasing volume of beverage can waste in Palembang City requires effective handling to optimize storage space before the recycling process, such as through the use of a mechanical press tool. This study aims to document and reconstruct the design of a double-lever manual can press, verify structural strength through mechanical engineering approaches, and empirically evaluate the tool's performance. A re-engineering method and CAD modeling were employed to obtain as-built technical specifications, with a lever arm ratio of 380 mm : 95 mm (a 4:1 ratio). Static structural analysis indicates that an input force of 200 N from the operator generates an effective pressing force of 800 N, with a shear stress on the hinge pin of 10.19 MPa and a weld joint stress of 9.43 MPa, resulting in a Factor of Safety (SF) of greater than 3 (safe). Empirical performance testing was conducted using aluminum can samples with capacities of 250 ml (sleek type) and 320 ml (standard type). The results show that the tool possesses excellent volume reduction efficiency, with an average shrinkage percentage reaching 90.90% for 250 ml sleek cans and 88.60% for 320 ml standard cans, with operation times ranging from 3.90 to 4.40 seconds. Differences in geometry and material ductility influence the ease of deformation, where the sleeker cans deform more effectively under axial compression. Overall, the reconstructed tool is proven to be reliable, structurally safe, and effective in increasing the productivity of can waste compaction for collectors. Keywords: Design Reconstruction, Manual Can Press Tool, Engineering Mechanics, Waste Volume Reduction.
