Abstract

This article presents an improvement in the efficiency of a rubber sheet rolling machine using a three-phase inverter and evaluates its economic feasibility to support practical adoption by small-scale rubber farmers. The experimental results indicate that the improved machine achieves higher energy efficiency, leading to energy savings of 66.5% under no-load conditions and 64.57% under load conditions. This allows rubber farmers to reduce electricity costs by 48.22% in the rubber sheet production process. Additionally, the findings suggest that a roller speed of 51 RPM minimizes rubber sheet tearing during rolling and ensures uniform sheet thickness, meeting the Grade 1 rubber sheet standard. This enhancement enables farmers to sell rubber sheets at a higher price.
