Enhancing Manufacturing Efficiency at Telkom University: Advanced Automation of Bucket Conveyor and Hammer Mill Machine with PLC and HMI Through the Waterfall Method

Abstract

The abstract presents a study on the enhancement of manufacturing technology at Telkom University, specificallyaimed at improving the production of raw materials for charcoal briquettes and animal feed. Initially hindered by a lackof a sophisticated monitoring and control system, the existing production relied heavily on manual time calculations, leading to high risk of inaccuracies and errors. To address this, the study proposes a novel redesign of the control system for the hammer mill machine, particularly in the panel section, using the waterfall design methodology. Thisstrategic redesign has led to the implementation of an advanced automation system, which significantly streamlines the process by automatically displaying time and power consumption data on the HMI display. This enhancement notonly simplifies monitoring and control, but also substantially boosts efficiency. The results show a reduction in thehammer mill machine's operating time by 13 seconds, an increase in productivity by 48%, and reveal powerconsumption details for the motor and conveyor bucket. These results demonstrate the efficacy of the redesignedsystem in enhancing operational efficiency and monitoring precision in the manufacturing process.
