Abstract

PT Global Rising Technologies Perkasa is a contractor engaged in the assembly of high-end wire and cable, as well as box build assembly for the automotive, semi-conductor and medical industries globally. One of the machines used, namely the pneumatic crimping machine, does not operate effectively in its production process. Continuous use of pneumatic crimping machines if not maintained properly causes damage and downtime to the machine. Downtime data that occurred on pneumatic crimping machines from July 2023 to June 2024 was 340 hours. The purpose of this study was to find the factors that cause pneumatic crimping machines to experience high downtime and find ways to reduce it. The analysis method used to measure machine effectiveness is overall equipment effectiveness (OEE), identifying the Six Big Losses using a Pareto diagram, and analyzing the main causes using a Fishbone Diagram. The results of this study show that the average OEE value of pneumatic crimping machines is 67%, far from the international standard of 85%, so it is considered low. The main factors causing high downtime are Equipment Failure Losses of 13% and Idling Minor Stoppages of 22%. There are two pillars of Total Productive Maintenance (TPM) used as a solution, Planned Maintenance and Autonomous Maintenance. With this implementation, the level of operational effectiveness will increase and downtime caused by damage to the pneumatic crimping machine will be reduced.

Abstract

This study aims to analyze the quality control of tempeh chips products in Batam using the Failure Mode and Effect Analysis (FMEA) and Root Cause Analysis (RCA) approaches. Tempeh chips are processed food products that have significant economic value for MSMEs in Batam, but often face various challenges related to quality control. The research method used is a combined qualitative and quantitative approach with a sample of 3 MSMEs producing tempeh chips in Batam. The results of the study identified several major quality problems in the tempeh chips production process, including non-uniform thickness, damaged packaging, soft texture, imperfect packaging seals, and weight contents that do not match the label. Through the application of FMEA, this study calculates the Risk Priority Number (RPN) for each failure mode, identifying five critical problems with the highest RPN values. Furthermore, using RCA and 5-Why analysis so that the root cause of each problem can be identified based on human, machine, method, material, and environmental factors. Based on the results of the analysis, this study recommends a series of comprehensive quality control recommendations, including the development of Standard Operating Procedures (SOPs), quality monitoring systems, employee training programs, and the implementation of quality control checkpoints. This research provides a significant contribution to the development of the tempeh chips industry in Batam and can be a reference for similar research in other areas.
