Abstract

This study aims to analyze the musculoskeletal disorders (MSDs) risk of workers at PT Kanugrahan Techno Engineering involved in grinding activities using the REBA (Rapid Entire Body Assessment) method. The analysis results indicate that grinding activities 1 and 2 have a REBA score of 9, indicating a very high risk, while grinding activity 3 has the highest score of 10, indicating an extreme risk. Grinding activities 4 and 5 have a score of 7, indicating a moderate risk. To reduce these risks, ergonomic aids in the form of a table and chair were designed to support better posture. The production cost of one set of tools is Rp 710,966, with a total cost for 5 sets amounting to Rp 3,554,833.91. The implementation of ergonomic aids is expected to reduce MSDs risks, increase comfort and work efficiency, and improve worker productivity.

Abstract

Product quality is a key factor in enhancing a company's competitiveness. PT Nugraha Potong Tekuk, a producer of MPGG products, experienced a significant increase in the defect rate, reaching 11% of total production during the period from June 24 to July 16, 2024. This study aims to analyze the defect rate, identify the main causes, and provide improvement recommendations. The study follows the Six Sigma methodology, including the Define, Measure, Analyze, Improve, and Control (DMAIC) phases. Based on P-Chart analysis, the production process is within statistical control limits, but the defect rate still requires improvement. Two main types of defects were identified: unevenness and size defects, each accounting for 50% of the total defects. Fishbone diagram analysis revealed four main contributing factors: people, machines, materials, and environment. The people factor includes lack of operator skills and operator fatigue, while the machine factor covers worn-out tools and uncalibrated measuring instruments. The material factor is related to low-quality raw materials, and the environmental factor includes poor lighting and unstable work surfaces. Improvement recommendations include operator training, routine machine maintenance, quality control of raw materials, and improvement of the work environment. This study is expected to help PT Nugraha Potong Tekuk enhance product quality, reduce defect rates, and maintain competitiveness in the market.
