Abstract

MSMEs are one of the main pillars of Indonesia's economic growth, especially in the food sector. However, many production processes are still carried out manually and are not ergonomic. One such example is Mrs. Hj. Handayani's tofu MSME, where the manual tofu cutting process causes a non-ideal working posture and risks causing Musculoskeletal Disorders (MSDs). This study aims to initiate posture work using the Nordic Body Map (NBM) and Rapid Upper Limb Assessment (RULA) methods, as well as designing an ergonomic cutting tool based on a pneumatic system adapted to local anthropometric data. The evaluation was conducted on one worker through direct observation and body angle analysis using Angulus and CATIA V5 software. The initial analysis results showed an NBM score of 57 and a RULA score of 6, indicating the need for work posture improvements in the near future. After the implementation of the tool, the RULA score decreased to 2 and cutting time was reduced by 45%, proving the tool's effectiveness in improving ergonomics and work productivity in the MSME environment.

Abstract

This study aims to optimize distribution routes for Micro, Small, and Medium Enterprises (MSMEs) engaged in the production of premium ice crystals. The Nearest Neighbor (NN) method is used to find the initial route by selecting the closest locations in sequence, while Local Search is used to improve the route found by searching for better local solutions through exchange or improvement of the delivery sequence. The testing was conducted using distribution data from several customers and delivery locations. The research results show that the distribution route for UMKM Es Kristal Premium, when applying the Nearest Neighbor and Local Search methods, resulted in a reduction in delivery distance from 40.3 km to 3.74 km, with a savings of 16.28% for the urban area, and from 52.5 km to 33.1 km for the Limboto-Telaga area, with a savings of 36.95%. Additionally, this method also reduces transportation costs, with initial transportation costs of Rp. 100,000.00 decreasing to Rp. 66,840.00, representing a cost reduction of 33.16%. This method can optimize time and operational cost savings, which can have a positive impact on UMKM Es Kristal Premium in enhancing their competitiveness and service to customers.

Abstract

PT KJI is a manufacturing company engaged in the production of car radiators. The quality of the products is the main focus to meet customer standards. The company faces a high Defect rate that exceeds the tolerance limit of 3%, affecting both process efficiency and customer satisfaction. This study aims to identify the root causes of product defects, calculate the sigma level, and design improvements to reduce the defect rate. The Six Sigma method with a DMAIC approach is used to analyse and control the quality of the production process, supported by the application of acceptance sampling based on AQL standards. The analysis covers the production process, inspection systems, and machine maintenance conditions. It was found that the lack of inspection on incoming materials and finished products, as well as irregular maintenance schedules, are the main factors contributing to the high defect rate. Proposed improvements include enhancing inspections of incoming and outgoing products according to AQL and implementing a more consistent machine maintenance schedule. After the implementation of the proposed improvements, there was a significant reduction in the number of Cacative products. The average sigma level increased from 3.8 to 4.7. This improvement had a positive impact on product quality, production process efficiency, and the reliability of the quality control system at PT KJI.
