Abstract

The manufacturing industry in Indonesia, particularly the bag production sector within the textile industry, is encountering significant challenges amidst fluctuating global market conditions. According to data from Badan Pusat Statistik (BPS), the national textile export volume for the first half of 2023 experienced a 13% decline compared to the same period in 2022, reflecting the adverse effects of global demand fluctuations and economic instability. Under these circumstances, optimizing production line performance is critical to sustaining competitiveness in an increasingly challenging market environment. One company grappling with these issues is CV Andespuma Anugrah Pratama, a producer of various polyester-based bags. This research aims to evaluate and enhance the performance of the production line at CV Andespuma Anugrah Pratama by employing the principles of motion economy, 5S methodology, and line balancing techniques. The work system improvement process focused on minimizing non-value-added work elements and improving workplace organization through the 5S methodology. Prior to the interventions, the total cycle time was recorded at 4205,9167 seconds, with an efficiency rate of 61.64%. Following the implementation of improvements, the cycle time was reduced to 3053 seconds. The line balancing analysis utilized the Largest Candidate Rule (LCR), Kilbridge and Weston Method (KWM), and Ranked Positional Weight (RPW) techniques. The results demonstrated that the LCR method improved efficiency to 88.71%, the RPW method achieved 90.30%, while the KWM method yielded the most favorable outcomes, with two alternatives achieving efficiencies of 93.09% and 94.40%. The application of motion economy principles, 5S methodology, and line balancing significantly improved production efficiency at CV Andespuma Anugrah Pratama, with the highest efficiency of 94.40% attained through the KWM method.
