Abstract
This study aims to analyze waste in the fertilizer production process at PT Magnesium Gosari Internasional using the Lean Six Sigma approach and the 5S method. The types of waste found include defects, motion, transportation, waiting, inventory, overprocessing, and overproduction. DMAIC (Define, Measure, Analyze, Improve, Control) methodology was used to identify root causes and formulate improvement solutions. Data was collected through direct observation, questionnaires, and internal company documentation during the period August 2024 to January 2025. The analysis results show that the most dominant waste is defects, followed by motion and transportation. The initial DPMO (Defects Per Million Opportunities) value was 32,706.67 with a sigma level of 3.43. The initial lead time of the production process was recorded at 350 minutes and was successfully reduced to 305 minutes after the implementation of improvements. The improvement recommendations focused on applying the 5S method (Seiri, Seiton, Seiso, Seiketsu, Shitsuke) to create a more efficient and organized work environment. The application of Lean Six Sigma and 5S is expected to increase process efficiency, reduce defect rates, and increase overall company productivity.
