Abstract

The main objective of this study is to identify and reduce product defects occurring during the production process. Data was collected from January to December 2023, with an initial defect rate of 8.65%, equivalent to 86,500 defects per million opportunities (DPMO). Through the application of the Lean Six Sigma method, the defect rate was successfully reduced to 6.16%, or 61,600 DPMO. The initial Sigma level was 3.82 and increased to 4.10 after improvements. This approach involves several key stages: Define, Measure, Analyze, Improve, and Control (DMAIC). In the Define stage, the problem is clearly defined, including identifying the most frequent types of defects such as cracks, surface blemishes, and size variations. In the Measure stage, data is collected and analyzed to identify problematic areas, using statistical tools like histograms, Pareto charts, and control charts. In the Analyze stage, an in-depth analysis is conducted to find the root causes of defects through methods like the 5 Why's and fishbone diagram. In the Improve stage, solutions are implemented to address the root causes, such as adjusting machine parameters, retraining employees, and enhancing raw material quality. In the Control stage, steps are taken to ensure that the improvements made can be sustained in the long term by implementing regular monitoring procedures and quality audits. Keywords : Lean Six Sigma, Product Defect, Production Process, Quality Product, DMAIC, Floor Tile.

Abstract

PT. AP Tbk. A company engaged in the integrated textile industry, one of the companies that produce various types of high-quality production in yarn manufacturing. Problems that occur at PT. AP Tbk. Superior in yarn processing facilities. In the layout production facility has not been used optimally, location settings are not optimal. found a step back that caused the distance to be far away. For that, it is necessary to restructure the layout of these machines so that the total distance of material handling is faster. Based on the results of research and data processing using a systematic Layout Lay out method, the layout is more efficient when compared to the layout before repair. With the SLP method, two alternative layout locations are produced which can minimize the distance of the material flow and the cost of material handling. Layout 1 can save a distance of 45 meters by issuing material handling costs of 3881.52 rupiah from the initial layout, while layout 2 can save a distance of 57 meters by looking for material handling costs of 4744.08 rupiah from the initial layout. Thus, layout 2 is more recommended so that activities and production results are more optimal and handling of cost material becomes smaller.
