This study was structured using quantitative methods with a causal research design that states a cause-and-effect relationship. The analysis technique in this study uses Pareto diagrams, FMEA and causal diagram as problem solving tools. The results of the study show that the cause of uneven lamination in the extrusion lamination process at PT X is caused by the lack of human resource capabilities, poor quality control systems, and poorly maintained machines.
