<![CDATA[General Background Quality control systems play a crucial role in manufacturing environments by systematically identifying product defects and mitigating operational risks. Specific Background Bag manufacturing operations face processing deviations, customer product returns, and time imbalances between planned schedules and actual execution. Knowledge Gap Although Failure Mode and Effects Analysis and cause-and-effect mapping are widely utilized, empirical studies integrating Risk Priority Number calculations with root cause categorization in specialized bag assembly lines remain limited. Aims This study evaluates quality control failures in the bag manufacturing process at PT. XYZ to establish priority corrective actions using Risk Priority Number modeling and root cause analysis. Results Quantitative risk evaluation yields Risk Priority Number values ranging from 36 to 125, with peak operational risks identified in heat pressing during thermal pressing (RPN 125) and quality inspection activities (RPN 112). Novelty Systematic integration of Failure Mode and Effects Analysis with Ishikawa mapping categorizes manufacturing defects across human, machine, material, environmental, and procedural dimensions. Implications Standardizing machine calibration parameters and elevating operator competency through targeted training mitigates defect occurrence and supports long-term product quality. Key Findings Highlights Heat Press Area Generates Highest Risk Priority Number Of 125 Final Quality Control Inspection Represents Second Highest Risk At 112 RPN Multi-Factor Cause Mapping Identifies Human And Machine Parameters As Primary Drivers Keywords Bag Production, Quality Control, Risk Priority Number, Cause And Effect Diagram, Defect Mitigation]]>
