Analisys detection place defect incoming part in the incoming quality control division at PT XYZ cikarang

Abstract

The quality of incoming parts is a critical factor affecting the quality of final products in the electronics manufacturing industry. Nonconforming materials received from suppliers can increase product defects, production costs, and disrupt manufacturing processes. This study aims to analyze incoming part defects in the Incoming Quality Control (IQC) Division of PT XYZ Cikarang based on defect types, defect detection locations, root causes, and improvement priorities. The study employed Seven Tools, Fishbone Diagram, and Failure Mode and Effect Analysis (FMEA) using data from the Incoming Production Rework Report for February 2026. The data were analyzed using check sheets, Pareto diagrams, defect detection place analysis, Fishbone diagrams, and FMEA. The results revealed that scratch was the dominant defect, accounting for 58.66% of the 358 recorded defects, while the highest-risk failure cause was the non-optimal material handling standard operating procedure, with a Risk Priority Number (RPN) of 504. Based on these findings, improvement priorities were focused on revising material handling procedures, enhancing operator competency, standardizing supplier packing methods, and improving material storage systems. This study contributes by integrating Seven Tools, Fishbone Diagram, and FMEA to establish a systematic risk-based approach for prioritizing quality improvement actions, thereby supporting more effective incoming material quality control in electronics manufacturing
