<![CDATA[Drum packaging quality is essential to prevent leakage, contamination, product damage, and distribution safety problems in paint and resin manufacturing. This study aims to evaluate the capability of the measurement system used in drum packaging inspection using Gage Repeatability and Reproducibility. The inspection output was treated as variable data, represented by the defect proportion obtained from drum packaging inspection results. Data were collected from 20 shipment inspections involving four operators and two repeated measurements. The analysis evaluated repeatability, reproducibility, total measurement system variation, and the Precision-to-Tolerance ratio. The results showed that repeatability variation was 0.016, while reproducibility variation was 0.001, indicating that within-operator variation was higher than between-operator variation. The combined measurement system variance was 0.000272, with a corresponding standard deviation of approximately 0.016. The P/T ratio was 0.0048, which is below the commonly accepted threshold of 0.10 for an acceptable measurement system. These findings indicate that the drum packaging inspection system is reliable and capable of producing consistent inspection results. Practically, the results support the use of standardized inspection procedures to maintain operator consistency and improve packaging quality control.
