General Background: Productivity and machine effectiveness are critical factors in manufacturing systems to ensure product quality and operational efficiency. Specific Background: In PVC pipe production, machine downtime and performance issues often reduce overall productivity levels. Knowledge Gap: Limited integration of Overall Equipment Effectiveness and Failure Mode and Effect Analysis is applied to identify root causes and prioritize improvements in machine performance. Aims: This study aims to evaluate machine productivity using OEE and determine improvement priorities using FMEA in a PVC pipe production process. Results: The analysis shows an average availability of 91%, performance rate of 80%, and quality rate of 93%, resulting in an OEE value of 68%, which is below the ideal standard of 85%. The main causes of low effectiveness are related to downtime factors such as pipe defects, machine instability, and operator-related issues. FMEA analysis identifies priority improvements with the highest Risk Priority Number of 648, followed by 392 and 378. Novelty: The study combines OEE and FMEA to provide a structured evaluation of machine productivity and prioritized corrective actions. Implications: The findings offer practical guidance for improving machine performance and reducing downtime in manufacturing operations.
