Abstract

This study was motivated by the lengthy processing time in the bus seat molding production process at PT. XYZ, which affects manufacturing efficiency. The objective of this research is to identify the activities that contribute most significantly to production time and to analyze the factors causing process delays. The research employs the Pareto Diagram to determine the activities with the greatest contribution to total production time and the Fishbone Diagram to identify the root causes of the problem based on six aspects: human, machine, method, material, environment, and measurement. The results indicate that material mixing, curing, material weighing, and foam injection are the four main activities contributing to more than 80% of the total production time. The Fishbone analysis reveals that insufficient operator training, non-standardized work procedures, material instability, machine disturbances, unfavorable working conditions, and the lack of standardized measurement systems are the primary causes of prolonged production time. The study concludes that the combined application of the Pareto and Fishbone Diagrams is effective in identifying improvement priorities to enhance production time efficiency through the standardization of work procedures, improvement of operator competencies, and regular machine maintenance.
