Abstract

This study explores the role of operator experience in optimizing main engine cooling systems within large-capacity machinery industries. Using a qualitative case study approach in the heavy manufacturing sector in Banten Province, data were collected through in-depth interviews and on-site observations involving 12 informants, including engine operators, supervisors, and maintenance technicians. Thematic analysis reveals that operator experience is critical for early detection of thermal abnormalities, adaptive adjustment of operating parameters, and prevention of recurring system disturbances that are not fully addressed by standard procedures. The study concludes that systematically integrating operator insights into operation and maintenance management enhances cooling system optimization and offers practical contributions to operational strategies and field-based training in mechanical engineering.
