Process industry such as the petrochemical industry is a kind of industry where the production performance depends on production equipment and assets. Thus, maintenance becomes very important way to achieve sustainable production in the process industry. The effectiveness, efficiency, reliability and maintenance of the equipment are vital for the uninterrupted, continuous and efficient operation. Types of preventive maintenance activity applied in the process industry generally are Routine Preventive Maintenance (when the plant is on), Turnaround Maintenance (Shutdown Preventive maintenance), and Inspection. Turnaround maintenance (TAM) plays the most important role of preventive maintenance activities because it is an essential activity of maintenance in the process industry to improve the availability and reliability of the assets includes plant facilities, equipment and machinery. This study evaluates the effect of Turnaround Maintenance applied in the assets to the performance of the plant in the case study company. The significant variables used to analyze the effect of TAM to the availability and reliability of the assets are Plant Availability and Downtime Loss. The statistical method is used to analyze the correlation of TAM occurrence with each variable. The result shows that the correlation value between TAM occurrences with the increasing of availability is 0,315. The correlation value between TAM occurrences with the increasing of downtime loss is -0,818. It can be concluded that TAM activities of the assets have significant effect to increase the availability of the plant, and to decrease the downtime loss. It proves that in the real process industry practice, TAM do improves the availability and reliability of the assets.
