Abstract
PT Kilang Pertamina Internasional Refinery Unit VI is one of Indonesian State-Owned Enterprise that focuses on the refinery and petrochemical sector. The nitrogen plant is one of the main production unit at Refinery Unit VI. There is deviation between total nitrogen requirement with nitrogen production at Refinery Unit VI that has impact in a nitrogen supply shortage which can interrupt of the production process at Refinery Unit VI.
The objective of the study is to solve the problem of nitrogen supply shortage at Refinery Unit VI, so that the continuity of nitrogen supply and fulfillment of stock security can be achieved to support the business continuity at Refinery Unit VI. The root cause analysis method is used to identify the cause of business problems structurally and comprehensively by using several method approaches consisting of Kepner-Tregoe Problem Analysis and Fault Tree Analysis. The Analytic Hierarchy Process method is used to select the best solution from several alternative solutions obtained from the brainstorming stage with several experts. There are three long term alternative solutions consisting of (1)Repair existing nitrogen plant, (2)Build new nitrogen plant, (3)Purchase Nitrogen from an external vendor.
The final stage of this study is to make strategy and plan from the best-selected solution to solve the nitrogen supply shortage at Refinery Unit VI, so that the best solution can be implemented appropriately based on time, cost, quality, and safety aspects. The project implementation plan includes three main scopes consisting of processes, people, and tools aspects.
