Abstract
PT Pertamina (Persero) as the main contributor for LPG supply and distribution in Indonesia relies on the VLGC (Very Large Gas Capacity) for upstream transportation mode. All upstream activities are happened at Teluk Semangka Port, which is the main terminal for import supply and regional distribution throughout Java and Sumatra. The complexity in scheduling VLGC caused time consuming and high cost (demurrage cost and charter cost). Current report stated that through 2007 until 2013, there is a significant demurrage cost increased. This condition can jeopardized the supply and distribution process because of large budget allocation for covering the demurrage cost along with VLGC charter cost. A Decision Support System (DSS) is developed to generate schedule for each operated VLGC that both save time and gives the user recommendation in reducing cost. Several factors are considered in designing the DSS, such as lifting prioritization, demurrage cost, charter cost, and VLGC utilization. Besides its ability to generate complex schedule, an easy to use interface is designed for user to interact with the DSS. From several trials using real data taken from company database, it resulted five operated VLGCs as the best number of VLGCs to be operated. Therefore, it can be a recommendation for deciding the number of operated VLGCs in the following year.
