Vessel Selection to Support Coal-Fired Power Plant Supply Using Multi Criteria Analysis

Coal supplied for power plant located in Pacitan, East Java, is of South Kalimantan and West Sumatera origin and transported mainly through Java Sea using several types of vessel. This supply is very important for securing whole year electricity production. This mostly depends on sea and weather conditions which limit vessels operation pattern. However, costs are the only factor used when selecting the appropriate vessel. In fact, there are several other factors that may influence vessel performance. When these factors are considered, selecting the appropriate vessel is difficult because of complex interaction between them. For such circumstances, a multi-criteria evaluation analysis is appropriate. The aim of this paper is to develop an evaluation and decision-making model based on a multi-criteria evaluation analysis to select an appropriate type of vessel for transporting coal. The model will integrate several independent items and combine them before making a decision. Several types of vessel will be selected and several important aspects contributing to vessel performance will be selected and identified. Results from previous study will be used as a comparison.

Study of Port Tariff Structure and Port Pricing Approach

In order to support National Logistics System continuity there are at least three (3) main components that should synergize well, namely the sea side (sea transport), the land side (hinterland transport) and the part that connects between the two (port). Port performance will greatly affect the performance of the national logistics system as a whole. One of the indicator of a countrys logistics performance evaluation is the ease of arranging shipments of goods at competitive prices (shipment). One of the components of logistics costs which become concern of many parties is the port costs, in order to support the national high logistics cost reduction, study related to the port tariff structure and its associated regulations is needed, especially a matter to formulate and determining policy related to pricing port services. The survey and analysis will be carried out in an attempt to identified the port tariff structure as basis to determining the port pricing model. Port tariff structure analysis include the Identification of port services and cost component (user and port operator point of view). Based on the analysis of transport logistics cost, the shipping cost contribute 48%, port cost 40% and hinterland cost 12%. The port cost on the container terminal, the stevedoring costs contribute 42%, followed by the cargodoring cost 58%. It takes further analysis for stevedoring tariff and tariff lift-on / lift-off container given a large contribution to the overall cost of loading and unloading at the port. Port pricing formulation problem associated with cost (competitiveness), performance (level of services) and value added (value added to the customer), so that the best approach for determinining port cost and tariff are: (1) the first best pricing approach is MC = MR = P, (2) the second best pricing approach is LRMC. We suggest that the pricing policy for ports where tariff formulation needs to consider the external factors (currency, rates, fuel price, minimum salary and etc) and differentiated based on the level of port service. Relevant quality level of port service factors are the time in port, and the punctuality of handling the vessel and its cargo. Port Tariff = f (Cost of Goods Manufactured (production unit cost), Margin, Level of Service (LS)) and Maximum Port Tariff = 1.25 % ofproduction unit cost .
