Indonesian Shipbuilding Industry in the perspective of Collaborative Manufacturing Network (CMN)

The Indonesian shipbuilding industry must get involved in a collaboration network in order to be survived in the global competitiveness. The competitiveness level of Indonesian shipbuilding industry is low with only about 1.6 percent of International market share. Most of the proportion is contributed by PT PAL Indonesia with its maximum 50.000 DWT of shipbuilding capacities. The reason can be identified as the Indonesian domestic shipyards are still working as a single company respectively. This fact is contradicted with the tendency of international shipbuilding industry in the current global competitiveness to do collaboration among them to increase their production capacities. Successful example of the shipyard collaboration in order to get the most of the shipbuilding international market is collaboration among shipyards in South Korea and China. Both of these countries have integrated their shipyards and hence have increased significantly their shipbuilding production capacities. Currently, they have been recognized as a shipbuilder country. This paper discuss the condition of Indonesian shipbuilding industry and the potency to get involved in a collaborative manufacturing network in order to increase its global competitiveness

Conceptual Model for Transfer of Technology in a Shipyard

Transfer of technology is an important program to be done by a shipyard if the respective shipyard is to maintain and increase its competitiveness. But sometimes, some aspects that need to be considered in a transfer of technology program are ignored. Before any transfer of technology program is to be conducted in any shipyard, identification of the required technology to be transferred and why the changes in shipyard technology are needed must be done. These identifications will lead to the identification of the current shipyard competitiveness and the identification of the shipyard hardware and software technology components performances. Decision will be made which is based on these identifications. If the software technology components show good performances, then maximum advantages will be obtained from the current facilities and any investment in hardware technology components will tend to reduce the cost per unit of output. On the contrary, if the software technology components show bad performances, then any investment in hardware technology components will tend to increase the cost per unit of output. In this paper, a conceptual model of transfer of technology in a shipyard is developed. The proposed model is expected to be a reference model for a shipyard practitioners when a transfer of technology program is about to be conducted and hence prevent losses of investment mistake and obtain maximum advantages from the transfer of technology process

Initial Model Development of an Integrated Shipbuilding Industry in Indonesia: a Case Study of Indonesian State Owned Enterprises (BUMN) Shipyards

Capacities of the world shipbuilding industry have been dominated by three major countries which are South Korea, China and Japan. The ship tonnage proportion they have been built is approximately 90% of the total ship tonnage in the world. Indonesia with the rest of the shipbuilding countries only share the rest of the proportion which are far less than the total capacities of those three countries. Indonesia has its potency to increase its shipbuilding industry capacity significantly with the support of 250 shipyards in this country. The increasing capacities can be fulfilled if those shipyards are getting involved in collaboration. The increasing capacity of Indonesian shipyard is need to be actualized to prevent order of shipbuilding rejection from overseas as a consequence of shipyard insufficient capacity. In this paper, an initial model for shipyard collaboration in Indonesia is developed. The number of shipyards to get involved in this initial model is limited to 4 BUMN shipyards. The selection of those shipyards is based on the consideration that those shipyards are under central coordination of Indonesian BUMN Ministry. Some aspects related to the model development are discussed and in the end, an initial model of an integrated shipbuilding industry in Indonesia is proposed
