Abstract

Indonesia has a great potential for developing the mariculture industry. However, during the operation faced a lot of problems due to hydrodynamic environment engineering fields. The main case was the misplaced location of the mariculture development with respect to the weak sea current in the vicinity area. Meanwhile, the accomplishment of sustainable practices and management systems to preserve coastal environments is still in its infancy. Therefore, it is vital to improve aquaculture technology and to develop management tools. This problem can be determined by an implementation of the numeric mathematical model of the sea current flow which illustrates the physical process of domain area. At this manuscript, the assessment utilized 2-dimensional numerical models in Decision Support System (DSS) at the Ekas Bay, Lombok Indonesia. Simulations were carried out by applying the open source of Delft3D modeling system which was fully integrated with modeling framework for the simulation, among others of flow and waves. The outcomes prove that hydrodynamic model can be used as an initial assessment for decision maker for future development of sustainable mariculture industry in Indonesia.
