Implementation of Decision Support System for Integrated Coastal Zone Management of Sustainable Mariculture Development Industry in Indonesia

Indonesia has abundant and potential coastal resources for future development of mariculture industry activities. However, complex problem is found in the land and coastal zone utilization, among others: coastal environment degradation, resources depletion, conflict and
overlapping utilization of marine area. New perspective of Decision Support System (DSS) for
integrated coastal zone management (ICZM) can be used to solve this complexity with respect to the results of high resolution of hydrodynamic and wave numerical model, water quality, and ICZM. The aim of this paper is to determine the suitable site for the implementation of sustainable future development of mariculture in Galang Island, Riau Province, Indonesia. A
suitability map of geographic information system based on ICZM is indicated by sixteen
thematic maps. Implementations of the comprehensive ICZM of DSS criteria prove that Galang Island has a bright potential of Grouper mariculture development industry by sustainable suitable area of about 12,940 hectares.
