I. INTRODUCTION
1.1 Background
As an archipelagic state, Indonesia is one of the biggest areas in the world. The seaboard of Indonesia has a unique ecosystem of coral reef, seaweed and fish
around coral. Therefore, the coastal area has a unique problem to be solved. This study emphasizes on coastal marine, spatial analysis of the coastal area used
available data, in such a way that can get recommendation output for coastal marine cultivation. The development of the coastal marine considered custom of
local population which could assist the local government in preparing the development planning. It also provides an alternative source of information that
can be used for all needs such as for the development of industrial sector, economic, and human resources.
Generally, spatial decision making means “closed” process with limited parameter input to get a better output Malczewski, 1999. These days some spatial
decisions have been made by people as planners who work for the government with less real specification, while it claimed that decision-making reflected public
needs and also claimed as public opinion. The last decade with the rapid change of environment planning also change spatial decision-making with more demands
and needs. Recently, environment development for spatial decision-making involves public collaboration and participation to get more effective solutions to
spatial decision-making problems. Because the complexity of problem in coastal area, decision making is needed to
take benefit for cultivation, and use integration of multi-criteria decision analysis MCDA as a comprehensive decision support in geographical information system
GIS. This MCDA provided effective decision that can handle spatial and non spatial databases. The information in its eventual allows for the spatial and non
spatial datasets organization, analysis and transformation to obtain the required information.
2 Synergy of GIS and MCDA is used to dealing with spatial planning. And the
process can mean that the transformation process on the map that will be assessed and combined with the assessment of the decision maker to produce accurate
information Malczewski, 2006. The implements of GIS-MCDA also used the assessment of a specialist reference group expert that has been identified as a
basic reference. The GIS-MCDA system could solve the potential problem with the approach of communication in building communication with stakeholders. In
addition, tools to the implementation to solve an occurring issue are also used. The overall system that will be developed assembles information on the
importance of many variables of coastal marine. Other advantages used MCDA as management data so that it could expect output information, and update easily.
This information is useful for the local community who lives in and around the coastal area to be involved in coastal development and conservation and to
understand the environmental problems of coastal marine. Thus, special problems could be identified, compared with coastal marine globally to show which coastal
areas may share common problems and the possibility to cooperate in solving those problems.
Saleh gulf, as one of the coastal area in Sumbawa Island, has also a threat such as exploitation that can lead to environmental and natural resources degradation of
the coastal area if not managed properly. The coastal zone has a coastline length of 79.6 kilometers, and the total area is about 20 153.15 km

. The facts in Sumbawa coastal region appeal to development of various activities.
