provides very limited application potential for ill-structured complex community based natural resources management decision problems with strong spatial
component. Using MCA alone would present a real challenge for participants to visualize the spatial dimensions of the decision problem. These limitation can be
overcome by the integration of GIS and MCA.
2.9 The previous research
Spatial Multi Criteria Analysis has ever been applied for the coastal management in Rayong Province Thailand by Joan Looijen, Netatua Pelesikoti and
Marc Staljanssens. The main problem is conflict interest between mangrove forest conservation and the development of shrimp culture in mangroves. The objectives
were to analyze the conflict of interest, to apply suitability assessment, to identify areas of conflict, to formulate policy alternatives, and to compare the alternatives
using different policy schemes. By using Multi Criteria Analysis method the best alternative land use were derived.
The same method will be tested to apply in land coastal of Parangtritis Bantul Yogyakarta. The existing land uses are mainly for tourism and farming. The problem
are different, they are the conflict between sand dune conservation and development of tourisminfrastructure, and utilize of land for paddy field and others. This situation
are challenges on how the use of Spatial Multi Criteria Analysis for land coastal sustainable tourism planning.

3 III GENERAL DESCRIPTION OF THE AREA
3.1 Introduction
The President’s Decree number 22 1999 about regional autonomous give more authorities to the local government. This has impact on the way each local government
to develop their own activities. However, there are negative impacts that need considerations. Many of the local governments have perceived this decree in the
wrong way. Because of the bigger authority they attempt to manage their territory to increase as much regional income as they can, causing uncontrolled resource
exploitation. Bantul Regency is one of the autonomous regions in Yogyakarta that has many
potential resources, dominated by agricultural sector, while tourism is another potential sector that has given contribution in gaining regional income. Parangtritis is
one of the tourism areas in Bantul that has contributed the most income from tourism sector in Bantul.
Nowadays, Parangtritis is characterized by its uncontrolled development and mismanagement; the area has become a slum of tourism resort. The main interesting
parts of Parangtritis tourism object are sandy beach and sand dunes. Unfortunately, the site is also surrounded by hotels, settlement, rest rooms, and unorganized parking lots.
If no special attention to this growing site, there will be deterioration and decrease in tourism value, and may decrease in the number of visitors. Hence, there is a need for a
sustainable development in this area that may benefit for longer term not only for investors, but also for local community and government.
The important factors that should be considered for the development of Parangtritis tourism are the competence for local community, balancing the function
16
of land capability, land capacity and the core of the tourism itself. According to the local government
vision in tourism planning RTOW, 2003, the development should fulfil four principles, these are balanced growth of local socio-economic-cultural condition,
balanced growth of conservation and development spatial principle, good access of public amenities for everyone, and democratic local-based governance system.
