19 is intended to provide coding system which represents the available feature class
in the data. The dataset which transformed by SUITSTAT were land cover and species
distribution dataset. Land cover dataset upon Mt. Salak area was transformed into surface flat polygon and species distribution data was buffered. Surface flat
polygon dataset vector-based grid was made to represent the area of which its suitability being investigated. Species distribution data was buffered in rectangle
shape which represents the homerange of javan gibbon about 16.7 Ha based on Kappeler, 1984. The work flow of data preparation is shown in the Figure 3.

3.3. Time and Location
The study was started in September 2005 to December 2006. The field survey was done in December 2005, January to February 2006 and May to June
2006 at several places in Mt. Salak, West Java. Most of time was spent to develop this application in GISRS Laboratorium in MIT-Biotrop.

IV. RESULTS AND DISCUSSION
This chapter consists of two major sections. The first section exposes the result of SUITSTAT system development, javan gibbon field survey and habitat
suitability model. The last section is the discussion on the performance of the system, javan gibbon distribution and habitat suitability analysis in Mt. Salak.
4.1. System Development Result
The development process of SUITSTAT is following iterative and incremental approach, where system functionality is developed through iterative
process. The process of the development is described in the series order as it could be easier to understand by the reader, that is requirement analysis, system
analysis and design, and system testing.
4.1.1. Requirement Analysis
The elements of system requirement are identified by analyzing the need, data and information, and user of the system which described in the next
subsection. The synthesis of these elements is described in the last subsection followed by the proposed conceptual system.
4.1.1.1. Need Analysis
National park management is managed by zonation system Republic of Indonesia, 1998. In developing park zonation, the information on wildlife
distribution and their habitat condition should be considered, including habitat suitability.
In Mt. Halimun Salak National Park, the information of habitat suitability is not available or provided at once. In addition, this issue is relatively new and its
study in the Indonesia is rare. In contrast with the developed country which the methods and techniques has been evaluated. Because of that, park staff is not
familiar with the method and procedure to produce habitat suitability.
