Time and Location METHODOLOGY

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. Figure 3. Data Preparation Work Flow

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. at t r ibut e adj ust m ent DEM count ur landcover rivers road forest ext ract ion elevat ion class slope class SUI TSTAT syst em set t lem ent forest t ype forest ecosy st em Species dist ribut ion 20

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.
