Javan gibbon is an endemic species in West Java and it is categorized as endangered species now (IUCN, 2008). Javan gibbon habitat is sentralized in lowland forest and mountain forest, one of that are situated at Gunung Tilu Protected Area.
However the area has been facing many problems which resulted from human activites such as stealing the forest products, and the existence of tea plantation in this protected area. The research objectives is to develop the habitat suitability map of Javan gibbon in Gunung Tilu Protected Area (GTPA) utilizing Geographic Information System
Javan gibbon habitat suitability mapping was initiated by collection the spatial and attribute data, such as digital map, data survey, and literature. This mapping was based on some habitat variable which determine the Javan gibbon habitat suitability, namely Leaf Area Index (LAI), accesibility (elevation and slope), and distance to road.
Variables then were analyzed with GIS and produced thematic map for each variable.
Javan gibbon distribution survey data in GTPA by KONUS (Konservasi Alam
Nusantara) was used for determine the weight value of habitat variable using a
Principal Componenet Analysis (PCA). Result of PCA were utilized as weight to determine Javan gibbon habitat suitability model. Furthermore, the model analyzed by using scoring and overlay methode.
Result and disscussion
The habitat suitability model: IKH = (2,154xFLAI) + (2,154xFjalan) +
(1,044xFtinggi) + (1,044xFlereng). The habitat suitability map were reclassified into three suitability class. The result showed that there were 10263, 125 hectares of low suitability habitat (suitability value 2,088-7,1081), 6197,3125 hectares of medium suitability habitat (7,1081-14,2162), 8538,5625 hectares of high habitat suitability
The area of high habitat suitability sentralized in south and northeast area of the model. Based on the model, the influential habitat variable are LAI and distance from road. The model validation achieve 87,5% for high suitability habitat.
