ABSTRACT

Javan gibbon (Hylobates moloch Audebert 1797) is an endemic primate found only in the western and central parts of Java. According to the 2009 IUCN Red List of Threatened animal, this species is catogorized as endangered species. Javan gibbon’s habitat is restriced to floristically rich patches of relatively undisturbed lowland rain forest to low mountain rain forest mostly below 1,600 m asl found currently only in forest remnants. At present the original forest remains was decreasing. A large population javan gibbon remark in Ujung Kulon National Park (UKNP), unfortunatelly forest degradation were happened mostly in Gunung Honje area. The objectives of this research is to estimate the extent of suitability habitat, produce information characteristic, and classifield similarity habitat of Javan gibbon in Gunung Honje UKNP. This study was carried out in Gunung Honje area and Kalejetan resort UKNP on Desember 2009 to Februari 2010. Digital environmental layers such as elevation, slope, aspect, and especially vegetation type may be incorporated into predicted habitat suitability. Principal Component Analysis method on SPSS17 was used to analysed suitability habitat, mapped with ERDAS Imagine 8.6 and ArcView 3.3. Based on scoring and spatial analysis, the estimation of habitat with low suitability is about 1.760,53 ha, habitat with moderrate suitability is about 6.581,39 ha and habitat with high suitability is about 8.342,85 ha. The model validation achieve 95,45% for high siutability habitat.
