Thejavangibbon (Bylabates moloch) is endemic to Java Island, especially in the western of Java, and it is one of the protected fauna in Indonesia. The exsistence .of javan gibbons have been threatened by poaching and habitat destruction..Thejavan gibbon last habitat might be left only in conservation areas, suchas Taman Nasional GunungGede Pangrango (TNGP). Based on the Fauna Distributio~ Map ofGede Pangrango National Park, Resort Bodogol.was chosen for the sample area. Line transects method was used for studying the distribution ofjavangibbons in Resort Bodogol, by following the research line, up to altitude 1,350. m a.s.lThe existence ofthe javan gibbon is known botll directly and inderictly by direct seeing and vocal .triangulation respectively. The result used for completing the fonnerofdistribution map. Two groups ofthejavan gibbons, was chosen for stuqying the home range, food trees, and sleeping trees. This was achieved by following their daily activities for 10 days each groups. The habitat characteristics based on the distribution ofjavan gibbon which plotted in the various maps. GIS·was used for modeling habitat suitability by overlapping· the various maps which represented the javan gibbon habitatcharacteristics. ~ The result ofobservation showed that the estimation home range area of the groups were 10.233 ha and 15.733 ha. The gibbons ate 37 species trees and lianas and used 5 species ofsleeping trees. Thejavan gibbons used the vegetation type which associated with Schimma wallichii andAgathislorantifolia, forest and open forest as the land cover structure. They used sub montane and montane as the vegetation ecological zone, climate type A, and various·slope classes. From tIle GIS analysis, there were 249 different land units on 5 classes suitability. The width ofeach classes are 10,088.971 ha or 54.436·% for very suitable class (81), 3,121.165 ha or 18.388 % for suitable class (82), 678.831d ha or 3.999 % for suitable enongh class (83), 2,008.837 ha or 11.835 % for not suitabl~class (N1), and 1,762.848 ha or°6.342 % for not suitable at all class (N2). The Vegetation was themain factor which influenced thejavangibbon habitat, that was·because ofthe basic characteristics ofthe gibbons as arboreal fauna.
