| dc.description.abstract | Area Gunung Halimun – Salak National Park is the habitat of endemic primate of Java, Javan Gibbon (Hylobate moloch Audebert, 1798). This species life is dependent on existence of big trees, because Javan Gibbon is arboreal species which travelled and fed from one branch to another. Javan Gibbon is one of nine primate species in the world that only spread in Asia. By knowing space application pattern of Javan Gibbon based on calling behaviour, hopefully the zone maintaining action is basicly done based on habitat and ecosystem important species. The aims of the research are to knowing the space application pattern of Javan Gibbon based on calling behavior each group structure. The research can be considered information for habitat management of Javan Gibbon. The research was conducted for two month from HM 6 – HM 33 and the area arrounds it. The equipments were used are work map, camera, binocular, stopwatch, compass, tallysheet, range finder, rope and stationery. The objects are two groups of Javan Gibbon (Hylobates moloch Audebert, 1798). Monitoring was done with scan sampling method. The method to collecting data is using continous recording method. Data from the research were analyse by graphic and descriptive illustration technique. Calling behaviour which have been done by group A during the research was counted 29 calls that consist of 26 calls by directly observed and three calls by indirect observed. Group B was counted 16 calls that consist of 14 calls by directly observed and two calls by indirect observed. Based from the observation, calling behaviour mostly happened at 10:00 – 11:00 AM. H. moloch calling behaviour is 69% using canopy B, 26% using canopy A and 5% using canopy C. Adult female song bouts observed at 16 different trees for 4785 second. Adult male song bouts observed at eight different trees for 1547 second and sub-adult female song bouts observed at six different trees for 262 second. All of the group structure used Rauh, Scarrone, Attims and Massart model architechture tree. The conclusions from this research are the adult female used 15 Rasamala (Altingia excelsa) as calling tree and used 17 Scarrone model architecthure tree for calling. Position AI and AII were used for female song bout (FSB); AI, BI, ang BII were used for border conflict call bout (BCCB); AIII, BIII and CIII were used for harassing call bout (HCB). Adult male used three Ki haji (Dysoxylum alliaceum) and five Rauh model architechture tree as calling tree. Position AII were used for border conflict call bout; CIII were used for harassing call bout; BI, BII and CII were used for male song bout. Sub-adult female used five Kimokla (Knema cinerea (Poir.) Warb.) which have model architecthure tree, Massart as calling tree. Position AII ang AIII were used for female song bout and harassing call bout; BI, BII ang BIII were used for harassing call bout.
