Introduction
Javan gibbon (Hylobates moloch) is a kind of primate Hylobatidae tribal members. With the remaining population between 1000-2000 tail only, gibbon apes are the most endangered species in the world. Javan gibbon is endemic fauna of the island of Java, in English known as the Javan Silvery Gibbon, Javan Gibbon, Moloch Gibbon, and the Silvery Gibbon. While in Latin (scientific) members of the Order Primates (Primates) is referred to as Hylobates moloch (Audebert, 1798) is synonymous with Hylobates cinera Cuvier (1798) Hylobates javanicus (Matchie, 1893) Hylobates leucisca (Schreber, 1799) and Hylobates pongoalsoni (Sody, 1949). Javan gibbon limited spread (endemic) in western Java. Javan gibbons do not have tails, and relatively long arms compared to her size. This long hands needed to swing and move between branches and twigs high in the forest canopy, where everyday activities. Her grayish color, with darker side top of the head and face black.

These apes live in small groups, a kind of nuclear family, consisting of a pair of male and female animals, with one or two children who are still minors. Javan gibbon is a faithful partner, monogamous. The average female gibbon give birth once every three years, with the period contains over 7 months. Her children are breastfed until the age of 18 months, and continues with his family until adulthood, which he reached the age of about 8 years. Young gibbon then will separate themselves and find their own spouses. Javan gibbons are diurnal and arboreal animals, fully lived above the canopy of trees. Mainly feed on fruits, leaves and flowers, a small group of Javan gibbon explore the forest canopy by climbing and swinging from one tree to another tree to rely on agility and strength of his arm. The average body weight of up to 8 kg. This group will try to defend their territory, usually the extent of up to 17 hectares, of the presence of other groups. Early in the morning, and also at certain times in the afternoon and evening, a female gibbon will make itself heard to announce the family's territory. Of voice blared between groups, and heard up to this distance, the researchers can estimate the number of existing gibbon groups, and further to quantitate individual. This species is only found in the western part of Java Island, namely in the forests of lowland and lower montane forests. Easternmost deployment is in the region of Mount Slamet as well as in the ranks of the Dieng Mountains west in the region of Pekalongan.

There are two subspecies of Javan gibbon, namely:
• Owa western Java, Hylobates moloch moloch and
• Owa Central Java, Hylobates moloch pongoalsoni
Efforts
Because the population is declining, IUCN Redlist enlisted the Javan gibbon conservation status of "Endangered" (EN Endangered). In addition, CITES also incorporate these rare primates on the list of Appendix I, which means it should not be traded. The main cause of the increasing scarcity of Owa Jawa is habitat loss due to forest destruction (deforestation) and the conversion of agricultural land. Whereas Owa Jawa including wildlife is very 'love' territory in which despite its territory (territorial) began to run out of this endangered primates remain unmoved and did not want to move. This potentially makes Owa Jawa starve to death. In addition to the loss of forests, as the Javan gibbon habitat, poaching also memjadi cause of the increasing scarcity of Owa Jawa. Often hunting is done by shooting dead Javan gibbon mother to take her child. One of the conservation measures to prevent the extinction of the Javan gibbon is the formation of Rehabilitation and Rescue Centre Owa Jawa Bodogol in the National Park of Mount Gede Pangrango. The rehabilitation center is maintained a number of Owa Jawa then do the matchmaking efforts between Owa Jawa before being released in the wild.

This is done with consideration other than monogamous animals, Owa Jawa will not be able to survive if released in the forest without the pair as they relate to the process of marriage and protection of the area. Conservation measures undertaken by the Centre for Rehabilitation and Rescue Owa Jawa Bodogol is good news for the Javan gibbon and we all. But this measure is certainly not sufficient means to avoid Si Genit Owa Jawa of extinction without strict law enforcement, including synergy government policies that are in line with the central government. The latter of course, concerns the whole society not to capture and maintain Genit Si Javan gibbon is endangered.
