Penilaian Kesiapan Pelepasliaran Owa Jawa (Hylobates moloch) di Javan Gibbon Center, Taman Nasional Gunung Gede Pangrango

Abstract

Owa jawa merupakan primata dilindungi yang masih diperdagangkan. Salah satu upaya konservasi owa jawa yaitu rehabilitasi sebelum dikembalikan ke alam liar. Penilaian kesiapan pelepasliaran merupakan salah satu cara untuk memastikan bahwa owa jawa dapat bertahan hidup setelah dilepasliarkan. Penelitian dilaksanakan di Javan Gibbon Center untuk menduga alokasi waktu aktivitas harian owa jawa pada masa rehabilitasi; dan membandingkan pola perilaku dan alokasi waktu aktivitas harian antara owa jawa masa rehabilitasi dengan owa jawa liar. Penelitian dilakukan pada bulan April selama 11 hari dengan mengamati aktivitas dua pasang owa jawa di kandang. Data tersebut kemudian dibandingkan dengan aktivitas owa jawa liar dan dimasukkan ke dalam tabel penilaian kesiapan pelepasliaran individu owa jawa. Tingkat kesamaan aktivitas harian owa jawa rehabilitan dengan owa jawa liar bervariasi, mulai dari 34,16-90,96% dengan tingkat kesamaan tertinggi pada aktivitas bergerak dan terendah pada aktivitas seksual. Pola perilaku bimodal tidak berlaku pada owa jawa di kandang rehabilitasi. Objek penelitian yang diamati masuk ke dalam kategori siap untuk dilepasliarkan.

Javan gibbons (Hylobates moloch) are protected primates that are still being traded. One of the conservation efforts of the javan gibbon is rehabilitation before being returned to the wild. Assessment of release readiness is one way to ensure that the javan gibbon can survive after being released into the wild. The study was conducted at the Javan Gibbon Center to estimate the time allocation for the daily activities of the javan gibbons during the rehabilitation period; and comparing behavior patterns and time allocation of daily activities between Javan gibbons during rehabilitation and wild javan gibbons. The study was conducted in April for 11 days by observing the activity of two pairs of javan gibbons in a cage. These data were then compared with the activity of wild javan gibbons and entered into a table for assessing individual release readiness of javan gibbons. The level of similarity in the daily activities of the rehabilitated Javanese gibbon with the liar Javan gibbon varied, ranging from 34.16-90.96% with the highest level of similarity in moving activities and the lowest in sexual activity. Bimodal behavior patterns did not apply to Javan gibbons in rehabilitation cages. The observed object of research is categorized as ready to be released into the wild.
