Judul: Animal Welfare Level and Readiness Status of Javan Gibbon in Rescue and Rehabilitation Center for Released
Abstrak: Owa jawa (Hylobates moloch Audebert 1798) merupakan satwa primata endemik Pulau Jawa. Permasalahan yang dihadapi oleh primata ini adalah penurunan populasi yang disebabkan oleh kerusakan habiat, perburuan liar, dan perdagangan liar. Pendirian Lembaga Konservasi dijadikan sebagai upaya pemulihan populasi owa jawa secara eks-situ. Salah satu Lembaga Konservasi yang bergerak di bidang pelestarian owa jawa adalah Javan Gibbon Center (JGC). Menurut Peraturan Menteri Kehutanan nomor 31 tahun 2012, pengelolaan Lembaga Konservasi dilakukan berdasarkan prinsip etika dan kesejahteraan satwa. Sebagai Pusat Rehabilitasi Satwa, JGC memiliki kewajiban untuk melakukan pelepasliaran sehingga perlu dilakukan penilaian terhadap kesiapan pelepasliaran owa jawa., Javan Gibbon (Hylobates moloch Audebert 1798) is endemic primate from Java Island. The problem faced by this primate is population decline caused by habitat destruction, illegal hunting and illegal trade. Establishment of Conservation Institution serve as javan gibbon population recovery effort in exsitu. One of the Conservation Institution which concern in javan gibbon conservation is Javan Gibbon Center (JGC). According to the Forestry Ministry Regulation number 31 2012, management of Conservation Institution based on principal of ethics and animal welfare. As Animal Rehabilitation Center, JGC has obligation for release therefore, it is necessary to do assessment to readiness of javan gibbon release.

Judul: Studi Pakan Owa jawa (Hylobates moloch Audebert 1798) di Pusat Penyelamatan dan Rehabilitasi Satwa Javan Gibbon Center (JGC)
Abstrak: Javan Gibbon is a protected animal based on PP RI no. 7 1999. The problems in nature habitat are fragmentation, illegal logging, illegal hunting and illegal trade. One of the ex-situ conservation effort is by building Javan Gibbon Rescue and Rehabilitation Center. Feed management in conservation institution is needed in order to choose feed priority by seeing the palatability and nutrition intake. The purpose of this research are to identify the palatability, nutrient intake and the relation beetween diet menu with the amount of feed election, feed consumption, and energy intake. Focal animal sampling and restricted feeding are used by giving two different diet menu. The first rank of palatability is banana for the first menu and the second menu. The amount of the energy intake from the first menu is 327.47 kcal and from the second menu is 351.27 kcal. There is no significant deferences between diet menu with the mount of feed selection, feed consumption and energy intake.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
