Judul: Implementasi Medik Konservasi Pada Owa Jawa (Hylobates moloch Audebert 1798): Studi Kasus Pada Empat Lembaga Konservasi Eksitu Di Indonesia
Abstrak: The implementation of conservation medicine on 61 silvery javan gibbons (Hylobates rnolnch Audebert 1798) at The Cikananga Animal Rescue Center in Sukabumi (15 gibbons), The Surabaya Zoo (10 gibbons), The Javan Gibbon Center on Bodogol Sukabumi (6 gibbons), and The Schmutzer Primate Center on Ragunan Zoological Park Jakarta (30 gibbons), was became the objects of this cases study. The study was focused on (1) good care practices, (2) good medical practices, and (3) good breeding practices to implement good conservation medicine practices that consist of preventive, curative, rehabilitative, and promotional aspects. The main problems that faced on that practices are high number of infant mortality (62,5%), threat of zoonotics, and health problems such as gastrointestinal disorders (43,9%), musculoskeletal disorders (16,7%), respiration disorders (1 2,1%), integument disorders (1 0,6%), behaviour disorders (10,6%), and reproduction disorders (6,196). Zoonotics such as hepatitis B, TBC, and herpes was difficuit to recorded because the lack of medical check up and laboratory test. The success of breeding program was noted and seen to be depend on capability of gibbons to pairs, foods and environmental enclosure adaptation as natural condition, as well as infant care. The success of conservation medicine to solve mentioned problems are very important to maintain existence and to increase the population of silvery javan gibbons that being critically.

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: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
