Judul: Medis konservasi berbasis kesejahteraan hewan : studi kasus pada orangutan di Taman Margasatwa Ragunan
Abstrak: Studi kasus ini bertujuan untuk mempelajari implementasi medik konservasi berbasis kesejahteraan hewan pada orangutan di Taman Margasatwa Ragunan (TMR). Metode penilaian dilakukan berdasarkan indikator kesejahteraan hewan menurut standar South East Asian Zoos Association (SEAZA, 1998) dan World Association of Zoos and Aquaria (WAZA, 2003) yang diadaptasi oleh Perhimpunan Kebun Binatang Seluruh Indonesia (PKBSI, 2004). Studi kasus dilakukan di Taman Margasatwa Ragunan. Pendekatan penilaian animal welfare dilakukan berdasarkan ketersediaan fasilitas dan sistem manajemen pengelolaan orangutan. Hasil penilaian implementasi lima freedom kesejahteraan hewan pada orangutan dengan nilai antara 1-5 diperoleh nilai sebagai berikut: di K.Made (4 ekor) 3.5; K.Mengden (22 ekor) = 3.1; K.Sumatera (1 ekor) = 3.5; K.PPS Luar (3 ekor) = 3.7; dan K.PPS Dalam (13 ekor) = 3.9 dan rata-rata untuk Taman Margasatwa Ragunan adalah 3.5. Dari kajian ini disimpulkan bahwa implementasi prinsip 5 freedom animal welfare di Taman Margasatwa Ragunan masuk ke kategori cukup dan jumlah orangutan tidak berpengaruh terhadap tinggi-rendahnya nilai kesejahteraan hewan. Untuk meningkatkan status kesejahteraan orangutan, disarankan perlunya perbaikan sarana dan prasarana maupun peningkatan mutu manajemen dan petugas. Studi kasus ini memberikan gambaran bahwa tugas dokter hewan dalam medik konservasi, diantaranya adalah melakukan kontrol fisiologi, kontrol adaptasi, kontrol mikrobiologi, kontrol kualitas, kontrol reproduksi, kontrol genetik, dan kontrol behavior.

Judul: Pengelolaan Kesejahteraan Musang Luwak dan Pemanfaatannya sebagai Satwa Peraga di Taman Margasatwa Ragunan
Abstrak: Ragunan Zoo is one of the conservation organizations that carried animals management based on the principles of ethics and animal welfare. Beside that, it also has a function as recreation place.The purpose of this research is to identify and analyze management of common palm civet welfare and its of prosperity level in Ragunan Zoo, measuring interests of the visitors Zoo about the common palm civet, and also make recommendations for better management in common palm civet welfare.The results showed that management of common palm civet in Ragunan Zoo consists of three main activities, which are housing, feeding, and health. The welfare of common palm civet in Ragunan Zoo also classified as good. This animal is one of the favorite animals viewed by visitors. The recommendation that Ragunan’s management to put a lot of their attention in cages of common palm civet, because many of the cages are need to be repaired

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
