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.

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: Bifurkasi Hopf pada Model Siklus Bisnis Kaldor Kalecki tanpa dan dengan Waktu Tunda
Abstrak: Business cycle model is one of dynamical system models in economic. One of the business cycles model is Kaldor-Kalecki model. Kaldor-Kalecki business cycle model that is written in delayed defferential equations, is a business cycle model that involves gross product and capital stock of a company. In this paper Kaldor-Kalecki business cycle model is analyzed using both nondelay and delay in time of capital stock. By Taylor expansion for the time delayed model, an analysis of stability around the fixed points has been done. Furthermore, by using Hopf bifurcation theorem, it can be shown that there exists periodic orbits and limit cycle. In the nondelayed model, changing the parameter of goods market could lead to the occurrence of Hopf bifurcation and the existence of limit cycle. Similarly, for the delayed model, it has been shown that changing the time delay parameter may result in the occurrence of Hopf bifurcation and limit cycle.
