Judul: Feeding Behavior of the Asian Palm Civet (Paradoxurus hermaphroditus) in MB Coffee Captive Breeding, Cianjur Regency, West Java.
Abstrak: Musang pandan (Paradoxurus hermaphroditus) merupakan satwa yang banyak dipelihara sebagai hewan peliharaan maupun untuk ditangkarkan. Penelitian ini dilakukan untuk mengetahui perilaku makan, preferensi pakan, dan membandingkan preferensi pakan pada kelas umur dan jenis kelamin berbeda. Pengamatan dilakukan pada empat ekor musang pandan jantan dan betina muda pada umur 9 bulan, dan dewasa pada umur 2 tahun di Penangkaran MB Coffee. Metode yang digunakan adalah metode continuous recording yang dilakukan pada pukul 18.00-22.00 WIB selama 22 hari. Pengumpulan data terdiri dari 6 hari pengamatan preliminary dan 16 hari pengamatan. Telah dihasilkan sebanyak 1.487 perilaku makan, terdiri dari perilaku feeding seperti mengendus, memindahkan pakan, memasukkan ke mulut, mengunyah, menelan pakan, minum, dan memotong pakan. Dapat disimpulkan bahwa dari seluruh sampel lokasi makan kesukaan adalah langsung di wadah pakan, dan pakan dengan palatabilitas tertinggi adalah buah pepaya. Berdasarkan penilaian secara skoring didapatkan hasil bahwa kelas umur dan jenis kelamin tidak mempengaruhi keseluruhan preferensi pakan Kata kunci: Musang pandan, preferensi pakan, palatabilitas, The common palm civet (Paradoxurus hermaphroditus) is an animal used in producing civet coffee which is high in taste and expensive. This study was conducted to determine feeding behavior, feed preferences, and compare feed preferences in different age and sex classes. Observations were made on four young male and female palm civets at the age of 9 months, and adults at the age of 2 years in MB Coffee Captive Breeding. The method used is the continuous recording method which is carried out at 18.00-22.00 WIB for 22 days. Data collection consisted of 6 days of preliminary observation and 16 days of observation. As many as 1,487 eating behaviors have been produced, consisting of feeding behaviors such as sniffing, moving feed, putting it into the mouth, chewing, swallowing feed, drinking, and cutting feed. It can be concluded that from all samples the preferred feeding location is directly in the feed container, and the feed with the highest palatability is papaya fruit. Based on the scoring assessment, it was found that age class and sex did not affect the overall feed preference. Keywords: common palm civet, feed preference, palatability

Judul: Studi Morfologi Usus Musang Luak (Paradoxurus hermaphroditus).
Abstrak: The study was aimed to explore the intestinal morphology of Asian palm civet. It included histochemical study on the distribution of acid and neutral carbohydrates component along the intestine of Asian palm civet. This study used three preserved intestinal organs of Asian palm civet. The sample was studied using macroscopic and microscopic approach of observations. The macroscopic observations were done by focusing on morphometric of the intestine. The microscopic observations were done by preparing histological slides and staining with hematoxylin eosin (HE), alcian blue (AB) pH 2.5, and periodic acid Schiff (PAS). The results showed that Asian palm civet’s caecum was curved like a comma and the colon was short without segment. The average length of the intestine were 140.06±13.09 centimeters. The lenght ratio of intestine to body were 1:3 that was noted as in between insectivores and carnivores. Asian palm civet intestinal’s wall was composed of inner mucosa, submucosa, tunica muscularis, and outer serosa with varying in thickness. There were submucosal lymphatic tissue in ileum that formed Peyer’s patches and solitary lymphatic nodules in caecum. The distribution of acid and neutral carbohydrates were found in the intestinal mucosal in goblet cells and glandular epithelial of crypt Lieberkuhn. The Brunner’s glands only were gave positive reaction to PAS staining. The morphology of the intestine of the Asian palm civet more closely to those on carnivores than those which found in omnivores.

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.
