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: Manajemen Penangkaran dan Aktivitas Harian Musang Luwak (Paradoxurus hermaphroditus, Pallas 1977) di Penangkaran CV Kopi Luwak Indonesia Pangalengan, Bandung
Abstrak: Common palm civet (Paradoxurus hermaphroditus) is a species that potential to produce tasteful and expensive luwak coffee. This potential cause the hunting of common palm civet by coffee farmers where if there is no effort on its cultivation it will lead to the decrease of population for this species. Common palm civet conservation efforts can be done through the ex-situ conservation by captivity. This research was conducted to study the captive management practices and daily activity in CV Kopi Luwak Indonesia so that it can be used as a reference in the easy management captivity of common palm civet The research was held in CV Kopi Luwak Indonesia captivity Pangalengan, Bandung in May, June and October 2012. The data and information collected covers (1) the technical aspects of captivity, including seed, cage, feed, reproduction, health were obtained by field observations, measurement and interviews; (2) consumption and palatability arabica coffee was obtained by field observation and measurement; (3) the daily activities was obtained by focal animal sampling method; and (4) utilization of captive breedings obtained by field observations and interviews. CV Kopi Luwak Indonesia captivity managed with the intensive system and developed with the core and plasma system. Technical captivity of common palm civet in CV Kopi Luwak Indonesia covering (a) seed; seeds from capture in nature with the age of two years (b) cage; there are two kinds of cage which are main and quarantine cage (c) feed; kinds of feed which was given to common palm civet are banana, chicken, arabica coffee, a mixture of carrots, papaya, eel, catfish, and goldfish; (d) reproduction; the captivity have not successful in breeding; (e) health; types of disease/disorder suffered were wormy and stress. Health management was done by cage cleansing, health checking, vaccine, vitamins and medicine giving. The average amount of consumption of arabica coffee is 306 grams/individuals/day. Common palm civet prefer large and maroon arabica coffee small and red ones with the palatability values 30%. Most activities of both individual common palm civet male or female were feeding activities. Total production of luwak coffee in green bean form from CV Kopi Luwak Indonesia Captivity is 60 kg/month. The profits earned from the production of luwak coffee is Rp 40.709.500/month.

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.
