Judul: Study on productivity and product of greater mouse deer (Dagarlus napu) in Jambi Province
Abstrak: Thirty-seven wild greater mouse deer (T. napu) were used to study productivity and pducts. The research were: 1) survey; 2) a preference test an feed, and 3) Product The feed offered were kangkong (Ipmoea aquatia), cabbage (Brmsica olmucea& aafirata), cassava leaves, cassava skin and cassava m i h o t esculenta mauz), banana kepok skin FWbanIa na di skin (Miisa pradiss~am)a nd sweet potato ( I p m t a batatus). Five young adult animals (greater mouse deer, one f d e and four males) weighlng 3017 i 707 g, they were kiHed by exasunguination The greater mouse deer body very spesific, the color are orangey-brown and ashes-white, nocturnal animal and solitary nature, matting occurs throughout the year, were observed comurned higher mount of h i t s than vegetable. A preference test on feed, when fresh weight of the feed was considered, the male and female greater mouse deer consumed cassava the most (93.40 f 2 1.91 gld and 103.67 f 23.98 g/d for female snd female, respectively), followed by banana uli skin In the term of dry matter intake (DMI) of the feeds, the amount of cassava consumed was the highest for both male and female greater mouse deer, followed by sweet potato. The total DM1 was 108.96 f 18.42 dd, average daily gain did not differ between sex The male mouse deer gained 4.62 + 1.% gld while the female gained 5.34 f 2.67 gld. Dressing percentage was 59.3 1% and proportion of carcass meat reached 73.46 %. The fat percentage and cholesterol concentrations of longissirnus dorsi muscle very low (1.43% d 13.17 mg1100g respectlvdy), while the lipid fractions showed that the total lipid were composed high levels of polyunsaturated fatty acids (PUFA). The lipid composition of greater mouse deer tissue may serve as a model for dietary lipid recommendations in trdng and preventing chronic desease.

Judul: Perilaku dan Aspek Pakan Rusa Timor (Rusa timorensis Blainville 1822) Remaja Pada Kandang dan Jenis Pakan yang Berbeda
Abstrak: Efforts to improve the productivity of java deer (Rusa timorensis) can be done through improvements in the feed management and maintenance customized with deer behavior. This research aims to study the aspects of feed and daily behavior of java deer in adolescent age group (12-24 months) in captive breeding of Hutan Penelitian Dramaga, Bogor. In this study, deer were fed selective forage (Coix lacryma-jobi Lour, Pennisetum purpureum Schum, Hierochloe horsfieldii Maxim, and Commelina benghalensis L) and field grass. Result show on individual cages, the highest feed preference value was Pennisetum purpureum Schum and the highest feed palatability value was Hierochloe horsfieldii Maxim. The opposite result occured in the collective cage. On feeding selective forage, the average daily consumption of fresh and dry matter of feed, daily gain and feed efficiency deer were 4.87± 0.51 kg/head/day, 0.73±0.07 kg/head/day, 0.15±0.05 kg/head/day and 22.59%. Averaged digestibility coefficients of feed of java deer was 52.95±6.90% of dry matter, 30.87±26.00% of crude fat, 49.68±2.76%of crude protein, 56.49±6.48% of crude fiber, and 59.21±8.40% of N-free extractive. Daily behavior of java deer in individual cages were dominated by eating, rumination, movement and resting. In conclusion, to increase production that deers is better to be raised on individual cages.

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.
