Judul: Profil Hematologi dan Performa Ambing Kambing Peranakan Etawah (PE) Dara yang Diberi Bawang Putih (Allium sativum)
Abstrak: The aim of this research was to evaluate the effect of garlic in etawah crossbred goat ration on hematology profile and udder performance. This research used 10 etawah crossbred goats devided into 2 treatment groups. First group was given control feed (R0) without garlic, and second group was given control feed plus 0.15% garlic (R1). The ratio of forage to concentrate in dry matter base was 16:84. Parameter measured were dry matter consumption, nutrient intake, body weight gain, hematology profile, and udder performance. The data was compared with T-test analysis. The results showed that 0.15% garlic at ration had not affected to nutrient consumption, hematology profile and udder performance

Judul: Profil Darah Kambing Peranakan Etawah Laktasi yang Mendapat Ransum dengan Berbagai Level Indigofera sp. Berbentuk Pellet
Abstrak: This research was conducted to evaluate the effect of level Indigofera sp. in the pellet ration on blood profile and physiological status of lactating etawa crossbred goat. Nine lactating goats with average body weight of 32.4 kg, were randomly divided into 3 treatments. The Rl contained pellet ration without Indigofera sp., R2 was pellet contained 20% Indigofera sp. and R3 was pellet contained 40% Indigofera sp. Each group consisted of 3 lactating goats. Drinking water provided ad libitum, while forage was given in the morning and afternoon. Variables measured were feed intake, physiological status and blood profile. This research was designed as block randomized design and data was analysis using ANOVA. The result showed that there were no significant effect of 40% Indigofera in the ration to blood profile, physiological status and feed consumption. The highest blood glucose concentration was in goat received pellet containing 20% Indigofera sp. in the ration and the highest blood urea concentration was in goat received containing 40% Indigofera sp. in the ration.

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.
