Abstrak: Young female sheep require adequate energy to improve their performance and reproduction. However, in reality most farmers are not aware of the condition. This experiment was aimed at investigating the effect of different energy levels on the performance of young female sheep. Twelve post-weaning female sheep with average body weight of 9.67 ± 1.72 kg were used in this experiment and fed three rations with different energy levels for 89 days. The rations as treatments consisted of P1= ration with 65% TDN; P2= ration with 70% TDN; and P3= ration with 75% TDN. The experiment used completely randomized design, and data analysis were done with analysis of variance. Further analysis was conducted using orthogonal contrast. Results of the experiment show that different energy levels did not significantly affect consumption of TDN, crude protein, body weight gain, and feed efficiency, but it significantly (P < 0.05) influenced the Ca consumption. It is concluded that ration with 65% TDN is sufficient to support the performances of young female sheep.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied.

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.
