Judul: Performa Dan Morfometrik Domba Ekor Gemuk Dengan Pemberian Pakan Konsentrat Dan Limbah Tauge Pada Taraf Pemberian Yang Berbeda
Abstrak: Performance and morphometric are a description of conditions which reflect the growth and development of livestock. Generaly, these are influenced by genetic and environmental factors. Genetically, fat tailed sheep is one of a local sheep, which is fast in growth and can adapt in the tropical climate. Feed is one of the environmental factor, which can influence the growth. This research was conducted to determine the performance and morphology of fat tail sheep male (under one year old) that fed by concentrate and sprouts waste at different levels, they were P1 = 100% concentrate + 0% sprouts wastes, P2 = 75% concentrate + 25% sprouts wastes, P3 = 50% concentrate + 50% sprouts wastes and P4 = 25% concentrate + 75% sprouts wastes. The sheep were classified into two groups are small and large body weight. The Data were analyzed using randomized block design with four treatments and two blocks. The results of this research show that the treatments had significantly (P<0.05) influenced the sheep performance but they do not have significant result on the sheep morphometric.

Abstrak: Sheep farming has been increasing to meet demand of animal protein for human needs. In the livestock business, feed cost is the largest cost. In this study, bean sprouts waste which have no economic value was used as a sheep feed to increase sheep productivity. Productivity of sheep was affected by internal factors and external factors. The external factors are physiological responses and the internal factors are nutrient contents of feed. Bean sprout waste contains 13,63% of crude protein and 49,44% of crude fiber which are useful for sheep feed. The treatment level were P1 (100% concentrate), P2 (75% concentrate + 25% bean sprout waste), P3 (50% concentrate + 50% bean sprout waste), and P4 (25% concentrate + 75% bean sprout waste). The result showed that physiological response and palatability were increased along with the increasing of bean sprouts waste in the feed content. In this research, there were no significant relationship between palatability and physiological response.

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.
