Judul: Knowledge base development system of cultivation broiler closed house
Abstrak: Protein requirement of Indonesian people is increasing due to the increase of population. Broiler is popular meat, cheap, and easy to obtain. However, broiler production still does not to fulfill the needs of the people of Indonesia flesh. The main cause of inadequate broiler production is still conventional farming systems. This research aims to design and build a knowledge base broiler farming management using a variety of computer-based application system that provides knowledge in the form of stages - stages of cultivation which include DOC management, the management of food and drink, environmental management, and agriculture-based disease management precision and stored in the system database. DBMS closed cultivation broiler house to be built will be concentrated on the four points which include DOC (Day Old Chick), food, environment, and disease. DOC will be informed at the point related guidance in the selection and management of initial DOC. In the feed point will be informed about the density of the cage, feed system and drinking system. Point environment will provide information related to litter, temperature, ventilation, and lighting. Point of disease is the last point to be discussed, the point will be informed of the name of a possible disease suffered by broiler chickens, the cause of the disease, prevention and treatment.

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.
