Judul: Persepsi dan minat pemuda terhadap usaha peternakan domba (kasus pemuda desa Neglasari kecamatan Dramaga kabupaten Bogor)
Abstrak: Livestock sector is important especially when Indonesian nation face various crisis of endless economics because it helps to overcome this problem. Livestock sector is not only without problem, a lot of matter influence this sector to be an important sector in development. One of them is shifting job opportunity work in livestock sector. Friction of opportunity work in livestock sector at least influences perception and young men interest, one of them is effort sheep ranch. This research was done in village of Neglasari sub district od Dramaga at April 7th May 7th 2007. Design of this research is Descriptive of Correlation by 50 sponders taken in the Census.

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.
