Judul: Kasus Peternak Domba di Kelurahan Cimahpar, Kecamatan Bogor Utara, Kota Bogor, Jawa Barat
Abstrak: Cimahpar’s Village represent one of a village in Bogor City which some of its society are sheep farmers. Motivation of sheep farmers is important aspect in livestock development. The research aims are needed the sheep farmer characteristics, motivational level of sheep farmers, and influencing of motivation level factors of sheep farmers in Cimahpar’s Village, Subdistrict of North Bogor, Bogor City, West Java. The research conducted on June-July 2005 at Cimahpar’s Village, Subdistrict of North Bogor, Bogor City, West Java. The total of sheep farmers as population are 390 farmers. Sample take by simple random sampling, totaly 63 farmers. The results indicated that the motivation of sheep farmers in Cimahpar’s Village categorized medium. It’s mean that sheep farmers in Cimahpar’s Village have motivation to manage sheep livestock, including to increase sheep productivity. Those motivation influencing by age, number of family members, education and knowledge of market information. This research recommended as follow. Sheep farmer need facilitate to build group farmer sheep that orientate to increase sheep farmer economic condition. The institute expected able to assist the sheep farmer in marketing and on farm aspect, including livestock produce accomplishment. All the activity will be more succeed if followed with the activity of empowerment of sheep farmer.

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.
