Judul: Analisis kepuasan konsumen terhadap produk dan pelayanan rumah makan Pecel Lele Lela Bogor
Abstrak: Restaurant is a general term to refer to the gastronomic venture that serves the community and provides a place to enjoy the dish and set specific rates for food and service. In this case one of the restaurant which is a franchise business or franchise that serves catfish is Pecel Lela Restaurant located in the office Jl. Jend. Sudirman, Bogor. During provide culinary services restaurant fluctuated number of visitors who often makes its own concerns for managers both in extending its franchise license or in other decisions. Responding to the manager really needs to consider anticipatory measures by way of diagnosing directly through customer satisfaction surveys that need to be made to the minimum community begins with a study of consumers who came to then take a decision at a later stage. Based on the analysis conducted on 60 respondents (consumers) are Pecel Lela Restaurant serving food should speed up the time ordered by the consumer, serves favored or preferred by consumers so they can refer to friends or family, and the promotion of Restaurant Pecel Lele Lela itself.

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.
