Judul: Motivasi dan Perilaku Menonton Program Acara Merajut Asa Trans7 pada Petani Desa Citapen, Kabupaten Bogor
Abstrak: This study aimed to asses the correlation between demographic characteristics with viewing motivation, the correlation between social groups affiliation with viewing motivation, the correlation between personality type with viewing motivation, and the correlation between viewing motivation with viewing behavior of watching Merajut Asa Trans7 program. The research sample was farm worker in RW 05 Citapen Village who had seen the program. The results of the study explain that gender associated with integration and social interaction motivation and additional work associated with personal identity motivation. Age, level of education, income levels, family’s size, and the type of personality was not associated with viewing motivation. The level of social group affiliation associated only with information motivation and personal identity motivation, while viewing motivation was not related with viewing behavior of Merajut Asa Trans7 program.

Judul: Perilaku Menonton dan Kepuasan Petani terhadap Program Merajut Asa Trans7 di RW 05 Desa Citapen
Abstrak: This study aims to identify the behavior of the audience watching television, as well as analyzed the relationship between viewing behavior with the level of audiences satisfaction the programs Merajut Asa Trans7. The method was used in this study is a survey method with the quantitative approaches supported by qualitative data. The results of this study explain the choice of the most popular by farmers is the program information and entertainment. Farmers have a low duration of watching television, i.e. during 7.50-45.75 minutes/day, as well as the duration of watching programs Merajut Asa Trans7 also low, i.e. during 1-15 minutes. Farmers have a low frequency of watching television, the only watch 1-4 times a week. Frequency of watching programs Merajut Asa Trans7 also low, i.e. 1-2 times a month. Duration of watching is not associated with the level of audiences satisfaction. Frequency of watching associated with the level of audiences satisfaction, i.e. satisfaction information.

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.
