Judul: Evaluasi Program Pos Pemberdayaan Keluarga (Posdaya) : Studi Kasus Posdaya Bina Sejahtera di Kelurahan Pasir Mulya, Kecamatan Bogor Barat, Kota Bogor, Jawa Barat
Abstrak: In respond to the government programs to alleviate the poverty and to improve the quality of the human resources of the remote communities, the family empowerment program was established. The establishment of such community development program is attempted to reach the target of the millenium development goals (MDGs), in its special interest for remote community development. The objectives of the study are: 1) to evaluate the progress of the Sejahtera Family Empowerment Program; 2) to investigate contraints and factors that support the development of the Empowerment Program; and 3) to analyse input, output, process and effects of the Posdaya Bina Sejahtera Program, on the community of Pasirmulya, Western Bogor District, West Java. Qualitative as well as the quantitative approach were utilized, in this study. Qualitative approach was used to get the deep understanding of the implementation of Family Empowerment Program, whereas the quantitative approach was used for the case study. Both the qualitative and quantitative approaches were sinergically utilized for more comprehensive result. For data collection, 50 questionaires were administered for community leaders, Bina Sejahtera officials, and community members purposively. This study brings together the current state of knowledge of how Posdaya has changed the quality of life of the community. From this study, it is suggested that Center for Human Resource Development (P2SDM) IPB, Yayasan Damandiri, as well as the Government should hands in hands to continue supporting the empowerment program.

Judul: Tingkat Partisipasi dan Kemandirian Masyarakat dalam Bidang Ekonomi Program Posdaya (Kasus Posdaya Bina Sejahtera Kelurahan Pasir Mulya Kota Bogor)
Abstrak: Posdaya program is a service institution on family empowerment provided for community to reach welfare through integrated eight family functions. This study aims to analyze both internal and external factors dealing with participation and independence and the relation between community’s participation and independence in the economic view upon “posdaya” program of Bina Sejahtera Posdaya. The study used explanatory research designs involving 87 respondents; namely, the community becoming the members and participants of posdaya. The technique used to determine the samples was simple random sampling, while the method to gather data was by survey. Data were then analyzed by applying descriptive statistics including frequency, percentile, score mean, score total, and cross tabulation. Meanwhile, to test the correlation, Tau B- Kendall with the help of SPSS version 17 was used. It was found that community’s participation in economic view was significantly low in the aspects of planning, implementing, and evaluating the results, whereas the aspect of enjoying the result fell into the low level. Conversely, the independency on mental attitude belonged to the high level. Furthermore, the internal factors that showed an obviously positive correlation with participation were formal education, family income, and cosmopolitans, whereas the external factors comprised the support for family, the roles of both key persons and assistance. Moreover, the external factors which were positively correlated with independence were family support and the roles of the key persons and assistance. Likewise, the significantly positive correlation was found in the level of participation and independence of the community in the economic view of posdaya program.

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.
