Judul: Studi Di Perumahan Griya Pancoran Mas Indah Rw 14, Kelurahan Rangkapanjaya Baru, Kecamatan Pancoran Mas, Kota Depok
Abstrak: The waste management in Depok is a prime problem caused by rapid inhabitant growth with its social and economic activity so that increasing the quantity of middens. In order to solve the problems, the local government launched the Household Composting Program in Griya Pancoran Mas Indah, 14th administrative unit, Rangkapanjaya Baru Sub-district, Pancoran Mas District, Depok City, held from June 2008 until now. The target of this program is 310 households in Griya Pancoran Mas Indah. The aim of this study was to evaluate the impact of this program that is behavioral change caused by household participation level on this program. The analyses used in this study are interviews and questionnaires. The amounts of 77 respondents were chosen randomly and represented each neighborhood association. The tools of analysis were used namely frequency table, cross tabulation, Spearman Correlation Test, and Chi-Square Correlation Test. The implementation of this program was to fare well because the objectives, collective action, and collective agreement are appropriate to the terms of reference, however the stakeholders was not perform their function well and the phase of program was not covering on monitoring and evaluation phase yet. The result of primary data tabulation shows that the household participation level on this program tended to high because of the influence of internal factors (age, level of education, level of revenue, duration of work and be a resident of Griya Pancoran Mas Indah) and external factors (area of yard, attendance frequency and elucidation of program). The household participation level affected behavioral change (knowledge, attitude, and action) to manage domestic waste. According to the result of this study, the composting program in Griya Pancoran Mas Indah was successfully conducted on 14th administrative unit and can be implemented in the other sub-district in order to improve any case which not appropriate to terms of reference.

Abstrak: Domestic Wasted management program is one of PT Indocement's CSR conducted in Desa Gunung Sari. This research aims on the evaluation of Wasted management program that has been running since 2009. The evaluation was conducted using CIPP concept from Stufflebeam by analyzing content, input, process, and final product as an outcome from this program. This research illustrated both the supporting and inhibiting factors from the domestic Wasted management program and also described the proceeding programs for these past 5 years. The population for this research was represented by 120 domestic house wives as corespondent, addressed in RW 04. Domestic Wasted management program in Desa Gunung Sari is running well. The supporting factors for this program are the subsidy cost from PT. Indocement CSR funds, the awareness of UPK management to be independent, creativity and the society's awareness for a cleaner environment. Meanwhile the inhibiting factors are the marketing for the final product and the lack of communications between the stakeholders.

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.
