Abstrak: The objectives of this study were to determine the Food acceptance, nutritional adequacy level and and nutritional status of drug addicts at Rumah Singgah PEKA and YAKITA Bogor. This study used cross sectional design. Subjects of this study was resident at Rumah Singgah PEKA and YAKITA Bogor. Sampling method used was purposive sampling and the number of subjects was 30 people. Descriptive analysis nutritional adequacy level showed energy and protein, most of the resident in YAKITA was on normal category (69.2%). Nutritional adequacy level energy (29.3%) and protein (64.7%), are resident in Rumah Singgah PEKA categorized as severe deficit. Food acceptance includes of color, aroma, texture, shape and taste of food at Rumah Singgah PEKA and YAKITA Bogor, most of the resident was on category of like. Nutrition status of resident at Rumah Singgah PEKA and YAKITA, most of the resident was on normal category.

Abstrak: The objectives of this study were to determine the nutritional status, health status, consumption pattern and food acceptance of the elderly at Rumah Perlindungan Sosial Tresna Werdha Bogor. This study used cross sectional design. Research was done in October 2013. The subjects of this study were 34 elderly people with age over 60 years. Results showed that the average energy and protein consumption in elderly were 1454 kkal and 41.7 g. Food acceptance of elderly were adequate for taste of food (52.9%) as well as the portion of food (61.8%). The adequacy level of energy and protein mostly were deficit. Most of the elderly (41.2%) had normal nutritional status. The majority of the elderly (67.6%) were suffering from hypertension with mild hypertension. Correlation test results showed no significant relationship (p>0.05) between the adequacy level of energy and nutrient with nutritional status. Pearson correlation test results showed no significant relationship between blood preasure (p>0.05) and nutritional status.

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.
