Judul: Keragaman Konsumsi Pangan dan Hubungannya dengan Status Gizi pada Orang Dewasa di Perkotaan
Abstrak: This study aimed to analyze the diversity of food consumption and the association with nutritional status among adults in urban area especially in DKI Jakarta. This study using a cross sectional design and secondary data. Subject were 102 adults. The data collected were socio economic characteristic (age, education, family size, nutritional status (BMI and waist hip ratio), food consumption (nutrition intake and dietary diversity score) and healthy status. Diversity of food consumption can measured by Dietary Diversity Score methods and the results showed that most of subject has a good food diversity. Spearman correlation test showed that there was a positive relationship (p<0.05) between BMI with healthy status and education with iron consumption. Other variables observed were not significantly related (p>0.05).

Abstrak: This study was aimed to assess food consumption of people in DKI Jakarta. The design of this study was cross sectional study. The study which is conduted from analyzing food consumption data of Basic Health Research 2010 collected by a 24-hour recall method. Subject obtained from1626 households with 4964 household members.The result showed that energy consumption average of households stood at 1500 ± 711.48 kkal/cap/day and protein consumption average of households stoodat 50.82 ± 27.1 g/cap/day.Almost all (53.1%) energyadequacy level (TKE) households stood atextreemly leveldeficit category,proteinadequacylevel (TKP) households stood at normal category (47.2%) and desirable dietary pattern (PPH) stood at76.6. Spearman test resultshowed there wasno significant correlation(P>0.05) between maternal education level, number of household memberand food expenditure to householdsTKE and TKP.

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.
