Judul: Hubungan antara Pengetahuan dan Sikap Ibu tentang Gizi dan Posyandu dengan Status Gizi Balita di Kecamatan Pasar Rebo
Abstrak: Knowledge and mother’s attitudes about nutrition and posyandu are required to improve children feeding pattern so that adequate nutrition for the children is reached, and in this way they can grow and develop well. The purpose of this study was to analyze the correlation between knowledge and mother’s attitudes about nutrition and posyandu with nutritional status of children in subdistrict Pasar Rebo. Study design used in this study was a cross-sectional design. The sampling of this reasearch was 100 mother and their underfive children. Data processing and analysis was done using Microsoft Excel and the Statistical Package for Social Science (SPSS) version 16.0 for Windows. Based on the results of statistical test, there was a significant correlation between the level of participation of mothers with nutrition knowledge levels (p<0.05). The level of mothers nutrition knowledge had no significant correlation to level of energy and protein adequacy (p> 0.05). Mothers nutrition knowledge level had no significant correlation with nutritional status of children based index weight for age, height for age, and weight for height (p> 0.05).

Judul: Hubungan Partisipasi Ibu Balita di Posyandu dengan Pengetahuan, Sikap, dan Perilaku Gizi Ibu Balita serta Status Gizi Balita di Kecamatan Tamansari, Kabupaten Bogor
Abstrak: The objective of this research is to examine correlation between mother’s participation in posyandu with knowledge, attitude, behavior and adequacy level of children under-five nutrition in Tamansari, Bogor. This research is part of the research which its title was “a Multi-Approach Intervention to Empower Posyandu Nutrition Program to Combat Malnutrition Problem in Rural Areas” was conducted on February 2012 by using a cross sectional study design. 120 people become sample in this research were selected purposively with sample criteria are (1)have children under-five (male or female 0-60 month), (2)registered as a users of posyandu, (3)ready to be interviewed. The data which used are primary data including characteristic of family and individu sample (big of families, income of families, age, education, and job of sample, characteristic of children underfive (gender and age), mother’s participation in posyandu, knowledge, attitude, behavior of nutrition, food consumption of children under-five, and nutritional status of children under-five. Secondary data including general image of research location. The analysis was carried out with Structural Equation Modeling (SEM). Based on the analysis of SEM, mother’s participation has a significant effect on the level of nutrition knowledge (T-value =-2.59E16). Nutrition knowledge has a significant effect with nutrition attitude (T-value = -3.8323). Nutrition attitude has a significant effect with nutrition behavior (T-value = -3.8323). Nutrition knowledge has a significant effect with nutrition behavior (Tvalue = -3.8323). Nutrition attitude has a significant effect with nutritional status of children (T-value = -3.8323). Nutrition behavior has a significant effect with nutritional status of children (T-value = -5.1027)

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.
