Judul: Hubungan Perilaku Gizi Ibu dengan Kecukupan Energi, Protein dan Zat Gizi Mikro Keluarga pada Pemukiman Kumuh Di Jakarta Selatan
Abstrak: Determinant and regulator of family eating habit is a mother. Therefore, knowledge, attitudes, and practices of maternal nutrition essentially to be considered and improved. The purpose of this study was to determine the relationship between maternal nutritional behaviour with famili’s nutrient adequacy in slums at South Jakarta. The samples in this study were family and mother as the unit of analysis. The research was conducted by interviewing the unit of analysis. Mothers in this study has good knowledge and attitudes of nutrition, but their practises of nutrition was moderate. Over all, energy adequacy of family was still deficit, but protein adequacy was enough. Adequacy of vitamin A, vitamin B, and phospor were adequate, but calcium, iron, and vitamin C were deficit. Stepwise regression results indicate that maternal nutrition knowledge, attitude, and practice does not affect the nutritional adequacy of family who lived in slum at South Jakarta.

Judul: Positive Deviance Status Gizi dan Kesehatan Anak Balita dan Faktor Penentunya di Pemukiman Kumuh Manggarai, Jakarta Selatan
Abstrak: Positive deviance has been used to describe the performance (regarding health, growth, and development) of certain children with other children in the same community and the family. The study aimed to analyze the determinants of positive deviance nutritional status and health of children under five years in slum area in Manggarai, Jakarta Selatan. The design of this study was a cross sectional study. Total sample of this study was 41 children. The study showed that there was no relation between maternal characteristics (age and education) with nutritional status and health status of children (r=0.302, p>0.05), but there was relation between nutritional status of mother (BMI) with nutritional status of children (r=0.302, p<0.05). Nutritional knowledge was related with nutritional behavior (r=0.315, p<0.05) and behavior of healthy life (r=0.530, p<0.05). Poverty, nutritional knowledge, nutritional attitudes, and nutritional behavior weren’t related with nutritional status. However, behavior of healthy life was positively and significantly related with nutritional status (r=0.330, p<0.05) and health status (r=0.381,p<0.05). Environmental sanitation wasn’t related with health status. No relationship exist between health status with nutritional status. The conclusion was that mother with good behavior of healthy life may improve children’s health 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.
