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: Kajian Positive Deviance Masalah Stunting Balita pada Keluarga Miskin di Kota Bogor
Abstrak: The objectives of the study was to analyze the Positive Deviance of stunting problems among under-five children in poor family. Design of this research was retrospective study, with 140 samples of under five children aged between 24 and 59 months from poor family in Bogor. Family socio-economic characteristics, maternal characteristics, children characteristics, maternal knowledge of nutrition and health, feeding and health patterns, pregnancy history, birth children history, breastfeeding (consumption of milk) history, children health history, and consumption patterns of children, were the factors analyzed in this study. Data were collected directly through interviews using a questionnaires, then analyzed using chi square and logistic regression. The results showed that factors significantly influence the nutritional status of under-five children in poor family based on the index TB/U are maternal education (OR = 0.236; 95%CI: 0.057–0.973), children health history (OR = 0.328; 95%CI: 0.129–0.835) and maternal employment status (OR= 3.161; 95%CI: 1.087–9.194). In other hands, the logistics regression analysis showed that pregnancy history (OR= 0.385; 95%CI: 0.169-0.879) and environmental sanitation practices (OR= 0.491; 95%CI: 0.243-0.990) were significantly influence of positive deviance. The good habits were significantly owned by group of normal children, among others: mothers who have never experienced a miscarriage, do not consume herbal medicine during pregnancy and regular pregnancy checkups. The house is always cleaned every day before the child is playing, there is the distance between the family house with neighbors, attention to cleanliness of the family toilet after being used.

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.
