Abstrak: The objective of this study was analyze the relationship between eating pattern, food consumption and nutritional status of children from poor households. This study used cross sectional study design with 83 children under five years old as subject. Study was conducted in Cadasari and two subdistrict were selected in February to March 2014. Descriptive analysis showed that eating pattern of mothers (57%) categorized as medium. Dietary diversity score of subject categorized as medium. The level of suffeciency of energy as many as 89%, while the level of suffeciency of protein as many as 97%. Nutritional status of subject 88% categorized as normal and 12% were underweight. The Spearman test showed that educational status with nutrition knowledge of mothers had significant correlation (p<0.05), the test also showed that income had significant correlation with dietary diversity score (p<0.05). The Chi-Square test showed a positive correlation between nutrition knowledge and eating pattern (p<0.05), the test also showed that income had positive correlation with protein sufficiency (p<0.05). The study showed that parenting had significantly affect to the nutritional status of children with odd ratio 1.20.

Abstrak: This study aimed to analyze the impacts of parenting practices (feeding and home health practices) on underfive children’s nutritional status in different level of household food security. The study design was a cross-sectional study. The locations were purposively selected at the rural food insecure area in Banjarnegara (Kecamatan Pejawaran and Kecamatan Punggelan). Total samples of the study were 300 children and their families. Data on parenting practices were collected through personal interviews used questionnaire and nutritional status was calculated by using WHO-NCHS z-score. The study showed that 37.3 percent of households were categorized as very food-insecure, while 31.7 percent and 31.0 percent categorized as food-insecure and food-secure, respectively. The average scores of feeding and home health practices among samples were categorized as low (49.0%) and middle (73.1%) respectively, and children of group very food-insecure had the lowest score of parenting practices. There was a significantly difference among the groups in the scores of sample’s feeding practices. The study showed that about 86 percent of children were categorized as normal (BB/TB indicator), but there were 11.6 percent categorized as wasting, while 32.0 percent and 54.3 percent categorized as underweight and stunting, respectively. Statistical analyses showed significant difference in term of nutritional status. There was a significant correlation between child’s nutritional status (BB/U and TB/U) and home health practices, and between child’s nutritional status (BB/U, TB/U and BB/TB) and household food security. The study showed that child’s nutritional status (TB/U) was influenced by feeding practices, home health practices, household food security and father’s occupation.

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.
