Judul: Pola Asuh Makan Dan Kesehatan Pada Rumah Tangga Yang Tahan Dan Tidak Tahan Pangan Serta Kaitannya Dengan Status Gizi Anak Balita Di Kabupaten Banjarnegara, Provinsi Jawa Tengah
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: Pola Konsumsi Pangan Dan Status Gizi Anak Balita Yang Tinggal Di Daerah Rawan Pangan Di Kabupaten Banjarnegara, Jawa Tengah
Abstrak: The most basic need for a human being for its survival is food. Food consumption pattern of under-five children influenced by food consumption pattern of adult. Consumption of food have a relationship with nutritional status of under-five children directly. Under-five children is one of vulnerable groups of nutritional problem. Banjarnegara District was the one of food insecurity area in Indonesia. Household level food insecurity is generally caused by lack of livelihood opportunities and high food prices. At the individual level, aspects like consumption level of food, food taboo, education, etc. can influence the levels of food insecurity. The aim of this study was understand the correlation of food consumption pattern, food taboo and nutritional status of under-five children of household in food insecurity area in Banjarnegara District, Central Java. A cross sectional study design was applied on this study. The locations were purposively selected at two sub districts such as Pejawaran Sub District and Punggelan Sub District, in Banjarnegara District. Sample was chosen with simple random sampling which consists of 300 household with children 2-5 years old. Data collected including : household characteristic, under-five children characteristic, food consumption pattern (level consumption and food frequency consumption), food taboo and nutritional status of under-five children. Descriptive analytic was carried to all variables followed by bivariate test using Spearman correlation. Measurement of household food security in this study used household overall energy intake. In correlated analysis, household characteristic (father educational level, mothers educational level, fathers job, mothers nutritional knowledge, expenditure allocation for food and non food) was significantly positive correlated with under-five children energy and protein consumption. Food taboo have no relationship with energy and protein consumption and nutritional status by any indicators weight/age, height/age and weight/height. Household characteristic was significantly positive correlated with nutritional status by any indicators weight/age, height/age and weight/height but not with energy and protein consumption.

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.
