Judul: Food Coping Strategy Rumah Tangga Yang Tinggal Di Wilayah Rawan Pangan Dan Gizi Kabupaten Banjarnegara, Propinsi Jawa Tengah
Abstrak: According to Food Insecurity Atlas, Banjarnegara is included of insecurity food area. In this area, there are food security household and food insecurity household. Food insecurity household is need the strategy to maintain the food intake. The general objective of this study is to analyze household food coping strategy in food insecurity area, Banjarnegara, Central Java. The specific objectives are to identify sosio-economic characteristics of household, to identify history of food insecurity in food security and food insecurity household, to analyze correlation of food coping strategy level with socio-economic characteristics of household and levels of household security. A descriptive analytic study with cross sectional approach was conducted on 2 areas (Pejawaran and Punggelan) of Banjarnegara. Sample was chosen with simple random sampling which consists of 300 household with children 2-5 years old. Data collected include : socio-economic characteristics of household, history of food insecurity,household food coping strategy, level of household food security, and nutritional status of under-five children. Descriptive analytic was carried to all variables followed by bivariate test using Spearman correlation. In correlated analysis, sosio-economic characteristics (parents education level, total of expenditure ), was significantly negative correlated with level of food coping strategy. The age of mother was significantly positive correlated with level of food coping strategy. Level of household food security was significantly negative correlated with level of food coping strategy.

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.
