Judul: Determinants Factors of Stunting in Children 24-59 Month in Indonesia
Abstrak: Age under five year old is one of the most important periods for a child’s growth and development. This period is important for placing health and intelectual development for a child’s future. Based on that, nutrition problems in childhood are needed to be eliminated. There are many problems in childhood related to nutrition .According to Ministry of Health (2008), there are 36,8% of children were stunted. It is larger than the number of undernourished and wasted children. The objective of this study were : (1) study the family characteristics, infectious diseases, environmental sanitation, hygiene behaviour, access and healthcare utilization, parents’ height and nutritional status according to height-for-age in children; (2) to analyze the relationship between environmental sanitation and healthcare utilization, and between hygiene behaviour and infectious diseases; and (3) to analyze determinant factors of 24-59 months old stunted children. This study used secondary data taken from Basic Health Research 2007 with cross sectional design. Sample size of 42042 children were taken. Pearson’s correlation were used to test relationship among variables. Determinants factors were revealed using SAS program with stepwise method. The results showed that there was a significant relationship (p<0,05) between infectious diseases and sanitation; among infectious diseases and access and healthcare utilization and hygiene behaviour. Factors affecting stunting significantly (p<0,05) were father’s height, mother’s height, age, gender, neighborhood, social and economic status, mother’s education, infectious diseases, personal hygiene, and environmental sanitation.

Judul: Risk Factors of Stunting Among School-aged Children
Abstrak: Based on the results of Indonesian Basic Health Research in 2010, the national prevalence of stunting among school aged children (6-12 years old) was 35.6%. Stunting is a major public-health problem in low and middle-income countries because of its association with increased risk of mortality during childhood. Stunting also leads to significant physical and functional deficits among survivors (The Lancet 2008). Stunting affects the development of cognitive processes during school-aged period (Kar et al. 2008). Several studies have shown that during school-aged period, children was less experienced catchup growth or remain stable even experienced stunting (Friedman et al. 2005). Health Research and Development Agency of the Indonesian Ministry of Health has conducted a Basic Health Research at national scale in 2010 that could potentially be analyzed to determine the risk factors for stunting in school-aged children. Therefore, the objective of this study was to analyze risk factors of stunting among school-aged children. Specifically, objective of this study as follows: (1) identify the characteristics of the children and families of stunted and normal children, (2) identify health and environmental sanitation in stunted and normal children, (3) identifying the incidence of infectious diseases (malaria) in stunted and normal children, (4) analyzing the quantity and quality of food consumption in stunted and normal children and (5) analyze factors that influence the incidence of stunting in the children. This study used secondary data from Basic Health Research by Health Research and Development Agency of the Indonesian Ministry of Health in 2010 with a cross-sectional study design. The data analyzed in this study were from eight Provinces which selected according category of prevalence of stunting (WHO 1997), were very high (≥ 40%) in East Nusa Tenggara and North Sumatra, high (30-39%) in West Nusa Tenggara and West Java, moderate (20-29%) in Bangka Belitung, Jakarta and Yogyakarta, and low (<20%) in Bali. Processing and data analysis was conducted in June-October 2013. Subjects of this research are boys and girls aged 6-12 years from eight provinces. Number of subjects contained in the electronic files was 11335 children. After a cleaning process, the number of children analyzed was 8710. Analysis data used Microsoft Excel 2007 and SPSS for Windows version 17.0. The t test and oneway ANOVA was used to determine mean difference of variable with data continues and mean HAZ. Chisquare test was used to determine relationship between independent variable with stunting. Multivariate analyzes were performed using logistic regression with Backward Wald method with statistical significance criteria of p<0.05, and the value of the confidence interval (CI) of 95%. Prevalence of stunting in eight provinces was 28.11 % and 11.38% were categorized as severe stunting. Stunted children were higher in older children (10- 12 years), male, mother with short stature (<145 cm), parents with low education levels (≤ primary school), father who smoking, mother with a low BMI and father 6 with normal BMI, children with ≥ 8 family member, low household expenditure (quintiles 1 and 2), and living in rural areas. There were significant relationship between children with older age (10-12 years), male children, low maternal height (<145

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.
