Judul: Pola asuh, perilaku keluarga sadar gizi (KADARZI) dan status gizi anak balita di wilayah warung anak sehat (WAS) Kabupaten Sukabumi
Abstrak: The general objective of this study was to study maternal nutritional knowledge, parenting pattern of healthy lifestyle and eating behavior, family’s nutritional behavior awarness (KADARZI), and nutritional status of children under five participants of the Healthy Kids Kiosk (Warung anak sehat=WAS) in Sukabumi District. The cross-sectional study design was used in this study that was conducted in five subdistricts of Sukabumi District i.e. Cicurug, Cisaat, Kadudampit, Kebon Pedes, and Warung Kiara on June to October 2011. The subjects in this study were chosen base on on inclusion criteria, i.e. children 1 to 5 years old, stay near by and having access to Healthy Kids Kiosk (WAS). Respondents of this study were the mothers of children under five who were choses as the subject of research. The number of samples in the study was as many as 79 children. The primary data was included the family characteristics, toddler’s characteristics, nutritional knowledge of toddler’s mother, parenting pattern of healthy lifestyle and eating behavior , consumption and KADARZI behavior and anthropometric. The consumption behavior data was collected by Food Frequency Questionair(FFQ). The results show the nutrition knowledge of mothers are good , meanwhile, healthy lifestyle and eating behavior of parenting pattern is fairly good. Mostly, KADARZI behavior is good, but the frequency of vegetables and fruits consumption is low. Availability of health facilities to support sanitation and higine in the family is fairly good. Meanwhile, we found a lack of availability of sewage disposal facilities (SPAL) since only 55.7% having SPAL. The nutritional status of children underfive was mostly normal, but still, there are undernutrition toddlers, i.e. 46.8% stunting (according to height/age index) and and 6.3% underweight (according to wight/age index). The parenting pattern of eating behavior was significantly correlated with Kadarzi behavior (p<0.01). The healthy behavior was significantly correlated (p<0.01) with parenting pattern, environment condition, and healthy status.

Judul: Hubungan Antara Praktek Perilaku HIdup Bersih dan Sehat (PHBS), Pola Asuh Makan, dan Keluarga Sadar Gizi (Kadarzi) dengan Status Gizi Balita di Kecamatan Bantar Gebang
Abstrak: Tujuan dari penelitian ini adalah untuk menganalisis hubungan antara praktik Ibu tentang Perilaku Hidup Bersih dan Sehat (PHBS), praktik pemberian makan, dan Kesadaran Gizi Keluarga (Kadarzi) dengan status gizi balita anak-anak berusia tahun. Penelitian ini berlokasi di Kelurahan Ciketing Udik, Kecamatan Bantar Gebang Kota Bekasi. Desain cross sectional digunakan dalam hal ini belajar. Jumlah sampel dalam penelitian ini adalah 72 anak balita. Uji korelasi spearman menunjukkan tidak terdapat korelasi yang signifikan antara pengetahuan gizi ibu dengan kadarzinya dan praktik pemberian makan (p>0,05). Uji korelasi spearman juga menunjukkan ada yang tidak signifikan hubungan antara praktik Kadarzi yang dilakukan ibu dengan status gizi anak (z-score berat badan per umur (WAZ), z-score panjang badan per umur (LAZ), dan z-score berat badan per tinggi badan (WHZ)) (p>0,05). Selain itu hasilnya juga menunjukkan adanya hubungan yang signifikan antara praktik PHBS ibu dengan status gizi (z-score berat badan per umur (r=0,232; p=0,050) dan z-score panjang badan per umur (r=0.362; p=0.002)) dan praktik pemberian makan dengan status gizi (z-score panjang badan per umur (r=0.253; p=0.032)).

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.
