Judul: Kualitas Makanan Selingan Pagi Anak Prasekolah pada Pendidikan Anak Usia Dini (PAUD) Bougenvil Kota Bekasi
Abstrak: Quality of food can be identified from (1) the contribution of the energy content and protein of food to RDA, and (2) diversity/variety of food. The purpose of this study was to analyze the quality of provision and consumption of meal box or snack of preschool children. This study used a case study design. A total of 42 children studied purposively. Data were collected by direct interview using questionnaires and 2x24 hour recall method. Nutrition contribution of meal box to RDA were 14% of energy, 21% of protein, 17% of vitamin A, 9% of vitamin C, 22% of iron (Fe), and 21% of calcium (Ca). Nutrition contribution of snack to RDA were 13% of energy, 8% of protein, 2% of vitamin C, 9% of iron (Fe), and 10% of calcium (Ca). There were no significant corelation between maternal nutrition knowledge in behavior terms of providing meal box or snack and nutritional knowledge with attitude (p>0.05). There were significant corelation between behavior terms of providing meal box or snack with attitude (p<0.05),and significant corelation between the level of adequacy of energy and protein with nutrition status (p<0.05). No significant corelation between the level of maternal education and nutritional status sample (p>0.05). There were no significant corelation between socio-economic families, education of respondents, the nutritional status of a sample with an interlude diet quality (p>0.05). Conclusion: Quality of brunch (meal box or snack) samples are generally not qualified as yet to meet the energy contribution of 150-200 kcal and 4.0-5.0 grams of protein (10-13% RDA), as well as the diversity of sources which include energy substances, substances builders, and regulating substances.

Judul: Riwayat pemberian makan, status gizi dan status kesehatan siswa paud
Abstrak: General objective of this study was to analyze history of eating, nutritional and health status of PAUD students. The study was conducted from November to Desember 2011 in PAUD Cikal Mandiri and PAUD Dukuh, North Bogor Municipality. The study using crossectional design with total samples of 55 PAUD students. Samples were chosen purposively, with criterias: aged 2-4 years old, breastfeed at least 4 month, having health card (KMS) and attending PAUD centre. Primary datas consisted of characteristics of children and mother, history of eating, food consumption, weigth and height, and morbidity data. Secondary datas were gathered from children health card (KMS) namely weight at 1-12 month and occurrance of immunization, and children attendence at PAUD center. Nutritional status was negatively related to children age (r=0,301, p=0,025), but positively related to level of energy adequacy (r=0,320, p=0,017) and nutritional status at 1-12 month (r=0,376, p= 0,000). Health status was negatively related to mother age (r=-0,284, p=0,036) and negatively related to history of exclusively breastfeeding (r=-0,266, p=0,050). Nutritional status was influenced by nutritional status at 1-12 month (r=3,667, p=0,001), while health status was influenced by mother age (r=-2,340 p=0,023) and history of exclusively breastfeeding (r=-2,460, p=0,017).

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.
