Judul: Konsumsi Pangan dan Gizi serta Skor Pola Pangan Harapan (PPH) pada Dewasa Usia 19-49 Tahun di Indonesia
Abstrak: This study objective to assess food consumption, NDQ, DDP scores, and the correlation between DDP and NDQ adults aged 19-49 years. Today the Desirable Dietary Pattern (DDP) scoring systim has never been used to assess the nutritional dietary quality (NDQ) of individuals, although it has been used to assess NDQ households and regions, so that DDP should be used to assess the NDQ of individuals, including adults. This study used data Riskesdas 2010 in the form of consumption data taken with the 24-hour recall method. Based on the survey results revealed that the group of grains consumed by the large number (99.4%), while the oily seeds are consumed by the smallest number (2.0%). DDP Score average adult was 53.1 ± 9.3 (54.6 ± 9.5 for men and 51.7 ± 9.1 for women). The average of the 4 food groups NDQ adults was 62.8 ± 20.6 and an average of 10 food groups NDQ adults was 51.1 ± 15.4 (52.8 ± 15.3 for men men and 59.5 ± 15.4 for women), while the average of the 14 food groups NDQ adults was 54.1 ± 16.1. DDP score and each NDQ s obtained correlation of 0.65 to 0.72, so that DDP assessment systim can be used to evaluate dietary diversity and nutritional quality of adult diet.

Judul: Konsumsi Pangan dan Gizi serta Skor Pola Pangan Harapan (PPH) pada Anak Usia 2 – 6 Tahun di Indonesia
Abstrak: This study aimed to assess food and nutrients intake, NDQ, DDP score, and the correlation between DDP score and NDQ of children aged 2-6 years. This study was carried out through analyzing a consumption data set of basic health research (Riskesdas) 2010 were collected using 24-hr recall method. Total number of children aged 2-6 years of these data was 24447 from 33 provinces of Indonesian. After applying inclusive and exclusice criterias the final subjects for this study were 16709 children. The results showed that children were most likely eat cereals (99.4%) and least likely eat oily seeds (1.6%). Children aged 2-6 years had deficiency of macronutrient energy, fats,and water. They also had deficiency of micronutrient calcium, vitamin A, vitamin B9 and vitamin C. The mean DDP score of the children aged 2-6 years was 67.1±10 (67.0±10.1 for boys and 67.3±10.1 for girls). The mean NDQ of the children aged 2-6 years was 62.4 ± 17.1 (62.6 ± 17.2 for boys and 62.2 ± 17.1 for girls). Correlation between DDP score and each of NDQ was found 0.578-0.621 that showed moderate validity result.

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.
