Judul: Kontribusi Raskin terhadap Total Konsumsi Beras dan Tingkat Kecukupan Gizi pada Rumah Tangga Miskin di Bogor.
Abstrak: The aim of this study was to analyze contribution of Rice for the Poor (Raskin) to total rice consumption and nutritional adequacy on poor households in Bogor. Design study used cross sectional study and it was done in Kabupaten and Kota Bogor. There were 98 poor households which listed as Rumah Tangga Penerima Manfaat (RTS-PM) Raskin chosen randomly as samples. Result of this study showed that average amount of Raskin which received by households were 5.8 kg/hh/month (2.8 kg in Dramaga, 2.4 kg in Leuwiliang, 9.0 kg in Bogor Selatan). Average of households Raskin consumption were 40.4 gram/capita/day, despite of total households rice consumption were 234.6 gram/capita/day (221.4 gram in Dramaga, 255.9 gram in Leuwiliang, 230.1 gram in Bogor Selatan). Contribution of Raskin for total households rice consumption (7.0 kg/capita/month) were 17.2%. Total Raskin which received by household only could provide household rice consumption for 9.5 days. If Raskin fortified with 80 ppm iron, 30 ppm zinc, 6.4 ppm thiamine, 1.3 ppm folic acid, 0.01 ppm vitamin B12, and 53 ppm niasin were estimated to increase micronutrients contribution of iron 20.0%, thiamine 17.8%, vitamin B12 14.8%, niasin 13.9%, folic acid 12.9%, and zinc 10.4% respectively.

Judul: Kontribusi Terigu terhadap Kecukupan Gizi Rumah Tangga Miskin di Wilayah DKI Jakarta
Abstrak: National Economic and Social Survey during the periode of 2002-2008 indicated the important of wheat flour as the second staple food after rice. Mandatory fortification of wheat flour was expected to improve the community nutritional status, especially poor households, but evaluation regarding the impact is remained limited. The aim of the study was to analize the contribution of wheat flour to the nutritional adequacy of poor households. This was a cross sectional study. The result of the study showed the wheat processing food that gave significant contribution to the wheat flour and micro nutrient intake were instant noodles, sweet breads, and fried foods. The average of wheat consumption among the sample households was 42.35 gram per capita per day that gave contribution to the adequacy of energy, protein, iron, zinc, vitamin B1, vitamin B2, and folic acid as follows; 7.7%, 7.2%, 3.4%, 2.9%, 4.1%, 2.7%, and 1.1%. Wheat flour fortification was expected to increase the contribution of micro nutrients iron, zinc, vitamin B1,vitamin B2, and folic acid as follows; 17.4%, 13.9%, 14.3%, 18.0%, and 24.5%.

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.
