Judul: Analisis Situasi Ketahanan Pangan dan Gizi Kota Tangerang Periode Tahun 2008-2011
Abstrak: The study is aimed to analyze food and nutrition security of Tangerang City consisted of food supply, distribution, consumption, and nutritional status during the period of 2008-2011.In common, Tangerang City food supply equal to energy in the period of 2008-2011 was fulfill the WNPG recommended dietary allowance, however its decrease in the latest year. Despite of no food storage held by the local government of Tangerang City yet, BULOG Sub Divre Tangerang manage government rice stock that can be used by local government whenever needed to be released in the market during rice shortage. In general food distribution in Tangerang city is stable as indicated by low coefficient of variance of desicable food price. Quality of food consumption is remained a serious problem since the dietary pattern score (PPH score) in 2011 was only 77.3 and energy adequacy level 97.70%. Local government survey found that 33.3 % of selected food marketed were not comply the regulation regarding uses of hazardous subtances added to food such as borax, formalin and textile colorant. Under nutrition prevalence reach 12.6% which was lower than MDG’s target of 18.5% in 2015, but in some villages under nutrition are still prevalent an the prevalence was higher than MDG’s target

Judul: Analisis Pencapaian Standar Pelayanan Minimum (SPM) Ketahanan Pangan dan Gizi Kota Tangerang pada Tahun 2011
Abstrak: The objective of this research is to identify the problem of food and nutrition security at Tangerang City and evaluate the achievement of Minimum Service Standards (MSS) in 2011. This is descriptive analysis study. Secondary data which collected within period September to November 2012 and data used were obtained from various offices at the local government of Tangerang City. The indicators used to analyze the achievement of SPM consist of Food Security and Nutrition, including availability of energy and protein per capita, strengthening food reserves, availability of information supply, prices and access to food in the area, price stability and food supply, achieving a score of PPH, food safety supervision and guidance and handling of food-insecure areas. Four out of seven indicators were exceed the minimum service standar, while others hasn’t reach target in 2015. Four indicator which exceed MSS target in 2015 are availability of energy and protein per capita, availability of information supply, prices and access to food in the area, food safety supervision and guidance andhandling of food-insecure areas

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.
