Judul: Analisis kerawanan pangan menurut kecamatan di Kabupaten Bogor Tahun 2011
Abstrak: This study was aimed to analyze food vulnerability problem in Bogor regency based on municipality. This study designed using retrospective by secondary data of three aspects of food security and vulnerability atlas (FSVA) such as aspect of food avaibility, aspect of food access, and aspect of food utility include policy of food vulnerability from Badan Perencanaan Pembangunan Daerah (BAPPEDA) of Bogor regency. The data processing began by calculating the three aspects of food vulnerability by WFP (World Food Programme) and DKP (Dewan Ketahanan Pangan) in 2009. The three aspects consits of nine indicators namely food production, poor household, households without access to electricity, length of damaged road, life expectancy, nutritional status, illiteracy, access of clean water and health workforce. Policy of food vulnerability was analyzed using content analysis. Bogor regency consisting of 40 municipalities and the result showed that mostly municipalities (85%) in Bogor were in secure food situation but there are six municipalities (15%) were in food vulnerability situation (composite score more than 0,8). The food vulnerability policy are support the Kebijakan Umum Ketahanan Pangan (KUKP) 2010-2014 but some institutions don’t have complete programs related to the issue of food vulnerability

Judul: Strategy, Insecure area, Food savety, Bogor Agricultural University,
Abstrak: The aims of this research are to identify the areas that are vulnerable to food and nutrition insecurity and, to find characteristics of food insecurity regions at sub district level in Bogor City. Based on that identification, the strategies to overcome the problems which is focused on food and nutrition issues are developed. The indicators used are poverty level lighth of roads, access to health facilities, Rasio of people per doctor to population density and percentage of malnourished children. All the indicators are analyzed by scoring method analysis; logistic regression analysis, satellite images analysis, AHP and spatial analysis. The research shows that there are three categories of food nutrition vulnerability: (a) vulnerable, (b) moderate and (c) food secure. There are 8 sub districts which are categorized as vulnerable; 23 sub district as moderate and 37 sub districts belong to safe status. The vulnerable areas (or food insecure regions) are characterized by the location of the sub district which are for from city center; the high percentage of the poverty population; the high percentage of malnutrition infant and poor quality of sanitations. The Other characteristics are the low capacity and facilities; and the low health service facilities and low quality of basic infrastructure. Based on the result and the analysis, the priority strategies to over come the problems of food insecure areas in Bogor city are regional economic development, community empowerment and improvement of human resources, facilities and health services, basic infrastructure, network development and strengthening coordination of among related parties and the development of environmentally friendly territory.

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.
