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: Analisis Kerawanan Pangan di Tingkat Kecamatan Kota Bogor
Abstrak: Pangan merupakan kebutuhan dasar manusia agar dapat hidup dan beraktivitas. Kondisi terpenuhinya kebutuhan ini dikenal dengan istilah ketahanan pangan. Rawan pangan atau ketidaktahanan pangan merupakan suatu kondisi tidak tersedianya pangan yang cukup, baik jumlah maupun mutunya, aman, merata dan terjangkau. Gizi buruk pada balita merupakan masalah pangan dan gizi yang menjadi outcome situasi ketahanan pangan wilayah. Kondisi Kota Bogor yang tahan pangan seharusnya masalah tersebut tidak terjadi. Keadaan ini menunjukkan bahwa ketahanan pangan merupakan masalah yang kompleks dan perlu analisis mendalam. Saat ini belum ada klasifikasi tingkat kerawanan pangan di Kota Bogor untuk mengantisipasi kondisi rawan pangan. Penelitian ini bertujuan untuk menganalisis situasi kerawanan pangan di tingkat kecamatan Kota Bogor, menganalisis kesesuaian intervensi dengan situasi kerawanan pangan, dan menyusun rekomendasi jenis intervensi pangan. Data dianalisis secara deskriptif, kemudian diklasifikasikan ke dalam enam kategori yaitu sangat rawan, rawan, agak rawan, cukup tahan, tahan dan sangat tahan. Pengkategorian tersebut berdasarkan dua indikator kerawanan pangan yaitu akses pangan dan kesehatan. lndikator yang digunakan dalam analisis kerawanan pangan disesuaikan dengan indikator FIA (Food Insecurity Atlas) yang digunakan WFP (World Food Programme 2003) dalam analisis kerawanan pangan nasional

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.
