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: 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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
