Judul: Analisis Efektivitas Lembaga Ketahanan Pangan di Provinsi Jawa Barat dalam Upaya Mewujudkan Penganekaragaman Konsumsi Pangan
Abstrak: Food security institution has a strategic role in achieved food diversity. The purpose of this studied to analyzed the effectiveness of food security institution in West Java province in an effort to realized the diversification of food consumption. This study used a retrospective design. Limitation agency consists of 17 SKPD food security had been coordinated under the Food Security in West Java which was in the period of 2009 and 2010 have a program related to food security. The results of this study, indicated that there was food security agencies has been good, but not effective because in 2011 PPH scores public consumption of West Java reached 73.3. Characteristics of human resources security institution still dominated high school graduates and technical employees, and the human resources do not understand the concept of development of food security. The results also showed there was from institution structure can said that was good that evidenced with jobdesc consistently with KUKP. Beside that still there was 27,8% inconsistently policies. Besides distributing of food security development budget was still not proportional, that was to the distribution subsystem budget of Rp 1,578 trillion (73.6%), whereas the consumption subsystem only Rp 8.4 billion (0.4%).

Judul: Analisis faktor sosial ekonomi dan diversifikasi pangan 26 kabupaten/kota di Provinsi Jawa Barat
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan antara faktor sosial ekonomi penduduk dengan diversifikasi konsumsi pangan. Penelitian menggunakan data sekunder yang mencakup data tingkat pendidikan; laju inflasi, pengeluaran pangan, dan estimasi pendapatan peduduk sebagai variabel bebas; serta data konsumsi sebagai variabel terikat. Rata-rata tingkat pendidikan di Jawa Barat mencapai 9.95 tahun pendidikan. Laju inflasi umum Provinsi Jawa Barat tahun 2011-2013 mengalami peningkatan sebesar 4.98%. Pangsa pengeluaran pangan di Provinsi Jawa Barat memiliki rata-rata sebesar 52.3%. Skor PPH di Jawa Barat tahun dalam tahun pengamatan hanya mencapai 69.9. Terdapat hubungan signifikan antara rata-rata tingkat pendidikan dengan skor PPH (r=0.548), laju inflasi kelompok bahan makanan dengan skor PPH (r=-0.593), pangsa pengeluaran pangan dengan skor PPH (r=-0.438). Uji Regresi Linier menghasilkan persamaan Y = -83.974+ 15.536X1 0.903X2 dengan Adjusted R² = 0.718. Tidak terdapat autokorelasi dan multikolinearitas dalam estimasi model yang didapatkan.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
