Judul: Analisis Ketersediaan Pangan Kabupaten Cirebon Propinsi Jawa Barat Tahun 2012
Abstrak: This study aims to analyze the food availability in Cirebon district, West Java in 2012. This research was conducted in July until November 2013. The source of processed data is collected from relevant agencies in Cirebon District 2010-2012. The result show that nearly 50 % kind of food in the Cirebon District increased production in 2011-2012, but energy needs inhabitant not fulfilled through domestic production (77.2 %). Cirebon District are able to meet 50 % of energy needs of its inhabitants of production of food sources of carbohydrate low (surplus). In general (55 %) the ratio of swasembada was in the category of good. The level of food availability in Cirebon District in 2012 has met the SPM. It is ideal for the availability of energy at 2 489 Cal/cap/day (113.1%) and 82.7 g/person/day (145.1%) for protein. Food composition as measured by a score of PPH in Cirebon District has reached in 89.5, Cirebon District should improve PPH score 2.1 points per year. Food production needs in 2017 of groups tubers, meats, oils and fats, fruits/nuts and nuts production should be increased by 18.6 tons/year,8.7 tons/year, 1.1 tons/ year, 8.6 tons/year, 1.6 tons/year each year.

Judul: The Analysis of Food Consumption in West Java Province
Abstrak: Tujuan penelitian ini adalah menganalisis ketersediaan pangan; karakteristik sosiodemografi; karakteristik ekonomi; dan situasi konsumsi pangan; serta hubungan antara ketersediaan pangan, karakteristik sosiodemografi, dan karakteristik ekonomi dengan konsumsi pangan penduduk Provinsi Jawa Barat. Tidak terdapat kabupaten/kota yang mencapai skor PPH ketersediaan pangan ideal sebesa 100. Beberapa wilayah termasuk padat penduduk seperti Kota Bogor, Kota Bandung, Kota Bekasi, dan Kota Depok. Rata-rata lama sekolah di kabupaten/kota belum ada yang memenuhi program pemerintah wajib belajar 12 tahun. Pengeluaran pangan penduduk, tingkat kemiskinan serta harga pangan di setiap kabupaten/kota tidak merata. 17 kabupaten/kota termasuk TKE cukup dan 10 kabupaten/kota termasuk TKE lebih. 10 kabupaten/kota termasuk TKP cukup dan 17 kabupaten/kota termasuk TKP lebih. Tidak ada kabupaten/kota yang mencapai skor PPH 100. Uji korelasi menunjukkan bahwa terdapat hubungan searah antara TKE ketersediaan(p<0,01) dan tingkat kemiskinan (p<0,05) dengan TKE konsumsi. Terdapat hubungan tidak searah antara rata-rata lama sekolah (p<0,01) dan harga minyak (p<0,01)dengan TKE konsumsi. Terdapat hubungan searah antara pengeluaran pangan (p<0,05) dengan skor PPH konsumsi. Tidak terdapat hubungan antara ketersediaan pangan, jumlah penduduk, rata-rata lama sekolah, pengeluaran pangan perkapita, harga pangan dan tingkat kemiskinan dengan TKP konsumsi.

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.
