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: Ketersediaan, Kecukupan Dan Konsumsi Pangan Penduduk Propinsi Daerah Tingkat I Nusa Tenggara Barat
Abstrak: Penelitian ini bertujuan untuk mengetahui tingkat ketersediaan dan tingkat konsumsi pangan menurut standar kecukupan penduduk Propinsi Nusa Tenggara Barat. Semua data yang dikumpulkan dalam penelitian ini merupakan data sekunder. Data produksi pangan, perubahan stok akhir tahun, pangan masuk dan keluar daerah diperoleh dari dinas/instansi yang mencatat data tersebut. Sedangkan data konversi beberapa jenis pangan, data persentase penggunaan pangan dalam daerah dan yang tercecer, data pro- porsi penduduk Nusa Tenggara Barat dan data tinggi badan rata-rata diperoleh dari beberapa pustaka dan data konsumsi pangan penduduk Nusa Tenggara Barat diperoleh dari hasil SUSENAS tahun 1984. Hasil pengolahan data disajikan dalam bentuk tabel ketersediaan (Tabel Neraca Bahan Makanan), tabel kecukupan dan tabel konsumsi. Dalam membandingkan jumlah ketersediaan, kecukupan dan konsumsi pangan penduduk per orang per hari digunakan cara pendekatan analisa energi dan protein, kemudian dibahas secara deskriptif. Dari hasil penelitian diperoleh angka ketersediaan energi dan protein per orang per hari penduduk Propinsi Nusa Tenggara Barat yaitu sebesar 2 709 Kalori atau 146.12% B dari standar kecukupan (1 854 Kalori) dan 69.90 gram protein atau 132.66% dari standar kecukupan (52.69 gram).

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.
