Judul: Analisis Penyelenggaraan Makanan, Tingkat Kesukaan dan Sisa Konsumsi Pangan Narapidana di Lembaga Pemasyarakatan Paledang, Bogor
Abstrak: The purpose of this study was to analyze the food service, preference level and prisoner’s residual of food consumption at Paledang prison Bogor. The design of study was cross sectional, 85 sampel was collected in October 2013. The food service consist of inputs (human resources, space processing, raw materials and funds), the process (menus planning, ordering and purchasing of groceries, grocery receipted, processing, presentation and distribution, recording and reporting, sanitation and hygiene), and output (food availability). The food service at prison Paledang was not good enough and has not complied the standard. The menus of preference level of food consumption are presented belong like and neutral categorized. The residual of food consumption level ranged from 7-63%. Statistical test result showed no significant correlation between individual characteristics of the prisoners with the preference level of food consumption (p>0.05).

Judul: Analisis Penyelenggaraan Makanan, Konsumsi Pangan dan Status Gizi Narapidana di Lembaga Pemasyarakatan Kelas I Cirebon
Abstrak: Tujuan penelitian ini adalah untuk menganalisis penyelenggaraan makanan, konsumsi pangan dan status gizi narapidana di lembaga pemasyarakatan Kelas I Cirebon. Penelitian ini menggunakan desain cross sectional study dengan cara pengambilan sampel secara purposive sebanyak 35 orang dilaksanakan pada bulan Juni 2015. Penyelenggaraan makanan terdiri atas input (tenaga, dana, fasilitas, bahan makanan dan prosedur), proses (perencanaan menu, pengolahan, dan distribusi) dan output (konsumsi pangan dan status gizi). Proses penyelenggaraan makanan di Lapas Kelas I Cirebon masih belum memenuhi ketentuan penyelenggaraan makanan terutama dalam hal sanitasi dan higiene. Tingkat kecukupan energi sampel (57.14%) berada pada kategori defisit berat dan protein (34.3%) berada pada kategori normal. Sampel berada dalam kategori status gizi normal (45.7%) dan lebih (51.4%). Hasil uji hubungan Chi-Square menunjukkan bahwa tidak terdapat hubungan antara tingkat kecukupan energi dan protein dengan status gizi sampel (p>0.05).

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.
