Judul: Keragaan Konsumsi Pangan, Aktivitas Fisik dan Status Gizi Narapidana di Lembaga Pemasyarakatan Paledang Bogor
Abstrak: The purpose of this study was to observed food consumption, physical activity and prisoners’s nutritional status at Paledang Prison Bogor. The design of study was cross sectional, 85 samples was collected in October 2013. The sampling technique was purposive, data was collected by questionnaire using an interview structured. The results showed that prisoners adequacy level of energy, protein, vitamin A, and Fe were categorized normal, whereas adequacy level of vitamin C, calcium, and phosphor were categorized deficit. Physical activity levels of prisoners were low category, prisoners nutritional status decrease since they stayed in prison. Chi-Square correlation test results showed there were no correlation between energy intake and protein with nutritional status, and time of detention with nutritional status (p>0.05), however there was negative correlation between physical activity with nutritional status (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.
