Judul: Hubungan Status Anemia, Tingkat Kecukupan dan Status Gizi dengan Siklus Menstruasi pada Wanita Vegetarian.
Abstrak: Penelitian ini bertujuan menganalisis hubungan status anemia, tingkat kecukupan dan status gizi dengan siklus menstruasi pada wanita vegetarian di Bogor. Desain penelitian ini adalah cross sectional study dengan 30 contoh dari Komunitas Vegetarian di Bogor dengan 5 jenis vegetarian yaitu vegan (n=6), lacto (n=4), lacto ovo (n=14), ovo (n=1) dan pesco (n=6). Status anemia contoh diketahui berdasarkan kadar hemoglobin menggunakan HemoCue. Rata-rata kadar hemoglobin vegan, pesco dan lacto ovo vegetarian cenderung normal namun rata-rata kadar hemoglobin contoh lacto dan ovo vegetarian tergolong rendah. Hasil uji korelasi menunjukkan bahwa tidak terdapat hubungan yang signifikan antara status gizi dengan status anemia contoh (p>0.05). Sebagian besar (93.3%) contoh memiliki siklus menstruasi yang tergolong normal. Sebesar 6.7% contoh yang mengalami gangguan siklus menstruasi tidak mengalami anemia, akan tetapi pada tingkat kecukupan gizi secara keseluruhan tergolong defisit. Hasil uji korelasi Spearman menunjukkan bahwa tidak terdapat hubungan yang signifikan antara status anemia dengan siklus menstruasi (p>0.05).

Judul: Pola Konsumsi dan Status Gizi pada Kelompok Vegetarian di Kota Bogor
Abstrak: The objective of this study was to analyze consumption patterns and nutritional status of vegetarian groups in Bogor. The study used cross sectional design and study participants were recruited purposively. The number of subjects was 42 vegetarian consisted of 22 men and 20 women. The result showed that nutritional adequacy level of energy of the vegetarian groups experienced deficiency of men (50%) and women (60%). Nutritional adequacy level of protein of the vegetarian groups of men experienced deficient (59%) and women (65%). Nutritional adequacy level of fat of the vegetarian groups experienced a shortage of men (52%) and women (48%). Nutritional adequacy level of carbohydrates of the vegetarian groups were good of men (64%) while women were deficient (75%). Nutritional adequacy level of vitamins and minerals of the vegetarian groups experienced a shortage of men (100%) and women (100%). The Spearman statistical analysis showed that there was no correlation (p>0.05) between type of vegetarian (vegan, lacto vegetarian vegetarian dan lacto-ovo vegetarian vegetarian) and old vegetarian with the level of recommended dietary allowance.

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.
