Judul: Faktor-faktor yang berhubungan dengan konsumsi pangan mahasiswa putri yang anemia dan non-anemia
Abstrak: The objectives of this research were to describe food consumption and related factors of anaemic and non-anaemic female college students. The research was a cross-sectional study and conducted in IPB’s Female Dormitory from September 2005 until March 2006. The samples were female college students who stayed at IPB’s Female Dormitory and joined IPB’s Feeding Program. There were 60 samples divided into 2 groups, anaemic group (Hb < 12 g/ dL) and non-anaemic group (Hb > 12 g/ dL). Food consumption analysis based on food frequency questionnaire and 3x24 hours food consumption recall. Study results showed that kinds of food (defined as food that were consumed > 4 times in a week by > 50% of the sample) in anaemic group were rice and tempeh, and in non-anaemic group were rice, tempeh and egg. The non-anaemic group had higher frequency in consumption of carbohydrate-food, animal protein and milk. The daily energy and protein intake in both groups were low, the iron and vitamin C intake were very low and the vitamin A intake was adequate. However, the daily intake of protein and iron in non-anaemic group was higher than it in anaemic group.

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.
