Abstrak: The aim of this research is to find out the influence of the red fruit extract (RFE) in the blood picture, liver and kidney of mice which induced quinine. Twenty five mice were divided into 5 groups; the groups are No (normal), the group K (quinine), the S1 (quinine and SBM 0,9 ml / kg BB/day), S2 groups (quinine and SBM 1,8 ml/ kg BB/day) and the S3 (only RFE dosage of 0,9 ml/kg BB/day). The blood sampling were done in the 0, 3rd, 7th, 10th, 14th, 17th, 20th, 23rd and 29th day. Nekropsi was done after the RFE was stopped. Liver and kidney organs were retrieved and processed into histopathology preparate with Haematoxylin-Eosin (HE) coloring. Histopathology examination was done for each group, by 20 observation of field perspective and the result were counted to get the average. Profile of blood does not change. Giving red fruit extract can increase the number of thrombocyte although statistically it was not significant (P>0,05). The damage of liver which caused by quinine, for instance hidropis degeneration, edema, and nekrosa were retarded by RFE treatment with dosage 0,9 ml/ kg BB/ day. The damage in kidney which caused by quinine (hidropis degeneration on tubuli cells, edema glomerulus, and the expansion lumen tubuli) was also retarded by the treatment. Degeneration of hidropis and nekrosa can expand in kidney with 1,8 ml/kg BB/day RFE.

Judul: Pengaruh Pemberian Ekstrak Tumbuhan Obat Antimalaria  Quassia indica Terhadap Toksikopatologi Organ Hati dan  Ginjal Mencit (Mus musculus).
Abstrak: The aim of this research was to study the toxicopathology effect of Quassia indica act of distributing with various level doses in the liver and kidney of mice (Mus musculus). 25 mice (Mus musculus) separated into 5 groups which were adapted for two weeks before using in this experiment. Four groups were received Quassia indica extract at various level doses, of 1, 10, 100, and 1000 mg/kg body weight, and one group of mice acted as control which received with Carboxymethocellulose (CMC-Na). After receiving Quassia indica for seven days the mice then were euthanized with over dose of ether. The liver and kidney were taken and samples fixated in Buffer Neutral Formalin 10% solution for 48 hours then the making of histopathology slides. Histopathology slides stained with Haematoksilin Eosin and observed with video-photo microscope. In the liver, observation was founded the cell with degeneration and apoptotic around vena porta and vena centralis, and in the kidney was founded degeneration and apoptotic of tubule epithelium, glomerular atrophy and protein sedimentation. Based on the result and analized with statistic method can be concluded that the distribution of Quassia indica extract with 1000 mg/kg BW doses could emerge a significant lesion on the liver and kidney of mice (Mus musculus).

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.
