Abstrak: DATA PUTRA S. B04050439. The Effect of Ethanol Extract of Curcuma Zedoaria Rhizome on Clinical Signs in Rabbit during the formed process of Mammary Neoplasm which Induced by Methyl-N-Nitrosourea. Under Recommendation of GUNANTI and RINI MADYASTUTI. The aim of this research was to determine the effect of ethanol extract Curcuma zedoaria on clinical signs in rabbit (Oryctolagus cuniculus) during the formed process of mammary neoplasm which induced by Methyl-N-Nitrosourea. Nine rabbits were divided into three groups. First group was untreated which used as control group and also not Induced by Methyl-N-Nitrosourea, the second group was positive control which induced by Methyl-N-Nitrosourea 50 mikrogram/kg BW and gave curcumin 60 mg/kg BW treatment, the third group was induced by Methyl-N-Nitrosourea and treated with extract ethanol of Curcuma zedoaria rhizome 250 mg/kg BW each rabbit. The result showed that extract ethanol can keep the body temperature 39.23±0.59, heart rate 133±8.22 still in normal range in rabbit which induced by Methyl-N-Nitrosourea and given extract ethanol of Curcuma zedoaria rhizome and curcumin Key words : Curcuma zedoaria, Extract, Rabbit, Clinical Signs, Methyl-N-Nitrosourea

Judul: Pengaruh Pemberian Ekstrak Etanol Rimpang Temu Putih (Curcuma zedoaria (Berg.) Roscoe) Terhadap Jumlah Dan Diferensiasi Leukosit Pada Kelinci Yang Diinduksi Tumor Dan Diterapi Dengan Operasi
Abstrak: The objective of this research was to observe the profile of rabbit leococytes which was induced by tumour and treated by combination of surgery (ovariohisterectomy and mastectomy) with ethanolic extract of zedoary rhizome (Curcurna zedoaria (Berg.) Roscoe): preventive; curative; preventive and curative. Twenty one rabbits were used in this research, divided into seven groups: negative control, preventive and curative of curcumin, positive control, surgery, preventive of ethanolic extract of zedoary rhizome, preventive and curative of ethanolic extract of zedoary rhizome, and curative of ethanolic extract of zedoary rhizome. The blood collection was done every week for 9 weeks. The tumour was induced on second quarter of mammary gland by n-methyl-nnitrosourea (MNU) every week for 3 weeks. The ethanolic extract of zedoary was given daily for 4 weeks (preventive; curative) and 8 weeks (preventive and curative). The surgery was done in the fifth week. The result showed that the total leucocyte, neutrophil (heterophil), eosinophil and basophil count increased before surgery. On the other hand, the total leucocyte, neutrophil and lymphocyte count decreased after the administration of ethanolic extract of zedoary rhizome.

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.
