Abstrak: Ocimum basilicum is one of the vegetables which has a drug effect. The chemical composition are quite complete and profitable for body health, such as boron and stigmasterol which can influence activity of reproduction hormones. This research aimed to study growth pattern of mice from post weaning up to adult, which were given various levels dry Ocimum basilicum in their feed. This research had been done for two months, since middle of July until the first week of September 2005. The materials were 30 heads of males and 60 heads of females as parents, with 150 heads of males and 136 heads of females of a post weaning age kids. Feed were given at 15.00-17.00 WIB. The Observation variables were weaning weight 42 days body weight, body weight gain, feed consumption and feed conversion. The research used Completely Randomized Design with nested pattern 2x3 and Tukey test. The result showed that 5,0% dry Ocimum basilicum supplementation had a higher level of weaning weight, body weight gain, weight at 42 days old and feed consumption than 0 and 2,5%. Supplementation of 2,5% dry Ocimum basilicum had a higher level of feed conversion then 0 and 5,0%. Male mice has a higher level of weaning weight (at 5,0%), body weight gain at 30 and 36 days, weight at 42 days old, and consumption on 0 and 2,5% at third week and 5,0% at second week than females. Feed consumption and conversion did not influence by level of treatments.

Abstrak: Ocimwn basilicum is one of the vegetables can be use as a herbal medicine duet It can be use to stimulate the esmgen and testosterone hormone. The aim of tiis research was to studied the information of fksh Ocimwn basilinan supplementation in diet in post weaning mice growth (21-42 days old). Materials of the research were 90 (60 heads of female and 30 heads of male) with 264 heads of a post weaning mice. The experimental design was nested design with 2 factors and ten repetitions. The first factor have 3 levels supplementation (control; 2,s and 5,0%) of fiesh Ocimwn hilkxm and the second factor \\,ere sex (male and fcmale) within each level of factor fi-esh Ocimwn basilicum. The variables to be observed were weaning weight, 42 days old weight, body weight gain, feed consumption and conversion. The analysis result shown tfiat supplementation of b h Ocimum basilicum at 5,0% level significantly decrease weaning weight mice (P<0,01) and 42 days body weight (P<0,05) compared control and 2,5% leveL At 2,5% level feed consumption higher (P<0,05) than 5,Wh level, but control not different witb 2,s and 5,0% levels. Sex within each level of treatment affected 42 days old weight, body weight gain and feed conversion. Keywords: mice (Mu musculus), Ocimum barilicum, grow& rate

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.
