Judul: Suplementasi Ginseng Liar (Wild ginseng) pada Ransum Terhadap Pertumbuhan Mencit (Mus musculus)
Abstrak: The aim of the research was to know effectiveness of supplementation of wild ginseng on growth of male and female mouse (Mus musculus). This research used completely randomized design with four treatments and six replications and used one mouse for each replication. The diet treatments were R1 = control diet (without ginseng), R2 = R1+0.0134% ginseng, R3 = R1+0.026% ginseng and R4 = R1+0.04% ginseng. The parameters measured were, dry matter intake, organic matter intake, crude protein intake, crude fiber intake, body weight gain, feed convertion and mortality. Data were analyzed with analyse of variance (ANOVA) and significant differences were further tested using orthogonal contrast test. The results showed that the treatments did not significantly affect (P>0.05) to dry matter intake, organic matter intake, crude protein intake, body weight gain, feed convertion and mortality except to crude fiber intake (P<0,01) which significantly affected.

Judul: Pertumbuhan mencit (Mus musculus) lepas sapih (umur 21 hari) sampai umur 42 hari yang mendapat pakan tambahan kemangi (Ocimum basilicum) segar
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.
