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: PEngaruh Akar Gingseng (Wild ginseng) dalam Ransum Mencit (Mus musculus) terhadap Jumlah Anak dan Pertumbuhan Anak dari Lahir sampai dengan Sapih
Abstrak: Ginseng merupakan tanaman herbal alami yang memiliki bahan aktif flavonoid dan ginsenosid yang bermanfaat dalam memelihara diri dari penyakit, meningkatkan daya tahan tubuh dan merangsang pembentukan hormon estrogen pada mamalia. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh akar ginseng terhadap jumlah anak dan pertumbuhan anak mencit dari lahir sampai dengan sapih. Penelitian ini dilaksanakan sejak Juli sampai dengan September 2005 di kandang A Fakultas Peternakan, Institut Pertanian Bogor. Mencit yang digunakan adalah mencit yang sudah dewasa tubuh berumur dua bulan sebanyak 48 ekor masing-masing 24 ekor betina dan 24 ekor jantan. Perkawinan dilakukan dengan perbandingan satu jantan dengan satu betina yang dimasukkan ke dalam kandang kawin. Rancangan yang digunakan adalah rancangan acak lengkap (RAL) dengan empat taraf perlakuan yaitu R1 (kontrol), R2 (0.0134 % ginseng), R3 (0.026 % ginseng), dan R4 (0.04 % ginseng). Data dianalisis dengan sidik ragam (Anova), jika berbeda nyata maka dilanjutkan dengan uji Duncan. Peubah yang diamati adalah jumlah anak per kelahiran, bobot lahir, pertambahan bobot badan anak dan bobot sapih.

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.
