Judul: Pertumbuhan mencit, Mus musculus umur 21 sampai dengan 42 hari yang mendapatkan bahan pakan tambahan kemangi, Ocimum basilicum kering
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.

Judul: Ukuran organ reproduksi dan kualitas sperma mencit (Mus musculus) yang mendapat bahan pakan kemangi (Ocimum basilicum L.) kering
Abstrak: Kemangi (basil: Ocimrrm basilicrrm L.) is \itell known as a traditional medicine plant wich is used to increase reproduction ability. It has been discovered that basil has a group of beneficial chemical compound to induce the bcdy respon, especially to the reproductive orsan. This research was conducted to study the pharmacological effect of basil to mice (Mrcs mrrsarlrrs) sperm quality and its reproductive organ. This research were conducted at Animal Breeding and Genetic Laboratory, Faculty of Animal Science, Bogor Agricultural University, from May up to August 2005. Experiments were done for seven week feeding trials, a total of 30 weaning mice were allotted to three treatment levels. The treatments were done by giving dried basil at level 0; 2.5; and 5.0% from diet.Data were collected 50% from each treatment level (5 mice each). Observation variables were 1) measurements of reproductive organ such as width and length of scrotal; width, length, and weight of testis and penis; length of epididymis, and vasdeferens; and 2) sperm quality such as sperm concentration, viability, motility, abnormality, and mass movement. Data were analyzed by completely randomized designed one way pattern with 10 repetitions, and continued with Tukey Test. It was discovered that the treatments did not give significant effect both to sperm quality and reproductive organ measurement except to the scrotal and epididymis. It was found that scrotal length significantly increased (P<0.01) in 2.5% level as compared with 0% level, but there was no significant differences in 5.0% level as compared both with 0 and 2.5% level. Scrotal width increased (PCO.05) in 2.5% level as compared both with 0 and 5.0% level, but there was no significant increased in 5.0% level as compared with 0% level. Also found that epididymis length increased (P<O.OS) in 2.5% level as compared in 0% level, but there was no significant differences in 5.0% level as compared both with 0 and 2.5% level.

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.
