Judul: Efektivitas Penyuntikan Pregnant Mare's Serum Gonadotropin Sebelum Perkawinan Pada Bobot Organ Anak Tilllis Putih Saat Lahir
Abstrak: An experiment was conducted at the Laboratory of Physiology, of Physiology and Pharmacology Department of The Faculty of Veterinary Medicine, Bogor Agricultural University from December 1999 until January 2001 to study the effect of superovulation with PMSG prior to mating on the organs weight of pups. Twenty mature rats Sprague Dawley strained were used in this experiment. 1he experimental rats were assigned into a randomized design with 4x2 factorial arrangement. The first factor was PMSG (0; 37.5; 75 and 150 IU/kg BW). The second factor lVas pups sex (male and female). Diestrus rats were injected with PMSG via intraperitoneal. Fourty eight hours later hCG was injected to increase ovulation, then the experimental rats were mated and maintained until parturition. The organ (the heart, lungs, liver, spleen, kidney, brain, ovary and testicle) of two hundred and twenty six pups bom were measured. The result showed that PMSG did not influence the body weight and organs weight except for the ovarium weight of female pups.

Judul: Efektivitas Penyuntikan Pregnant Mare's Serum Gonadotropin Sebelum Perkawinan Terhadap Pertumbuhan Prasapih Dan Bobot Sapih Anak Tikus Putih
Abstrak: Penelitian tentang pengaruh penyuntikan pregnant mare's serum gonadotropin (PMSG) sebelum perkawinan terhadap pertumbuhan bobot badan harian anak prasapih dan bobot badan sapih anak tikus usia lepas sapih telah dilakukan di Laboratorium Fisiologi, Bagian Fisiologi dan Farmakologi, Fakultas Kedokteran Hewan, Institut Pertanian Bogor dari bulan Desember 1999 hingga lanuari 200 l. Tikus putih betina dari galur Sprague Dawley yang digunakan sebanyak 20 ekor dan berumur 10 minggu atau yang telah dewasa kelarnin. Rancangan percobaan mengikuti pola rancangan acak lengkap dengan empat perlakuan penyuntikan PMSG (0; 37.5; 75 dan 150 IU/kg BB) dengan lima ulangan pada masing-masing perlakuan. Penyuntikan dilakukan secara intra peritoneal saat tikus mengalarni fase diestrus. Penyuntikan human chorionic gonadotropin untuk membantu terjadinya ovulasi dilakukan setelah empat puluh delapan jam kemudian. Selanjutnya induk tikus dikawinkan dan dipelihara sampai partus. Anak tikus yang dilahirkan sebanyak 218 ekor dipelihara hingga lepas sapih dan ditimbang bobot badannya setiap dua hari dan saat usia lepas sapih. Hasil penelitian menunjukkan bahwa PMSG dosis 37.5; 75 dan 150 IU/kg BB tidak mempengaruhi pertumbuhan bobot badan harian anak prasapih dan bobot badan sapih anak tikus usia lepas sapih.

Judul: Kekonsistenan Hamiltonian pada Gerak Gelombang Interfacial
Abstrak: The interfacial wave is an internal wave that occurs at boundary of two layers fluid. It appears because there is difference of mass density between the two layers. The objective of this thesis is to formulate the motion of internal wave with flat base and flat as well as free upper bound surface. The motion equation obtained is a Hamiltonian system. The Hamiltonian in this system is expressed by variable of wave deviation and horizontal component of potential velocity. Under assumption that interfacial wave moves only in one direction, it can be shown that the Hamiltonian depends on the solution of the wave motion equation. The coefficients of the equation depend on the physical characteristics of the two layers of fluid, i.e. thickness and mass density. The numerical results show that Hamiltonian in the system is constant. It is consistent with Hamiltonian characteristic, which does not depend on time.
