Judul: The Acute Toxicity Test of Moringa Seeds (Moringan oleifera L.) Infusion in  Mice (Mus musculus)
Abstrak: Potensi biji kelor sebagai bahan obat herbal telah banyak diketahui, namun informasi spesifik mengenai tingkat toksisitas dan keamanan dari biji kelor masih sangat terbatas. Penelitian ini bertujuan untuk menganalisis tingkat keamanan infusa biji kelor pada mencit menggunakan metode penentuan nilai lethal dose 50 (LD50), serta memberikan informasi tentang tingkat keamanan infusa biji kelor untuk perkembangannya sebagai bahan obat herbal. Sebanyak 20 ekor mencit betina dibagi menjadi empat kelompok dan lima ulangan. Mencit percobaan yang tidak diberi infusa biji kelor dikelompokkan sebagai kontrol, sedangkan yang diberi infusa biji kelor dosis 5, 10, dan 15 g/kg BB sebagai perlakuan. Pemberian infusa biji kelor dilakukan satu kali pada awal penelitian secara oral kemudian mencit diamati gejala klinis, mortalitas, dan bobot badannya. Pada akhir penelitian, mencit percobaan dikorbankan untuk dievaluasi parameter patologi anatomi. Hasil penelitian menunjukkan bahwa pemberian infusa biji kelor mendukung pertumbuhan bobot badan mencit secara normal, tanpa menyebabkan kemunculan gejala klinis patologis atau bahkan kematian. Simpulan penelitian ini ialah infusa biji kelor termasuk bahan yang praktis tidak toksik serta aman dan berpotensi untuk dijadikan obat herbal bagi masyarakat, The potential of moringa seeds as herbal medicinal ingredients has been widely known, but specific information regarding the level of toxicity and safety of moringa seeds is still very limited. This study aims to analyze the safety level of moringa seed infusion in mice using the lethal dose 50 (LD50) assessment method, as well as to provide information about the safety level of Moringa seed infusion for its development as a herbal medicine. A total of 20 female mice were divided into four groups with each contain 5 mice. Experimental mice that were not given moringa seed infusion as a control, while those given moringa seed infusion at doses of 5, 10, and 15 g/kg BW were the treatment. Moringa seed infusion was administered once at the beginning of the study orally and then clinical symptoms, mortality, and body weight were observed. At the end of the study, experimental mice were sacrificed for pathological views. The results showed that giving moringa seed infusion to mice did not cause death or specific clinical symptoms and normal growth. It was concluded that the infusion of moringa seeds including practically non-toxic ingredients.

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.
