Judul: The Effect of Extract Black Cummin (Nigella sativa) Oil Commercial Product on The Female Reproduction Organ of Mice (Mus musculus).
Abstrak: Jintan hitam (Nigella sativa) secara tradisional digunakan sebagai obat herbal yang sedang popular. Tujuan penelitian kali ini adalah untuk mengetahui efek jintan hitam terhadap histopatologi organ reproduksi betina mencit. Mencit betina umur empat minggu sebanyak 36 ekor dibagi menjadi empat kelompok, yaitu kelompok I diberikan aquades 0,1 ml, kelompok II diberikan 0,1 ml ekstrak minyak jintan hitam, kelompok III diberikan 0,2 ml ekstrak minyak jintan hitam, dan kelompok IV diberikan kombinasi ekstrak minyak jintan hitam dengan madu sebanyak 0,3 ml. Mencit diberikan perlakuan satu kali sehari selama dua bulan. Setelah dua bulan perlakuan, dilakukan nekropsi untuk mendapatkan ovarium dan uterus. Selanjutnya organ diproses untuk histopatologi dengan pewarnaan Hematoksilin-Eosin dan Periodic Acid Schiff. Paramater yang diamati terdiri dari luas ovarium dan folikel tersier; jumlah folikel ovarium, kelenjar uterus, dan sel Goblet; dan regenerasi epitel permukaan uterus. Hasil yang didapatkan menunjukkan bahwa jintan hitam meningkatkan kinerja ovarium dan perbaikan homeostasis uterus. Kesimpulan dari penelitian ini yaitu jintan hitam memberikan efek terhadap sistem reproduksi betina mencit.

Judul: Pengaruh Pemberian Ekstrak Minyak Jintan Hitam (Nigella sativa) terhadap Gambaran Histopatologi Organ Testis Mencit (Mus musculus)
Abstrak: This study was aimed to get information about Habbatussauda or blackseed (N. sativa) suplementation effect on mice testicle. Thirty six mices of 4 weeks were divided into four group, each group consists of nine mices. Group I was negative control (received 0.1 ml aquadest), group II (received 0.1 ml Habbatussauda oil), group III (received 0.2 ml Habbatussauda oil), and group IV (received 0.3 ml combination of Habbatussauda oil and honey). This treatment were done for two month, the mice were euthanized and then necropsied followed by testis collection as organ sample. Sample was processed to prepare histopathology slides with Hematoxilin-Eosin stain. The parameters observed include to count on and differenciate of the spermatogenic cells, Sertoli cell, and Leydig cell using software Image J® for Microsoft® Windows®. Qualitative data’s were analyzed with software SPSS® 16.0 for Microsoft® Windows® ANOVA test and followed by Duncan test. The result showed that Habbatussauda caused increasing of spermatogenic cells, Sertoli cell, and Leydig cell on group II, III, and IV which were significant (p<0.05) with the control group.

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.
