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: Pengaruh Pemberian Ekstrak Minyak Jintan Hitam (Nigella sativa) Terhadap Organ Limfoid Sekunder Mencit (Mus musculus)
Abstrak: Concerning to the people who were realized the importance of returning to a healthy lifestyle and back to nature was the reason of this research done using black seed (Nigella sativa). The purpose of this research was to study the effect of black seed oil extracts in secondary lymphoid organ of mice (Mus musculus). Twenty four of 4 weeks age mice were divided into 2 groups by gender. First group was male group and the other was female group. Both male and female groups were subdivided into 4 groups, each group consisted of three mice. Group I was control (received aquadest 0,1 ml), Group II (received 0,1 ml black seed oil Extracts), Group III (received 0,2 ml black seed oil extracts), and Group IV (received 0,3 ml combination of black seed oil Extracts and honey). This treatment were done for two months, the mice were then euthanized. The lymph node and spleen were collected as histopathological samples. Samples were processed routinely to prepare histopathology slide stained with Haematoxylin Eosin. The parameters observed were the number and width of lymphoid follicle on both spleen and lymph node. Quantitative data were analyzed with ANOVA test and followed by Duncan test. The observation results of that the mice given black seed oil extracts showed increased of lymphoid follicle wide of spleen and lymph node on group II, III, and IV which are significant (p<0,05) compare to 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.
