Judul: Efektifitas Pemberian Infusa Buah Adas (Foeniculum vulgare Mill.) terhadap Peningkatan Kadar Kalsium dan Fosfor Darah Tikus Putih (Rattus norvegicus) Ovariektomi.
Abstrak: Aging is common problem that usual accomplished by every people especially woman. Aging is one of occured when there is a decreasing of estrogen and calcium levels in the body. Adas plants contain the substance similiar to the active estrogen and potential for anti aging. This research was objected to see the effect of adas fruit infusion for enhancing of calcium and phosphor level in the ovariectomy rat’s blood. Twenty five rats were ovariectomized and acclimatizated for 45 days. The rats were divided into five groups with each groups consisted from five rats. First group was Negative Control (KN) with aquadest of 0.5 mg/100 g bb. Second group was positive Control (KP) with etinil estradiol of 0.25 mg/100 g bb. Third groups was Dose One Group (D1) with adas infusion of 73 mg/100 g bb. Fourth group was Dose Three Group (D) with adas infusion 146 mg/100 g bb. Fifth group was Dose Three Group (D3) with adas infusion 292 mg/100 g bb. The treatment was held for fifteen days and in the day sixteen, blood sample was taken. Adas fruit infusion test showed the increasing level of calcium and phosphor on D1, D2, and D3. The result showed that the most effective dose to increase calcium and phosphor level was at D3 with 13.51 mg/dl and 6.56 mg/dl

Judul: Pengaruh Pemberian Infusa Biji Adas (Foeniculum vulgare Mill.) Terhadap Perkembangan Folikel Ovarium Tikus Putih (Rattus norvegicus) Produktif dan Premenopause
Abstrak: Biji adas (Foeniculum vulgare Mill.) diketahui mengandung fitoesrogen, yang mempunyai efek kerja seperti hormon estrogen. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian infusa adas (Foeniculum vulgare Mill.) pada berbagai dosis terhadap perkembangan folikel ovarium tikus putih (Rattus norvegicus) produktif dan premenopause. Sebanyak 50 puluh ekor tikus yang terdiri atas 25 ekor tikus produktif dan 25 ekor tikus premenopause, masing- masing dibagi menjadi 5 kelompok yaitu kelompok kontrol negatif (KN) yang diberi aquades 1 ml, kelompok kontrol positif (KP) yang diberi etinil estradiol 9x10 mg/200 g BB, kelompok dosis I (D1) yang diberi infusa adas dengan dosis 36.5 mg/100 g BB, kelompok dosis 2 (D2) yang diberi infusa adas dengan dosis 73 mg100 g BB, dan kelompok dosis 3 (D3) yang diberi infusa adas dengan dosis 146 mg/100 g BB. Pemberian infusa adas dilakukan dengan cara pencekokan selama 16 hari. Hasil penelitian menunjukkan bahwa pemberian infusa adas dosis 36.5 mg/100 g BB, 73 mg/100 g BB, dan 146 mg/100 g BB selama 16 hari tidak berpengaruh terhadap tingkat perkembangan folikel ovarium tikus putih (Rattus norvegicus).

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.
