Abstrak: Fennels are plant that contains phytoestrogen with effect like estrogen endogenous. This study aimed to know about administration of sweet fennels to observe reproductive performance such as an estrous cycle, weight of ovaries and uterine, and uterine vascularitation from 1 year old white female rats. This research used 25 female rats that were divided in 5 groups. KN is negative control given 1 ml/100 gBW destilated water. KP is positive control given etinil estradiol 0.045 mg/200 gBW. Treatment doses D1, D2, and D3 given infusion of 36.5 mg, 73 mg and 146 mg every 100 gBW fennel respectively. Treatment of destilated water, etinil estradiol and fennels infusion were done for 17 days with the oral route, at the same time with vaginal swab. Vaginal swab were taken 2 times a day with a period of 12 hours, to study the length of estroes cycle and its phase. After given treatment, the rats were necropsied to observe uterine vascularitation and weight of the ovaries and uterine. The changes of vaginal epithelium were examined to determine estrous cycle phase using a microscope. It was concluded that fennel fruit infussion at dose D1 can increased length of proestrus (P<0.05) and it can increased length of estrous phase (P>0.05). There were increasement of the ovaries and uterine weight from rats group KP, D1, and D2 (P>0.05), and D3 (P<0.05), however all groups did not show increasement of uterine vascularitation.

Abstrak: Fennel fruit are natural phytoestrogen compounds derived from plants and have an effect similar as natural estrogen. This study aims to describe the estrous cycle in productive female rats Sprague dawley given infusion of fennel.This research used 25 female rats that were divided in 5 goups. KN is negative control given 1 ml/100 gBB distilled water. KP is positive control given (etinil estradiol) 0.045 mg/100 gBB. Treatment 1, 2, and 3 (P1, P2, P3) given infusion of fennel with three different doses of 36.5 mg, 73 mg and 146 mg respectively for 100 gBB. Administration of distilled water, etinil estradiol and fennel were done for 20 days with the oral route, at the same time vaginal swab were taken to reveal the estrous cycle in rats in the morning and evening with a period of 12 hours. The changes of vaginal epithelium were examined to determine estrous cycle phase using a microscope. It was concluded that fennel fruit infussion doses 36.5 mg/100 gBB, 73 mg/100 gBB, 146 mg/100 gBB extend duration of estrous and metestrus phase but it become shorter the duration of proestrus and diestrus phase.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
