Antifertility Effect of the Ethanol Extract of Centella asiatica L. Urban Against the White Rat (Rattus norvegicus L.) in the Early Post-Implantation

Centella asiatica is commonly known as centella or pegagan is one of the biological
resources that have many benefits for mankind. Clinical and pharmacological study of Centella
asiatica has been widely proven by scientists of the world, but there are a few properties that
require further investigation in particular its effect on fertility. This research aims to know the
influence of the ethanol extract of pegagan (Centella asiatica) towards the birth rates or
fertility in the early post-implantation. On the research, white rat (Rattus norvegicus L.) is used
as animal tested. The method that used in this research was an experiment by using randomly
complete design. The tested animals were grouped into 4 treatment i.e. group I (control group),
group II (dose 175 mg/kg body weight), group III (a dose of 200 mg/kg body weight) and
Group IV (dose 225 mg/kg body weight). The tested animals were given the exraction of
Centella asiatica leaf orally with different doses for 15 days after post-implantation. The value
of post-implantation death percentage is calculated by counting the number of implantation,
either containing a live fetus, or dead fetus and embryo resorb. The results showed that
Centella asiatica gave the influ-ence on white white rat ferlitisation. On the grup IV treatment
with the dose of 225 mg/kg body weight showed the highest KPI val-ue i.e. 57.23%.

‘Da’wah Islamiyah’ Values of API TAUHID Novel by Habiburrahman El Shirazy: Sructural Genetic Study

This research aims to find the Islamic da’wah values in Api Tauhid novel by Habiburrahman El Shirazy using genetic structural study. This research is qualitative research using content analysis technique. The findings of the values observed in terms of da’wah bil hikmah method are 28 pieces, da’wah bil mauidzah alhasanah method are 48 pieces, and da’wah bil mujadalah alhusna method are only 9 pieces. Meanwhile, the values of Islamic da’wah in terms of the da’wah material are as follows. The Islamic da’wah values of aqidah material are 21 pieces. And Islamic da’wah values in terms of morality material are 22 pieces. Thus, the overall total of the values of Islamic Da’wah is 128 pieces. It can be concluded that the da’wah bil almauidzah alhasanah is more widely used in the Islamic da’wah method of Api Tauhid novel. And da’wah material that is more widely used in the Islamic da’wah of the novel is morality (morality for God and neighbor). From the above conclusion, it is understandable that the da’wah conducted by Habiburrahman in the Api Tauhid novel talks more about morals through bil mauidzah alhasanah (good word) method. The researcher found the correlations between the content of the novel with the author’s life. First, the characters of Hamza and Bilal who know the
biography of a remarkable scholar Bediuzzaman Said Nursi in very detail, so that in the story they are able to tell Bediuzzaman Said Nursi’s struggle coherently. Secondly, the depiction of the characters in the novel are very religious, especially the main character, Fahmi. Religious background is created no other than the madrasah he attended, after which he studied at boarding schools, and finally he enrolled to study religion in the
Middle Eastern country. Third, the story when Fahmi invited by his friend, Hamza (the Turk) to get around Turkey in memory of the history of the struggle of Bediuzzaman Said Nursi. Fourth, it is told in the novel about the Fahmi, Hamza and his friends’ trip in Turkey. They visited various places that become the traces of the history of Islam and the struggle of Bediuzzaman Said Nursi. Based on the correlation explained above, the author in his work cannot be separated from the circumstances of the surrounding community. In this case, the characteristics, ideological, political, economic, and social culture’s are influental on this Habiburrahman’s work. Social culture that is attached to a work can be viewed from several aspects, such as: social culture, language, religion, employment, customs, arts, and others. The implication of this research is the implementation or application in High School which is expected to have a positive impact on students after
studying the literature teaching topic. Api Tauhid novel may be one of the sources of teaching Indonesian subject for High School class XII in the second semester.

The Alpha-Amylase Inhibition Potential of Endophytic Fungi from Indonesian Bay Leaves (Eugenia polyantha WIGHT.)

Indonesian people use bay leaves as spices in local culinary and as traditional medicine, particularly to treat
diabetes. The problems with the mass production of antidiabetic drugs from bay leaves can be solved by
utilizing endophytic fungi as an alternative source for antidiabetic compounds. This study aimed to isolate
endophytic fungi from bay leaves and identify their antidiabetic activity through the in vitro inhibition of
alpha-amylase. The leaves were processed on potato dextrose agar media, and five isolates were grown in
an agar medium. The fermentation used a potato dextrose yeast medium that was left for five days on an
orbital shaker at room temperature. The crude was extracted using ethyl acetate solvent. In the in vitro
alpha-amylase inhibition test, the antidiabetic assay used the ethyl acetate extract of the endophytic fungi.
The inhibition percentage was calculated from the absorbance value read by a microplate reader. All isolates
inhibited alpha-amylase activity, but only three of them had high inhibition percentages (14.385%,
12.849%, and 39.246%). As a conclusion, the endophytic fungi isolated from bay leaves are potential as an
alternative source for the production of secondary metabolites to cure diabetes.

Formulation, Characteristic Evaluation, Stress Test and Effectiveness Study of Matrix Metalloproteinase-1 (MMP-1) Expression of Glutathione Loaded Alginate Microspheres and Gel

Background: The present study aimed to formulate and evaluate the stability, characteristics and effectiveness of glutathione-loaded alginate microspheres through increased lipophilicity using surfactant with a Hydrophylic-Lipophilic Balance (HLB) value equal to 7. The selection of glutathione as an antioxidant was based on its prominent role in maintaining intracellular redox balance. Alginate was used as the polymer, while calcium chloride constituted a cross-linking agent and Tween and Span were employed as surfactants.
Methods: The study applied an ionotropic gelation-aerosolization method. Microspheres were characterized by their morphology, size, drug loading, entrapment efficiency and yield. Stress testing utilized a forced degradation method, while an effectiveness study of glutathione incorporated a Matrix Metalloproteinase I (MMP-1) parameter on mouse skin. Glutathione-microspheres, to which had been added surfactants with a HLB value equal to 7, were compared to those without surfactants.
Results: Microspheres demonstrated both high yield and encapsulation efficiency. From the stability study conducted, it was evident that the glutathione-microspheres with additional surfactant were more stable than glutathione with surfactant, but without microspheres. Similarly, the glutathione-microspheres with additional surfactant were more stable than the glutathione without surfactant. The in vivo effectivity showed lipophilic glutathione microspheres were able to decrease MMP-1 expression in the dermis tissue of mice.
Conclusion: The results of freeze-dried glutathione-loaded alginate microspheres with surfactant with a HLB value equal to 7 can be utilized as potential glutathione delivery systems.

Partition Coefficient and Glutathione Penetration of Topical Antiaging: Preformulation Study

Glutathione (GSH) is a broad antioxidant of the thiol-tripeptide group, highly hydrophilic, which has limitation for topical preparations. A lipophilic surfactant is an alternative method to enhance the glutathione partition. The purpose of this study was to determine the apparent partition coefficient (APC log) of glutathione; glutathione with additional surfactant at different HLB value of HLB 4.3; 5.5; 7; 11 and selected HLB was studied for penetration. The study was conducted by dissolving glutathione in water plus various HLB surfactants. Determination method of partition coefficient was done by shake flash method. The penetration test was conducted using the parameter of decreasing Matrix Metalloproteinase-1 expression on the balb-c male skin. The results can be used as a reference for topical glutathione formulations as these results are preformulation study.

THE EFFECT OF SODIUM ALGINATE CONCENTRATION ON GREEN TEA LEAF (Camellia sinensis L.) EXTRACT GEL AS TIROSINASE INHIBITOR

Green tea leaf (Camellia sinensis L.) is a great plant containing polyphenol compounds
such as catechin and gallocatechin gallate that can be used as tyrosinase inhibitors. In
this study, the green tea leaf extract made into gel dosage form using sodium alginate as
a gelling agent. This research aimed to determine the effect of different sodium alginate
concentrations on the physical stability of gel extract green leaf and to know the effect of
gel formulation on tyrosinase inhibition. Gel made into 3 formulas with each
concentration of sodium alginate of 2; 2.5; 3%. The extraction of green tea leaves was
performed by reflux using 50% methanol solvent. The results showed that the three
formulas did not occur in phase separation, and had IC50 values of 34.80, 23.27, 20.69
μg/mL. The conclusion is gel dosage form with 3% sodium alginate gave the best
inhibition of tyrosinase with IC50 of 20.69 μg/mL.

Evaluation of analgesic and anti-inflammatory activities of ethanolic extract of Cordia sebestena L.

Trees and shrubs of the genus Cordia are widely distributed in the warmer regions, including Indonesia. The aim of this study
was to evaluate the analgesic and anti-inflammatory properties of the ethanolic extract of plant leaves in Wistar albino rats.
The analgesic activity was evaluated using the hot plate method and acetic acid-induced writhing, and the anti-inflammatory
activity was determined using carrageenan-induced paw oedema. The results showed that the Cordia sebestena ethanol extract
(100, 200 and 400 mg/kg) exhibited significant analgesic effects in a dose-dependent manner in the two pain models tested. The
extract also exhibited significant anti-inflammatory effects in the carrageenan-induced inflammation test. The data obtained
support the traditional folklore therapeutic claim about its analgesic and anti-inflammatory properties. Nonetheless, further
scientific investigation is required to establish its analgesic and anti-inflammatory properties in other experimental models and
clinical settings.
