BACKGROUND: Corncob is one of crude drug which containing phenolic compounds that can be used as an active ingredient for sunscreen preparations. In this study, extracts of dried corn cob made into a gel formulation using SRC (Semi Refined Carrageenan) and glucomannan as a gelling agent. AIM: This study aims to determine the optimal concentration of SRC (Semi Refined Carrageenan) and glucomannan to the physical stability of the gel. METHODS: Gel made into four formulas with a ratio of 1: 4 and the concentration of each formula was 1%, 1.5%, 2%, 2.5%. Each formula was evaluated for 6 weeks of storage that includes organoleptic test, homogeneity, pH, viscosity, dispersive power, freeze-thaw test and centrifugation. RESULTS: The results showed the fourth formula did not change the organoleptic test and homogeneity test. In the test separation of the freeze-thaw method, the fourth formula was stable, while in the centrifugation test formula 1 and 2 was been separation. pH and viscosity results obtained from statistics with a two-way ANOVA showed significant differences in each formula. CONCLUSION: From the results of this study concluded that the formula 3 with a concentration of 2% was the optimal concentration as a gelling agent.

Citric acid is one of acid source that can increase dissolving time of effervescent tablet. This study aims at determining the optimal concentration of citric acid as acid source on dissolving time of effervescent tablet. Pericarp mangosteen (Garcinia mangostana L) dry extracts macerated with water, and powder made by spray drying process. Dry powder obtained was made into 5 formulas effervescent tablets used different concentrations of citric acid, i.e. 20.0, 22.5, 25.0, 27.5, and 30.0%. The tablets were evaluated included organoleptic evaluation, weight uniformity, size uniformity, hardness, friability, and dissolving times. The data in this research were physical properties of granule and tablets. For physical granule properties, i.e. flow time was fulfilling criteria, its flow time under 10 seconds for 100 g of granule. And also for angle of repose it was fulfill the criteria, it value was 25- o 45 . The tablet data of dissolve time fulfilling criteria its value was under 1-5 minutes all. For pH value all the formula were safe to be consumed, the average value was 4.347. By one-way ANOVA test dissolving time data there were differences each other. It could be concluded that the optimum concentration of citric acid as an acid source on dissolving time of the pericarp mangosteen (Garcinia mangostana L.) dry extract effervescent tablets was formula 4 with citric acid concentration of 27.5%.

Papaya seed in previous research is known has an effect of anthelmintic on Ascardia galli, but the effect of papaya seed just by traditional method i.e. boiling in water. To get the effective extraction methods, it still needs to be done many kinds of extraction methods of papaya seed, to know which one is the best. Methods of extraction in this research were maceration, soxhletation, and ultrasonic digestion. We used two kinds of papaya seed: wet and dry, using solvent: water, 70% ethanol, and n-hexane. Data of anthelmintic activity were percentage of worm death, LD50, and relative potential to pyrantel pamoate as positive control. The result showed that the best extraction method of papaya seed which had highest in vitro effect on Ascardia galli worm was maceration method with 70% ethanol as solvent of wet papaja seed. It killed 60% of worm with LD50 9.36 mg and its relative potential is 0.66 times pyrantel pamoate.

This research analyses the historical development of the Tarbiyah movement in Indonesia. Specifically, it analyses on how and to what extent the da’wa of the Tarbiyah movement has been transformed due its changing of religious, social and political dynamics of Indonesia since 1970s until now. Based on this written document-based research, I argue that the gradual transition of the Tarbiyah movement from a politically repressed network of religious purists in the 1970-80s into a fully-fledged dakwah political party (the Prosperous Justice Party /PKS) was the outcome of new ‘political opportunities’ which emerged during a period of demo­cratisation. The political situation during the time of the Tarbiyah movement’s emergence in the early 1980s saw state repression of Islamic movements and this constraint on political opportunity structures was one of the main factors causing the Liqo to be informally organised. Only in the post-New Order period (begun in 1998) did the movement start to generate its formal organizational structure in the shape of a political party named the PK(S). The move towards formality aimed to take advantage of the ‘political opportunity’ provided by a more democratic government, while the less formal and the informal aspects of their organisation supports the party in recruiting new members and mobilizing its sympathisers.

Tobacco has lots of active compounds that can be used as raw material for making natural insecticides. Tenebrio molitor and Zophobas morio are examples of agricultural pests. The purpose of this study was to determine LC50 values of tobacco extract on Tenebrio molitor and Zophobas morio. Previous research showed that tobacco extract had neurotoxin activity and nicotine was the highest content contained in the tobacco leaves. Tobacco extract was obtained by the Extended Heat Reflux Extraction method with ethanol solvent. LC50 values of tobacco extract for Tenebrio molitor and Zophobas morio were 21.1 mg/ml and 71.1 mg/ml, respectively.
