Abstract

Cocoa fruit is one of the fruits with local wisdom that can benefit Indonesia. But its used still limited to the fruit, while the peel of the cocoa fruit is only discarded so that it becomes a waste that will have an impact on the surrounding environment. We can minimize the amount of waste from the peel of the cocoa fruit is to make something useful that is a potential drug raw material. In this study a qualitative test was conducted to determine the secondary metabolite content of the cocoa plant. Flavonoid test results have positive results that indicate a change in color. The results of phenolic and tannin testing have positive results that indicate the formation of bluish black or green. Saponin test results have positive results that indicate the formation of foam. Triterpenoid test results did not show positive results. Based on the results of the study, cocoa peel waste has the potential to be used as an alternative to potentially medicinal raw materials.

Abstract

This research aims to determine toxicity activity test of methanol and ethyl acetate total from Batak leeks (Allium chinense G. Don). The method was using the Brine Shrimph Letality Test (BSLT). Methanol and ethyl acetate extracts of Batak leeks were diluted using salt solution with concentration variations (10, 100, 1000)ppm. Salt solution also was used as negative blank. The research model was in Vitro experimental research model. The results showed that methanol extract of Batak leeks on 6576578 mg / L which was non-toxic and LC50 on ethyl acetate extract of Batak leeks was 16.59 mg / L which was a strong toxic compound.

Abstract

The identification of heavy metals Hg, Pb and Cd in the Batang Kuantan River, Kuantan Singingi Regency has been carried out successfully. Heavy metals are measured not only from their heavy metal content such as Hg, Pb and Cd but also from the pH level of the river flow itself. The research location is at the Batang Kuantan River, which is measured from 3 points. Changes in Data Observed / Measured are the quality levels of heavy metals in the waters. The research model used includes field research using survey and laboratory methods. The research design was analyzed using the Atomic Absorption Spectometer (AAS). The water sample was given HNO3 until it was acidic and filtered so that there was no sedimentation, then analyzed by AAS. Heavy metal analysis result data technique is compared with quality standard of government regulation no 82 of 2001 regarding water pollution control and water quality management. Pb did not have a problem because the levels were not found. Whereas for Cu and Cd in the category of concentration threshold for reasonableness, which ranged from 0.158-0.1598 ppm and 0.0233-0.2769 ppm.

Abstract

This research is a quantitative study that aims to analyze the effect of ethical judgment on student behavior at the Kuantan Singingi Islamic University (UNIKS). The population used was students of the Tarbiyah and Teaching Faculty (FTK) with the sampling technique. Random sampling used SPSS. Data collection techniques use secondary data sources and pimer, for independent variables using secondary data sources by directly requesting the FTK UNIKS archive center, while the dependent variable uses primary data sources obtained directly from the original source through the Behavior scale. The test statistic needed to test the hypothesis is the correlation coefficient between the test score as a predictor and the score of a criterion. The interpretation of the analysis results in predictive studies is based on the betha index (β) or the b score in the regression model obtained. From the results of the study it was concluded that there was an effect of ethical judgment on the behavior of FTK UNIKS students with sig = 0.00 and F = 50.524, Y = 31.5 + 0.645X

Abstract

This research aimed at developing chemistry education game of role playing game (RPG) based on the reaction rate material and to know product quality based on assessment of media, material experts and chemistry teacher subject. This research used the research and development method which refers to development models from Borg and Gall. The conclusion of this research was the chemistry education game of role playing game (RPG) on reaction rate based that was developed fulfills the criteria both of as a media learning chemistry independence. The media expert gave good scores (75.00%), the material expert gave good scores (80.00%), the teachers gave very good scores (92.00%). In the first filed try out, the students gave very good responses (92.10%). The qualitative assessment was suggestions from validators, teachers and students who said that chemistry education game of role playing game (RPG) based on the material of the factors influencing reaction rate have been said good.
