Indonesian people consider the Rubik plant (Calotropis gigantean) is only a wild plants that have no benefits. It is often felled and thrown away. This study was aimed to provide the information the utilized these crops. This research was conducted to determine the ability and characteristics of Rubik stems (Calotropis gigantean) as an addictive substance plasticizer filler, where the rubrik plant was taken at the seaside area of Banda Aceh. Preparation of plasticizers from the filler of this rubric stem was used as an antiseptic and biodegradable plasticizer. The results of FT-IR spectra measurements of the filler plastics of this rubrik plant have a distinct tannin functional group absorption, at 923.850 cm-1 strong buckling numbers were indicated the presence of a potent buckling C-H group due to the presence of the aromatic groups in the tannin compound. For the SEM test, the plasticizer has a porous surface morphology of the outermost layer, this indicates the density of particles smaller than the plasticizer 2 grams of water compared to plasticizer 1 gram of water. The test of biodegradable and Aspergillus Niger fungi on time variations about 10 days were resulted in significant degradation. The rate of degradation with soil was greater than the Aspergillus Niger. Toxicity was used of Escherichia coli bacteria in medium of nutrient agar at 37Â°C with 48 hours incubation where in plasticizer has antiseptic to Escherichia coli.

The observations result of the students of SMA Negeri 16 Banda Aceh, showing that the student were less motivated in learning process, they prefer to play and engrossed by their own activities, there were only several students whose really enthusiastic about the material being studied. In order of learning in the classroom went well, so that needs to be innovated the learning activities by using. One of the innovations was used, namely the instructional media, while the learning media that used was the dominoes card and the crossword puzzles. This study aimed to see the effectiveness of learning media on student learning outcomes in learning chemistry by using Dominoes card and crossword puzzle media. This research was the experimental, the research of this research was the student of XI-1 class student experiment class I (dominoes card media) and class XI-2 as experiment class II (crossword puzzle), with total sample was about 37 students. The sample selection based on Purpossive Sampling technique. The instruments used in the form of written tests consist of 20 multiple choice questions with cognitive competence level C1 (knowledge), C2 (understanding), and C3 (application), group worksheet (LKK) in the form of card media and a crossword puzzle, and implementation plan learning (RPP). The data collection techniques were by pretest and posttest, and then analyzed were by using the normality test, homogeneity test, and T test on hypothesis test with 19-version version of the Statistical Program for Social Science (SPSS) program. The results showed that there was no significant difference to the learning outcomes of students who were taught using domino card media and TTS media. It can be concluded that the domino card media and TTS media are very effective in improving the learning outcomes of the students of SMA Negeri 16 Banda Aceh.

General chemistry is a subject that being studied in almost every science course. The subject is closely related to the environment, so it will be very easy to learn when involve examples in everyday life. The Contextual Teaching and Learning (CTL) approach is an approach that links the learning materials with the real-world environment. This research was conducted by using a CTL approach in a general chemistry subject which is one of the compulsory subjects in Biology Education Program of Tarbiyah Faculty UIN Ar-Raniry. The aim of this study was to determine the increase of student learning activities after using the CTL approach to general chemistry lecturing activities. The design of this study used action classroom research. This study was conducted to the first semester students. The student amount was 31 students. The instrument used was an observation sheet of learning activity. The results was obtained that the activities of the student during the learning process in the first cycle reached 70% and increased to 90% in cycle II. This proves that the application of CTL approach can increase the learning studentâ€™s activity of Biology Education Studies in general chemistry courses.

Tea is one of kind drink that most be preferred and consumed the tea community around the world, even most common of the community utilized tea as a healthy drink because it contains antioxidants. Antioxidants can protect cells from damage that caused by the unstable molecules. The determination of tea temperature and optimum time were aimed to know how the influence of the caffeine content of antioxidants, tannin and chatecine. In a flood expected to contain low caffeine levels with high polyphenols.The method in this research was an extraction method that analyzed by using UV-Vis a spectrophotometer. The results showed that the lowest caffeine level was at a temperature 70Â°C for 15 minutes of 0.51 %, the highest levels of tannin was at the brewing temperature 70Â°C for 5 minutes of 4.783 %, the highest cetacean levels were at the brewing temperature 85Â°C for 5 minutes of 1.14 %. So that, the optimum condition was obtained at the brewing temperature70Â°C for 5 minutes, which have antioxidant activity about 56.75%.

In the learning process, most students have difficulties to understand the chemistry subject that delivered by the teacher. One thing that caused the difficulties of student learning was the minimum used of an appropriate learning model by the the teacher. This study was conducted to know the influence of Two Stay Two Stray learning model towards the improving of student learning result of Oxidation and Reduction Reaction Material, the student activity, and student response towards the study model of Two Stay Two Stray in SMA Bina Bangsa. The sample in this research was the students in class X of SMA Bina Bangsa. This research used the quantitative approach with a design research of Pre-Eksperimen. Data collection was done by multiple choice test, observation and student response questionnaire. The result showed that there was an increasing in student learning that taught by using learning model of Two Stay Two Stray at the test of normality with a significant level X2 count < X2 table or 1.467 < 11,1 states that the test has a normal distribution, whereas the t test with significance level of Tcount > Ttable or 8.251 > 2.13 that states there was an influence towards the students study research by using the Two Stay Two Stray model, while by n-Gain test the average students reaches the high criteria. The observation result of student activity has increased from 79.14% at the 1st meeting to become 88.33% at the 2nd meeting, the students also have a positive response towards the application of Two Stay Two Stray model study on Oxidation and Reduction Reaction material, with the student response percentage of â€œYesâ€ was 84% which means the students were interested with the Two Stay Two Stray model study.
