Science and religion are closely related because they come from one source, namely God Almighty. Therefore, the concept of the integration of science and religion must be implemented in the form of integrating religious characters in the science learning process. This study aims to identify and inventory the learning methods used to integrate religious character values in chemistry learning. This research is conducted by reviewing the literature, both in books, journal articles and popular scientific writings, about methods of integrating religious character values in chemistry learning. The main data sources are from journal articles that discuss the integration of religious characters in chemistry learning. The journal articles that became the main data source were ten articles obtained from the Google Scholar website using the keyword "integration of religious characters in chemistry learning". The research data were analyzed descriptively and qualitatively. A critical study was also carried out on the literature to obtain the correct conclusion. According to the teacher's creativity, the study results concluded that religious character values can be integrated in chemistry learning in various ways/methods. However, in their article, the researchers did not clearly and unequivocally mention the name of the learning method used to integrate religious characters in chemistry learning. Based on this conclusion, it is recommended that other research is needed to develop a learning model that integrates religious character values in chemistry learning.

Scientific attitude is very important for each individual student, especially in the learning process. The purpose of this study was to determine the profile of students' scientific attitudes by using an electronic science textbook based on local wisdom of Madura salt making. The research was conducted at SMP Negeri 2 Pademawu. This study uses a descriptive method with a quantitative approach. The population in this study was all class VII SMP Negeri 2 Pademawu. Samples were taken using a simple random sampling technique. Data was collected using an observation sheet for students' scientific attitudes consisting of 3 aspects, 9 indicators, and 10 statements and using interview techniques to add information about science learning. research results are included in the category of quite good. Therefore, these results still need to be improved so that they become very good by using models, methods, strategies, and textbooks that can improve students' scientific attitudes, one of the textbooks that can be used is electronic textbooks based on local wisdom.

BALANOCARPOL AND AMPELOPSIN H, TWO OLIGORESVERATROLS FROM STEM BARK OF Hopea odorata (DIPTEROCARPACEAE) Sri Atun; Nurfina Aznam; Retno Arianingrum; Masatake Niwa
Indonesian Journal of Chemistry Vol 6, No 3 (2006)
Publisher : Universitas Gadjah Mada

Two oligoresveratrol, namely balanocarpol (2) and ampelopsin H (3) had been isolated from the steam bark of Hopea odorata (Dipterocarpaceae). The structures of these compounds were elucidated based on physical and spectroscopic data (MS, 1H and 13C NMR 1D and 2D). The activity of these compounds was evaluated against the 2-deoxyribose degradation induced by the hydroxyl radical generated via a Fenton-type reaction. The result showed that activity each compounds as radical hydroxyl scavenger of balanocarpol, and ampelopsin H with an IC50 1802.3 and 4840.0 μg/mL, respectively. Each compound showed low activity. Vitamin C (IC50 83.9 μg/mL) and butylated hydroxyl toluene (1328.0 μg/mL) were used as positif controls. These results suggest that oligoresveratrols from stem bark of H. odorata may be useful as potential sources of natural antioxidants.

This study aims to determine the practice of argumentation to increase the knowledge and competence of acid-base material for prospective chemistry teacher students. This study uses a quantitative approach with a quasi-experimental method. The design of this research is the pretest posttest group. The sample in this study were 54 students of chemistry education at UIN Sunan Kalijaga Yogyakarta who were taking basic chemistry courses. Meanwhile, the knowledge instrument is in the form of a multiple-choice test, while the competency instrument is a test in the form of a description. The data analysis technique in this study was carried out statistically inferential (analysis of independent sample t-test). The results of the study show thaththere is a significant difference between the pretest and posttest values in the knowledge domain with t value is -5.508 and probability value paired t test is 0.00 (p value < 0.05). In addition, the mean is -4.167 (negative value) indicates that there is a tendency to increase knowledge significantly. There is also a significant difference between the pretest and posttest values of the competency domain with t value is -8.686 and probability value paired t test is 0.00 (p value < 0.05). In addition, the mean is -3,796 (negative value) indicates that there is a tendency to significantly increase the value of the competency dimension.

The purpose of this study was to determine differences in self-efficacy and problem-solving abilities of students in problem-based learning and scientific approach learning. This study uses a quasi-experimental research design with a pretest-posttest group research design. The sample used in this study consisted of two classes, namely class XI Mathematics and Natural Sciences 4 as the experimental class and class XI Mathematics and Natural Sciences 2 as the control class. A total of 70 class XI students were randomly selected as the research sample using random sampling technique. The instrument used was a test in the form of a description of the ability to solve problems and a non-test, namely a self-efficacy questionnaire. The analysis technique in this study used the Manova test and the Paired Sample T-Test. The results of this study indicate that there are significant differences in the self-efficacy and problem-solving abilities of students who take problem-based learning with students who take scientific approach learning. The contribution given by the problem-based learning model to self-efficacy and the ability to solve problems simultaneously is 71.5%, students' self-efficacy is 61.8%, and problem-solving skills is 43.3%.

This study aims to formulate and evaluate the anti-aging tamarind leaf (Tamarindus Indica L.) extract cream due to the increasing demand for the anti-aging product day by day. In this study, tamarind leaf extract was tested to find out its phytochemicals, antioxidant activity using a 1,1-diphenyl-2-picrylhydrazyl method, and anti-aging activity using a UV spectrophotometer. Anti-aging cream was formulated based on the antioxidant and anti-aging potential of tamarind leaf extract and its evaluation. The cream was formulated with tamarind leaf extract, carboxymethylcellulose, and base cream with different emulsion types (water in oil and oil in water). This study revealed that tamarind leaf extract contains alkaloid, flavonoid, saponin, phenol, and tannin. Tamarind leaf extract also has an antioxidant and an anti-aging activity. The cream evaluation showed that cream with extract concentration at 80 ppm emulsion types W/O and O/W placed in outdoor and indoors were to be stable during 4 weeks of stability studies. The creams still have antioxidant activity, do not experience a significant change in their physical appearance at organoleptic test, homogeny, pH range at 4.5-8, spreadability range at 5-7 cm in weight 0-50 gram, and are not separated during centrifugation test.
