Abstract

The butterfly flowers (Clitoria ternatea L.) are used as natural dyes and herbal medicines because they contain metabolites, anthocyanins and antioxidants. The content of these metabolites is influenced by the phase of flower development. This study aims to determine the levels of anthocyanins, antioxidants and metabolites of butterfly pea flowers from different flowering phases. The Butterfly flower collection was taken from the village of Mulyaguna, Teluk Gelam, Ogan Komering Ilir, South Sumatra. The extraction was carried out with 70% ethanol solvent, and determination of the amount of anthocyanin content by spectrophotometry, antioxidant content by DPPH method, and metabolite compounds by GC-MS. Data on anthocyanin and antioxidant content were analyzed with averages and standard deviations, and GC-MS chromatograms were traced for compounds with reference to the PubChem, KEGG, ChEBI, PlantCyc, and Spectrabase websites, which then determined the dominant compound group. The results of the study on blooming butterfly pea flowers found that the antioxidant content was 6.58 ppm, higher than that of bud flowers, which were 2.55 ppm, and wither flowers, which were 1.74 ppm. The anthocyanin content of the blooming butterfly pea flower was 40.33 ppm, the withering flower was 4.36 ppm, and the bud flower was 3.60 ppm. The dominant metabolites were identified as fatty acids, organic acids, aromatics and flavanoids, followed by differences in antioxidant and anthocyanin content in the flowering phase of the butterfly pea flower

Abstract: This research aims to find out whether the Know Want Learned (KWL) strategy can improve students' interpretative reading comprehension in elementary schools. The method used is a quasi-experimental quantitative method with a Nonequivalent Control Group Design. The sample for this research consisted of 25 class IV students at SDI Tahfidz Preneur Pagipon. The average value of the control class was pretest 61.2 and posttest 73.4. The experimental class was pretest 59.6 and posttest 78.4. The normality results for the control class pretest were 0.147 < 0.173, the control class posttest 0.153 < 0.173 and the experimental class pretest 0.139 < 0.173, the experimental class posttest 0.099 < 0.173. The homogeneity test results for the control and experimental class pretest scores were F count 1.774 and F table 1.983, the post test scores for the control and experimental classes were F count 1.365 and F table 1.983.  The results of hypothesis testing obtained were Tcount 1.703 and Ttable 1.677 or tcount > ttable, namely Ho was accepted and Ha was rejected with the results of the hypothesis reading interpretative comprehension who received the Know Want Learned (KWL) strategy treatment being better than students who received the Know strategy treatment Want to Learn (KWL). Likewise, the N-Gain results obtained by the experimental class were 0.48 with medium criteria which shows that after implementing the Know Want Learned (KWL) strategy there was an increase in students' interpretive reading comprehension in elementary schools.Keywords: Know Want Learned (KWL) Strategy, Reading Comprehension Abstrak: Penelitian ini bertujuan untuk mengetahui apakah strategi Know Want Learned (KWL) dapat meningkatkan membaca pemahaman interpretatif peserta didik di sekolah dasar.

Abstract

The increasing number of pandemic cases has an impact on the education sector. This study aims to determine whether the learning outcomes of students who use Edmodo are better than students who use Google Classroom. The method in this research is an experimental method with a quasi-experimental design. This method is an experimental based quantitative method to show whether there is an effect on the independent variable (treatment) to the dependent variable (results) in a controlled situation. The results of this study indicate the difference in the average learning outcomes of 78 for the experimental class and 56,5 for the control class. This is evidenced by the value of the different test results (t) from the above calculation it is obtained that tcount 3,74 and ttabel 1,68, which means that H0 is rejected and Ha is accepted. This indicates that the learning outcomes of students in the experimental class are better than students in the control class.

Several factors contribute to the low interest in reading in Indonesia, namely the growing development of technology, making the current generation more busy with gadgets than reading books, this is not in line with the progress of learning media innovation. The purpose of this study was to determine (1) the process in developing Educational Game-Based Read & Play media to foster reading interest, (2) the feasibility of Educational Game-Based Read & Play media to foster reading interest, (3) students' responses to the implementation of Read & Play Educational Game-Based Play to foster interest in reading. The research method is Research and Development (R&D) using the 4D model by Thiagarajan which consists of 4 stages, namely define, design, develop, and disseminate. The results of research at SDN Kutabaru 1 in class 2 with a total of 31 students showed that Educational Game-Based Read & Play media was very feasible to foster students' interest in reading. This is proven by the validation results from two media experts with a percentage of 93.5% in the category "Very Eligible", two linguists with a percentage of 81% in the category "Very Eligible", two material experts with a percentage of 86% in the category "Very Eligible". The response of students' reading interest to Educational Game-Based Read & Play media in the trial of 31 respondents was 97% in the "Very Good" category.
