Abstract

The purpose of this study was to determine the effectiveness of the Team Games Tournament (TGT)- type cooperative learning model in improving students’ collaboration and conceptual understanding of biotechnology material in grade X high school. This study used a quasi-experimental design, with a total sample of 69 students, divided into 2 classes: 36 students in the experimental class and 33 in the control class. Collaboration skills data collection used peer assessment questionnaires, while conceptual understanding data collection used multiple-choice tests. The data analysis technique used was inferential statistical analysis, consisting of prerequisite tests (normality and homogeneity) and hypothesis tests (independent-samples t-tests, Mann-Whitney U tests, and Wilcoxon tests). The results of this study indicate that: (1) The use of the Team Games Tournament (TGT) learning model in biotechnology material does not have a significant effect on the collaboration skills of grade X students with an average value in the experimental class of 84.53, while in the control class it was 82.61, with a significance value of 0.521 0.05; (2) The use of the Team Games Tournament (TGT) type cooperative learning model on biotechnology material is effective in improving the conceptual understanding of class X students with an average posttest score in the experimental class of 80, while in the control class it was 72.12, with a significance value of 0.024 0.05. The TGT-type cooperative learning model can be recommended as an alternative learning strategy to improve conceptual understanding of biotechnology at the high school level, particularly by encouraging students’ cognitive engagement through structured competitive activities. However, to optimize the improvement of collaboration skills, modifications to the learning design are needed, such as emphasizing individuals’ roles in groups, strengthening process assessments, and integrating collaborative reflection.

The method used for this development was research and development (R&D) with the 4D (Define, Design, Develop and Disseminate) research model. The sampling method for the study was conducted random sampling. Method using one experiment class and one control class. This research in SMA Negeri 1 Ngemplak. Data Collection Techniques were using interviews, visionary, pre-test, and post-test. Ebook validation was carried out by material and media validators. The data analysis technique used a quasi-experimental non-equivalent control group design with the multivariate test by IBM SPSS 24. The ebook has validation and got 92,6% from the biology teacher, that is mean the ebook is valid and possible to use in biology learning. The Effect size shows 0.290 for critical thinking and 0.159 for cognitive learning outcomes, which means ebook has a high effect on both abilities

Abstract

This research aims to develop a PBL-based Respiratory App learning media on human respiratory system material, and to asses the feasibility, practicability, and effectiveness of the PBL-based Respiratory App learning media to improve critical thinking skills of class XI students at SMAN 6 Yogyakarta. This research used the ADDIE model developed by Dick and Carry. ANOVA test was used to analyze data of critical thinking skills. The results of the feasibility of learning media from material expert lecturers obtained an average score of 3.0 with a decent category. Media feasibility assessment conducted by media expert lecturers obtained an average score of 3.8 with a very feasible category and practicability assessment from biology subject teachers obtained an average score of 3.5 with a very practical category. The results of the small group trial obtained an average score of 3.3 with a practical category. Field trials using quasi-experiments showed sig 0. 00, and the experimental class’s critical thinking skills significantly different from the control class. The N-gain score showed the experimental class value is higher than the control class. Based on the research results, it will be concluded as follows: 1) PBL-based Respiratory App learning media was feasible and practicable for use in the learning process. 2) PBL-based Respiratory App learning media effectively improves students' critical thinking

Abstract

Hyperglycemia condition that leads to diabetes causes various complications. Various active compounds from plants have been studied for their antidiabetic abilities. One of them is the orchid plant. Besides being used as decoration, orchids contain several active compounds that have been proven to be used in medicine, including diabetes. This article discusses the antidiabetic mechanism of several active compounds obtained from orchids. Publication regarding orchid plant for diabetes were found in databases such as PubMed, Google Scholar, Wiley, Science Direct, Medline, Scopus, and Springer. Keywords used in this study were “orchid”, “diabetes”, “hyperglycemia”, “compound” and “herbal”. Out of the 447 collected articles (published in the period between 2011 and 2022), 416 were excluded due to non-relevant studies. There were 31 eligible studies included in this article. In conclusion, the antidiabetic mechanisms of the orchid extracts were as antioxidant, anti-inflammatory and anti-glycation agents, increasing insulin action, influencing lipid metabolism, and inhibiting α‑amylase and α‑glucosidase activity.

Abstract

Increasing students' interest in learning is a key factor in achieving effective and optimal educational outcomes. One approach that can enhance students' learning interest is through the use of electronic student worksheets, which encourages students to actively engage in the learning process. This study aims to evaluate the effectiveness of electronic student worksheet based on Problem Based Learning (PBL) to enhancing students' learning interests. This research uses a one-group pretest-posttest design involving 27 students from the XI MIPA class at SMAN 1 Jetis, selected through random sampling. IBM SPSS 25 was used to analyze the data using the Wilcoxon test and N-gain. Following the intervention, students' interest in learning increased significantly, according to the study's findings, with an average pretest score of 48.11 and a posttest score of 64.15. The results of the Wilcoxon test indicated a significant difference between the pretest and posttest scores, with a significant value of 0.000 (p < 0.05). In addition, the N-gain results show an average percentage increase of 56.46%, which falls into the quite effective category.

Abstract

Urinary tract infection (UTI) is a disease caused by both Gram-negative and Gram-positive bacteria. Red algae (Kappaphycus alvarezii) contain bioactive compounds derived from secondary metabolites with antibacterial properties. This study investigates the potential of Kappaphycus alvarezii methanol extract to inhibit the growth of Enterococcus faecalis ATCC 29212 and Pseudomonas aeruginosa ATCC 27853 using the microdilution broth method, determining Minimum Inhibitory Concentration (MIC) values ranging from a concentration of 500 µg/mL to 1.9531 µg/mL. To elucidate the inhibition mechanism, nucleic acid, protein, and Ca2+ ion leakage assay were performed via spectrophotometry at MIC 1, MIC 2, and MIC 3 concentrations. Morphological changes in the bacterial cell membrane were further examined using Scanning Electron Microscopy (SEM) at MIC 2. The results demonstrated that, the methanol extract of K. alvarezii exhibited significant antibacterial activity against Enterococcus faecalis bacteria with an MIC value of 1.9531 µg/mL, but showed no inhibitory effect on Pseudomonas aeruginosa. The extract inducted membrane leakage, as indicated by a higher leakage value compared to negative controls and commercial antibiotics. In addition, the methanol extract of K. alvarezii caused alterations in bacterial cells. These findings highlight the potential of Kappaphycus alvarezii methanol extract as a promising antibacterial agent.
