Abstract

Students' low STEM literacy level is a major challenge in 21st-century education, particularly in preparing students to face real-world problems. This study aims to examine the effectiveness of the STEM engineering design process (STEM-EDP) approach in enhancing students STEM literacy in the context of earthquake disaster mitigation. A quasi-experimental method was used with 50 eighth-grade students divided into an experimental group (28 students) and a control group (22 students). The experimental group applied the STEM-EDP approach, while the control group received conventional instruction. The results show that the STEM-EDP approach significantly improved students STEM literacy, with an average N-Gain of 0.33 (moderate category), compared to 0.23 (low category) in the control group. These findings indicate that the STEM-EDP approach enhances STEM literacy more effectively than conventional methods. This approach is relevant for addressing 21st-century challenges by integrating STEM literacy into meaningful learning experiences, particularly within the context of authentic, project-based education

Abstract

Students' low critical thinking on controversial environmental issues reflects weak skills in analyzing and concluding information, worsened by the absence of effective learning tools such as student worksheets (LKM) designed to foster critical thinking skills. The purpose of this article is to describe and test the extent to which the use of LKM can affect students' critical thinking skills (CTS) in understanding and responding to controversial environmental issues. By understanding the influence of LKM on CTS, it is hoped that more effective strategies can be found in integrating environmental education into the higher education curriculum. The type of research in this article is descriptive qualitative. Data collection techniques through observation and document analysis. The data analysis process begins by reading observation notes and worksheet documents repeatedly to identify aspects of CTS that are identified. These aspects are then organized based on categories that are relevant to the research objectives. Furthermore, comparing data from various sources (observations and documentation) to ensure consistency of findings and increase the validity of the research results. The results of the study indicate that the use of worksheets is effective in improving students' CTS on controversial environmental issues, as shown by an increase in the quality of discussions and arguments that are more structured and in-depth

Abstract

This study aimed to evaluate the efficacy of kelulut (H. itama) honey as an antiglaucoma agent in rats. Kelulut honey diluted to a concentration of 400 ppm using distilled water was prepared for chemical and biological analysis. Secondary metabolites in the extracts were identified by phytochemical methods and antioxidant activity was evaluated by DPPH method. In vivo test was conducted on R. novergicus rats that had been treated with intraocular pressure with 5 treatment groups and 5 repetitions for the antiglaucoma test. In addition, in silico studies were also conducted using apigenin, cathecin, luteolin, naringenin and taxifolin against Rho Kinase protein. The results showed that kelulut honey extract has been confirmed to contain alkaloid, flavonoid, and flavone compound classes. The extract was also confirmed to have antioxidant activity with an IC50 value of 6.2 ppm against 5.4 ppm ascorbic acid. The findings showed that kelulut honey has efficacy as antiglaucoma in rats. The secondary metabolites in this honey, especially alkaloids, flavonoids, and flavones, showed high antioxidant activity (50). At a dose of 40 ppm, kelulut honey was showed to reduce intraocular pressure (IOP) by 46.56% in the right eye and 55.15% in the left eye of rats. This effect is comparable to the use of 2% pilocarpine. In silico study showed that all tested compounds have good binding affinity to protein targets, with promising key interactions. Therefore, kelulut honey was potentially a natural candidate for the development of antiglaucoma therapeutics.

Abstract

Science literacy is a skill that students need to have to face the challenges of the 21st century. One aspect that can improve science literacy is the use of teaching materials. The purpose of the study was to analyze the opportunities and challenges of improving students' science literacy using teaching materials. The research method used was a systematic literature review with a preferred reporting items for systematic reviews and meta-analysis (PRISMA) flowchart. The results showed that opportunities to improve science literacy are done through various ways including the use of teaching materials, in-depth review of books, and the use of technology. However, learning that involves science activities is still few and more conceptual. In addition, the teaching materials used only contain subject matter and examples of problems and solutions, without encouraging students to find learning concepts. The conclusion obtained is that teaching materials that can be used to improve science literacy include comics, multimedia, books, e-modules, worksheets, and mobile-based learning media.

Abstract

Free radicals contribute to the onset of various degenerative diseases, highlighting the need for safe and effective antioxidants. Given the potential side effects associated with synthetic antioxidants, Sonneratia caseolaris is considered a promising natural alternative. This study aims to isolate secondary metabolites from the roots of S. caseolaris, evaluate their antioxidant activity, and analyze their molecular interactions. Extraction was conducted using a range of solvents, and antioxidant activity was assessed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The ethyl acetate fraction exhibited the highest antioxidant activity and was subsequently subjected to isolation procedures. From this fraction, a white crystalline compound with a melting point of 251253C was obtained. Spectroscopic analysis identified the compound as 3,4,5-trihydroxybenzoate, a type of phenolic compound. This compound exhibited very strong antioxidant activity, with an IC value of 6.63 g/mL, which is significantly lower than that of ascorbic acid (17.64 g/mL), indicating higher potency. Molecular docking analysis showed that 3,4,5-trihydroxybenzoate formed strong interactions with active residues of cytochrome c peroxidase, particularly Trp51 and Gly112, through hydrogen bonds and hydrophobic interactions. Additionally, molecular dynamics simulations revealed that the compound-enzyme complex exhibited greater structural stability than the control (ascorbic acid), as indicated by lower residue fluctuations in root mean square deviation (RMSD) and root mean square fluctuation (RMSF) analysis analyses. These findings support the potential of Sonneratia caseolaris as a natural source for the development of antioxidant compounds with strong biological activity and favorable molecular interaction profiles
