Abstract

Kersen leaves (Muntingia calabura L.) have long been utilized as a traditional medicinal plant used for headaches, antiseptics, antioxidants, antimicrobials, anti-inflammatories, anti-diabetics, and anti-tumors. This study aims to determine the antibacterial activity and the concentration at which kersen leaf extract can inhibit the growth of Multi Drug Resistant (MDR) Escherichia coli bacteria. The type of research conducted is a laboratory-scale experimental study. The kersen leaves were extracted using the maceration method with a 70% ethanol solvent. The antibacterial activity was tested using the agar diffusion method with sensitive and MDR Escherichia coli bacteria at varying concentrations of 1.25%, 2.5%, 5%, and 10%, conducted in three replicates and incubated for 24 hours. Subsequently, the inhibition zones were measured and the data were statistically processed. Based on the research results, at a concentration of 1.25%, an inhibition zone of 7.86 mm was obtained, at 2.5% concentration 9.65 mm, at 5% and 10% concentrations 11.93 mm and 13.98 mm on sensitive Escherichia coli bacteria, while on MDR Escherichia coli bacteria at a concentration of 1.25%, an inhibition zone of 6.51 mm was obtained, at 2.5% concentration 6.61 mm, at 5% and 10% concentrations 6.68 mm and 6.98 mm. These findings suggest that kersen leaf extract possesses moderate antibacterial activity against both sensitive and MDR E. coli, particularly at higher concentrations.

Abstract

Critical thinking plays a vital role in the learning process, as it supports knowledge development and involves evaluating topics, content, and challenges. This research sought to assess the impact of Reading, Questioning, Answering (RQA)-Integrated Concept Maps (RQA-Integrated CM) on improving students' critical thinking abilities. Using a quasi-experimental with a purpose sampling pretest-posttest one group design, 30 biology students from Patompo University in Makassar, South Sulawesi, Indonesia were sampled for the study. The data were collected through essay tests focused on Human Anatomy and Physiology, designed around critical thinking criteria such as basic clarification, bases for a decision, inference, advanced clarification, supposition and integration, strategies and tactics. The tests consisted of 12 valid and reliable questions. The data were analyzed using Wilcoxon test at a 5% significance level. The findings demonstrated that RQA-Integrated CM positively influenced students' critical thinking. Based on these results, it is recommended that educators utilize RQA-Integrated CM to enhance critical thinking in the classroom

Abstract

Feed is one of the important factors in fish farming, because it can account for 60–70% of the total operational costs of cultivation. The purpose of this study was to analyze the effect of providing water hyacinth (Eichhornia crassipes) fermented with Aspergillus niger as feed on the growth performance of tilapia (Oreochromis niloticus). This study used an experimental method and a Completely Randomized Design (CRD) consisting of five treatments and three replications, with the composition of P0 (commercial pellets) as the control, P1 (30% unfermented water hyacinth flour), and P2 (10%), P3 (20%), and P4 (30%) fermented water hyacinth flour. The results of this study showed that the addition of water hyacinth flour fermented with Aspergillus niger had no significant effect (P > 0.05) on tilapia protein retention. It was also known that the water quality in the tilapia maintenance media was within the optimal range.

Abstract

Sociaty 5.0 era has placed artificial intelligence (AI) and the internet of things (IoT) as fundamental aspects of human activity. The Indonesian government has paid great attention to the digitisation of learning through a curriculum that focused to use of technology, project-based learning, and the strengthening of digital competencies relevant to the needs of industry and society. However, facts in the field show that the learning tools developed by students as prospective teachers still don’t make optimal use of technology. The purpose of this study is to produce digital modules that are valid in terms of material, media, and construct and are practical for use in physics-based learning. Implications. This study used Plomp's research design, which consists preliminary research, prototyping phase, and assessment phase. The prototyping phase included Kemp's learning model design, product design, and product quality testing in the form of validity and practicality. The findings state that the validity according to experts is 0.90 (very high), the practicality according to lecturers is 0.93 (very high), and according to students is 0.92 (very high). This study is expected to improve students' pedagogical competence, encourage the optimal use of ICT, develop digital teaching material development skills, and strengthen academic character

Abstract

This study aims to analyse students’ conceptual understanding and the needs for interactive teaching materials based on a cognitive conflict model integrated with a Culturally Responsive Teaching (CRT) approach. The research was conducted through a survey in three high schools in Padang City: SMAN 4, SMAN 9, and SMAN 11. A qualitative descriptive method was used, supported by a diagnostic test comprising 15 questions classified into four categories: conceptual understanding, lack of understanding, misconceptions, and not knowing the concept. The findings indicate that students’ average conceptual understanding remains below 50%. Significant misconceptions were identified in dynamics (41.82%), while high levels of conceptual ignorance were found in kinematics (51.91%). The needs analysis shows that teachers and students require interactive and culturally relevant materials to address these persistent misconceptions and support clearer conceptual construction. The results suggest that teaching materials incorporating cognitive conflict strategies can effectively challenge students’ initial ideas, while the CRT approach contextualises physics concepts within students’ cultural experiences. In conclusion, the development of interactive e-modules integrating cognitive conflict and CRT is needed to address conceptual difficulties and improve students’ understanding of fundamental physics concepts

Abstract

Antibacterial agents are microbial metabolism inhibitors that are present in essential oils produced by Cinnamon (Cinnamomum verum) and Tamanu (Calophyllum inophyllum). The objective of this research is to investigate the secondary metabolites and the antibacterial activity of a combination of cinnamon and tamanu essential oils (CTE) against Staphylococcus aureus ATCC 6538 and Staphylococcus epidermidis ATCC 12228. The essential oils of cinnamon and tamanu were analyzed by GC–MS. The combination of the two essential oils was prepared in three different concentrations (1.25, 2.5, and 5%) with five ratios (1:1, 1:2, 1:3, 2:1, and 3:1) for each concentration. The antibacterial test was conducted using the disk diffusion method. The results of the GC–MS analysis showed that the essential oil of cinnamon contained cinnamaldehyde as the main compound (82.59%), while the essential oil of tamanu contained linoleic acid (48.29%). The antibacterial test demonstrated that the CTE at a concentration of 5% in a 3:1 ratio exhibited the highest inhibitory effect against S. aureus ATCC 6538 with an inhibition diameter of 11.25 mm and S. epidermidis ATCC 12228 with an inhibition diameter of 11.25 mm.

Abstract

This study addresses the limited exploration of mathematical concepts embedded in Minangkabau traditional food practices, despite their potential to support culturally relevant mathematics learning. The research aims to identify and describe the ethnomathematical elements found in the preparation of four traditional foods: lamang, basung cake, onde-onde, and mangkuak cake. A qualitative approach was employed using ethnographic and case study methods. Data were collected through participant observation, in-depth interviews with traditional food makers, visual documentation, and supporting literature. The data were analyzed using thematic analysis combined with mathematical and geometric identification techniques to uncover measurement, proportional reasoning, and geometric structures. The findings reveal that traditional food preparation integrates various mathematical concepts, including ratios, volume and weight measurement, symmetry, cylindrical and conical geometry, and time estimation. These concepts appear in ingredient measurement, shaping techniques, folding patterns, and cooking management, although practitioners apply them intuitively without formal notation. The study concludes that Minangkabau culinary practices represent rich sources of ethnomathematical knowledge that can be integrated into mathematics education. This integration has the potential to enhance meaningful learning, connect mathematics with students’ cultural experiences, and support the preservation of local heritage.

Abstract

This research is motivated by the low critical thinking skills of students in chemistry learning. This is indicated by students who have not been trained in analyzing a problem and a lack of involvement, so that students are not motivated to learn. Students need effective teaching materials to be actively involved in analyzing problems and motivating learning, so that E-LKPD based on Socio-Scientific Issues is expected to be a learning innovation. This study aims to measure the effectiveness of E-LKPD based on Socio-Scientific Issues in acid-base learning on critical thinking and student learning motivation. E-LKPD is presented via the web Liveworksheets as an interactive medium. The type of research used is a quasi-experiment with a nonequivalent group pretest-posttest research design. The study was conducted in class XI IPA 8 and XI IPA 1 SMAN 4 Pekanbaru consisting of 90 students. Data analysis used the Normality test, t-test, and N-gain test. The results of the analysis for critical thinking obtained an N-gain of 0.6586 in the control class and 0.7509 in the experimental class. Meanwhile, for learning motivation, the N-gain obtained was 0.2537 in the control class and 0.4548 in the experimental class. Furthermore, the results of the t-test showed that there was a significant difference between critical thinking skills and learning motivation in the control class and the experimental class. Critical thinking skills and learning motivation have a positive relationship as evidenced by the sig. value < 0.05 with a Pearson correlation value of 0.419, thus E-LKPD based on Socio-Scientific Issues is effective in improving critical thinking skills and learning motivation in acid-base learning.
