Abstract

The research explores the correlation between critical thinking skills and argumentation skills are still rarely found, especially in Biology lectures. Building an argument is actually a representation of students’ critical thinking skills and cognitive structure. This study investigates the correlation between critical thinking skills and argumentation skills among biology students exposed to RQA, ADI, WE-ARe, and conventional teaching strategies. The samples of this research were Biology education students in the fourth semester undergoing Animal Physiology. The data were analyzed by using regression analysis. Using regression analysis, significant correlation was only found in the ADI group (R² = 0.192, p < 0.05). These findings underscore the importance of using inquiry-driven models to enhance students' reasoning abilities. The results of this research are most likely affected by the students’ academic ability

Abstract

Covid-19 prevention has also entered a new era with the availability of the Covid-19 vaccine, which has undergone clinical trials and has been mass-produced to enhance immunity. However, the administration of vaccinations has resulted in unexpected reactions known as Adverse Events Following Immunization (KIPI). This phenomenon suggests that low vaccination rates may be associated with perceived dangerous KIPI reactions, which can be attributed to doubts and misinformation about vaccines. This study used a correlation analytical research design with a retrospective method. The population of this study consisted of all individuals who had received vaccination and experienced KIPI reactions in the working area of Teja Health Center, totaling 30 people. The characteristics of the respondents, as seen from their allergic history and vaccine stages, showed a significant correlation (p = 0.027 < 0.05). The p-value for vaccine stages was 0.000, indicating a significant relationship with the severity of KIPI reactions in Covid-19 vaccine recipients. However, age and gender were not significantly associated with the severity of KIPI reactions. The severity of KIPI reactions in Covid-19 vaccine recipients has a significant correlation with the characteristics of the respondents, as seen from their allergic history and vaccine stages.

Abstract

Base Transceiver Station (BTS) towers are highly vulnerable to lightning strikes. A lightning strike is a moving electric charge that generates an electric field and a magnetic field, both of which are vector quantities, and induces voltage around the tower. The closer to the tower, the greater the values of the electric field, magnetic field, and induced voltage generated. A 49-meter highs tower in Mataram City is located 25 and 300 meters from residential areas and public facilities. The metabolism of living organisms, such as blood circulation, nerve function, heart rate, lung function, cell growth, and cell division, are also vector quantities. Exposure of living organisms to external electric fields exceeding the threshold of ≥10 kV/m can disrupt their metabolism. It is crucial to determine the magnitude and direction of the electric field vector caused by lightning strikes on BTS towers and how it affects living organisms around the tower. Observations are based on Coulomb's Law and its derivative theories on electric fields. The peak lightning current in tropical areas ranges from 10 to 100 kA, with a frequency of 200 kHz. The electric field intensity at distances of 25 and 300 meters is 58.30, 584.50, 4.86, and 48.71 kV/m, respectively. These results indicate that a distance of 25 meters from the tower is not safe from exposure to high electric field intensity values.

Abstract

Science process skills are one of the important skills that students must have. This is because it can improve students' basic competencies, which include the formation of scientific attitudes, as well as their ability to solve problems. The STEM (Science, Technology, Engineering, Mathematics) approach is considered capable of encouraging students to improve these skills and solve problems in an integrated manner from an early age. This is because STEM is an approach that integrates science, technology, engineering and mathematics into one learning process, so that it will focus students on solving problems related to everyday life. The purpose of this article is to examine how the application of the STEM approach improves students' science process skills. The method used in this article is a systematic literature review. Literature reviews are carried out by analyzing various references related to the research topic. Data collection was carried out by following the PRISMA guidelines sourced from two databases, namely Google Scholar and Scopus, with a time span of 2015–2024 through the assistance of the Publish or Perish 8 (PoP) application. A total of 15 articles were obtained which were used as research data that were analyzed. The results of this study concluded that the application of the STEM approach can improve students' science process skills positively. Furthermore, teachers must be able to improve their skills in applying this STEM approach in teaching and learning activities in the classroom.

Abstract

Diarrhea and dysentery are major health problems in Indonesia, with Shigella sonnei being one of the primary causative agents. Excessive use of antibiotics has led to bacterial resistance, necessitating safe and effective alternative treatments. This study evaluates the antibacterial potential of extracts from brotowali (Tinospora crispa), wuluh starfruit (Averrhoa bilimbi), and bay leaf (Syzygium polyanthum) against Shigella sonnei. Plant materials were sourced from Kakap Village, West Kalimantan, and extracted using maceration with 96% ethanol. Phytochemical tests were conducted to identify active compounds in the extracts, while antibacterial activity was assessed using the disk diffusion method at extract concentrations of 20%, 40%, 60%, and 80%. All three plant extracts contained active compounds such as alkaloids, flavonoids, phenolics, and tannins. Antibacterial tests showed that all extracts exhibited antibacterial activity against S. sonnei, with bay leaf extract at 80% concentration demonstrating the largest inhibition zone of 20.3 mm. Statistical analysis indicated that increasing extract concentration enhanced antibacterial effectiveness. This study suggests that extracts of brotowali, wuluh  starfruit, and bay leaf have the potential to be effective natural antibacterial agents against S. sonnei.  Further research should focus on understanding the mechanisms of action and exploring the potential clinical applications of these plant extracts. Additionally, integrating these findings into science education can enhance students' scientific literacy and provide practical examples of using natural resources in addressing health issues.

Abstract

Carrots are one of the most popular plants in Indonesia. In addition to being a plant with a flavor favored, carrots also contain various bioactivities that can be utilized for health. This study aims to investigate the bioactivity of carrot extract, which includes antioxidant, antibacterial, and antifungal. The method used in this study is DPPH, which aims to determine antioxidant activity, and the disc diffusion method to determine antibacterial and antifungal activity. Carrot extract was obtained using the maceration method with a ratio of 1:10 using ethanol solvent 96% for the antioxidant test, while for the antibacterial and antifungal tests, acetone solvent was used. The extracted carrots yielded a yield of 10.1% (v/b). Based on the results of phytochemical screening, it is known that carrots contain flavonoids, saponins, tannins, and alkaloids, as well as functional groups indicating the presence of beta-carotene in carrots through FTIR. Carrots show weak antioxidant activity with an IC50 value of 125.944 ppm. The inhibitory activity of carrot extract during 24 hours of observation are concentration 40% (0.7 mm), 60% (0.77 mm) and 80% (0.85 mm). Meanwhile, in the antifungal test, carrot extract showed negative results at concentrations 60 and 80%, while at a concentration of 100% showed an inhibition zone of 0.835 mm.

Abstract

This study investigates the variations in the preparation of Semester Learning Plans (SLP) for the Basic Chemistry 1 course across 19 chemistry education programs at 31 universities in Indonesia. The study focuses on key aspects such as material coverage, learning methods, evaluation techniques, book references, and learning media used in each SLP. Using a qualitative descriptive approach and content analysis of 19 SLP documents, the study reveals significant diversity in the covered topics, teaching methods, and evaluation techniques employed across institutions. Core topics like stoichiometry and atomic structure are taught universally, but there is notable variation in specialized content such as green chemistry, air pollution, and tropical rainforests. The learning methods are primarily interactive, with group discussions and project-based learning being the most dominant. However, no program explicitly integrates the scientific method into its curriculum. Evaluation techniques vary, with most programs combining written exams and practical projects. This research concludes that the variations in SLP reflect institutional efforts to align curricula with local needs and global trends. It recommends expanding the sample scope in future studies and including qualitative data such as interviews with lecturers and student surveys for a more comprehensive understanding of how SLP impacts learning outcomes.
