“…It is estimated that there are approximately 90,000 plant species in Indonesia, of which 9,600 are recognized for their medicinal properties. About 300 of these species are utilized by the traditional medicine sector as raw materials for remedies [2]. According to the World Health Organization (WHO), 80% of populations in developing countries rely on medicinal plants for traditional medicine practices [3], and Indonesia is prominent among these nations.…”

The present study evaluates the antibacterial efficacy of ethanolic extracts from Delonix regia leaves against diarrhea-inducing bacteria Escherichia coli and Salmonella typhimurium. Preliminary phytochemical screening revealed that D. regia leaves comprise flavonoids, alkaloids, saponins, tannins, phenolics, and terpenoids. Fourier Transform Infrared Spectroscopy (FTIR) analysis identified various functional groups in the D. regia leaf extract, including O-H, C-H, C=O, C=C, C-C, C-O, and C-O-C. Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (LC-MS/MS) analysis further confirmed the presence of 16 distinct compounds comprising amino acids, alkaloids, phenolics, flavonoids, terpenoids, anthraquinones, n-acyl pyrrolidines, and fatty acids. The disc diffusion method (Kirby-Bauer) was employed for the antibacterial tests. The extracts of D. regia leaves at concentrations of 25%, 50%, 75%, and 100% generated inhibition zones measuring 5.26 mm, 6.37 mm, 7.27 mm, and 10.18 mm against E. coli, and 5.05 mm, 7.01 mm, 8.77 mm, and 10.04 mm against S. typhimurium, respectively. The commercial antibiotic ciprofloxacin (a positive control) produced inhibition zones of 30.02 mm for E. coli and 28 mm for S. typhimurium. The negative control, consisting of 10% ethanol, showed no inhibitory effect on bacterial growth. These findings indicate that the ethanolic extract of D. regia leaves possesses antibacterial properties against E. coli and S. typhimurium. It is likely that secondary metabolite compounds, such as flavonoids and phenolics, contribute significantly to the observed antibacterial activity

“…Ethnochemistry is the knowledge based on local culture in everyday life viewed from the chemistry perspective (Asda, 2023;Singh & Chibuye, 2016). There have been etnochemistry studies to identify the medicinal plants used by the people in Samadua, South Aceh (Gani et al, 2022) and Kalimantan (Maharani & Fernandes, 2021). The identification of local culture as a source of chemistry learning from the Baduy community in Banten (Nursaadah et al, 2017), Javanese in Bantul (Azizah & Premono, 2021), and Sasak in Lombok (Efendi & Muliadi, 2023;Wahyudiati & Fitriani, 2021) were utilized etnochemistry approach.…”

Perceiving culture in the globalization era is challenge for the Malay community. The best way to solve it is to integrate ethnochemistry into chemistry learning at the school. The research aims to develop acid-base microblogs based on the ethnochemistry of the Malay community. Three Stages Research and Development (TSRD) model was conducted in this study which consists of 3 steps: planning, development, and dissemination. The subjects of this research were the students of XI MIPA class at SMAN 11 Pontianak, SMA Muhammadiyah 1 Pontianak, and MAN 3 Pontianak. The validity assessment and response sheet were used to collect data in this study. The results of the acid-base microblogs based on the ethnochemistry of Malay culture obtained 0.85 of validity from the expert judgment in the very high category. An excellent response was given by the student to the microblog, with a percentage of 82.28%. Based on the study results, the ethnochemistry microblogs have been declared very valid to arouse preserving culture.

This research comprehensively analyzes students’ Chemistry Learning Experience (CLE) during the COVID-19 pandemic, comparing online learning experiences with traditional face-to-face instruction in the post-pandemic phase. Employing a quantitative approach and leveraging the Rasch model, the study focuses on capturing the nuances of individual student perceptions, an aspect often overlooked in group-centric statistical analyses. One hundred students (49 males and 51 females) participated in both study phases. Segmented into behavioral tendencies, content perceptions, and specific learning needs, the evaluation tools provided insights into the students’ CLE across the two instructional modalities. Results from the stacking analysis revealed a positive shift in CLE post-pandemic, with students demonstrating a better grasp of and attitude toward chemistry in face-to-face settings. Racking analysis further underscored the changing difficulty perceptions of specific content items across the two learning environments. Gender-based patterns in CLE were also evident, with male students expressing a more favorable view of online learning during the pandemic than their female counterparts. The research findings advocate for a blended learning approach, harnessing the strengths of both online and traditional instructional methods. Furthermore, insights into gender-specific learning experiences emphasize the need for inclusive and adaptive teaching strategies, ensuring optimal learning experiences for all students. The study underscores educators’ and students’ resilience and adaptability in navigating the challenges of the pandemic. It offers valuable insights for future educational strategies in chemistry education.
