Abstract

The ethnopharmacological significance of Elaeocarpus longifolius (Jambu Wer), an indigenous medicinal plant of the Tengger Tribe, remains underexplored. This study evaluates the antibacterial and phytochemical properties of E. longifolius fruit extracts using ethanol, n-hexane, ethyl acetate, and chloroform as solvents. Antibacterial activity was assessed against Escherichia coli and Shigella dysenteriae, pathogens commonly associated with severe diarrhea, using the agar disk-diffusion method. Phytochemical screening was conducted using reagent-based tests and thin-layer chromatography (TLC). The ethanol extract exhibited the highest antibacterial activity, with inhibition zones exceeding 20 mm against both bacterial species. Phytochemical analysis revealed the presence of alkaloids, flavonoids, and tannins (compounds known for their pharmacological properties). These findings highlight the potential of E. longifolius ethanol extract as a promising natural therapeutic candidate for the development of Fitofarmaka targeting diarrheal diseases.

Abstract

The nature influence of speaking anxiety on foreign language (FL) learning settings has been established. In addition, research acknowledges the relevance of speaking performance in affecting individual predisposition to experience anxious feelings. However, few studies examine the Indonesian college students' anxiety influencing factors, mainly when speaking English. Data strategies employed a parallel design combining quantitative and qualitative methods mixing a closed-ended Likert-scale questionnaire with an in-depth interview. Twenty-eight college students responded online via Google Form to the questionnaire, while in addition, the in-depth interviews lasted 45-60 minutes with six college students. The results indicate that learning situations in classroom activities revolve around how teachers teach, college students' self-confidence, belief in language learning experiences, and excessive learning material are nature-related prominence factors of college students' anxiety in speaking English. In contrast, a lack of college students' preparation has no effect. Examined are the means through which this research contributes to the advancement of understanding and comprehension of previously unidentified components that influence college students' speaking anxiety.
