Abstract

The Komodo dragon (Varanus komodoensis), the largest living lizard, plays a crucial role in its ecosystem. Understanding its gut microbiota is essential for assessing its digestive efficiency and immune function, yet little is known about the microbial communities within its gastrointestinal system. This study aimed to analyze the gut microbiota of wild and captive Komodo dragons using metagenomic sequencing and to explore its role in digestion and immunity. Fecal and gut content samples were collected from 12 wild and 10 captive Komodo dragons. High-throughput sequencing of the 16S rRNA gene was used to characterize the microbial diversity. The results revealed significant differences in microbiota composition between wild and captive individuals, with wild dragons displaying higher microbial diversity. Dominant phyla in wild Komodo dragons included Firmicutes and Bacteroidetes, while Escherichia and Klebsiella were more prevalent in captive individuals. Additionally, microbial diversity was positively correlated with immune-related gene expression, suggesting that the microbiota plays a role in immune modulation. These findings highlight the importance of diet and environmental factors in shaping the gut microbiota, with implications for conservation and breeding programs. Further research should focus on functional profiling and exploring other microbial groups to fully understand the microbiome's impact on health

Abstract

The community of believers in the One Almighty God in Indonesia has undergone significant transformation, especially after the legal recognition through the Constitutional Court ruling in 2017. This transformation not only covers social, cultural, and economic aspects, but also involves changes in the structure of collective identity and negotiation of their position amidst the dominance of the majority religion. This article analyzes the transformation process through a sociological approach, referring to the theories of functionalism, social conflict, and symbolic interaction. The main focus includes identity dynamics, social interaction patterns, integration challenges, and the role of belief organizations in preserving local traditions while adapting to modern norms. This analysis also highlights how legal recognition has opened up space for believers to strengthen their position in society, although challenges such as social stigma and marginalization are still faced. This transformation, ultimately, reflects efforts to create social harmony and maintain diversity in a pluralistic Indonesian society.

Abstract

The teaching of English as a foreign language in Indonesia continues to face challenges, particularly in identifying the most effective instructional approach. Previous studies have shown varying results when comparing communicative and grammar-based methods in language acquisition. This study aims to compare the effectiveness of two dominant approaches: the Communicative Language Teaching (CLT) method and the Grammar-Translation Method (GTM) in improving English proficiency among secondary school students in Indonesia. Employing a quasi-experimental design, this research involved 120 students divided into two equal groups, each receiving instruction based on one of the approaches over a period of 12 weeks. Pre-tests and post-tests were administered to measure students’ progress in reading, writing, listening, and speaking skills. The results indicated that the CLT group significantly outperformed the GTM group, particularly in speaking and listening components, while the GTM group showed marginally better results in grammar and reading comprehension. The findings suggest that while both methods have merits, CLT offers a more balanced improvement in communicative competence. This study contributes to the ongoing discourse on English pedagogy in EFL contexts and provides evidence-based recommendations for curriculum development in Indonesian schools.
