ECOLINGUISTIC STUDY WITH AI-BASED FRAMEWORK ON NIAS MEDICINAL PLANTS

Made Sani Damayanthi Muliawan — 2026-03-03

Indigenous medicinal plant knowledge constitutes a crucial component of ecolinguistic systems, as it is embedded in linguistic expressions that reflect ecological relationships, healing practices, and cultural values. However, this knowledge is increasingly threatened by language shift and insufficient documentation, particularly within low-resource indigenous communities. This study develops an AI-based ecolinguistic framework to systematically document and represent Nias ethnomedicinal knowledge by integrating ethnobotanical field data with culturally grounded artificial intelligence approaches. Qualitative data were obtained through semi-structured interviews with traditional Nias healers, resulting in the identification of fifteen commonly used medicinal plant species. To assess cultural salience and communal consensus, the study applied the Relative Frequency of Citation (RFC) index. The quantitative findings reveal an uneven distribution of cultural prominence among the documented species. Notably, Gundre and Mbulu Nazalöu emerged as the most frequently cited plants (FC = 14; RFC = 0.93 each), indicating their central role within the Nias ethnomedical knowledge system. The documented knowledge was subsequently structured using a Knowledge Graph model and enhanced through a Retrieval-Augmented Generation (RAG) architecture to enable contextualized, culturally sensitive knowledge representation. The proposed framework demonstrates how artificial intelligence can support the preservation, organization, and revitalization of endangered indigenous medicinal knowledge while maintaining its ecolinguistic integrity.

PEMAHAMAN BAHASA: TELAAH KONSEPTUAL TENTANG DEFENISI DAN CIRI-CIRI BAHASA INDONESIA

Melisha Ayudia — 2026-03-17

Language is the primary means of communication used by humans to convey ideas, thoughts, and feelings in social life. In the Indonesian context, the Indonesian language plays an important role as both the national language and the official state language, functioning as a unifying tool for a society with diverse cultural backgrounds and regional languages. This study aims to conceptually examine the definition of language and the characteristics of the Indonesian language from a linguistic perspective. The research method employed is a qualitative approach using a library research design through the analysis of various relevant scientific literature sources. The results of the study indicate that the Indonesian language possesses several main characteristics: it is systematic, arbitrary, productive, dynamic, and conventional. These characteristics demonstrate that Indonesian is a structured linguistic system capable of developing in accordance with the communication needs of society. Therefore, understanding the concepts and characteristics of the Indonesian language is essential to support proper and correct language use in various fields of life, particularly in education and academic communication.

REALISASI FONOLOGIS BUNYI BAHASA INDONESIA DALAM TUTURAN PENUTUR: ANALISIS SISTEM PELAFALAN

Rahma Indah Lestari — 2026-03-31

This study aims to analyze the phonological realization of Indonesian language sounds in speakers' speech and to identify the factors influencing the pronunciation system. The study employs a descriptive qualitative approach using library research methods and content analysis techniques. The findings indicate that phonological realization in speakers' speech is dynamic and varied, influenced by the first language which consistently shapes articulatory patterns. Pronunciation variations manifest in the form of phoneme substitution, sound deletion, sound structure simplification, as well as differences in intonation and word stress. From a phonological perspective, such variation is part of a natural linguistic adaptation process that occurs in multilingual communities, rather than merely a language error. Furthermore, phonological realization has significant implications for communication effectiveness and Indonesian language learning. An understanding of phonological variation is expected to assist educators in designing more contextual and effective learning strategies for students with diverse regional language backgrounds.

THE ROLE OF THE NIAS LANGUAGE IN STRENGTHENING SCIENCE CONCEPTS WITHIN A LOCAL CULTURAL CONTEXT IN SENIOR HIGH SCHOO

This study aims to examine the use of the Nias language as a medium for strengthening science (Physics) concepts in Grade X at SMA Negeri 1 Teluk Dalam within the context of local culture. The research focuses on how integrating local language can improve students’ understanding of abstract physics concepts, particularly motion and force. A mixed-method approach was applied, combining quantitative data from pretest and posttest results with qualitative data from observations, questionnaires, and interviews. The findings show that students who learned physics using the Nias language achieved higher learning outcomes compared to those who used conventional instruction. The use of local language made learning more contextual, meaningful, and easier to understand. It also increased students’ motivation, participation, and confidence during the learning process. Furthermore, students were able to relate physics concepts to their daily life experiences and cultural environment. This study concludes that the integration of the Nias language in physics learning is an effective strategy to improve conceptual understanding and scientific literacy while preserving local cultural identity. Therefore, culturally based learning approaches should be considered in science education to enhance both academic achievement and cultural awareness among students.
