Abstract:External evidence can make retrieval-augmented generation (RAG) more informative, yet retrieved passages also provide a path for adversarial instructions to enter the model context. We examine that path in an English-Indonesian…
onesian RAG system and track cross-lingual indirect prompt injection separately at retrieval, reranking, and generation. The experiment starts from 75 semantic items and evaluates every item in eight query/body/payload language combinations, for 600 paired trials. Qwen3-Embedding-0.6B and BGE-M3 produce top-20 candidate sets, BGE-reranker-v2-m3 reduces each set to five documents, and Qwen3-0.6B answers from the resulting context with either a standard prompt or an explicit trust-boundary prompt. Statistical uncertainty is estimated by resampling semantic items, and paired binary outcomes are modeled with generalized estimating equations. Poison documents reached the top 20 in 80.50% of Qwen trials and 37.67% of BGE-M3 trials (odds ratio 6.94, 95% CI 4.53-10.63). Top-five exposure was 18.50% and 16.17%, respectively. Standard end-to-end attack success was 6.33% for Qwen and 6.00% for BGE-M3; boundary-aware prompting lowered both rates to 1.33%, with no canary false positives. The results indicate that multilingual RAG security depends on several linked stages rather than generation alone.
Abstract:Communicative competence has become an essential competency for business education students in response to the growing demands of multilingual, multicultural, and technology-driven workplaces. However, previous studies have…
ave generally examined bilingual competency, collaborative learning, and communicative competence as separate constructs, providing limited understanding of their integrated relationships. This study aimed to develop an Integrated Communicative Competence Model for business education through the synthesis of previous empirical studies and recent international literature. A conceptual research design employing an integrative evidence synthesis approach was used to analyse empirical findings on bilingual competency, pair interaction, communicative competence, and professional readiness. The synthesis demonstrates that bilingual competency provides the linguistic and intercultural foundation for effective communication, while pair interaction functions as a collaborative learning mechanism that strengthens authentic communication practices. The interaction of these dimensions enhances communicative competence, which subsequently improves students' professional readiness and graduate employability in multilingual business environments. The proposed model contributes to communication studies by integrating bilingual competency and collaborative learning into a unified conceptual framework and provides practical guidance for curriculum development and communication-oriented learning in business education.
Abstract:The relationship between linguistics and language education is particularly interesting to follow. In language education, especially English, linguistics provides information on language rules and structure knowledge. However,…
wever, due to the notion that teaching English language must be taught in a multilingual environment and intercultural approach, linguistics must also provide a complete description of language. To describe language in use, discourse is the key. To linguistic students, discourse is a familiar term, while to some language education students, the term may be unfamiliar. This raises many issues, including what is discourse. Is it important to learn? Is it relatable to language education, particularly English? To answer these questions, we need to take a glimpse of discourse analysis.

ntains descriptions of MSME products in several languages. This catalog aims to facilitate communication between MSME actors and inter-national consumers, as well as increase the visibility and competitiveness of MSMEs in the global market. In addition, this digital catalog is also expected to contribute to the preservation of regional languages, such as Javanese, which are becoming endangered. The methods used include a preparatory stage in the form of field analysis, then a needs analysis stage, and continued with the stage of making a multi-language online catalog. The catalog development process involved training for MSME players, creating attractive and relevant product descriptions, and developing an online catalog platform. As a result, this catalog has succeeded in increasing sales and expanding the market reach of MSMEs in Potrobangsan Village.

Abstract:This study investigates the role of the internet in bridging language gaps and enhancing English as a Foreign Language (EFL) instruction within Solo's multilingual context. The focus is on how internet resources aid students…
ents in navigating between Bahasa Jawa, Bahasa Indonesia, and English, reflecting the multilingual dynamics of EFL classrooms. Utilizing a qualitative approach, semi-structured interviews were conducted with students from grade XII public senior high schools in Solo, Central Java. The findings reveal that the internet plays a significant role in facilitating language learning by providing access to diverse resources and interactive platforms. It is reported that internet tools help them create more engaging and culturally relevant lessons, which cater to the multilingual backgrounds of the students. Students highlighted that online resources offer immediate feedback, diverse learning materials, and opportunities for practicing English in real-world contexts, which are crucial for mastering a foreign language. Moreover, the study shows that the internet supports students in developing digital literacy skills, which are essential for effective language learning in the 21st century. The use of internet-based learning tools helps students seamlessly transition between languages, enhancing their overall language proficiency and confidence in using English. This research underscores the importance of integrating internet resources in EFL education to address the unique linguistic needs of students in multilingual settings. Future studies should explore the long-term impacts of internet use on language acquisition and its potential integration with traditional teaching methods to create a more holistic and effective EFL learning environment.
Abstract:Central Java–West Java border communities live in a multicultural environment where Javanese and Sundanese cultures meet, forming distinctive multilingual communication practices. The use of Javanese, Sundanese, and Indonesian…
donesian in everyday life functions not only as a means of communication, but also as a representation of the community's social identity. This study aims to analyze the multilingual communication practices of Central Java–West Java border communities and to explain the role of language in representing community social identity. The study uses a descriptive qualitative approach with a literature review method supported by social-contextual reflection. Data were obtained from various scientific sources discussing multilingual communication, social identity, intercultural communication, bilingualism, and multilingualism. The analysis was carried out through the stages of data reduction, theme categorization, meaning interpretation, and conclusion drawing. The findings show that border communities flexibly use Javanese, Sundanese, and Indonesian according to the context of interaction, social relations, and communication needs. The practices of code switching and code mixing are important parts of daily communication as forms of social and cultural adaptation. In addition, language use functions as a symbol of cultural identity, a means of identity negotiation, and a mechanism of social integration in a multicultural environment. The findings affirm that multilingual communication is a representation of dynamic social identity and reflects the ability of border communities to maintain social harmony amid cultural diversity.
