Mathematics is often perceived as an abstract, universal, and culture-free discipline, presented in formal symbols and rigid procedures that appear distant from learners’ everyday realities. This research investigated fractal concepts in ethnomathematics in relation to the Minangkabau songket textile. This research employed a qualitative case study design. Data were collected using a document checklist of the songket and a semi-structured interview. Data were analyzed using document analysis and thematic analysis. The research population was the Minangkabau songket textile, and the sampling method was purposive; three songket motifs from Pandai Sikek, West Sumatra, were selected. The results reveal repeated patterns of self-similarity, iteration, recursion, symmetry, and statistical variation, which are similar to the structures seen in nature. These patterns are not the result of formal mathematical calculation but arise from indigenous knowledge grounded in the Minangkabau philosophy alam takambang jadi guru, where nature serves as the primary source of learning. Beyond their aesthetic function, the fractal properties of songket motifs serve as visual metaphors for cultural continuity, social harmony, and the intergenerational transmission of values. This research is limited to songket produced by Pandai Sikek in West Sumatra. This study reinforces the notion that traditional cultural products are not only artistic expressions but also repositories of sophisticated mathematical knowledge.

This research explores how Micro, Small, and Medium Enterprises (MSMEs) in West Sumatra employ code-switching in their advertising discourse to construct linguistic identity, express cultural belonging, and project entrepreneurial modernity. Using Fairclough’s Critical Discourse Analysis (CDA) as the analytical framework, this study examines linguistic features, forms of code-switching, and the underlying ideological meanings within promotional banners and billboards that combine English and Indonesian. The findings reveal that code-switching serves as more than a marketing strategy it functions as a socio-symbolic practice through which entrepreneurs negotiate between local authenticity and global aspirations. The frequent use of English, despite notable errors in diction, spelling, and syntax, underscores its symbolic power as a marker of prestige and progress in the post-pandemic economic landscape. However, these linguistic inaccuracies also indicate challenges in language proficiency and access to educational resources, exposing power asymmetries between local entrepreneurs and global linguistic norms. From a sociolinguistic standpoint, code-switching embodies both empowerment and vulnerability: it enables small businesses to gain visibility in global markets while simultaneously revealing structural inequalities in linguistic capital. The study concludes that language operates as a key site of negotiation where identity, economy, and ideology intersect. It recommends enhancing critical language awareness and multilingual marketing literacy in MSME training programs. Future research is encouraged to examine digital advertising discourses to understand how linguistic entrepreneurship evolves in online spaces. This study contributes to the growing body of literature on sociolinguistics, linguistic entrepreneurship, and the politics of language in Indonesia’s evolving marketplace.

Speaking is often regarded as one of the most challenging skills for English as a Foreign Language (EFL) learners in Indonesia due to limited exposure, lack of authentic oral communication opportunities, anxiety, and low self-confidence. This study aims to determine whether Asian Parliamentary Debate (APD) activitiesas extracurricular can significantly improve students' speaking skills at SMAN 1 Lubuk Sikaping. A quantitative pre-experimental One Group Pre-test and Post-test Design was employed involving 31 students of the 2025/2026 English Debate extracurricular program. The treatment consisted of four structured APD sessions conducted in Weeks 2–5, preceded by a pre-test in Week 1 and followed by a post-test in Week 6. Speaking performance was measured using Hughes's (2003) rubric covering five components: grammar, vocabulary, pronunciation, fluency, and comprehension. A paired sample t-test revealed a statistically significant improvement in overall speaking scores (pre-test M = 52.26, post-test M = 74.00, t = −14.775, p = 0.000) and across all five components. These findings confirm that Asian Parliamentary Debate is an effective instructional strategy for enhancing EFL students' speaking skills and can serve as an alternative approach in speaking instruction.
