Abstract

Persistent challenges in algebraic learning among Indonesian junior high school students, characterized by performance below minimum mastery criteria, necessitate innovative pedagogical interventions. This study examined the effectiveness of integrating Problem-Based Learning (PBL) with the wizer.me digital platform in enhancing Year 7 students’ algebraic competence within the context of Sustainable Development Goal 12 (sustainable consumption and production). Employing a quantitative one-shot case study design, the research involved 24 randomly selected students from a junior high school in Banda Aceh during the 2024/2025 academic year. Data were collected through a validated post-test instrument comprising four essay questions contextualized within SDG 12 scenarios, assessing conceptual understanding, mathematical modeling, and problem-solving skills. Statistical analyses revealed significant learning outcomes, with students achieving a mean score of 76.33 (SD = 9.78), substantially exceeding minimum mastery criteria (t = 38.224, p < 0.001). Results demonstrate that the synergistic combination of PBL, interactive digital technology, and authentic sustainability contexts effectively facilitates algebraic mastery while cultivating global citizenship awareness. These findings suggest that educators should integrate technology-enhanced problem-based approaches and SDG frameworks into mathematics curriculum to enhance engagement, conceptual understanding, and real-world relevance. Future research should employ larger samples and experimental designs to establish robust causal evidence regarding the scalability and long-term impacts of such interventions.

Abstract

This study aims to design multifunctional clothing based on sustainable fashion, specifically intended for career women, with consideration of long-term functionality, flexibility, and the ability to express self-identity. The background of this research is rooted in the need for career women to have clothing that is not only practical and aesthetically pleasing but also environmentally friendly and capable of representing personal character. A quantitative method was used, involving five panelists consisting of designers, academics, and professional women as respondents. The researcher developed four sets of multifunctional black clothing designs: (1) a sleeveless blazer with long pants, (2) a detachable-sleeve blazer with waist accents, (3) a blazer with ruffles on the collar and cuffs, and (4) pants that can be converted into a skirt. Evaluations were conducted based on four main aspects: quality dimension (comfort, material strength, construction), design principles (form harmony, aesthetics, function), sustainability (eco-friendly materials, durability, maintenance), and self-identity (style alignment with user personality). The analysis results show that the second design received the highest overall score. The average score across all four designs was 89.6%, with sustainability and design principles emerging as the most prominent aspects. In conclusion, multifunctional clothing based on sustainable fashion proves to be a suitable solution for modern career women, fulfilling the needs for efficiency, style, and deep self-expression, while also supporting sustainable fashion practices
