This study aims to analyze the problems of implementing the Independent Curriculum in mathematics learning and evaluate its effectiveness at the elementary and secondary education levels. The research method used literature study and policy analysis with a descriptive-analytical approach. The results of the study indicate that the main problems include: (1) teachers' limited understanding of the philosophy and implementation of the Independent Curriculum, (2) unpreparedness of educational technology infrastructure, (3) challenges in developing contextual teaching modules, (4) minimal ongoing training for educators, and (5) gaps between curriculum expectations and realities on the ground. The evaluation shows that the implementation of the Independent Curriculum has positive potential in increasing students' creativity and critical thinking skills, but requires systematic support in terms of teacher capacity development, provision of adequate learning resources, and an adaptive evaluation system. This study recommends the need for the development of ongoing training programs, the provision of integrated digital learning platforms, and the development of assessment tools that align with the principles of differentiated learning.</em></p>2025-12-31T00:00:00+07:00Copyright (c) 2025 Ellis Mardiana Panggabeanhttps://www.jurnal.larisma.or.id/index.php/EMJU/article/view/1381Application of the TOPSIS Method for Electronic Supplier Selection Based on Multi-Criteria2025-11-26T08:00:33+07:00Chairunnisa Selvianiicaanisaa1502@gmail.comDewi Aslamiah Nasutionicaanisaa1502@gmail.comNabila Ameliaicaanisaa1502@gmail.comNadya Putri Zulidaicaanisaa1502@gmail.comNisya Aulia Salsabilaicaanisaa1502@gmail.comMuhammad Romi Syahputraicaanisaa1502@gmail.com<p>Supplier selection in the electronics industry is highly complex due to the numerous and often conflicting assessment parameters. These parameters include economic aspects, product quality, delivery reliability, and environmental impact. This study uses the TOPSIS method to objectively rank suppliers based on four main criteria with their respective weights: product quality (30%), price (25%), delivery accuracy (25%), and sustainability (20%). Simulation data is used as an example to demonstrate how this method is applied. The assessment results show that PT Green Component (S5) is ranked first with a closeness coefficient of 0.7777, followed by PT Techno Supply (S3) with a score of 0.7577. Sensitivity tests using four weighting change scenarios show stable results, with S5 and S3 remaining in the top two rankings. These findings indicate that balancing product quality and environmental sustainability is a key factor in differentiating competitive advantage in the modern supply chain management era. The TOPSIS approach has proven effective as a structured and transparent framework to assist decision-making in the supplier selection process in the electronics industry.</p>2025-12-04T00:00:00+07:00Copyright (c) 2025 Chairunnisa Selviani, Dewi Aslamiah Nasution, Nabila Amelia, Nadya Putri Zulida, Nisya Aulia Salsabila, Muhammad Romi Syahputra
