Abstract

The rise of “post-Western” political discourse presents a significant rhetorical puzzle: how do nationalist leaders perform sovereign strength while simultaneously adhering to the multilateral norms of institutions like the United Nations? This article investigates this “sovereigntist’s dilemma” through a case study of Indonesian President Prabowo Subianto’s 2025 UN General Assembly address. While previous research using Systemic Functional Linguistics (SFL) has analyzed Appraisal systems in isolation, this study argues that such fragmentation misses the functional unity of political rhetoric. Employing a rigorous “co-instantiation” methodology, we mapped the simultaneous bundling of evaluative resources across the speech (N=335). The findings reveal a dominant “rhetorical trialectic” comprising Attitude: Judgement (26.9%), Engagement: Contraction (23.9%), and Graduation: Force (21.5%). We argue that this specific configuration constructs a stance of “moral sovereigntism,” wherein the speaker co-opts the language of global morality to justify nationalist capacity. By reframing national strength not as a threat to multilateralism but as the only vehicle for achieving it, the speech resolves the ideological contradiction. This study contributes a replicable methodological protocol for analyzing the bundled nature of political stance.

Abstract

This research is motivated by the fact that many elementary school students still experience difficulties in understanding basic mathematical concepts, especially in long multiplication operations. These difficulties often lead students to make various errors in understanding place value concepts and calculation procedures, which impact low learning outcomes and student numeracy skills. This study aims to analyze the types of errors made by elementary school students in solving long multiplication problems based on Kastolan's theory through a Systematic Literature Review (SLR) approach. The method used is a Systematic Literature Review (SLR) by reviewing 10 relevant scientific articles published between 2021 and 2025 from the Google Scholar database. Data analysis was conducted by classifying errors into three categories according to Kastolan's theory: conceptual errors, procedural errors, and technical errors. The results show that the most dominant error made by students is conceptual error with an average of 52.7%, followed by procedural error at 45.45%, and technical error at 42.13%. These findings indicate that low understanding of basic multiplication and place value concepts is the main factor causing student errors, which then leads to procedural and technical calculation errors. The results of this study are expected to serve as a reference for teachers in designing more effective learning strategies to improve students' understanding of mathematical concepts.

Abstract

This study aims to evaluate and synthesize previous research findings regarding the use of the role-playing learning model in enhancing science concept understanding among elementary school students, particularly on the topic of food chains. This study employed a Systematic Literature Review (SLR) method using the PRISMA 2020 protocol, which includes identification, screening, eligibility, and inclusion stages. The data analyzed consisted of 14 scientific articles obtained from databases such as Google Scholar, ERIC, ResearchGate, and Garuda, published between 2020 and 2026. The results indicate that the role-playing model consistently improves students’ understanding of science concepts through active, interactive, and contextual learning processes. In addition, this model contributes positively to students’ learning outcomes, motivation, and social skills, particularly in communication and collaboration. However, the effectiveness of this model is highly dependent on the quality of classroom implementation, student readiness, and the accuracy of lesson planning. Therefore, the role-playing model can be considered an effective instructional strategy in elementary science education, especially for explaining abstract concepts such as food chain processes.
