Abstract

Batik is the art work of the Indonesian people which is a cultural heritage from their ancestors which has become one of the world's recognized cultural heritages. Batik itself has a variety of patterns that are influenced by the customs of the local community and contains deep meaning and philosophy. Endemic flora and fauna are often used as patterns for batik motifs. In the process of forming batik motifs, mathematical knowledge is often required which sometimes appears naturally. Mathematics that is closely related to culture is called ethnomathematics as a branch of mathematics. Ethnomathematics can be used in forming batik patterns, especially fractal forms. A fractal shape is an object that appears to have a symmetric self-resemblance to one another when viewed at a certain scale and is the smallest part of the overall structure of the object. The purpose of this research is to make fractals of local batik motifs from Central Sulawesi using the endemic plant of Bunga Katimong (Etlingera Elatior) with the help of the j-Batik application so that new motifs are obtained to add to the diversity of existing batik motifs. The new batik motifs produced in this research are Katimong, Kantan, Kincung and Honje.

Abstract

This activity aims to provide an understanding of business development based on marketing strategies. Marketing strategy is a crucial aspect for Moringa Popcorn and Moringa Stick producers to achieve business goals, especially in the face of competition. Business development requires the implementation of a marketing mix encompassing Product, Price, Promotion, and Place/Distribution. These four elements play a role in directing marketing activities to be more effective and increase product competitiveness. This community service activity was conducted at SMAN 20 South Konawe, Southeast Sulawesi Province, over two months through outreach and workshops. Participants included 25 teachers and students, supported by 7 university students and 10 lecturers from the Faculty of Economics and Business. The methods used included participatory learning, mentoring, and hands-on practice. Evaluation results showed a positive response from participants. They considered the marketing strategy material, covering product, price, distribution, and promotion, very useful and able to increase motivation in developing the business and supporting family economic growth.

Abstract

This study investigates the representational transition patterns of pre-service teachers in solving convergent-sequence problems, with a focus on how they utilize symbolic, visual, and verbal representations. Using a qualitative phenomenological design, seven pre-service mathematics teachers were purposively selected based on their dominant representation modes (symbolic, visual, verbal). Participants solved a convergent-sequence task, and their problem-solving processes were analyzed using a modified Colaizzi method, with triangulation ensuring the validity of the findings. Three key patterns emerged: a stagnant reliance on a single representation mode (symbolic or verbal), a linear transition from visual to symbolic forms, and a complementary use of symbolic and verbal representations. No cyclic or complex transition patterns were identified, indicating limited representational fluency. The findings highlight the dominance of symbolic representations among pre-service teachers, with some exhibiting limited representational flexibility. The study suggests that fostering representational fluency, where students can effectively transition between different forms, is crucial for deeper conceptual understanding, especially in abstract topics like convergent sequences. Pedagogically, the study underscores the importance of instructional strategies that encourage the integration and transition across symbolic, visual, and verbal representations. This research contributes to the understanding of representational transition patterns in real analysis, an area often underexplored in mathematics education, and offers insights for improving teacher preparation programs.

Abstract

Purpose: This study aims to develop an open-ended diagnostic test to identify pre-service mathematics teachers’ Dominant Mathematical Representations (DMR) in Real Analysis, with a specific focus on convergent sequences. Method: A Research and Development (R&D) approach was employed using Plomp’s development model, which includes preliminary research, prototyping, and assessment phases. The diagnostic instrument was constructed based on representational theory and consisted of six open-ended tasks designed to elicit representational choice, integration, and transferability. Content validity and linguistic clarity were evaluated by two mathematics education experts and one language expert. A limited field trial involving 19 pre-service mathematics teachers was conducted to examine the instrument’s validity and practicality. Data were collected through the diagnostic test, expert validation sheets, and a student response questionnaire, and analyzed descriptively using qualitative feedback and quantitative percentage-based indicators. Findings: The results indicate that the developed diagnostic test demonstrates strong content validity, with a mean validity score of 85.4%, classified as very valid. The practicality evaluation yielded a mean score of 83.7%, indicating that the instrument is very practical in terms of clarity, format, language, and time allocation. Expert review confirmed alignment between the test items and the DMR construct, while student responses indicated feasibility and comprehensibility. Significance: This study contributes to mathematics education assessment by operationalizing Dominant Mathematical Representations as an explicitly assessable construct through open-ended diagnostic tasks, providing a foundation for representation-sensitive instruction in Real Analysis.

Abstract

This study aimed to explore the characteristics of students’ mathematical problem-solving strategies in Problem-Based Learning through Polya’s stages in solving compound interest problems. This study employed a qualitative descriptive case study. The participants consisted of 35 Grade XI students at SMA Negeri 2 Tolitoli, Central Sulawesi. Data were collected through problem-solving tests, interviews, observations, and documentation. Three representative students from high-, moderate-, and low-level problem-solving characteristic profiles were selected purposively for in-depth analysis. Data were analyzed using Miles and Huberman’s interactive model. The findings showed that students demonstrated different strategy characteristics across Polya’s stages. At the understanding stage, students demonstrated complete identification, partial understanding, and misunderstanding strategies. During the planning stage, conceptual, procedural, and trial-and-error strategies emerged. At the implementation stage, students demonstrated systematic solution, procedural error, and inconsistent-step strategies, while at the reflective stage, students showed solution evaluation, partial verification, and no verification strategies. Students with high-level profiles tended to demonstrate coherent and interconnected strategy patterns, whereas students with low-level profiles demonstrated fragmented and inconsistent processes. The findings further indicated that students’ strategies developed as interconnected processes in which difficulties emerging at earlier stages influenced subsequent stages. Reflective activities were identified as the weakest component of students’ mathematical problem-solving processes. The findings contribute theoretically to understanding how students’ mathematical problem-solving strategies emerge and develop across Polya’s stages within Problem-Based Learning environments. Practically, the findings highlight the importance of strengthening reflective activities and supporting interconnected strategic thinking in mathematics learning
