Abstract

This study aims to develop a comic media application of the System of Linear Equations in Three Variables, test the validity and practicality of the System of Linear Equations in Three Variables comic media application for class X students of SMKN 3 Yogyakarta. This research uses the Research and Development (R&D) research method with the ADDIE (Analyze, Design, Development, Implementation and Evaluation) type of development model. Data collection techniques with observation, questionnaires and interviews. Data analysis techniques use analysis of the validity and practicality of comic media. The research involved 5 students for small class trials, and 30 students for large class trials The results of the development in the form of media in the form of System of Linear Equations in Three Variables comic media applications. The results of the study obtained an average score of validity of material experts 59 and media experts 76.5 with “Good” criteria. Practicality test with the results of the average score of practicality of small class trials 68.5 and large class trials 65.72 with “Good” criteria. This shows that the System of Linear Equations in Three Variables comic media application meets the valid and practical criteria so that it is considered as an alternative to be used in learning mathematics.

Abstract

This Community Service Program (PkM) aims to improve the numeracy literacy skills of students at SD Negeri 1 Pedes through intensive tutoring at the UMBY Mathematics Education Tutoring Center "The Brilliant Minds". This activity was conducted from June to July 2026, targeting 3rd grade students. The program was implemented through an academic collaboration between Mathematics Education lecturers from Universitas Mercu Buana Yogyakarta (UMBY), Mathematics Education lecturers from Universitas Ahmad Dahlan (UAD), and students from the UMBY Mathematics Education Student Association (HIMATIKA). The implementation method was based on a need assessment and a participatory approach comprising five stages: preparation, diagnostic assessment, module/tool development, intensive tutoring, and evaluation and follow-up. One of the main innovations applied by student tutors was the use of the Jarimatika method and context-based word problems to reduce math anxiety and enhance students' concrete understanding. The evaluation results showed an increase in the overall average numeracy score, from a pretest score of 93.45 to a posttest score of 95.00. The most significant improvement was experienced by students in the category requiring intensive guidance. This program proved effective in building students' motivation, confidence, and critical thinking skills, while providing a sustainable impact through the handover of learning modules to the partner school.
