Development of a Deep Mathematics DEMA Model of Sequences and Series Based on North Kalimantan Batik for Class X DKV SMK Negeri 4 Tarakan

The low relevance of mathematics teaching materials to the vocational context and local culture hampers learning in Vocational High Schools majoring in Visual Communication Design. This study aims to develop a Deep of Math learning module based on ethnomathematics of North Kalimantan batik motifs using the Analyze, Design, Develop, Implement, and Evaluate development model. The research and development method applies expert validation sheets and user response questionnaires on a Likert scale of 1–4, with quantitative and qualitative descriptive analysis. Expert validation resulted in a score of 75% for materials and 66% for media, with an average of 71% (feasible category). Implementation was limited to 15 students and 2 teachers, obtaining a response of 79.83% from students and 71.25% from teachers, with an average practicality of 75.54% (practical category). The module increases the relevance of arithmetic and geometric sequences through Dayak batik motifs. The Deep of Math module is feasible and practical as an independent teaching material, although it requires strengthening of high-level analysis.
