<![CDATA[This study aims to develop and test the effectiveness of a digital comic integrating tetrahedral representations (human, microscopic, macroscopic, and symbolic) and ethnochemistry within the context of Sasirangan fabric dyeing. A convergent parallel mixed-methods design was employed, involving students from SMA Negeri 4 and SMA Negeri 12 Banjarmasin. Data collection utilized validation questionnaires for content and media experts, student response questionnaires, tests for conceptual understanding and misconceptions, and an ethnochemistry literacy questionnaire. Effectiveness was assessed using a non-equivalent pretest-posttest design with a control group, involving 120 students divided into control and experimental groups. Validity results from media and content experts indicated that the developed digital comic was highly valid, while student responses demonstrated high practicality with a positive reception. Effectiveness testing revealed that the digital comic improved conceptual understanding and reduced misconceptions in the experimental group compared to the control group. The Mann-Whitney U test results indicated a significant difference between the groups. Overall, the findings suggest that the proposed ethnochemistry-integrated tetrahedral digital comic is valid, practical, and effective for culture-based chemistry learning on colloidal materials.]]>
