Learning transformation geometry still faces challenges in visually understanding the concepts of translation, reflection, rotation, and dilation, as well as the suboptimal use of technology and local culture in mathematics learning. Therefore, the GEMBIRA (Interactive and Creative Culture-Based GeoGebra Mathematics) innovation was developed as a culture-based learning medium at SMAN 1 Kawali. The activity consisted of a preliminary study, media development, learning implementation, student response evaluation, innovation socialization, and teacher and student testimonials. The evaluation used a Google Forms questionnaire with a Likert scale. The results showed that the use of culture based GeoGebra increased student learning motivation, understanding of transformation concepts, creativity, and appreciation of local culture. The implementation of the GEMBIRA innovation has made a positive contribution to creating interactive, creative, and contextual mathematics learning.
