If so far the learning process has focused more on the teacher/lecturer (teacher center), a solution is needed to improve student understanding, one of which is by applying discovery learning learning techniques, where students can find their own formulas in learning & reasoning. Along with the desire to raise cultural values in the learning process, the ethnomathematical approach to learning is one of the best solutions to motivate students. This method is a collaborative discovery learning model with an ethnomathematical approach. namely the sasirangan cloth. After taking an ethnomathematical approach in the learning process, especially on topic of special groups, students are asked to provide an assessment of the learning process. The implementation of the Algebraic Structure learning course with an ethnomathematical approach has provided a significant increase in student abilities in terms of cognitive, affective and psychomotor. This is measured from student responses in learning questionnaires, evidence of completion of learning video assignments and the test results. Assessment for teaching lecturers also gave positive results from the pedagogical and professional side
