This research explored ethnomathematics activities on intangible cultural heritage unique to the Papuan people, especially the Malind Marori Anim (Marori Men-gey) indigenous people, namely Tifa or Kandala, a traditional musical instrument. This research adopted a qualitative approach with an ethnographic design using observation, interviews, and documentation. The results revealed the present study met the criteria for ethnomathematics activities: measurement, design, and explanation. Mathematical concepts that can be explored using this musical instrument include the calculation of surface area and volume, the application of congruence, and the use of integrals to determine the volume of solids of revolution. This is because the mathematical objects present in the Kandala consist primarily of cylindrical tubes and truncated cones. The findings suggest that this study could serve as an alternative approach for teachers to integrate ethnomathematics into their lessons, providing students with a unique and culturally relevant learning experience. © School of Engineering, Taylor's University.
