Exploration of Ethnomatematics in Traditional Agricultural Tools in Kubu Raya Regency

The abstract nature of mathematics poses a unique challenge for teachers in explaining mathematical concepts to students. In fact, many mathematical elements exist in everyday life that can be used as teaching aids for mathematics, one of which is the agricultural tools used by farmers in Kubu Raya Regency. Therefore, it is important to conduct research. This study aims to describe (1) traditional agricultural tools in Kubu Raya District and (2) mathematical concepts in the form of traditional agricultural tools in Kubu Raya District, West Kalimantan. This study employs a qualitative descriptive research method with an ethnographic approach. Data collection was conducted through interviews and documentation, with a total of three farmers in Kubu Raya District who are active users of traditional rice farming tools as research subjects. The results of the study indicate that: (1) The agricultural tools used by farmers include ani-ani, bakul, tampah, lumpang, and tongkat (alu), (2) The mathematical concepts found in traditional agricultural tools in Kubu Raya District include geometric two-dimensional shapes and three-dimensional shapes, as well as measurement concepts such as perimeter, area, and volume. From the results of this study, it is hoped that teachers can gain insights into developing contextual and culture-based mathematics materials, so that students can understand that mathematics is closely related to life and easy to learn.
