Abstract

This study aims to identify and describe the ethnomathematical elements found in the bedug, a traditional musical instrument used by the community in Loura Subdistrict, Southwest Sumba Regency. The bedug not only functions as a musical instrument, but also has historical, philosophical, and visual value that reflects the cultural practices of the local community. This study uses a qualitative approach with a descriptive ethnographic research type. Data were collected through direct observation, interviews with traditional leaders and local communities, and documentation of the shape and structure of the bedug. The results show that the bedug contains various mathematical concepts, particularly the concept of spatial geometry, such as circles and cylinders, which are evident in the shape of the base and body of the bedug. These findings indicate that the Sumba community has intuitively applied mathematical principles in cultural practices and the creation of traditional artefacts. This study contributes to the development of ethnomathematics-based mathematics learning by integrating local wisdom, thereby making learning more contextual, relevant, and meaningful for students.

Abstract

Students' cognitive abilities in solving mathematics problems need to be studied to determine the level of concept mastery and thinking skills at each cognitive level, especially on the ratio material which is the basis for understanding various advanced mathematical concepts. This study aims to describe the cognitive abilities of class VII B students in solving mathematics problems on the ratio material. This study uses a qualitative approach with a descriptive method. The research subjects consisted of 12 class VII B students of SMP Negeri 1 Loura who were selected because they had studied the ratio material and represented the characteristics of students' abilities in mathematics learning in that class. The research instrument was in the form of six essay questions based on the Revised Bloom's Taxonomy indicators, namely C1 (remembering), C2 (understanding), C3 (applying), C4 (analyzing), C5 (evaluating), and C6 (creating). Data were collected through tests, observations, and documentation, then analyzed through the stages of data reduction, data presentation, and drawing conclusions. The results showed that students' cognitive abilities were in the high category, with 33.3% of students in the very high category, 50% in the high category, and 16.7% in the medium category. Students still struggle with higher-order thinking skills, particularly analyzing, evaluating, and creating. These findings suggest that mathematics instruction needs to be geared toward developing higher-order thinking skills through contextual problem-solving and learning strategies that encourage critical and creative thinking.
