Ethnomathematics Exploration of Fish Trader Activities in The Traditional Market of Punggulan Village, Asahan Regency

Abstract

This study aims to explore the activities of fish traders in traditional markets by connecting mathematics and culture, known as ethnomathematics. The type of research used is qualitative research with an ethnographic approach. Data collection techniques used are library data, observation, and interviews. The data analysis technique refers to the Miles and Huberman model: data reduction, data presentation, and conclusion. This study found that the activities of fish traders in traditional markets were grouped into three processes: measurement, packaging, and buying and selling. The concepts found in these three activities are measurement, sets, one-variable linear equations, weight comparisons, social arithmetic, relations and functions, two-variable linear equations, flat-sided spaces, and probability. Thus, the activities of fish traders contain ethnomathematics elements which are simultaneously an application of mathematical theory learned at school. Further researchers are advised to examine the quality of ethnomathematics-based mathematics learning.
