Ethnomathematic Exploration Of Selling and Buying Activities In The Keramat Pacet Market

Introduction

Ethnomathematic exploration of selling and buying activities in the keramat pacet market. Explore ethnomathematics in buying and selling activities at Keramat Pacet Market. Discover how concepts like counting, profit, arithmetic operations, and sets are used in daily transactions.

Abstract

This research aims to describe ethnomathematics at Pasar Keramat, Pacet. This research includes qualitative research. The data collection techniques used in this research were interviews and documentation. The data analysis technique used is the Miles and Huberman method, which consists of several stages, namely data collection, data reduction, data presentation, and drawing conclusions. The data obtained is in the form of interviews, documentation and observations. Then the data is classified and simplified to focus on relevant elements. The reduced data is presented in a table containing the type of activity, documentation, mathematical concepts used, and activity descriptions. The research results show that mathematical concepts are used in buying and selling activities at Keramat Market, Pacet. The mathematical concepts used are the concept of counting in money exchange activities, the concept of profit and arithmetic operations such as: addition, subtraction and multiplication in pricing activities and buying and selling transactions, and the concept of sets in packaging activities.

Review

This paper presents a focused ethnomathematical exploration within the vibrant setting of Pasar Keramat, Pacet, aiming to describe the mathematical concepts embedded in local selling and buying activities. The research employs a fitting qualitative methodology, leveraging interviews and documentation for data collection, and utilizes the well-regarded Miles and Huberman method for data analysis. This systematic approach, involving data collection, reduction, presentation, and conclusion drawing, ensures a structured investigation into the presence of mathematics in everyday market transactions. The clear articulation of the research aim and the chosen methods provides a strong foundation for an insightful study into culturally specific mathematical practices. The findings successfully identify several fundamental mathematical concepts actively used by market participants. The abstract highlights the application of counting in money exchange, the crucial concept of profit alongside basic arithmetic operations—addition, subtraction, and multiplication—in pricing and transaction processes, and even the concept of sets in the seemingly simple act of packaging goods. These results offer concrete empirical evidence for the existence and practical application of ethnomathematics in a real-world, localized economic context. The proposed method of presenting reduced data in a table, correlating activities with concepts and descriptions, suggests a systematic and accessible way to illustrate the findings, thereby enhancing the clarity and impact of the research. While the abstract provides a compelling overview, a full paper would benefit from deeper elaboration on several fronts. It would be valuable to explore the *cultural nuances* of these mathematical practices, perhaps comparing them with formal school mathematics or discussing how they are learned and transmitted within the market community, rather than solely identifying their presence. Further discussion on the *pedagogical implications*—how this localized ethnomathematical knowledge could inform or enrich formal education—would significantly enhance the study's broader impact. Additionally, considering the specific context of Pasar Keramat, Pacet, a discussion on the generalizability of these findings or a reflection on potential limitations due to its unique cultural setting would strengthen the overall contribution and critical understanding of the research.
