transactions can serve as a medium for learning mathematics. The method used in this study is a qualitative approach with an ethnographic perspective, allowing the researcher to observe and understand phenomena within a broader social context. Data collection was carried out through interviews with traders and market visitors, direct observation of the coin exchange activities, and documentation of activities related to these transactions. The collected data were then analyzed using three main stages: data reduction, data presentation, and conclusion drawing. The results of the study show that the practice of coin exchange not only facilitates transactions in the market but also serves as a medium for applying arithmetic operations in everyday life. This activity encourages the development of logical thinking skills, such as addition, subtraction, multiplication, and division, which are frequently used in the bargaining process or in determining the price of goods. Furthermore, coin exchange helps maintain price stability and increases transaction efficiency in the market by reducing dependence on paper money, which is often difficult to divide accurately. Thus, the study concludes that the application of ethnomathematics in coin exchange activities at Sarwono Market provides dual benefits, both in the economic context and in mathematics education.

ll-being of shareholders and attracts investors’ interest. Corporate value is often gauged by the stock price in the capital market, making it crucial for companies to plan sound financial strategies. This research focuses on the banking sector listed on the Indonesia Stock Exchange (IDX) from 2021 to 2023, evaluating the influence of investment policy, dividend policy, and profitability on corporate value. The study employs a descriptive quantitative method using secondary data from the companies’ financial reports. Multiple linear regression analysis is used to assess the relationships between these variables. The results indicate that investment policy and profitability have a positive but not significant effect on corporate value, while dividend policy has a significant positive impact. Corporate value is also affected by stock price fluctuations, which are often inconsistent. These findings affirm that dividend policy is a crucial factor in enhancing corporate value, while investment policy and profitability, although important, do not have a significant impact within the study period. Overall, these independent variables collectively have a significant influence on corporate value in the banking sector on the IDX. This research provides insights for company management in formulating effective strategies to increase corporate value.
