Abstract

This study aims to analyze the application of single interest and compound interest in savings and loan cooperatives. Interest is an important aspect of savings and loan cooperative operations that can affect cooperative finances and member satisfaction. In this study, an analysis was carried out on the differences between the application of single interest and compound interest and their impact on savings and loan cooperatives. The research method used is literature study and comparative analysis. Data were obtained from primary and secondary sources which included cooperative documents, related literature, and interviews with cooperative management. The results of the study show that the application of single interest and compound interest has different implications for cooperative finance and member satisfaction. The conclusion of this study is the importance of savings and loan cooperatives considering factors such as the characteristics of the members, the goals of the cooperative, and the clarity of calculations in choosing the type of interest to be applied. Education to members about the difference between single interest and compound interest and their implications is also an important factor in the successful application of interest in savings and loan cooperatives.

Abstract

The branch of mathematics that studies history is usually known as ethnomathematics, and the concept of ethnomathematics has made a major contribution to improving mathematics learning. It turns out that many cultures cannot be separated from mathematical calculations, including historical buildings that are simple but have many meanings and meanings. So this research was conducted to describe and identify mathematical concepts in Betawi Warehouses in the Setu Babakan Betawi Cultural Village. The research method used is a descriptive qualitative method with an ethnographic approach. The results of the research show that there is a mathematical concept in the Gudang Betawi house building in the Setu Babakan Betawi Cultural Village, namely the shape of the Gudang Betawi house which has a rectangular pattern from front to back, there are many philosophies in ornaments that have sizes and shapes, and there are geometric elements found in the building. Betawi Warehouse Houses are like whole numbers in measuring activities, equivalent comparisons in calculating the length of time to build a Warehouse House, there are corners in the building, there are flat geometric elements found in the length, area and perimeter of the building, there is also space geometry which has content and volume , there is a geometric transformation in the ornamental part of the Gudang Betawi house, and there is a congruence of flat shapes that can be seen on the door of the Gudang Betawi house.

Abstract

Ethnomathematics contributes greatly to the improvement of mathematics learning, because it relates to students' experiences in everyday life that touches the realm of local cultural arts so that students become more understanding of the mathematical concepts explained. This study aims to explore the concept of mathematics in the traditional game of congklak in Srengseng Sawah Village. This research is a qualitative research with an ethnographic approach. The data collection techniques used are observation, interview and documentation. The instruments in this study were researchers, observation guidelines, interview guidelines and documentation. Based on the research analysis and discussion of the history and philosophy of the traditional game of congklak, mathematical concepts in the game of congklak such as the concept of flat shapes, namely semicircles, circles, rectangles and spatial shapes, namely half a ball; the concept of transformation in this case reflection / mirroring; the concept of arithmetic calculation operations including addition, subtraction, multiplication and division. The game also has cultural and philosophical values.
