Abstract

Geometry Ability is one of the mathematical abilities that must be mastered by students, this is because geometry ability is one part of learning mathematics. However, the reality in the field in junior high school students, students have difficulty in learning transformation geometry, namely in the material of reflection, rotation, translation and dilatation. This difficulty of students is caused by students not understanding the coordinate points on the cartesian plane. The difficulty of students in determining cartesian coordinates has the effect that students cannot determine straight-line drawings based on straight-line equations. Another thing that causes students difficulty in understanding the geometry of transformation is that students' ability to think abstractly is still very low, students cannot describe concepts from mirroring, turnover, shifting and dilatation. The purpose of this study is to understand the geometry of trasnsformas through the exploration of Jambi batik. The research method used is descriptive qualitative, the result of the research obtained is that there is a concept of transformation geometry in Batik Motik Jambi so that it can be applied in mathematics learning

Abstract

Ethnomathematics can be an option for teaching a more contextual mathematics which contributes to a successful mathematics learning. The present study highlighted ethnomathematics concepts that could be found in Sumedang’s local food, namely Sumedang Tofu, and the bamboo basket used as its container (bongsang).  Mathematical concepts in Sumedang Tofu and its bongsang are related to geometry. Geometry allows students to develop their abilities in presenting or describing the order in the world or their immediate environment. Geometry learning affects students’ ability to connect mathematical ideas, both in the discipline and to other disciplines as well as the real world. The results of this study show that Primary School students still had difficulties in learning and understanding geometry. Therefore, it was necessary to develop a method that would improve students’ understanding of geometrical concepts, which were important because they were highly relevant to students’ daily life. The present study aimed to explore geometrical concepts found in Sumedang tofu and bongsang. Descriptive qualitative approach was implemented, in which the data was gathered through observation, literature study, and interviews. The findings indicated that geometrical concepts could be found in Sumedang tofu and bongsang. Those concepts could be used in mathematics lessons in primary school to provide meaningful learning for students. The results of this study could be used as a foundation to develop an ethnomathematics learning in primary school level.
