Advancement Through Research
One form of handicraft from Lampung is a batik cloth called a filter cloth. Filter cloth in general. Ethnomathematics is a study that uses cultural symbols to bring up mathematical concepts. In this regard, filter cloth can be used for learning media in mathematics. Therefore, The purpose of this study is to explore ethnomathematics on Lampung tapis fabric motifs that can be used as a means of learning mathematics in geometry material. This research is classified as descriptive qualitative research with an ethnographic approach. The data obtained in this study were in the form of qualitative data, while the source of data was obtained from literature and documentation studies relating to the Lampung tapis fabric. The data validity technique is done by validity, then the data are analyzed descriptively qualitatively. The results showed that ethnomathematics in Lampung tapis fabric motifs can be identified from geometric motifs of filter cloth that contain mathematical concepts in the form of horizontal lines, parallel lines, triangles, hexagons, trapezoid, and geometric transformations. The concept of horizontal lines and parallel lines can be used for mathematical learning such as calculating the equation of lines, triangles, and hexagons are used to calculate area and circumference, and transformation of geometry to understand the concepts of rotation and reflection.
