ABSTRAK

Indonesia has a variety of cultures, one of which is Pagatan woven fabric. Pagatan woven fabrics with various motifs are a form of cultural linkage with mathematics. Ethnomathematics is a science of connecting mathematics and culture which will be more easily accepted and understood by students and will increase their interest in learning. The type of research used is field research where researchers go directly to the field using qualitative approaches and ethnographic methods. Methods of data collection using interviews, observation and documentation. The owner and employee of Pagatan Weaving Salmah became the subject of research, while the objects of research were the motifs of woven fabrics and the fundamental mathematical activities according to Bishop in the process of making Pagatan woven fabrics. The data analysis technique used in this study went through three stages, namely data reduction, data presentation, and drawing conclusions. The results showed that there were 21 typical motifs of Pagatan woven fabrics found in the Salmah Pagatan Weaving industry. In these motifs there are mathematical concepts, such as straight lines, curved lines, curves, parallel lines, intersecting lines, angles, triangles, rhombuses, circles, squares, similarity and congruence, folding and rotation symmetry, mirroring, displacement, and number patterns. In addition, also found fundamental mathematical activities according to Bishop in the process of making Pagatan woven fabrics, namely counting, finding, measuring, designing, playing and explaining. Keywords : Ethnomathematics, Pagatan Woven Fabric, Mathematical Fundamental Activities.
