Abstract

This study aims to determine the mathematical elements contained in the weaving ikat Bajawa community. In this research will also be discussed about the meaning of weaving motif weaving ikat Bajawa society. For that researchers use qualitative methods with data collection techniques in the form of interviews, documentation, and literature study. Interviews were conducted in the form of unstructured interviews, and the resource persons were weavers and customary figures. In this study, researchers will relate mathematics with motives, tools and materials as well as the economic value of the manufacture of ikat community Bajawa. The stages in this research is the stage of data collection and data analysis phase. Data analysis phase in this research are: data reduction, data display (data exposure), conclusion and verification. The analysis is done by conducting a comprehensive collection of observations ranging from descriptions, manufacturing techniques, the meaning of decorative motifs and weaving functions in Bajawa society as well as analysis in the search for differences and weaving equations. The results showed that Bajawa community bonding elements contain mathematical elements such as measurements, straight lines, and geometry seen from the similarity of ikat weaving motifs with random and rectangular triangles. Woven tools and materials have similarities with a flat wake and wake up space. There is also an element of arithmetic in the sale of ikat woven fabrics, where the price of one weave ranges from Rp500,000 – Rp600.000 to obtain benefits in accordance with expenditures and manufacturing processes.
