Eksplorasi Etnomatematika Kain Tenun pada Mayarakat Oeolo NTT untuk Mengungkapkan Konsep Matematis

: The purpose of this study was to describe the ethnomathematical form of the woven fabric of the Oeolo Village community located in North Central Timor Regency, East Nusa Tenggara Province. The type of research used is qualitative research with an ethnographic approach. Based on the results of ethnomathematical research on woven fabrics in the Oeolo Village community, it shows that there are several mathematical concepts in the process of making nap molo woven fabric motifs, namely: 1) the concept of counting which is carried out at the beginning of the weaver determines the number of spun yarns needed, according to the desired pattern of motifs. 2) measuring activity, weavers measure using the traditional unit of adult finger span to measure the length and width of the weave. 3) the comparison concept related to the number of yarn spun for the main pattern is more than the sandwich pattern. 4) point concept, on color thread pattern. 5) the concept of a straight line on the color thread used in the flanking pattern motif. 6) The concept of curved lines in the resulting middle motif. 7) the concept of a flat rhombus on the resulting motif.
