Fractal geometry is a branch of mathematics that studies the properties and behavior of fractals. A fractal is a shape that has a repeating pattern. This pattern has infinite detail which when enlarged can have a structure similar to the fractal itself. Many fractals are generated by recursively repeating patterns. This study aims to describe the fractal geometry contained in the motif of the buna panbuat woven fabric of the Amanuban tribe, South Central Timor district. This type of research is qualitative research with ethnographic methods. Collecting data in the study using observation, interview, and documentation techniques. The method used to calculate the fractal dimensions of the buna panbuat woven fabric motif is box-counting assisted by Matlab. The results showed that one of the applications of mathematical principles on the motif of buna panbuat woven fabric is the principle of fractal geometry, namely the principle of recursiveness. The fractal dimension of the buna panbuat woven fabric motif is 1.9, which means that the roughness and detail of the motif are high. This shows that in the practice of weaving, the Amanuban tribe has applied mathematical concepts in creating motifs on woven fabrics.
