Frieze Group in Generating Traditional Cloth Motifs of the East Nusa Tenggara Province

Ethnomathematics studies the relationship between mathematics and culture. Indonesia has many traditional cultures. One of them is cloth. The cloth from East Nusa Tenggara (NTT) province called tenun ikat. Since motif ikat consists symmetrical repeated patterns, it can be generated using Frieze groups. groups are plane symmetry patterns whose subgroups translations isomorphic to Z. There seven in groups, i.e., F_1, F_2, F_3, F_4, F_5, F_6, F_7. Translation, reflection, rotation, glide reflection transformation used In this paper, generate digital motifs basic pattern. one piece original may consist some identified first, then each into desired pattern, according suitable Furthermore, a GUI Matlab program developed Three presented demonstrate implementation With group, users other so new without leaving cultural characteristics NTT province.
