Abstract

This paper shows efforts to popularize mathematics through batik culture in Indonesia. There are 2 classifications of batik used here, i.e. batik whose motif follows the symmetry of crystallography, and batik with motifs designed from algebraic surfaces called Batik Innovation of Mathematics (Batima). Crystallography motifs are made from 1 design as a motif and it can be generated into several motifs designed from one stamp batik. While the Batima motif is made from algebraic equations. This paper only shows a few examples of Batima with algebraic equations made in stamps batik. Some derivative products such as bags, masks, accessories, and key chains can also be made. In order for this batik to become part of the popularization of mathematics, promotional efforts are carried out using various existing promotional media. The promotion has been carried out since 2019 by creating blogs, exhibitions, and existing social media such as YouTube, web, shop marketplace, following competitions, and presenting at conferences. In 2023, the university has collaborated with a home industry called Nilo Tirto to develop varied motif designs and be produced on a limited scale. Furthermore, promotion and branding efforts for crystallographic batik and mathematical innovation batik products can be carried out in a sustainable manner.
