Book excerpt: Batik is one of the wealth of the Indonesian people as an invaluable cultural heritage. Indonesian batik has been known to foreign countries and become a superior export product. Every region in Indonesia has batik products with their own peculiarities. Efforts to overcome the boredom of batik products are done through the development of motifs, techniques, and textile used. One of the developments of batik products is through exploration of the use of soil as natural dyes of batik. This exploration is a research activity carried out by researchers and teams for 3 years. The result obtained is the discovery of soil as a batik dye which is explored with a variety of techniques named by researchers with soil batik.
