Abstract
The use of natural dyes for batik has some advantages because it produces a unique exotic color with exclusive imaging and is environmentally friendly due to the waste easily degraded. The purpose of this research was to obtain textile dye extract from brazilwood (Caesalpiniasappan L) and water guava (Syzygiumaqueum)leaves with various compotitions and fixer, i.e., alum, calcium carbonate and ferrous sulphate. The mordant used is alum and soda ash (Na2CO3). The highest color intensity (87.63%)was obtained from brazilwood/water guava leavesratio 50/50 and ferrous sulphate fixer, while the lowest (35.60%) from ratio 25/75 and calcium carbonate fixer. Keywords—Natural dyes, Caesalpiniasappan L, Syzygiumaqueum, fixer, color intensity
