Batik coloring waste contains heavy metal chromium (Cr), and other components such as, Sulfide (S 2- ), Ammonia (NH 3 ), phenol and oil-fat. The Batik industries are generally classified as small and medium enterprises, which usually do not process their waste. The aim of this study was to observe the ability of  Aspergillus  sp. 3 to reduce the concentration of Cr, sulfide, ammonia, phenol, and oil-fat component from batik wastewater. The selected fungus,  Aspergillus  sp. 3 was isolated from batik waste. Based on previous study, selected fungus,  Aspergillus  sp. 3 was able to decolorize and remediate Indigosol Blue batik wastewater. Potato dextrose broth medium was used for growing the mycelium. Reduction process was occurred with omitted of medium (formed mycelium-supplemented the batik wastewater). Based on experiments,  Aspergillus  sp. 3 was able to reduce 89.09%, 83.05%, 56.37%, 48.48%, 95.09%, 32.56, 39.28 and 38.15% of Cr sulfide, NH3, phenol and total oil-fat concentration, respectively.  Aspergillus  sp. 3 had potential application in bioremediation of water polluted by batik wastewater.
