Cr(VI) and dye contents on batik wastewater has been reduced by biosorption using cheap, abundant, and easily obtained biosorbent such as Sargassum cinereum and Pleurotus ostreotus baglog waste. Biosorbent in the tea bags can increase adsorption capacity because it has a large surface.This research aims to obtain the optimum of biosorbent ratio and particle size in the tea bag package to Cr(VI) adsorption and decolorization. This experimental research was conducted using Spilt Plot Design. The obtained data were analyzed using anova test on 5% significane level. Based on result study, the highest of Cr(VI) adsorption found at the biosorbent in the tea bag with ratio of 3:1 and particle size of 250-425 urn i.e. 0,0042 mgg-1 with reduction efficiency was 68,31%. Percentage of decolorization was 39,92% found at biosorbent in the tea bag with ratio 0:1 and particle size of 425-675 urn. Biosorbent in the tea bag was effective to reducing Cr(VI) and dye in batik wastewater.
