Abstract:	This study aimed for treating wastewater batik using pellet and determine the effect of pellet in Cr content and COD. This experimentswere done with a combination of pellet concentration (%w/v) in the wastewaterbatik, whichwere0:10 (% w/v), 5:10 (%w/v), 10:10 (%w/v), 15:10 (%w/v), and 20:10 (%w/v) within a retention time of seven days. Each treatment usedthree replications. The resultsshowed that there wereadecrease in each variation of pellet addition. Obtained optimum decrease in treatment 0:10 (%w/v) and 10:10 (%w/v) with Cr content value are -0.0419 mg/l. COD decreased optimum at 0:10 treatment (%w/v) reached 80.07% with a value is 386.76 mg/l.
