Increased wastewater from the batik and textile industries as well as the content of chromium released from the coloring process will negatively affect an aquatic environment. The phytoremediation technique using Vetiver (Chrysopogon zizanioides L.) was applied to treat the wastewater. A hydroponic system with batik wastewater concentrations of 0%, 50%, 75%, and 100% was selected. Each treatment contained six pots, and each pot consisted of three clumps. This study aimed to determine the ability of Chrysopogon zizanioides L. to decrease chromium concentrations and improve water quality parameters (Ammonia, BOD, and COD) and analyze Chrysopogon zizanioides L. growth. On 50% wastewater composition, removal efficiency of chromium was 40%, BOD was 37.95±8.14 mg/L, removal efficiency of BOD was 98.47%, COD was 273.88±24.93 mg/L, and removal efficiency of COD was 89.05%. Relative growth rate (RGR) of plants was 0.002±0.00, and the number of living clumps was nine (50%). The results showed that 50% of batik wastewater can be treated by Chrysopogon zizanioides L. in a hydroponic system.
