Abstract
Floating wetlands on a container (25Â L) using Vetiveria zizanioides (L) Nash was applied to remediate crude oil spill in water for four weeks. Three plants (height 10Â cm) were inserted in a pot containing rockwool, floated on crude oil spiked water. Treatment included 3 and 6 pot plants with 1% crude oil concentration. Six pot plants during 4Â weeks of experiment could reduce the oil content of 91.39%, 84.60% COD, and 84.25% BOD. Meanwhile, 3 pot plants could decrease the oil content of 90.28%, 81.69% COD, and 81.10% BOD. DO at week 4 decreased. The BOD and COD did not show any significant reduction. Plants grew better in crude oil contaminated water. Those were indicated by 47.22% parent and 100% shoots could live until the study end in 1% crude oil spiked water. Meanwhile, in crude oil uncontaminated water, 30.56% parent and 40% shoots were able to live until the study end. Wet plant biomass (5.1070Â g) in the crude oil contaminated water was greater than the plant biomass (4.8362Â g) in crude oil uncontaminated water. RGR of V. zizanioides in crude oil contaminated water was 5.10Â g/week and 4.83Â g/week in uncontaminated water.
