Abstract:
This study aims to measure the growth of macrohydrophita plants, to determine the ability of macrohydrophita plants in improving the quality of plywood wastewater industry and compare with the quality standard and to know the best treatment in phytoremediation process of plywood liquid waste. This research was conducted at Greenhouse Hall of Food Crop Protection and Horticulture, from June to October 2017. This research use Completely Randomized Design with 6 treatments repeated 3 times. The treatment used consisted of T0L1Tn0 (wastewater without wetlands and without crops), T1L1Tn0 (wetland without crops), T1L1V1 (wetland using Akar Wangi plant (Vetieria zizanioides L.)), T1L1A1 (wetlands using Jeringau plant (Acorus calamus L.)), T1L1N1 (wetlands using Iris plants (Neomarica longifolia)), T1L1P1 (wetlands using polyculture crops). After phytoremediation during the 35 day stay period, the highest percentage of biomass in T1L1N1 (60.54%). Percent improvement of quality of plywood liquid waste after phytoremediation process of highest pH improvement on T1L1N1 treatment (10,19%), TSS at T1L1Tn0 treatment (87,05%), BOD at T1L1P1 treatment (57,18%), COD also on T1L1P1 treatment (72.01%), and NH3 on T1L1V1 treatment (-82471,05%). But not been able to meet the quality standards of plywood wastewater set at South Kalimantan Governor Regulation No. 36 Year 2008. Calculated from the pollution index, the best treatment in wetland treatment using the Akar Wangi plant (V. zizanioides L.) with the pollution index value of 9.36 was classified as medium polluted
