COMBINATION OF TREMBESI (Samanea saman) ADSORBENTS AND FITORMEDIATION OF KIAMBANG (Salvinia molesta) PLANTS TO REDUCE CHROME LEVELS IN BATIK WASTE

Chrome (Cr) is one of the harmful heavy metals whose existence could lead to a decline in water quality, as well harm environment and aquatic organisms. One industries that generate waste containing chrome batik industry. The resulting wastewater processing needs be done, which combine adsorbents trembesi seeds fitoremediasi plants Salvinia (Salvinia molesta). purpose this research know levels on process adsorbsi process. This was conducted with two processes, i.e. processes On use variations size mesh 30/40 60/70 and, after passing through then continues fitoremediasi. Treatment difference between living plants, IE 0-day, 2-day 4-day. Sampling done each process, carried out laboratory environmental engineering laboratory. Based results has been combination adsorbent molesta) capable lowering chromium batik. variation obtained result 8.771 mg/L 8.092 from figure control 10.563 mg/l. To day 0 8.730 mg/L, at 6.962 2 4th 6.212 Process adsorbent, 6.843 2nd 5.752 5.688 mg/L.
