Effect Addition Of Coconut Fiberon Effectiveness Chromium(Cr)Phytoremediation In Tannery Solid Waste Using Alocasiamacrorrhiza

Leather industry is using chromium for tanning process. Solid waste from this process directly are dumped to land.
This waste is hazaroudus to enviromentThe aims of this study is toinvestigate addition of coconut fiber on solid tannery waste
to effectiveness chromium phytoremediation using Alocasiamacrorrhiza. Coconut fiber used is 75 g (A1), and 150 g (A2), while
biomass of Alocasiamacrorrhiza used is 200 g (B1), and 400 g (B2). This study was conducted for 15 days. Parameters measured
are total chromiumin solid waste, total chromium in fiber coconut,total chromium in plant, total chlorophyll, and
plants.biomass. Result showed, the addition of coconut fiber in the tannery solid waste does not affect the effectiveness of
chromium phytoremediation. However, the plants treated with the addition of fiber coconut can survive longer than the plants
without addition of coconut fiber (control). The largest effectiveness in total chromium which occur in the control is 40.36%.
