Abstract

The palm oil mill^s operational activities produce by products, one of the liquid waste that is odorous, colored, contains high COD, BOD and TSS values that have the potential to pollute the environment. The purpose of this study is to find out Eichhornia Crassipes can increase the pH value, reduce BOD, COD and TSS levels in Palm Oil Mill Liquid Waste so that they meet quality standards. This study consisted of three stages, namely the phytoremediation process using Eichhornia crassipes, then BOD and COD testing was carried out resulting in a decrease in BOD to 30.27 mg / L on day 21 and COD of 172.95 mg / L on day 21, then TSS and pH testing produced TSS of 9.00 mg / L on day 21 and a decrease in pH up to 7.82.

Keywords: Palm Oil, Eichhornia Crassipes, BOD, COD, pH, TSS.
