Phytoremediation of Detergent Levels in Waters Using Water Plants: Eichornia crassipes, Ipomoea aquatica, Pistia stratoites and Their Combinations

Research on phytoremidiation to reduce detergent waste in waters has been successfully carried out. The phytoremidiation process is carried out using aquatic plants: Eichornia crassipes, Ipomoea aquatica, Pistia stratoites, and their combinations. The treated water sample comes from the Ancar river Mataram, NTB. The research is experimental with a randomized block design, with the procedure: Water samples are planted with aquatic plants according to the research design which serves to absorb detergent waste. Detergent levels before and after the treatment of aquatic plants were observed using the MBAS (Methylen Blue Active Substance) method. The results showed that the three water plants used were able to reduce the concentration of detergents and improve the concentration of water quality parameters (pH, DO, BOD, and COD) and which had the best ability (73.60%) in absorbing detergents was a combination of Eichornia crassipes and Ipomoea aquatic the best accumulation time of absorption occurred in the period of 7 to 14.
