Post utilization of eceng gondok and ketapang leaf extract to reduce phosphate levels in domestic waste

Abstract

Abstract Utilization of enceng gondok ( Eichornia crassipes ) and ketapang ( Terminalia catappa ) was to reduce phosphate levels in domestic waste. This study aims to determine the effectiveness of the combination of E. crassipes and T. cattapa leaf extract in reducing phosphate levels in household wastewater and determine the optimal time that can be generated of the use of a combination of E. crassipes and T. cattapa leaf extract. The approach of this research is an experimental study that aims to treat domestic phosphate-containing wastewater, using small-scale wastewater installations with a simple process for the treatment of waste produced from households. The results of this study showed that the combination of E. crassipes and T. cattapa leaf extract effectively had a significant effect in reducing the value of phosphate content in the wastewater. While the optimal residence time in this study was obtained, a decrease in phosphate levels using a combination of E. crassipes and T. cattapa leaf extract occurred on the 18th day.
