Abstract

One of the industrial activities in Indonesia is the tofu industry which uses soybeans and water as raw materials. If the tofu industrial wastewater is not treated and disposed of directly into the river, it can have a negative impact on the environment. Tofu industry liquid waste has BOD levels (Biochemical Oxygen Demand) high can cause health problems. One effort to reduce BOD levels in waters is phytoremediation. One of the plants used for the phytoremediation method is water hyacinth (Eichhornia crassipes). The purpose of this study was to determine BOD levels before and after phytoremediation. This research is descriptive research. The subject of this study was the BOD content of tofu industrial wastewater using water hyacinth remediation (Eichhornia crassipes). This study used variations of days, namely 7, 10, 13, 16, 19 with 2 replications and a volume of 15 L of wastewater. The results of the study were the BOD levels before treatment of 389 mg/l. Reduction of BOD levels of tofu industrial wastewater after water hyacinth (Eichhornia crassipes) phytoremediation on day 7 44.6%, day 10 49.9%, day 13 52.4%, day 16 57%, day 19 64%. The biggest decrease occurred on the 19th day and has met the requirements of Minister of Environment Regulation No. 15 of 2008. For the tofu industry concerned, this method can be used if there is no cost to build an WWTP. Meanwhile, for further research, it is possible to use waste taken from water bodies containing organic matter for the tofu industry.
