Abstract

The tofu industry produces waste in its processing process in the form of solid and liquid waste. One alternative to liquid waste treatment that can be used is the phytoremediation method. Phytoremediation system is a wastewater treatment technique using aquatic plants to help reduce organic substances contained in wastewater. This study aims to determine the effectiveness of water spinach (Ipomoea aquatica) in reducing heavy metal levels in tofu factory wastewater. This research method is experimental research on tofu factory wastewater with the research design used is pretest-posttest with control group. Based on the research obtained water spinach (Ipomoea aquatica) effective in reducing heavy metal levels in tofu liquid waste is evident from the lower TDS levels shown in the treatment using water spinach plants (Ipomoea aquatica) with a concentration of 25% of 1,503 ppm with the length of time required for 6 days.

Abstract

Water pollution by detergent waste is a serious environmental problem because it contains chemical compounds such as phosphates and surfactants that are difficult to decompose. The Pistia stratiotes (kiambang) plant is a water weed that pools on the surface and is often used as an aquarium filler or as an interior ornament for water ponds. The benefits of aquatic plants such as kiambang can reduce the concentration of pollutants in waste through the phytoremediation process. This research aims to determine the ability of the kiambang plant (Pistia stratiotes) as a phytoremediation agent in reducing the level of water pollution and improving the quality of water exposed to detergent waste. The research method used was experimentation with variations in kiambang mass (50 g, 100 g, 150 g) in detergent wastewater samples. The research results show that the greater the mass of kiambang plants, the more effective it is in reducing water pH and improving water quality. The largest decrease in pH occurred in the treatment with a kiambang mass of 150 g after seven days, reaching an average pH value of 7.78. Phytoremediation with kiambang has been proven to be an environmentally friendly solution for managing detergent waste and helping restore aquatic ecosystems.
