Abstract

Eco-enzyme represents a biological solution derived from the fermentation of organic materials, evaluated for its effectiveness in industrial wastewater treatment. This study examines  to investigate the effectiveness of eco-enzymes in improving the quality of industrial wastewater by analyzing their impact on four specific types of liquid waste: landfill leachate, tofu wastewater, batik wastewater, and laundry wastewater. Samples were treated with eco-enzyme at specific concentrations and incubated for 5 days, followed by chemical analysis. Eco-enzyme reduced ammonia levels in landfill leachate by 57% to 8.83 mg/L, though COD and BOD values rose to 18,114.6 mg/L and 46,709 mg/L, respectively, exceeding effluent standards. In tofu wastewater, COD and BOD decreased by 72% and 75% to 4,189.68 mg/L and 2,395.3 mg/L, respectively, but remained above regulatory limits. Batik wastewater showed increases in most parameters, with COD and BOD reaching 6,838.85 mg/L and 3,193.5 mg/L. For laundry wastewater, surfactants decreased by 55% to 12.97 mg/L, but BOD and TSS increased. These findings indicate that while eco-enzyme can reduce specific pollutants like ammonia and surfactants, its application can also elevate COD and BOD levels in some cases. Additional treatment processes, such as aeration or coagulation, are required to achieve effluent standards. Despite its limitations, eco-enzyme holds potential as an environmentally friendly option for industrial wastewater management when integrated with complementary technologies.

Abstract

Universitas Jambi adopted the Green Campus concept and joined the UI Green Metric as a commitment to environmental sustainability. One crucial step is the management of solid waste, particularly organic waste. In 2023, Universitas Jambi generated 835.7 kg of organic waste per day; however, its management at the Temporary Disposal Site remains suboptimal. This study aimed to measure the amount of organic waste from canteens in the Mendalo Campus area, evaluate the effectiveness of the Black Soldier Fly (BSF) method, and design a sustainable organic waste management system. The results show that the BSF method can reduce waste by up to 77.5%, with a Waste Reduction Index (WRI) of 5.16% and an Efficiency Conversion Degree (ECD) of 9.15%. BSF larvae have proven to be effective in processing various types of organic waste, making this bioconversion technique widely applicable at the Universitas Jambi. The proposed management system includes waste collection from sources, transportation, and processing using BSF to enhance the efficiency of organic waste management.
