Eco-enzyme is a fermented liquid produced from organic kitchen waste and has gained attention as a sustainable, low-cost alternative for wastewater treatment. This study evaluates the effectiveness of eco-enzyme derived from household fruit and vegetable scraps in improving the physical quality of industrial wastewater. Eco-enzyme was produced using a 1:3:10 ratio of organic waste, brown sugar, and water and fermented for six months under semi-anaerobic conditions. Industrial wastewater samples were treated with eco-enzyme at a dosage of 10% v/v and analyzed before and after 48 hours of contact time. Key parameters measured included pH, Total Solid (TS), Total Dissolved Solid (TDS), and Total Suspended Solid (TSS). Results showed a shift in pH from 8.0 to 7.0, TS reduction from 470.1 mg/L to 310.5 mg/L, TDS from 380.0 mg/L to 215.5 mg/L, and TSS from 95.0 mg/L to 50.0 mg/L. These reductions indicate partial degradation and settling of solid contaminants influenced by enzymatic hydrolysis and organic acids present in eco-enzyme. In addition, eco-enzyme application on chili plants increased plant height from 4.0 cm (control) to 5.7 cm after ten weeks. These findings suggest that eco-enzyme has promising potential for small-scale wastewater treatment and agricultural enhancement. However, the absence of replicate measurements and limited parameters constitute significant limitations. Further research is recommended to optimize dosage, fermentation variables, and large-scale application.
