| Abstract | Laundry wastewater is a source of environmental pollution due to its content of organic matter, detergents, and suspended solids, which can elevate levels of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS). One environmentally friendly wastewater treatment method is phytoremediation using a combination of water hyacinth (Eichhornia crassipes) and water spinach (Ipomoea aquatica). This study aimed to determine the effectiveness of combining these two plants in reducing BOD, COD, and TSS levels in household laundry wastewater in Medan Amplas District, Medan City, in 2026. The study employed a quasi-experimental method with a one-group pretest-posttest design, utilizing retention times of 2, 4, and 6 days. A 20-liter sample of laundry wastewater was divided into three treatment reactors and one control reactor. Each treatment reactor contained 5 liters of wastewater and a combination of 250 grams each of water hyacinth and water spinach. Laboratory testing was conducted for BOD, COD, and TSS parameters, followed by univariate and bivariate data analysis using the Paired Sample t-test. The results showed that BOD levels fluctuated—shifting from an initial value of 50 mg/L to 71 mg/L (day 2), 45 mg/L (day 4), and 54 mg/L (day 6)—indicating that the plant combination was not effective in reducing BOD levels. Conversely, COD levels decreased from 188 mg/L to 169 mg/L, 145 mg/L, and 88 mg/L, with the highest removal efficiency of 53.19% achieved on day 6. TSS levels also decreased from 149 mg/L to 66 mg/L, 38 mg/L, and 41 mg/L, with the highest removal efficiency of 74.50% achieved on day 4. Statistical analysis results indicate that the treatment influenced changes in BOD, COD, and TSS levels (p<0.05). Thus, the combination of water hyacinth and water spinach is effective in reducing COD and TSS levels, but not yet effective in reducing BOD levels in laundry wastewater. | 1 |
