Abstract

The water pollution in Ciliwung river has 83.5% of its content coming from detergent waste of washing clothes in the household environment. One of the ways to process detergent waste before disposing it into the bodies of water is through bioremediation. The use of EM4 (Effective Microorganisms) can accelerate the decomposition of materials contained in detergent waste. This research aims to analyze the color change parameters, pH, TDS (Total Dissolved Solids), DO (Dissolved Oxygen), and detergent. Observations were carried out for 7 days which were then compared to the Government Regulation No. 22 of 2021. The results were also analyzed on the mortality rate of Molly fish (Poecilia latipinna). This research method uses CRD (Completely Randomized Design) which consisted of control treatment (without EM4), treatment A (15 mL of EM4), and treatment B (30 mL of EM4) with 3 replications. Based on the results, it was found that there was a visual color change from gray to light brown (treatment A) and dark brown (treatment B). The results are compared with the quality standards of Government Regulation No. 22 of 2021 Appendix VI Class II River Water Quality Standards. Overall, treatment A at a wastewater volume of 1 liter has an influence in improving the quality of detergent wastewater before it is discharged to the water body even though it has not yet meet the quality standard. The DO value (quality standard ≥3.9 mg/L) changed from 1.6 mg/L to 3.9 mg/L. Total detergent (quality standard <2 mg/L) changed from 3.5 mg/L to 2.1 mg/L. Molly fish mortality of 83% was better than treatment B of 100%. Meanwhile, the pH value (quality standard 7-9) changed from 7.7 to 7.5 (both still within the quality standard range) and the TDS value (quality standard <1000 mg/L) increased from 583 to 1069 mg/L.
