    Currently, decreasing water quality due to contamination of industrial wastes that are discharged to environment is a very serious problem, one of them is coconut milk industry wastewater. MSL (Multi Soil Layering) is an alternative method that can be effectively used in industrial wastewater treatment processes. Utilization of modified MSL method with the addition of rice husks may increase the yield of coconut milk industry wastewater treatment. This study aimed to determine the effectiveness of TSS, BOD, COD, and E. coli reduction using modified MSL method for coconut milk industry wastewater based on aeration and non-aeration processes and variation of flow rate. This experimental study used modified MSL equipment with the addition of rice husks which consisted of andosol soil, coconut shell charcoal, iron powder, rice husk and perlite which were arranged like brick construction. The indicators observed in this study were the effect of aeration and non-aeration processes and variations of flow rate on parameters changes of TSS, BOD, COD, and E.coli count. Variations of flow rate used in this study were 5; 10; 20; and 40 ml / minute. The research results suggested that modified MSL method with rice husk is efficient and effective. In the aeration process, the decrease in turbidity reached 99.79%; BOD 35.68%; COD 86.64%; and E.coli 99.79% while in the non-aeration process, the decrease in turbidity reached 98.66%; BOD 33.01%; COD 84.62%; E.coli 99.92%; Overall, the effective flow rate for reducing pollution levels in the coconut milk industry wastewater based on these indicators was 5 ml / minute, both in aeration and non-aeration treatments.
