The purpose of this research was to examine how well a mixture of Moringa oleifera (MO) seed extract and Banana peel powder performed as an alternative to traditional coagulants in improving Batik effluent wastewater. To treat wastewater, coagulation/flocculation and sedimentation are utilized. The seeds of Moringa oleifera were dried, crushed, and sieved, and this process was also done on the banana peel. Jar tests were performed, and the effectiveness of coagulation tests was compared to the use of aluminum sulfate (alum). In comparison to using the mixture of Moringa oleifera seeds extract and Banana peel powder at the prescribed dose of 15 g of moringa seed powder and 5 g of banana peel in a liter of the effluent and 20 g of moringa seed powder in a liter of the effluent provided outstanding results (though none of the mixture gives a clear water) and alum at 5 g/L. In reality, mixture of MO seeds extract plus powder peel and alum reduced turbidity by −39.72% and 77.50%, TSS by 82.44% and 47.98%, TDS by 69.45% and 41.26%, color by −99.21% and 32.67%, conductivity by −149.85% and −280.67%, COD by −49.11% and −101.32%, and BOD by −46.55% and 67.82%, respectively. In contrast to alum, increasing the dosage of MO seed extract and banana peel resulted in a minor pH change and a decrease in conductivity. The usage of a mixture of Moringa oleifera seed extracts and banana peel is recommended to avoid the numerous disadvantages associated with the use of chemical coagulants. This research highlights the potential of utilizing sustainable and locally available materials for effective and eco-friendly treatment of batik effluent, contributing to the development of cleaner and more sustainable practices in the textile industry.
