Laundry wastewater is classified as domestic wastewater that has a turbidity of 25 – 150 NTU and can cause an environmental problem. Moringa seeds are plants that can be used as natural coagulants for the treatment of wastewater containing suspended colloids. The main purposes of this study are to extract proteins from moringa seeds into a bio-coagulant, determine the optimum time for drying the extract form into powder form, calculate the percentage of protein in the extract form and powder form and determine of turbidity removal efficiency using the extract form and powder form in condition low turbidity, medium turbidity, and high turbidity. Powdered bio-coagulant is obtained through several stages including moringa seeds size reduction into 250μm, oil extraction from solids using n-Hexane, protein extraction from solids using NaCl solution, protein separation by centrifugation process, and drying the protein using vacuum drying method at 40oC and 70 mbar. The best results were obtained by the extraction process using 2 M NaCl solution and an optimal drying time of 3 hours. Protein percentage in the extract form of bio-coagulant was 1.09% with a turbidity removal efficiency of 76.15%, while the protein percentage in the powder form was 80.75 % with a turbidity removal efficiency of 30.35%.
