Manufacturing detergent using Cocamide-DEA surfactant and saponin from binahong (Anredera Cordifolia (Ten) Steenis) leaf extract

The use of detergents is increasing and is directly proportional to population growth. Surfactants commonly used in detergents are ABS (Alkyl Benzene Sulfonate) or LAS (Linear Alkylbenzene Sulfonate), which can produce waste that is difficult to degrade in the environment. This study aims to examine the formulation of detergents from a combination of cocamide-DEA and saponin surfactants derived from binahong leaf extract (Anredera cordifolia (Ten.) Steenis), with the addition of lipase enzyme additives. Detergents are formulated with 12 variations of Cocamide-DEA concentrations (10% and 15%), saponin extract concentrations (saponin extract and aquadest ratios of 15%:50%; 20%:45% and 25%:40%), and lipase enzymes (3% and 5%). The resulting detergent has a pH of 10.53-10.78 and a density of 1.023-1.049 g/mL. All formulas meet SNI 06-476-1996 on liquid laundry detergent. The best formulation variation detergent power is 61 NTU, obtained in the formulation of 20%:45%, cocamide-DEA surfactant of 15% (w/w), and lipase enzyme of 5% (w/w). Detergent waste has a pH of 8.37, TSS of 26 mg/L, BOD of 39.03 mg/L, and COD of 93.14 mg/L. These characteristics have met the Wastewater Quality Standards for Laundry Businesses and/or Industrial Activities, and their value is much safer than that of commercial detergents.
