The influence of the textile industry on environment, as well usage raw materials and natural resources, is becoming a major problem. It no longer sufficient to have product that simply safe for humans; must also be ecologically throughout its entire life cycle. As result, there has been shift toward employing enzymes in sector promote eco-friendly production. goal this research create an environmentally friendly discharge printing cotton wool textiles, dyed with various plant extracts (Ficus benjamina, Psidium guajava leaves, Solanum melongena peel, Brassica oleracea var. capitata rubra) under varied circumstances by using polyphenol oxidase (PPO) peroxidase (POD) extracted from taro corms (Colocasia antiquorum) instead harmful reducing or oxidizing agents. enzyme extraction temperature was 25°C, solute-liquid ratio (1:4 (w/v)) at pH 5.0 after treatment time 5 min. oxidative were analyzed Gas Chromatography-Mass Spectrometer (GC-MS) Analysis, which verified presence Retinol component molecular weight 286.45 g/mol retention 14.7 min, regarded proof existence enzymes. activity isolated increases over time, PPO having highest 180 seconds wavelength 420 nm. POD achieves peak seconds, 436 observed. These allow them employed agent. effects concentration, paste, enzymatic treatment, effect mixing extract some agents studied determine efficiency. results indicate rates reached about 40–57% 3 samples one. Mixing other different concentrations led higher rate, 60–66%, color half-tones obtained depending difference ratio, pH, factors affecting removal. observed tensile strength printed constant pesidium guava-dyed sample, while remaining increased 1–4%, except sample ficus decreased. While 4% decreased 13% considered acceptable range. obtaining halftones result partial occurred due biological oxidation extract, vital alternative toxic
