Tea waste is waste from the tea industry, is quite a lot and has not been used optimally. This study aims to obtain the most effective green tea waste extraction conditions using MAE (Microwave Extraction Assisted) to produce green tea extract that has antioxidant optimum. From the research, the optimum MAE conditions are 450 W power, 60% ethanol, solid solvent comparison 1: 8 and 8 minutes extraction to produce extracts with optimum levels of polyphenols. Extracts obtained have moisture content of 7.83%, pH 5.5, and total polyphenols, total flavonoids, gallic acid, catechin, EGCG and caffeine respectively by 7.1%, 1.04%, 2.76%; 0.83%, 5.18% and 1.03%. Compared with the existing reference, extracts obtained qualify as cosmetic raw materials.
