Used cooking oil is household waste generated from the repeated use of cooking oil. Improper disposal of used cooking oil can pollute the environment, clog drainage systems, and reduce water and soil quality. One way to manage used cooking oil waste is to utilize it as a useful product, such as aromatherapy candles. The JELITA program (Jelantah Jadi Lilin Aromaterapi) aimed to provide education and skills to residents of RT 07, Sendang Village, Bringin District, in processing used cooking oil into aromatherapy candles. The activity was conducted participatively through three stages: socialization, demonstration of aromatherapy candle production, and evaluation. The production process included purification using wood charcoal, mixing with stearic acid, adding lavender essential oil, and molding the candles. The results showed increased knowledge, environmental awareness, and skills among participants in processing used cooking oil into useful products.
