<![CDATA[Household waste is a major source of urban waste requiring management at the source, particularly in the RW 012 Cipinang Melayu neighborhood. This community service activity aimed to enhance the knowledge and skills of PKK members in RW 012 Cipinang Melayu regarding the processing of organic household waste into eco-enzymes and derivative products. The activity was conducted in July 2026 at the RW 012 Cipinang Melayu Hall, East Jakarta, involving 15 participants through an educational-participatory approach comprising lectures, demonstrations, and hands-on practice. Evaluation utilized a pre-test and post-test design to measure changes in participants' knowledge and attitudes, alongside observations of practical skills during the training. Results showed an increase in the average knowledge score from 7.87 to 13.13 (maximum score of 14) and an attitude score increase from 3.58 to 4.71. All participants successfully produced three 16-liter jars of eco-enzyme and processed them into 5.26 liters of multipurpose liquid soap, 3.39 liters of scented floor cleaner, and 0.9 liters of hand sanitizer at the training scale. The activity demonstrated that the educational-participatory approach effectively improved participants' knowledge and basic practical skills in converting organic waste into useful products. Follow-up assistance is required for formulation standardization, product quality and safety testing, and the development of marketing strategies to ensure the program's sustainability.]]>
