<![CDATA[Household organic waste management remains an environmental challenge because a considerable amount of household waste is not sufficiently utilized at its source. One alternative that has received increasing attention is the conversion of organic waste into eco-enzyme through fermentation. This study aims to analyze the use of eco-enzyme as an innovation for household organic waste management, identify its benefits and supporting factors, and examine its potential as a public sector innovation in the context of Kupang City. This study employed a literature review approach using descriptive-analytical methods. The literature consisted of 22 scientific articles published between 2021 and 2026 that discussed eco-enzyme utilization in waste management, agriculture, household products, environmental education, and community empowerment. The findings indicate that eco-enzyme can serve as an alternative for utilizing household organic waste because its production process is relatively simple and the resulting product can be used for various purposes, including liquid fertilizer and household cleaning agents. Its successful implementation is influenced by knowledge, skills, direct practice, participation, continuous assistance, and institutional support. From a public sector innovation perspective, eco-enzyme has the potential to become one approach to reducing organic waste at the source through collaboration among local government, communities, universities, schools, and community organizations. However, eco-enzyme should be positioned as part of a broader waste management strategy rather than as the sole solution to urban waste problems.]]>
