<![CDATA[Organic waste management remains an environmental challenge in urban areas, including Denpasar City, Bali. The community commonly manages household organic waste through the teba modern system, in which organic waste is allowed to decompose naturally. However, the process is generally carried out without the addition of bioactivators to support decomposition and optimize compost quality. This community service activity aimed to improve community knowledge and awareness of the use of rice washing water as a natural bioactivator for household organic composting. The activity was conducted in the Renon Field area, Denpasar, through material presentation, discussion, educational poster distribution, and seedling distribution. Participant evaluation was conducted using a questionnaire to obtain feedback on participants' knowledge and understanding of organic composting and natural bioactivators. The results showed that 68.8% of participants had previously known about and made organic fertilizer, indicating that basic awareness of organic waste utilization was relatively good. However, participants' knowledge of natural bioactivators, particularly the use of rice washing water, was still limited. Following the socialization, 37.5% of participants stated that the material was well understood and provided additional knowledge about organic composting. Participants also showed positive responses and interest in applying rice washing water as a natural bioactivator independently at home because it is readily available, inexpensive, and easy to apply. The activity also included the distribution of plant seedlings to encourage participants to apply the knowledge gained through the utilization of organic compost. These findings indicate that community socialization can contribute to improving public understanding and awareness of simple, economical, and environmentally friendly approaches to household organic waste management through the use of natural bioactivators.]]>
