<![CDATA[Household waste management remains a major environmental challenge in urban areas due to rising waste generation and limited implementation of household-level waste segregation. This community service activity aimed to improve community knowledge and awareness regarding household waste segregation among residents of Gomong Village, Mataram City, West Nusa Tenggara. The program was conducted on June 10, 2026, using a participatory approach involving 13 community members and local micro-enterprises. Data were collected through observations, questionnaires, interviews, and documentation, followed by educational sessions and the distribution of posters promoting waste segregation and the Reduce, Reuse, and Recycle (3R) principles. The findings revealed that 76.9% of participants disposed of household waste directly without prior collection, and 76.9% did not separate organic and inorganic waste. Although 69.2% had previously received information about waste management, proper segregation practices were still rarely implemented. The educational activities enhanced participants’ understanding of waste categories, the importance of segregation, and the environmental impacts of improper waste disposal. Overall, the program contributed to increased awareness and encouraged more responsible household waste management behavior. Continuous environmental education and community engagement are recommended to strengthen sustainable waste segregation practices and support cleaner, healthier, and more sustainable urban communities.]]>
