Abstract Household organic waste remains a significant environmental problem in urban areas, including Kupang City, East Nusa Tenggara. Inadequate waste management creates negative impacts on public health and the environment. This community service programme aimed to improve the knowledge and skills of members of the Indonesian Catholic Women’s Association (WKRI), Maulafa Branch, in processing household organic waste into Liquid Organic Fertiliser (LOF) using a circular economy approach. The programme was conducted on 19 June 2026 in Neighbourhood Unit 019, Oebufu Subdistrict, Maulafa District, Kupang City, and involved 20 participants and six university students. The methods included counselling, demonstrations, hands-on practice, pre-tests, post-tests, skills observation, and monitoring. The evaluation results showed that the participants’ average knowledge score increased from 42% to 88%, representing an improvement of 46 percentage points. In addition, 75% of participants were able to perform at least four of the five main stages of LOF production correctly. These findings indicate that participatory training can strengthen participants’ basic capacity to process kitchen waste and support the implementation of a circular economy at the household level.
