The problem of household waste management in Ketitang Village, Godong District, Grobogan Regency, is triggered by low public awareness, limited infrastructure, and the habit of littering and open burning which results in environmental pollution and health risks. An Nuur University's KKN Group 9 uses the Participatory Action Research (PAR) approach, conducting socialization, cooperative training to build a rocket stove incinerator from local materials (hebel bricks and iron), trial runs, and continued mentoring. This technology burns dry waste at temperatures above 600°C efficiently, with a reduction in smoke emissions of up to 60-80% and a minimum volume of waste to ash. The results include increased awareness of the 3R principle (Reduce, Reuse, Recycle), community participation in RW 01-02, and the ability to manage independently sustainably. This innovation is an environmentally friendly model that deserves to be replicated with routine maintenance and support from the village government to create a clean and healthy environment.
