Many studies have been trying to solve waste problems and reduce the amount of waste, but waste problems are at a standstill nowadays in many places. Knowledge about household waste management has been given to many people in many societies [1-3]. Many concerns are brought to the attention of those around them. This study focuses on the pain point that has an influence on the failure of waste reduction participation. The data collected by observation on three homes, focused on the activities to support waste reduction by reusing the reusable waste and separating the recyclable waste for sending them to be recycled further. In the three homes in this study, there are people with knowledge and awareness about waste reduction in society and around the world. They try to support waste reduction in their homes. The results show that the important point is the knowledge and awareness of waste problems and the intention to participate in waste reduction in the community and indirectly in the world of the key man of the home or community.Environmental ScienceArticleSCOPUS10.15244/pjoes/1881882-s2.0-85217242220
