Increased population and economic capacity of the community indirectly affects the amount of household waste produced by the community. Unfortunately, this is not accompanied by good waste management from the community level. Management of household waste at the community level can be done by sorting waste. The habit of people to dispose of garbage without sorting can be a problem in implementing 3R activities (Recycling, Reducing, Reusing). The purpose of this study is to find out what factors influence the community in sorting household waste. This research is based on the Theory of Planning Behavior (TPB) which considers several factors such as attitudes, subjective norms, and behavioral controls to influence someone to make intentions in behavior and expand the TPB conceptual model to overcome gaps. The results of this study came from a survey with 301 respondents in two locations namely DKI Jakarta and Depok. The results of this study indicate that attitudinal factors have the most significant influence on the intention and behavior of sorting garbage. While other factors such as demographics, subjective norms and perceptions of behavioral control do not have a significant effect.
