Abstract

The use of reusable shopping bags is an effort to tackle single-use plastic waste. Despite widespread information on plastic dangers, its usage remains high due to an instant culture. This study aims to determine the influence of attitude toward plastic waste danger information, perceived benefits, and subjective norms on the behavior of using reusable shopping bags among adolescents in Semarang City. Utilizing the Theory of Planned Behaviour (TPB). Explanatory quantitative method with purposive sampling of 100 adolescents (10-18 years). Data analysis using multiple linear regression. Results show that simultaneously, all three independent variables significantly influence the behavior of using reusable shopping bags (sig 0.000 < 0.05) with a contribution of 58.8%. Subjective norm is the most dominant factor. In conclusion, environmental campaigns need to focus on creating trends through peers and eco-influencers.
