Banjar Regency through the Banjar Regent Regulation No. 8/2016 on reducing the Use of Plastic Bags is the first Regency to make arrangements to reduce the use of plastic bags. However, after the implementation of the Perbup, there has been no significant change to the accumulation of plastic waste in Banjar Regency. In fact, plastic waste takes a very long time to decompose, so it has a bad impact on the environment for a long time. This shows the need for a study on the effectiveness of Perbup. This study aims to analyze the effectiveness of Perbup on reducing the use of plastic bags. The type of research used is qualitative with an exploratory method through an inductive approach. Data collection techniques are carried out through observation, interviews, and documentation. Observations were made at the Final Disposal Site (TPA), 23 modern market places, and 14 local traditional market places. The results showed that the implementation of Perbup has not been effective in reducing the use of plastic bags, and has not been optimal because it is still in the socialization and supervision stages. There has been no firm action in the form of fines or sanctions for violators of these regulations.
