Abstract

Waste management of single-use plastic bags is a common problem in metropolitan areas, including Yogyakarta, Sleman, and Bantul. It urges the needs to evaluate the existing regulation that decide the most suitable institution to overcome this issue. This research used mixed method. Regulations related to Law No. 18/2008 on Waste Management were inventoried and analysed for determining institutional related keywords. The results of content analysis are related to the volume of waste at Integrated Waste Treatment Area (IWTA) and community participation's level. Yogyakarta does not instruct specific institutions which are in charge in sorting, collecting, and transporting waste to Temporary Trash Disposal Sites. In contrast, Sleman specifies the institutions, yet it does not include the obligation of the community level. Meanwhile, Bantul clearly regulates institutions at the community level, authority, and budget. Based on the data obtained from Piyungan IWTA, Yogyakarta is the largest contributor of waste (51.02%), followed by Sleman (29.10%) and Bantul (12.79%). However, Bantul has the highest community participation in plastic waste management (93.9%), followed by Yogyakarta (89.7%) and Sleman (88.0%). It is evident that region with the absence of waste management institution tend to generate greater amount of waste, and lower level of community participation.
