Abstract

As a lightweight, inexpensive, and easy-to-obtain material, plastic has experienced a significant increase in global production over the last few decades. In addition, the nature of plastic that is difficult to decompose will eventually become plastic waste that accumulates on land and in the ocean. Strategic steps need to be implemented by each country to reduce the amount of plastic waste produced every time. This study uses a geospatial information approach to determine plastic waste pollution, which can be used by integrating various data sources. This study aims to create a dynamic pollution model of mismanaged plastic waste basin levels in Southeast Asia by combining remote sensing data and socio-economic data. The parameters used to determine the plastic waste potential index are the amount of plastic waste generated and socio-economic. The estimation model for plastic waste entering the river was made using the weighting method and overlapping analysis of the existing parameters. The results show that basins in densely populated areas such as the cities of Jakarta, Bangkok, Kuala Lumpur, Hanoi, and Manila have the potential to produce high levels of plastic waste from the mainland.
