As a lightweight, inexpensive, and easy-to-obtain material, plastic has experienced a significant increase in production in the world over the last few decades. In addition, the nature of plastic that is difficult to decompose will eventually become plastic waste that accumulates, both 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 untreated plastic waste in rivers in Southeast Asia by combining remote sensing data and socioeconomic data. The parameters used to determine the plastic waste potential index are the amount of plastic waste generated, socioeconomic, and climate. Remote sensing data used are DEM, slope, rainfall, and wind speed. Meanwhile, data on population density, human development index, and gross domestic product are used as socioeconomic parameters. The estimation model for plastic waste entering the river and the streamflow model were 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. The increased amount of plastic waste is influenced by climatic conditions in certain months, which will be of high value in September – February and low in the middle of 2021.
