Pollution of solid waste flowing in river bodies is a major problem that can significantly reduce water quality. Weather factors that occur are thought to have an influence on the abundance of solid waste generation in river flows. This study aims to analyze the effect of rainfall on the abundance of solid waste found in the flow of the Citarum River, West Java. Waste data collection was carried out from April to June and August to November 2021 at four monitoring stations spread across Bandung Regency, West Bandung Regency, and Purwakarta Regency. Data collection of solid waste abundance was carried out using a Framed Pocket Net measuring 2x1x2 meters, while rainfall was obtained from the monitoring results of the Bandung Geophysical Station. The results showed that rainfall 1 day before solid waste sampling had a real effect on solid waste abundance. While rainfall on 3 days, 2 days, and 0 days before solid waste sampling has no real effect. The results of the study are presented in the form of a comparison graph between rainfall and solid waste abundance, as well as an influence graph through linear regression analysis. Therefore, it is necessary to carry out solid waste management, especially when rainfall conditions are high.
