Impact of rainfall on the abundance of solid waste found in the flow of the Citarum River

Abstract

Abstract 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 Framed Pocket Net, 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 correlation shown between day-1 rainfall and the abundance of solid waste is 0.3701, which is a low relationship. Meanwhile, based on the influence test, it shows that rainfall in day-1 has a weak effect on the abundance of solid waste. However, solid waste management still needs to be carried out, especially during the rainy season.
