Abundance and Composition of Solid Waste in the Citarum River, West Java Province

Abstract

The Citarum River is the longest and largest river in West Java and is widely used by the community for various purposes. One of the problems that occurs in rivers is the generation of solid waste that flows into the river. Therefore, this study aimed to analyze the abundance and composition of solid waste on the surface of a river during a certain period. The study was conducted from April to June and August to November 2021. Sampling was carried out once a month with three repetitions, namely morning, noon, and evening, at the five sampling stations. Station locations were divided based on the type of flow, namely, on the mainstream of the Citarum River and tributary streams. The sampling of solid waste is carried out using a frame pocket net (FPN) shaped like a net to capture solid waste that flows on the surface of the river. The highest waste abundance was 0.1569 kg/m3· h in the urban areas. The type of waste that dominated the river was organic waste, which reached 62.8%. Other types of solid waste found were macroplastics, hazardous and toxic materials, metals, rubber, textiles, and paper. Solid waste management needs to be carried out based on the area and is sustainable, and can be pursued by implementing 3R (reuse, reduction, and recycling).
