Waste is defined as the remains of materials that are no longer used and can cause pollution in the environment. The Jatigede Reservoir has the potential for the environment and was built by damming the Cimanuk River, but at several points, the Jatigede Reservoir area is polluted by waste. In this research, survey and waste collection methods were used using purposive sampling techniques to determine sampling points at the three stations. Data regarding waste is processed using an explanatory descriptive method and displayed in graphic form via Microsoft Excel. The land area is calculated using ArcMap software to map waste patterns. Based on the waste found, The Cimanuk River has the largest distribution of waste, with the largest composition of waste being organic type waste. While the study highlights the significant amount of waste in the Jatigede Reservoir originating from the Cimanuk River, conducting additional research that encompasses the entire reservoir will provide helpful insights for reservoir management. Subsequently, the investigation of waste in the Cimanuk River Basin will expand the data to bolster the management of rivers, lakes, and reservoirs.
