Marine litter is a major global problem; it originates on land and enters the ocean via rivers, coastal erosion, and extreme events. Over time, marine litter collects in coastal areas. As a result, the research on litter dispersal and buildup is critical for successful coastal area management. Addressing the knowledge gap is critical for establishing successful solutions to fight that problem. In recent years, a variety of remote sensing techniques have been used to better understand litter abundance, distribution patterns, and dynamics in marine as well as coastal ecosystems. Marine litter detection and quantification are carried out using aircraft-based imaging systems, satellite images, and unmanned aerial vehicles (UAVs). The purpose of this study was to create a beach litter monitoring system or technical reference using a small UAV and geographic information system (GIS), with the test location at Batu Belig Beach, Badung Regency, Bali, Indonesia. The box-plot approach was used to determine the reflectance threshold on the orthophoto. GIS is used to determine the regions with and without litter based on the set threshold values. To verify the model, Slovin’s Formula was used to collect the sample, with a confusion matrix indicating an accuracy of 80%. This monitoring system provides a simple approach for identifying and measuring litter, even with only one person handling the entire operation. The outcomes of this analysis indicated that the majority of litter at the study location was made up of white plastic bags and styrofoam. As a last step, portraying litter abundance as a percentage per square meter was considered.
