Abstract The fishing port is an important supporting facility for achieving high-quality of fishery production. Maintaining the quality of fishery products is needed by optimizing the function of fishing ports as they are the cutting edge and a prime mover in the management and utilization of fish resources and port environment, ranging from preproduction, production, processing, and marketing. On the other hand, the fishing port has various environmental problems such as waste management, water quality degradation and liquid waste management. The objective of this study is to identify the solid waste input to a fishing port by using remote sensing approach. The research was conducted in Karangantu Fishing Port (Pelabuhan Perikanan Nusantara Karangantu), located in Serang, Banten. This study shows that the high-resolution satellite imagery was proven to be able to estimate the solid waste input to the fishing port area. The result shows that solid waste input to Karangantu Fishing Port was estimated to be 142.95 tons in 2020, which was derived from office activities, shipping activities, and tourist activities surrounding fishing port area. The method approach from this study is expected to support environmental management in the other fishing port areas.
