Distribution of Macro Debris in Savu Sea Marine National Park (Kupang, Rote, and Ndana Beaches), East Nusa Tenggara, Indonesia

Marine debris has emerged as a global issue that poses risk to environment systems. This study aimed to investigate the distribution of marine debris in Savu Sea Marine National Park, particularly in Kupang City, Rote Island, and Ndana Island (which are transboundary islands in the Australian and the Indian Ocean). Six beaches were assessed on this study, which comprised of total 12 transects. Debris collected from sampling sites weighed 52.14 kg, with abundance 4.447 ± 1.131 kg/m2 and 215.417 ± 35.609 item/m2. Most debris pieces were accumulated on high tide line and the area that many residents passed through. In terms of type, food wrapper and plastic bag dominated the debris composition due to their occurrence in every transect. It is strongly suggested that beached debris in Kupang and Rote was sourced from the population activities, whereas in Ndana was transported from other places via ocean currents.
