Manado shore is one of the water areas in North Sulawesi that has potential in coastal
tourism. This is proved through the presence of tourists who want to enjoy the underwater beauty by
diving either by snorkeling or by scuba. This study aimed to determine the density and composition of
seabed waste in the waters of Manado shore. Sampling was carried out at 2 stations, the first station
was in the estuary area of the Malalayang River and the second station was in the waters of the
Megamas Manado area. The sampling method was carried out using the belt transect method by
conducting SCUBA dives with a sampling area of 100 meters long and 2 meters wide. The identification
results obtained 7 types of macro-sized marine debris which were classified into 17 types, while mesosized garbage found 6 types of marine debris which were classified into 11 types. The composition for
macro-sized waste is dominated by the type of plastic material (PL code; composition of 31%; weight
of 7,990.025 g) while up to meso is dominated by the type of glass & ceramic material, (GC; 39%; 120.5
g). Macro and meso size marine debris density at the Manado Beach location, for macro size is
dominated by the type of plastic material (PL code; 1.9 items/m2), while the meso size is dominated by
the type of plastic material (PL; 1.42 items/m2). m2).
