Abstract
This study aims to compare the abundance and types of microplastics in water, sediments, and digestive tracts of sea urchins Diadema setosum, in Untung Jawa Island and Tidung Island, Seribu Islands. Samples of sea urchins, water, and sediment were taken from 15 different locations based on the location of the biota colony. Samples of the digestive tracts of sea urchins were analyzed by dissolving them at 65% HNO3, water samples (20 l) were filtered with a 300 μm plankton net, and sediment samples (200 g) were dried in the oven first, then each sample was given NaCl to saturate. Each sample (1 ml) is placed in the Sedgwick Rafter Chamber to be examined under a microscope. The results showed that the abundance of microplastic in Untung Jawa Island was higher at 99.88 ± 1.79 particles l−1 in water, 110,737.77 ± 4,197.61 particles Kg−1 particles in sediment, and 2,175.55 ± 584.26 particles Ind−1 in the digestive tract of sea urchins. On Tidung Island microplastic abundance contained in the water amounted to 87.4 ± 9.61 particles l−1, the sediment of 87,626.66 ± 4,957.00 particles Kg−1, and in the digestive tract of sea urchins to 1,786.66 ± 451.17 particles Ind−1.
