Sediment samples were taken in November 2019 with a purposive sampling method using sediment cores at 3 different stations namely the TPI River Estuary (Fish Auction Place), the LPWP River Estuary (Coastal Development Institution), and the BBPBAP River Estuary (Central Brackish Aquaculture Fisheries Center ), at 3 points inside it is 20 cm, 40 cm and 60 cm.

The microplastic color is dominated by brown as many as 466 particles, while the microplastic color is the least pink and clear as much as 2 particles / 50 g of dry sediment.
