Abundance and Types of Microplastics in the Water of Sukaraja

Sukaraja coastal waters are a place used by the community as a center to find fish to be traded. However, the sustainability of this beach has been polluted by garbage which is dominated by plastic materials. Decomposition of plastic waste takes a very long time. The results of the decomposition are called mocroplastics which have a size < 5 mm. Its very small size can make it a food ingredient for aquatic biota, causing bad impacts. This study uses a descriptive quantitative approach with random sampling method. The research location points were carried out at 3 statitions with 2 times of taking, namely the time of high tide and low tide. The time of the research was in April 2021. The total abundance of microplastics found was 36 x 10 2 particles/m3. The highest abundance was found at Station II of 20,66 x 10 2 particles/m3, which is where the most plastic waste accumulates. While the lowest abundance was found at Station III with an abundance of 4,66 x 10 2 particles/m 3 . This is presumably because the location of Station III is far from the shoreline and is clean of garbage. The types of microplastics found in persim at Sukaraja Beach are fragment, film, fiber, pellet types. The highest average abundance of microplastics was found in the sobeast fragment types of 14,66 x 10 2 particles/m 3 . And the lowest average abundance of microplastics is the type of film of 3,33 x 10 2 particles/m 3
