Abstract Plastic waste is the dominant type of marine waste found. The plastics are degraded in physics, chemistry and biology to a size of <5 mm. Sea cucumbers are deposite feeder type animals that get food by stirring up sediments so that there is microplastic content in sea cucumbers. This research aims not only to analyze the microplastic density in sediments and sea cucumbers but also to analyze the correlation between microplastic density in sediments and sea cucumbers. This research was conducted from February to April 2018. The research data was the descriptive with purposive random sampling and correlational studies method. Based on calculation analysis, microplastic found in sediments and sea cucumbers on Tidung Island and Bira Besar Island, consists of 4 (four) types. There are fiber with 2722 particles/g; 1982 particles/g, fragment 254 particles/g; 547 particles/g, film 100 particles/g; 50 particles/g and pellets 14 particles/g; 9 particles/g. Microplastic found in sea cucumbers consists of Tidung Island and Bira Island. Consist 4 (four) types, which are fiber, 2033 particles/g; 1247 particles/g, 137 particle fragments/g; 183 particles/g, film 60 particles/g; 69 particles/g and pellets 9 particles/g; 4 particles/g. Correlation results showed a positive correlation with microplastic in sediments and in sea cucumbers.
