Karakterisasi dan Kelimpahan Mikroplastik pada Ikan di Pantai Sukamade Taman Nasional Meru Betiri serta Pemanfaatannya sebagai Video Pembelajaran

Abstract

Plastic waste is a global problem because it can be degraded into micro sizes called microplastics. Microplastics are tiny (<5 mm), so in marine waters, they can easily be internalized in aquatic biota, even though microplastics can absorb harmful environmental pollutants. This descriptive research aims to determine the characterization and abundance of microplastics in fish at Sukamade Beach, Meru Betiri National Park. The research locations were Sukamade Beach for fish sampling and the Biology Educational Zoology Laboratory, Teaching and Education Faculty, Jember University for microplastic identification. The research was conducted from September until December 2022. The methods used in this research included: 1). Preparation and determination of sampling location; 2). Fish sampling; 3). Species identification of fish; 4). Identification of microplastic in selected organs; 5). Analyze data on microplastic character (based on size, form, and color) and abundance (particle per fish and particle of wet weight of the organ). Four fish samples in this research included three species, Eleutheronema tetradactylum, Sardinella lemuru, and Trachinotus botla. The result found 451 microplastic particles in the four fish's gills, stomach, and intestines. The dominant character identified microplastics in fish dominated with 1000-5000 μm in size, fragments, and black color. The average abundance of microplastics is 112,75 particles per fish. The average abundance of microplastics in the gills, stomach, and intestine was 78,72 particles/gram 57,56 particles/gram, and 28,81 particles/gram. The result proved that microplastics entered the body of fish in Sukamade coastal waters, Meru Betiri National Park. The results of the learning videos obtain an average percentage of expert validators of 83% so that they can be categorized as appropriate for use as learning media in the teaching and learning process.
