PERBANDINGAN KELIMPAHAN MIKROPLASTIK PADA IKAN TERI (Stolephorus sp.), UDANG JERBUNG (Penaeus merguiensis) DAN KERANG DARAH (Anadara granosa) YANG DIDARATKAN DI DAERAH SUNGSANG, KABUPATEN BANYUASIN PROVINSI SUMATERA SELATAN
Microplastics are a type of pollutant that has recently received considerable attention due to their resistance to natural degradation and their very small size. This small size allows microplastics to easily enter the bodies of aquatic organisms through ingestion or filtration processes and subsequently accumulate within the food chain. Anchovies (Stolephorus sp.), banana shrimp (Penaeus merguiensis), and blood cockles (Anadara granosa) were selected for this study because they have different habitats and feeding behaviors, making them suitable indicators for describing the distribution of microplastics in aquatic environments. This study aimed to determine the number, types, shapes, sizes and abundance of microplastics in anchovies, banana shrimp, and blood cockles landed in the Sungsang area, Banyuasin Regency, South Sumatra. Samples were collected from fishermen and collectors, then analyzed in the laboratory by dissolving organic matter using a 10% KOH solution and separating microplastics using a NaCl solution. The samples were then filtered and observed using a trinocular microscope. The results showed that blood cockles had the highest abundance of microplastics at 1.09 particles/gram, followed by banana shrimp at 1.06 particles/gram and anchovies at 1.04 particles/gram. The types of microplastics identified included film, fragments, fibers, and foam, with film and fragments being the dominant types. In terms of size, the microplastics found had an average length ranging from 3.44 to 1098 µm.
