Abstract

Mikroplastik merupakan jenis sampah plastik yang berukuran lebih kecil dari 5 mm. Kisaran ukuran partikel mikroplastik tersebut dapat menyebabkan ikan menelan mikroplastik baik secara langsung maupun tidak langsung. Salah satu wilayah pesisir Indonesia yang tercemar oleh sampah plastik yaitu perairan Laut Tuban. Adanya sampah mikroplastik memberikan dampak bagi biota laut khususnya ikan yang menelan mikroplastik akan terjadi translokasi melintasi saluran pencernaan dan memasuki berbagai organ pada ikan. Analisis mikroplastik pada saluran gastrointestinal ikan pelagis dan demersal di perairan Laut Tuban dilakukan secara visual dan pengujian jenis polimer menggunakan FT-IR. Hasil penelitian menunjukkan jumlah partikel mikroplastik yang teridentifikasi pada saluran gastrointestinal ikan pelagis lebih banyak daripada ikan demersal serta bentuk dominan adalah fiber (62%) dengan warna hitam dan ukuran dominan berkisar antara 100-500 µm (72%). Berdasarkan Uji FTIR, tipe polimer yang ditemukan adalah polyethylen dan polyamide. ========================================================= Microplastic is a type of marine debris that is smaller than 5 mm. The range of microplastic particle size can cause fish to swallow microplastic directly and indirectly. One of Indonesia's coastal areas that is polluted by marine debris is the Tuban Sea waters. The presence of microplastic can impact on marine biota, especially fish that ingest microplastics, translocation will occur across the digestive tract and transferred various organs in fish. Microplastic analysis of the pelagic and demersal gastrointestinal tracts in Tuban Sea waters was carried out visually and the type of polymer testing was carried out using FT-IR. The results showed that the number of microplastic particles identified in the digestive tract of pelagic fish was more than demersal fish and the dominant form was fiber (62%) with black color and dominant size ranging from 100-500 μm (72%). Based on the FTIR test, the types of polymers found were polyethylene and polyamide.
