Abstract

Mikroplastik merupakan partikel plastik yang berukuran antara 1 µm hingga 5000 µm. Salah satu organisme perairan yang menerima dampak secara langsung terhadap akumulasi mikroplastik adalah Crustacea. Crustacea seperti udang merupakan biota perairan yang memiliki berbagai cara makan seperti scavenger, filter feeder, ataupun deposit feeder sehingga lebih rentan dalam mengakumulasi mikroplastik karena makanan organisme tersebut memiliki ukuran relatif sama dengan mikroplastik. Apabila mikroplastik yang terakumulasi pada udang pindah ke tingkat trofik yang lebih tinggi seperti manusia, maka akan memberikan potensi risiko kesehatan, sehingga diperlukan perhitungan untuk mengetahui nilai estimated daily intake (EDI) melalui identifikasi karakter fisik mikroplastik pada udang vaname (Litopenaeus vannamei) dan untuk mengetahui karakter polimer mikroplastik pada udang vaname (Litopenaeus vannamei). Analisis data yang digunakan ialah analisis deskriptif kuantitatif dengan mengkaji karakter fisik mikroplastik seperti bentuk, ukuran, dan warna. Sedangkan karakter polimer mikroplastik diidemtifikasi melalui Fourier transform infrared (FTIR) serta perhitungan Estimated Daily Intake (EDI) untuk mengetahui estimasi konsumsi harian pada manusia. Hasil kelimpahan rata-rata mikroplastik pada cephalothorax sebesar 131,77 partikel/individu, pada abdomen sebesar 109,23 partikel/individu, dan caudal sebesar 35,10 partikel/individu. Karakter fisik mikroplastik yang dominan ditemukan pada cephalothorax, abdomen, dan caudal adalah bentuk fragmen, warna biru, dan ukuran 10 – 50 μm. Jenis polimer yang teridentifikasi adalah polyamide (PA), polyurethane (PU), dan cellophane atau selulosa. Nilai estimated daily intake (EDI) pada cephalothorax adalah 37,26 partikel/orang/hari, abdomen adalah 20,39 partikel/orang/hari, caudal adalah 159,53 partikel/orang/hari, dan seluruh tubuh adalah 29,90 partikel/orang/hari.

Microplastics are plastic particles ranging in size from 1 µm to 5000 µm. One aquatic organism that is directly impacted by the accumulation of microplastics is Crustacea. Crustaceans, such as shrimp, are aquatic biota that have various feeding methods including scavenging, filter feeding, and deposit feeding, making them more vulnerable to accumulating microplastics because their food items are relatively similar in size to microplastics. If microplastics accumulated in shrimp transfer to higher trophic levels, such as humans, this could pose potential health risks. Therefore, it is necessary to calculate the estimated daily intake (EDI) by identifying the physical characteristics of microplastics in vaname shrimp (Litopenaeus vannamei) and to determine the polymer characteristics of microplastics in vaname shrimp (Litopenaeus vannamei). The data analysis used is quantitative descriptive analysis by examining the physical characteristics of microplastics such as shape, size, and color. Meanwhile, the polymer characteristics of microplastics were identified using Fourier transform infrared (FTIR) spectroscopy, along with the calculation of estimated daily intake (EDI) to estimate daily human consumption. The average abundance of microplastics was 131.8 particles per individual in the cephalothorax, 109.2 particles per individual in the abdomen, and 35.1 particles per individual in the caudal region. The dominant physical characteristics of microplastics found in the cephalothorax, abdomen, and caudal regions were fragment shapes, blue color, and sizes ranging from 10 to 50 μm. The types of polymers identified were polyamide (PA), polyurethane (PU), and cellophane or cellulose. The estimated daily intake (EDI) values were 37,26 particles/person/day for the cephalothorax, 20,39 particles/person/day for the abdomen, 159,53 particles/person/day for the caudal region, and 29,9 particles/person/day for the whole body.
