Abstract
Plastik banyak digunakan dalam berbagai macam keperluan manusia. Sampah plastik yang sudah tidak digunakan dapat masuk ke perairan laut dan terdegradasi menjadi partikel yang lebih kecil, yang biasa disebut mikroplastik. Keberadaan mikroplastik diperairan dapat berdampak buruk bagi biota termasuk ikan. Mikroplastik dapat terakumulasi pada organ insang, saluran pencernaan dan daging ikan. PPN Prigi merupakan pelabuhan yang mendaratkan ikan ekonomis penting di Jawa Timur. Beberapa ikan ekonomis penting yang didaratkan di PPN Prigi antara lain ikan tuna sirip kuning (Thunnus albacares), layang (Decapterus spp), layur (Trichiurus lepturus) dan kuniran (Upeneus sulphureus). Adapun tujuan dari penelitian ini adalah untuk mengetahui kandungan mikroplastik pada ikan ekonomis penting tersebut; untuk mengetahui kelimpahan mikroplastik pada ikan ekonomis tersebut dan mengetahui apakah terdapat perbedaan jumlah kelimpahan mikroplastik pada keempat spesies ikan tersebut. Pengambilan sampel ikan dilakukan pada bulan Agustus 2020. Sampel ikan yang digunakan masing- masing berjumlah 10 ekor disetiap spesies. Organ ikan yang dianalisis yaitu insang, saluran pencernaan dan daging. Analisis laboratorium terdiri dari preparasi sampel, penghancuran bahan organik menggunakan larutan Fe (II) 0,05 M dan H202 30%, penyaringan sampel menggunakan kertas Whatman no 41 dan identifikasi sampel menggunakan mikroskop untuk mengetahui jumlah dan jenis mikroplastik. Setelah sampel di identifikasi kemudian dilakukan analisis data. Total sebanyak 37 dari 40 sampel ikan yang diteliti terkontaminasi mikroplastik baik pada organ insang, saluran pencernaan dan daging. Jenis mikroplastik yang ditemukan antara lain fiber dan fragment. Hasil penelitian menunjukkan terdapat perbedaan kelimpahan total mikroplastik antar setiap ikan (p<0.05). Kelimpahan total mikroplastik pada ke-empat spesies ikan berkisar 0,00- 0,09 partikel/ gram dan 3,4- 4,6 partikel/ individu. Kelimpahan mikroplastik pada organ setiap ikan cukup variasi antara lain pada ikan kuniran kelimpahan tertinggi terdapat pada organ insang, disusul saluran pencernaan dan daging; ikan layang, layur dan tuna sirip kuning kelimpahan tertinggi terdapat pada organ daging disusul insang dan kelimpahan terendah pada organ saluran pencernaan. Kelimpahan mikroplastik pada organ yang cukup bervariasi diduga karena adanya perbedaan fungsi organ dan interaksi ikan dengan perairan sebagai sumber mikroplastik.
English Abstract
Plastics are widely used in various human needs. Plastic waste that is no longer used can enter marine waters and be degraded into smaller particles, which are commonly called microplastics. The presence of microplastics in waters can have a negative impact on biota, including fish. Microplastics can accumulate in the gills, digestive tract and fish muscle. PPN Prigi is a port that lands economically important fish in East Java. Some of the economically important fish landed at PPN Prigi include yellowfin tuna (Thunnus albacares), mackerel scad (Decapterus spp), the largehead hairtail (Trichiurus lepturus) and silver goatfish (Upeneus sulphureus). The purpose of this study was to determine the content of microplastics in these economically important fish; The purpose of this study was to determine the abundance of microplastics in these economical fish and to determine whether there were differences in the abundance of microplastics in the four fish species. Fish sampling was carried out in August 2020. Each fish sample used was 10 in each species. The fish organs analysed were gills, digestive tract and fish muscle. Laboratory analysis consisted of sample preparation, destruction of organic matter using a solution of 0.05 M Fe (II) and 30% H202, filtering samples using Whatman paper no 41 and identification of samples using a microscope to determine the number and types of microplastics. After the sample is identified, then data analysis is carried out. A total of 37 of the 40 fish samples studied were contaminated with microplastics in the gills, digestive tract and fish muscle. The types of microplastics found included fiber and fragments. The results showed that there were differences in the total abundance of microplastics between each fish (p<0.05). The total abundance of microplastics in the four fish species ranged from 0.00-0.09 particles/gram and 3.4-4.6 particles/individual. The abundance of microplastics in the organs of each fish is quite varied, among others, in silver goatfish, the highest abundance is found in the gill organs, followed by the digestive tract and muscle; The highest abundance of mackerel scad, the largehead hairtail and yellowfin tuna was found in the muscle organ, followed by the gills and the lowest in the digestive tract organs. The abundance of microplastics in the organs varies considerably, presumably due to differences in organ function and the interaction of fish with water as a source of microplastics
