Abstract

Mikroplastik (MPs) merupakan bagian terkecil dari plastik yang telah terdegradasi melalui proses degradasi dan berpotensi untuk dicerna oleh organisme laut dalam proses mencari makan. Kehadiran MPs dalam daging ikan akan memiliki efek berbahaya baik pada ikan maupun manusia yang mengkonsumsinya. Penelitian ini bertujuan untuk mengidentifikasi karakteristik MPs pada daging ikan pelagis yaitu ikan tenggiri (Scomberomorus commerson) serta pada ikan demersal yaitu ikan kakap merah (Lutjanus malabaricus) yang didapatkan dari PPN Brondong, Lamongan. Pengamatan karakteristik visual meliputi bentuk, warna, ukuran dan kelimpahan MPs sedangkan jenis polimer diuji menggunakan FTIR. Uji Mann-Whitney (α = 0,05) dilakukan untuk menguji perbedaan kelimpahan MPs pada kedua spesies. Terdapat 301 partikel yang dihitung dan rata-rata kelimpahan MPs di S. commerson relatif lebih tinggi daripada di L. malabaricus. Bentuk MPs didominasi oleh fiber dibandingkan dengan fragmen dan pelet; ukuran yang paling umum adalah 100-500µm sedangkan warna yang paling umum adalah hitam, diikuti oleh merah, biru, kuning, hijau dan transparan. Secara kimia, cellophane adalah jenis polimer yang paling dominan dari MP. ===================================================================================================== Microplastic (MPs) is the smallest part of plastic that had been degraded through degradation process and having potential to be ingested by marine organism in the process of food foraging. The presence of MPs in the flesh of fish would have harmful effects on both the fish and human who consume it. This study purposed to identify the characteristics of MPs within the muscle of a pelagic fish, the Narrow-barred Spanish mackerel (Scomberomorus commerson) as well as in demersal species, the Red snapper (Lutjanus malabaricus) collected from PPN Brondong, Lamongan. Observed visual characteristics including the shape, color, size and abundance of the MPs while polymer type was tested using FTIR. A Mann-Whitney test (α = 0,05) was performed to test the difference of MPs abundance in both species. There are 301 particles counted and averaged abundance of MPs in S. commerson is relatively higher than in L. malabaricus. The shape dominated by fiber compared to fragment and pellet; the most common size is 100-500µm whilst the most common color is black, followed by red, blue, yellow, green and transparent. Chemically, cellophane is the most dominant polymer type of the MPs.
