Abstract

Pencemaran lingkungan di perairan laut yang diakibatkan sampah plastik menjadi permasalahan yang ramai dibicarakan beberapa tahun terakhir Partikel plastik dengan ukuran antara >1 μm dan <5 mm disebut dengan mikroplastik. Teripang sebagai deposit feeder, sangat rentan menelan mikroplastik yang terakumulasi pada sedimen. Karena hal tersebut maka teripang berpotensi sebagai spesies indikator pencemaran mikroplastik di perairan laut. Tujuan penelitian ini yaitu untuk mengetahui karakteristik fisik dan kimia mikroplastik yang terdapat pada teripang (Paracaudina australis), air dan sedimen di Perairan Pesisir Timur Surabaya dan mengetahui potensi teripang sebagai bioindikator pencemaran mikroplastik di Perairan Pesisir Timur Surabaya. Identifikasi karakteristik mikroplastik dilakukan dengan menggunakan mikroskop stereo dengan bantuan optilab viewer dan karakter kimia polimer mikroplastik dengan menggunakan ATR-FTIR. Total partikel mikroplastik pada teripang sebanyak 551 partikel, pada air sebanyak 65 partikel dan pada sedimen sebanyak 78 partikel. Rata- rata kelimpahan mikroplastik pada teripang sebesar 4,30 partikel/g, pada air sebesar 2,96 partikel/m3 dan pada sedimen sebesar 390 partikel/kg. Ukuran mikroplastik pada teripang paling banyak ditemukan pada rentang ukuran 51-75 μm sejumlah 118 partikel (21,4%), pada air paling banyak ditemukan pada rentang ukuran 101-250 μm sebanyak 22 partikel (33,8%), dan pada sedimen paling banyak ditemukan pada rentang ukuran 101-250 μm sebanyak 27 partikel(34,6%). Bentuk mikroplastik yang paling mendominasi yaitu fragmen dan fiber dengan warna yang mendominasi yaitu biru dan hitam. Polimer yang didapatkan dari hasil FTIR pada teripang, air dan sedimen yaitu Cellophane (CP). Potensi teripang sebagai bioindikator pencemaran mikroplastik dengan uji korelasi Spearman menyatakan nilai korelasi sebesar 0,4 yang tergolong dalam kategori cukup kuat. Potensi teripang sebagai bioindikator berkaitan dengan habitat, kebiasaan mencari makan/ deposit feeder serta hewan dengan pergerakan lambat/ semi mobile.

Environmental pollution in marine waters caused by plastic waste has become a problem that has been discussed in recent years. Plastic particles with sizes between >1 m and <5 mm are called microplastics. Sea cucumbers as deposit feeders are very susceptible to ingesting microplastics that accumulate in sediments. Because of this, sea cucumbers have the potential as an indicator species of microplastic pollution in marine waters. The purpose of this study was to determine the physical and chemical characteristics of microplastics found in sea cucumbers (Paracaudina australis), water and sediment in the East Coast of Surabaya and to determine the potential of sea cucumbers as bioindicators of microplastic pollution in the East Coast of Surabaya. Identification of microplastic characteristics was carried out using a stereo microscope with the help of an optilab viewer and the chemical characteristics of microplastic polymers using ATR-FTIR. The total microplastic particles in sea cucumbers are 551 particles, 65 particles in water and 78 particles in sediment. The average abundance of microplastics in sea cucumbers is 4.30 particles/g, 2.96 particles/m3 in water and 390 particles/kg in sediments. The size of microplastic in sea cucumbers was most commonly found in the size range of 51-75 m with 118 particles (21.4%), in water the most found in the size range of 101-250 m with 22 particles (33.8%), and in sediment the most found in the size range 101-250 m as many as 27 particles (34.6%). The most dominant forms of microplastics are fragments and fibers with the dominant colors being blue and black. The polymer obtained from the FTIR results in sea cucumbers, water and sediment is Cellophane (CP). The potential of sea cucumbers as a bioindicator of microplastic pollution with the Spearman correlation test stated that the correlation value was 0.4 which was categorized as strong enough. The potential of sea cucumbers as bioindicators is related to habitat, foraging habits/deposit feeders and animals with slow/semi-mobile movements.
