PENGGUNAAN IMUNITAS KERANG HIJAU (Perna viridis) SEBAGAI BIOMARKER UNTUK MENDETEKSI PENGARUH PENGASAMAN LAUT TERHADAP TOKSISITAS LOGAM Pb
Abstract
Penelitian ini bertujuan menganalisis pengaruh pengasaman laut terhadap toksisitas logam Pb dengan
menggunakan biomarker imunitas kerang hijau (Perna viridis). Penelitian dilaksanakan pada bulan April hingga
Mei 2017 di Laboratorium Penangkaran dan Rehabilitasi Ekosistem Laut Fakultas Ilmu Kelautan dan
Perikanan, Universitas Hasanuddin. Metode yang digunakan dalam penelitian ini adalah rancangan faktorial.
Kerang hijau dengan ukuran panjang 5-6 cm diberi perlakuan dengan paparan konsentrasi logam Pb 0 mg/l
(kontrol), 0.008 mg/l, 0.08 mg/l, 0.8 mg/l, pada kondisi pH (level asidifikasi) air media hidup yaitu 6.2, 7.7, 8.2.
Pemaparan dilakukan selama 96 jam. Hasil penelitian menunjukkan bahwa logam Pb dan pH berpengaruh
signifikan (p<0.05) terhadap hemosit kerang yaitu persentase jumlah basofil, eosinofil dan hemosit mati.
