Abstract

Penelitian ini bertujuan menganalisis pengaruh pengasaman laut terhadap toksisitas logam Pb denganmenggunakan biomarker imunitas kerang hijau (Perna viridis). Penelitian dilaksanakan pada bulan April hinggaMei 2017 di Laboratorium Penangkaran dan Rehabilitasi Ekosistem Laut Fakultas Ilmu Kelautan danPerikanan, 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 berpengaruhsignifikan (p<0.05) terhadap hemosit kerang yaitu persentase jumlah basofil, eosinofil dan hemosit mati.

Abstract

Plastics become debris in the ocean that can be broken down into tiny particles of micro size (<5 mm) and scattered into columns to the bottom of the water. Its very small size makes it easily accessible to various aquatic organisms, such as plankton, crustacean, and mussel. There have been many studies use mussel as a bioindicator for microplastic pollution but no one has observed the effect of microplastic exposure to mussel mortality. The aim of study was to examine the effect of microplastic on mussel mortality. Green mussels were collected from Mandalle Waters, Pangkep Regency (Pangkajene Kepualauan) then were exposed to microplastic polyethylene originating from shieving of scrub soap. The exposure was carried out for 7 days with microplastic concentrations of 0.05 (A), 0.5 (B), and 5 (C) g/L. Statistical test results showed the treatment B and C were not significantly different, but the two treatment were significantly different from treatment A. The percentage of green mussel mortality during the experiment increased with increasing microplastic concentrations with the percentage of mortality exceeding 80% at treatment C.

Abstract

Study on several metals in Lake Hasanuddin University (Unhas) has been conducted as a basis of management of the lake as an aquaculture activity. This study was performed by sampling of water, sediment and biota, such as fish.  The results revealed that the average of temperature 32.72 oC has exceeded the threshold of the quality standard.  The average of dissolved oxygen, ammonia, pH were 5.8 mg/l, 0.016 mg/l, and 7.72 respectively.  Consentrations of nitrate and phosphate were 0.39 and 0.28 mg / l, respectively. Concentrations of mercury (Hg), cadmium (Cd) and cobalts (Co) were not detected in water coloumn.  Arsenic (As) was detected in level that still allowed by the threshold of the quality standard.  Concentrations of chromium (Cr) and plumbum (Pb) have exceeded the threshold of the quality standard.  In sediment, Hg and As were not detected, but Cr was detected in level that not exceed the the threshold of the quality standard.  Conccentrations of Cd, Co and Pb detected exceed the threshold of the quality standard.  Silver barb (Barbonymus gonionotus) that live in the lake has been contaminated by As, Cd and Pb. Keywords: Lake Unhas, metals, aquaculture, Silver barb.
