Cadmium metal is dangerous for green mussel organisms because it can interfere with fertility. Green mussels are organisms widely distributed, can survive in poor environments, and sedentary organisms. Green shellfish is a filter feeder and is used as a bioindicator to monitor the concentration of Cd metal in the waters. The research objective was to measure the concentration of Cd metal in sea water, sediment, and green mussel meat in the waters of Tambak Lorok and Morosari. The Cd metal contents of seawater, sediments, and green mussels were measured using Atomic Absorption Spectrophotometer. The results showed that Cd metal concentrations in seawater in May, July, and August 2018 in Tambak Lorok and Morosari waters were below the detection limit (0.001mg/L); 0.002 mg/L; and 0.002 mg/L, respectively. The concentrations of cadmium in sediment in May, July, and August in Tambak Lorok waters were below the detection limit (0.004 mg/kg); 0.0023 mg/kg; and 0.0021 mg/kg, respectively, and in Morosari waters were below the detection limit (0.004 mg/kg); 0.002 mg/kg; and 0.0114 mg/kg, respectively. Cd metal concentrations in green mussel meats in May, July, and August in Tambak Lorok waters were below the detection limit (0.01mg/kg); 0.0060; and 0.1277 mg/kg, respectively, and in Morosari water were below the detection limit (0.01mg/kg); 0.0067 mg/kg; and 0.0493 mg/kg, respectively. Cd metal concentrations in sea water and green mussels in the waters of Tambak Lorok and Morosari were below the quality standard and the concentrations of Cd metal in seawater, sediments, and green mussel meat in the waters of Tambak Lorok and Morosari were not significantly different.   Keywords: cadmium, green mussels, morosari, seawater, sediments, Tambak Lorok

Konsentrasi logam berat memiliki korelasi positif terhadap fraksi silt dan clay.  Distribusi logam berat di lokasi penelitian berasosiasi kuat terhadap fraksi ukuran butir halus dan bahan organik, melalui proses adsorpsi. The waters of the Muara Sungai Tiram, Marunda, North Jakarta, are areas that are surrounded by very dense industrial activities. The existence of these activities has an impact on the concentration of heavy metals in basic sediments in these waters. The purpose of this study was to determine the concentration of heavy metals in basic sediments and determine the correlation between the concentration of heavy metals with grain size on the base sediment in the liquid and the correlation between the concentration of heavy metals with organic matter. Analysis of heavy metal concentrations was carried out using the acid destruction method, then the concentration was read using the Atomic Absorption Spectrophotometer (AAS), and processed into a heavy metal concentration map using Arcgis 10.3. Based on these studies the value of heavy metal concentrations obtained in the range of 20.19 - 55.681 ppm. Heavy metal concentrations have a positive correlation with the mud and organic matter fractions with r values of 0.68 and 0.10, respectively. The distribution of heavy metals in this study is strongly associated with the fine grain size fraction and organic matter, through the adsorption process

Contamination of Copper in Mugil dussumeri (Actinopterygii: Mugilidae, Forsskål, 1775) which was caught in Semarang waters, Indonesia The marine environment in Semarang waters are highly polluted by heavy metals such as copper (Cu).  On the other side, these areas have become producers of fishery commodities such as mullet fish Mugil dussumieri. The aims of this study was to determine the heavy metal content of Cu in mullet fish during wet monsoon (December 2017 and February 2018). Atomic Absorption Spectrophotometer were used to analysis of Cu concentration in marine water and fish meat.  The results show that the Cu content in marine water was not detected while in the meat of mullet fish during December 2017 and February 2018 were 0.66 ± 0.07 mg/kg and 0,604 ± 0.217 mg/kg, respectively. The results were still within the quality standard for maximum limit of Cu content allowed in seafood by FAO/WHO. Lingkungan perairan laut di sekitar Semarang berpeluang sangat tinggi untuk terpolusi logam berat tembaga.  Di lain sisi perairan ini menjadi daerah produksi perikanan seperti ikan belanak Mugil dussumieri. Tujuan dari penelitian ini adalah untuk mengetahui kandungan logam Cu dalam daging ikan belanak yang ditangkap selama musim penghujan (Desember 2017 dan Februari 2018). Untuk mengetahui konsentrasi Cu dalam air laut dan ikan belanak digunakan Atomic Absorption Spectrophotometer.  Hasil penelitian menunjukkan bahwa konsentrasi logam Cu selama bulan Desember 2017 adalah 0.66 ± 0.07/kg dan selama bulan Februari 0,604 ± 0.217 mg/kg, sedangkan konsentrasi Cu dalam air laut tidak terdeteksi.  Hasil penelitian dapat disimpulkan bahwa kandungan Cu dalam ikan belanak masih berada pada konsentrasi yang diperbolehkan oleh FAO/WHO.
