Abstract

Penelitian ini bertujuan untuk menganalisis kandungan dan tingkat pencemaran logam berat Hg dan Cd dalam air, sedimen dan kerang darah (Anadara granossa) di perairan Morodemak, Banjir Kanal Timur dan Mangkang Semarang. Penelitian ini dilaksanakan pada bulan Agustus 2004-Januari 2005 dengan metode penelitian yang digunakan adalah Analisis Pengaktifan Neutron (APN). Hasil penelitian kandungan logam berat Hg dan Cd pada ketiga lokasi menunjukkan pola akumulasi yang cenderung sama di stasiun muara dan laut, baik pengamatan dalam sedimen maupun air. Kandungan logam berat Hg dan Cd pada kerang Anadara granosa menunjukkan nilai yang bervariasi, namun cenderung dipengaruhi sedimen dan air pada dua media tersebut, terkait dengan sifatnya yang filter feeder dan sessil. Meskipun demikian variasi faktor lingkungan seperti suhu, salinitas, pH, kecepatan arus dan jenis sedimen juga memberikan kontribusi yang cukup penting. Kandungan logam berat Hg dan Cd dalam kolom air di Morodemak, Banjir Kanal Timur dan Mangkang telah melampaui batas yang diperbolehkan, demikian pula kandungan berat Hg pada kerang darah  sudah melampaui baku mutu yang ditetapkan. Kata kunci : Hg, Cd, Air, Sedimen, Anadara granossa,metode APN  The aims of the research is to analyze the heavy metals concentrations and the pollution level of Hg and Cd in water, sediment and blood mussels (Anadara granossa) at Morodemak, Banjir Kanal Timur and Mangkang Rivers. This research was conducted from August 2004 to January 2005 using The Neutron Activation Analysis Method. The results showed that the heavy metals concentrations of Hg and Cd  in water and sediment tend to show similar accumulation patern both on estuary and the sea. While the heavy metals concentrations of Hg and Cd in blood mussels (Anadara granossa) show a variated value, which was influenced by the environmental conditions, due to the their behaviour as filter feeder and sesille. The environmental factors such as temperature, salinity, pH, current dan sediment type also play an important role and contributed significantly to the heavy metals accumulation. The concentrations of Hg and Cd in water at the  Morodemak, Banjir Kanal Timur dan Mangkang was higher than standard quality, so does  the Hg concentration in blood mussels.

Abstract

Abstrak Nitrat sangatlah penting bagi kehidupan fitoplankton di laut, sehingga diperlukan kajian tentang sebaran nitrat. Penyebaran nitrat ini dipengaruhi beberapa faktor baik secara lansung dan tidak langsung. Secara langsung penyebaran nitrat dipengaruhi oleh arus pasang surut dan secara tidak langsug dipengaruhi oleh faktor fisika kimia oseanografi, yaitu suhu, salinitas, dan pH. Penelitian ini dilakukan di Perairan Tugu Semarang pada tanggal 1 Maret 2012. Lokasi pengambilan sampel dibagi menjadi 6 stasiun yang dapat mewakili persebaran nitrat di perairan tersebut. Penelitian ini bertujuan untuk mengetahui kandungan nitrat  di perairan Tugu, Semarang dan mengetahui sebaran nitrat yang dipengaruhi faktor hidro oseanografi. Metode yang digunakandalampengambilan sampel air laut adalahpurposive sampling method. Hasil penelitian di perairan Tugu Semarang menunjukkan bahwa tipe pasang surut yang terjadi adalah campuran condong ke harian tunggal. Konsentrasi nitrat ketika surut berkisar 0,288 - 0,342 mg/L, dan ketika pasang 0,283 - 0,337 mg/L. Persebaran nitrat yang terjadi saat surut lebih tinggi konsentrasinya dibanding pada saat pasang. Arus tidak terlalu mempengaruhi pola sebaran nitrat, tetapi penurunan konsentrasi nitrat diakibatkan adanya pengenceran.
