Abstract

Volcanic activities have infl uenced the Cisanggarung estuary in western Cirebon Regency, altering metal concentrations in the bottom sediment. Observation of metal content in the ocean there was carried out in August 2009. Sediment samples were collected at 16 stations along the Cisanggarung coastline. The aim of this work was to determine the spatial distribution of Cd, Cu, Pb and Zn in the sediment of the Cisanggarung estuary. Sediment was destructed using 3 acids: nitric acid, chloride acid and peroxide acid, which was then analyzed by Flame Atomic Absorption Spectrophotometry based on the US EPA 3050b method. The highest concentrations of Cd, Cu, Pb and Zn in the sediment were 0.73 mg/kg dry weight, 31.4 mg/kg dry weight, 23.9 mg/kg dry weight and 143 mg/kg dry weight, respectively. The metals in the sediment had accumulated near the shoreline, up to fi ve kilometers away from the river mouth, indicating that terrestrial area and sediment fractions infl uenced their distribution.

Abstract

Aktivitas perekonomian yang terus meningkat di wilayah pesisir utara Jawa, berpotensi menyumbangkan kontaminan antropogenik yang mengancam kualitas perairan pesisir dan estuari Cimanuk di Indramayu. Logam berat yang merupakan salah satu limbah dari aktifitas tersebut belum dipelajari secara terperinci. Penelitian ini bertujuan untuk menentukan distribusi dari logam Cu, Pb, Cd, Zn, dan Ni yang terlarut dalam air laut dan dalam sedimen di Estuari Cimanuk. Pengambilan sampel air laut dan sedimen dilakukan pada Bulan Mei 2017 di 18 stasiun. Sampel air laut diekstraksi menggunakan metode ektraksi balik (back extraction) sementara sampel sedimen diekstraksi menggunakan asam sesuai metode USEPA 3050B. Pengukuran logam berat dari ekstrak air laut ataupun sedimen dilakukan menggunakan Flame Absorption Spectrophotometry  berdasarkan metode USEPA 3050B. Distribusi spasial logam berat dalam air laut dan sedimen dimodelkan menggunakan ArcGIS® versi 10.6.1. Hasil penelitian menunjukkan konsentrasi logam terlarut dalam air laut untuk Cu, Pb, Cd, Zn, dan Ni adalah 0,0004 ? 0,0038 mg/L (Cu), <0,0001 ? 0,0044 mg/L (Pb), 0,0002 ? 0,0003 mg/L (Cd), 0,0005 ? 0,0119 mg/L (Zn), dan 0,0020 ? 0,0052 mg/L (Ni). Konsentrasi logam dalam sedimen adalah 12,36 ? 54,08 mg/kg (Cu), 6,43 ? 15,72 mg/kg (Pb), 0,07 ? 0,37 mg/kg (Cd), 64,53 ? 85,16 mg/kg (Zn), dan 19,66 ? 62,85 mg/kg (Ni). Model distribusi spasial menunjukkan bahwa logam berat dalam air laut maupun sedimen menunjukkan pola yang identik. Logam dengan konsentrasi tinggi umumnya terdeteksi di stasiun yang berlokasi dekat dengan daratan, mengindikasikan bahwa logam berat mengalami pengayaan yang berasal dari aktivitas antropogenik daratan.
