Daftar Isi:
- Telah dilakukan kajian kandungan logam berat Cd, Cr, dan Hg pada sampel sedimen yang diperoleh dari Pesisir Teluk Lampung. Tujuan dari penelitian ini adalah mengukur kadar dan tingkat pencemaran logam berat Cd, Cr, dan Hg, yang ada pada sedimen di perairan pesisir Pesawaran. Terdapat 3 spot lokasi pengambilan sampel (Pulau Lunik, Kekatang, dan Muara Sanggi) dan diambil di hari yang sama serta diberi label sebagai penanda lokasi tempat sampel diambil. Preparasi sampel logam berat dilakukan dengan metode destruksi basah dan dianalisis secara Spektrofotometer Serapan Atom (SSA). Hasil pengukuran menunjukkan kandungan rerata logam Cd berkisar 4,6789 ppm - 5,9379 ppm, kandungan rerata logam Cr berkisar 10,2267 ppm - 11,9628 ppm, dan kandungan rerata logam Hg berkisar 1,0167 ppm - 1,6591 ppm. Hasil pengukuran pada sampel logam Cd dan Hg menunjukkan bahwa kadarnya sudah melewati batas baku mutu, sedangkan pada sampel logam Cr menunjukkan M. Firza Ersa bahwa kadarnya belum melewati batas baku mutu menurut National Sediment Quality Survey : Second Edition, U.S Environmental Protection Agency (USEPA). _________ Kata Kunci : Logam Berat, Sampel Sedimen, SSA, Pesisir Teluk Lampung. abstract The heavy metal’s study of Cd, Cr, and Hg have done of sediment sample which obtained at Lampung coastal bay. Aim of this research are measure the content and pollution level of Cd, Cr, and Hg’s heavy metals in Pesawaran coastal waters. There are 3 sampling location spots (Lunik Island, Kekatang, and Estuary of Sanggi) and taken on the same day and labeled as location where the sample was obtained. Sample preparation of heavy metal were did with wet destruction method and analyzed by Atomic Absorption Spectrophotometer (AAS). The measurement results show the average content of Cd metal is 4.6789 ppm - 5.9379 ppm, the average content of Cr metal is 10.2267 ppm - 11.9628 ppm, and the average content of Hg metal is 1.0167 ppm - 1.6591 ppm. The measurement results in Cd and Hg metal samples show that the levels have exceeded the quality standard, whereas Cr metal samples indicate that the levels M. Firza Ersa have not exceeded the quality standard according to the National Sediment Quality Survey: Second Edition, U.S Environmental Protection Agency (USEPA). _____ Key Word : Heavy Metal, Sediment Sample, AAS, Lampung Coastal Bay
