Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)
Abstrak Telah dilakukan kajian sebaran logam berat Pb dan Co pada sedimen di Pesisir Pantai Way Kuala Bandar Lampung. Konsentrasi logam Pb dan Co ditentukan dengan menggunakan Spektrofotometer Serapan Atom (SSA). Hasil analisis menunjukkan konsentrasi logam Pb pada sedimen di Pesisir Pantai Way Kuala berada pada rentang 9,895 ± 0,873 ppm hingga 13,856 ± 1,168 ppm. Konsentrasi logam berat Co pada sampel sedimen berada pada rentang 8.241 ±1.517 ppm sampai 9.861±0.487 ppm. Nilai konsentrasi logam berat Pb dan Co yang diperoleh dalam penelitian masih dibawah nilai standar baku mutu logam berat pada sedimen yang telah ditetapkan oleh The Ontario Ministry Of The Environment. Validasi metode pada penentuan kadar Pb dan Co dalam sedimen menunjukan presisi dengan nilai RSD < 5 % dan nilai koefisien korelasi Pb dan Co masing-masing adalah 0,998 dan 0,990. Kata Kunci : Sebaran logam berat, Pb, Co , Pesisir Pantai Way Kuala Bandar Lampung Abstract Heavy metals distribution study was done for Pb and Co in Coastal sediment of Way Kuala Bandar Lampung. Pb and Co concentrations were determined by Atomic Absorption Spectrophotometer (AAS). The results of analysis showed concentrations of Pb are at the range 9,895 0,873 ppm up to 1,168 13,856 ppm. The concentrations of Co are at the range 8.241 1.517 ppm to 9.861 0.487 ppm. The value of the concentrations of Pb and Co are obtained in the research is still under the standard value of the raw quality of heavy metals in sediments that have been set by The Ontario Ministry Of The Environment. The validation method on determination of Pb and Co levels in sediments show precision with a value of RSD < 5% and the value of the correlation coefficient of Pb and Co respectively are 0,998 and 0,990. Keyword: distribution of heavy metals, Co, Pb, The Coastal of Way Kuala Bandar Lampung
