They will be deposited and accumulated in the bed sediments and potentially to cause contamination in the waters as well. The study was conducted to investigate vertical profiles of heavy metals Cu, Ni, and Mn based on sediment depth and the correlation between the concentration of heavy metals and the grain size of sediments. Coring method was used for sampling the sediments at 1-3 cm, 4-6 cm and 7-9 cm of depths. Samples were analyzed using AAS method to determine Cu, Ni, and Mn concentrations. Sieving and pipetting methods were used to determine the grain size of the sediments. The results showed that the average concentration of heavy metals Cu, Ni, and Mn in the top layer was 7.74 ppm; 8.17 ppm; 1345.03 ppm. The middle layer was 6.91 ppm; 7.48 ppm; 1279.35 ppm. The bottom layer was 7.36 ppm; 7.79 ppm; 1413.66 ppm. The concentration of Cu heavy metal had a positive correlation with the sand fraction, while the heavy metals Ni and Mn had a positive correlation with the mud fraction.

Logam berat tersebut akan mengendap dan terakumulasi di sedimen dasar perairan dan berpotensi menimbulkan pencemaran perairan. Penelitian ini bertujuan untuk mengetahui profil logam berat Tembaga, Nikel, dan Mangan secara vertikal berdasarkan kedalaman sedimen dan korelasi antara konsentrasi logam berat dengan ukuran butir sedimen. Pengambilan sampel sedimen dilakukan menggunakan metode coring untuk kedalaman 1-3 cm, 4-6 cm, dan 7-9 cm.
