abstract: This study aims to determine the concentration of chromium contaminants in water and sediment and the accumulation level in Oreochromis niloticus and Clarias gariepinus cultivated in ponds downstream of Opak River, Indonesia. The observational method was used by measuring the bioaccumulation level in fish from different locations. Water, sediment, and fish samples were collected monthly from April to June 2022 to coincide with the dry season. The samples were collected randomly from cultivation ponds that received the Opak River flow in Banguntapan, Piyungan, Jetis, Pundong, and Kretek Sub-districts. Sampling and preparation of water, sediment, and fish samples were carried out. Cr concentration measurement in samples was performed using atomic absorption (AAS). The results showed that the O. niloticus and C. gariepinus cultivation ponds in the four study areas were contaminated with Cr, with the levels of 0.05 mg L-1 . The average concentration of Cr contaminants was consistently higher in pond sediment (1.084 mg kg-1 in O. niloticus ponds and 0.873 mg kg-1 in C. gariepinus ponds) than in pond water (0.207 mg L-1 in O. niloticus ponds and 0.132 mg L-1 in C. gariepinus ponds). O. niloticus and C. gariepinus samples from the four study areas were contaminated and accumulated Cr contaminants with a range and mean of 0.188-0.330 and 0.257 for O. niloticus and 0.191-0.516 and 0.278 for C. gariepinus. Compared to O. niloticus, C. gariepinus had a higher accumulation, but the levels in both species were below the safe limit for food, namely 2.5 mg kg-1 . The concentration of Cr contaminants in water samples was not significantly different between the control and treatment ponds (p0.05). The range of Cr bioaccumulation factor (BAF) in C. gariepinus was higher (0.251-0.411) compared to O. niloticus (0.184-0.388).
