Maninjau Lake has decreased water quality for their activities outside and inside the lake which can cause pollution, one of which is water pollution by heavy metals. This study aims to assess the heavy metal content in tilapia nilotica, water hyacinth and sediment in the fish cage culture area at Maninjau Lake using Flame Absorption Atomic Spectrometry (FAAS). The results showed: (1) Tilapia nilotica has a Pb(II) concentration of 0.6-4.3 mg/kg and Cu(II) 0.7-5.6 mg/kg; (2) Water hyacinth has a Pb(II) concentrations of 3.1-7.6 mg/kg and Cu(II) 7.1-18.5 mg/kg; and (3) Sediment has a Pb(II) concentrations of 6.6-11.9 mg/kg and Cu(II) 10.6-46.1 mg/kg. The concentration of Cd(II) in all samples was not detected, while Pb(II) and Cu(II) has passed the maximum threshold.
