Abstract
Microalgae has functional group such as carboxylic (-COOH) and hydroxyl (-OH) which play an important role as adsorbent of heavy metal. Reduction of cadmium concentration by Oscillatoria microalgae in a culture medium has been carried out. This research aimed to study the ability of Oscillatoria microalgae as a biological adsorbent agent of cadmium heavy metal using BG-11 media. There were four treatments culture media with six repetitions consisting of P0 = 100 mL medium + 10,000 individual Oscillatoria; P1 = 1 mg/L Cd(II) + 100 mL medium + 10,000 individual Oscillatoria; P2 = 3 mg/L Cd(II) + 100 mL medium + 10,000 individual Oscillatoria; and P3 = 5 mg/L Cd(II) + 100 mL medium + 10,000 individual Oscillatoria. The result has shown the increasing of Oscillatoria in BG-11 culture media starting from day 4 to day 7 day was around 1208-1599 ind/L/day. P3 treatment which consist of 1 mg/L show the highest reduction of cadmium absorption with percentage of 24.05%, compared to the others.
