Abstract

Sea pollution can be caused by various sources, one of the biggest sources of marine pollution is anthropogenic activities. Types of pollutants that are often found in pollution are heavy metal content in sea water and oil spills resulting from transportation activities. Both types of pollutants will survive for a long time and can enter the food chain. Therefore, we need an Eco-friendly solution for the purpose of the problem. Bioremediation techniques using microalgae Chaetoceros calcitrans and Skeletonema costatum are the right solution. This study compares the quality of these microalgae in degrading heavy metal Cd and diesel oil on a laboratory scale. The concentration of heavy metal test was 0.7, 1.3 and 1.9 ppm, while the amount of diesel oil was 5, 10, and 20 mL. Showing the two microalgae that can degrade all test pollutants with different percentages of degradation.
