Water pollution is the event of the entry of substances that are toxic in nature which later can reduce the quality of water that is in a waters. The presence of too many heavy metals Pb and Cd in the waters can cause threatened ecosystems in a waters. Heavy metals of this type enter a lot of water due to sea transportation activities such as diesel oil, industry and coastal community activities. Many studies suggest that Eucheuma cottonii seaweed species is effective in absorbing heavy metals Pb and Cd, therefore further research is needed regarding the effectiveness of Eucheuma cottonii seaweed species in absorbing differences in Pb and Cd heavy metals. The purpose of this study was to determine the ability of phytoremediation of Pb and Cd using seaweed species Eucheuma cottonii. The method used in this study is the experimental method using a Completely Randomized Design (CRD). The procedure of this study included sample preparation, treatment and observation of water quality (temperature, salinity, pH and DO) for 10 days, and testing of heavy metal content in water and seaweed at the beginning and end of the study. The t-test results of environmental parameters on the degradation of Pb and Cd heavy metals with a confidence interval of 95% indicate that Temperature and DO do not have a significant difference but vice versa in the pH and Salinity data.
