Mangroves of R. apiculata and A. marina have the ability and capability to absorb or bioaccumulate heavy metals.The purpose of this study was to determine and compare bioaccumulation of heavy metal Cd in A. marina and R. apiculata in the sediment and mangrove organ tissues.This research was conducted from March to August 2020 in the East Coast of Sumatra, Asahan Regency.Data analysis was carried out at the Aquaculture Study Program, Asahan University.The statistical analysis was performed using Principal Component Analysis (PCA) to examine the relationships and comparisons.The results showed that the Cd content in the mangrove sediment of A. marina was 0.05 ± 0 mg/kg) and R. apiculata was 0.03 ± 0 mg/kg.
