ABSTRACT
The study aimes to examine the accumulation level of selected heavy metal Cd in various of common
mud crab (Scylla spp.) samples from Segara Anakan Lagoon-Cilacap. Mangrove crab and sediment
samples were taken from Segara Anakan (108046’–109005’E; 7034’–7048’S) and were analyzed using
Atomic Absorption Spectrophotometer (AAS). The Cd extent in Scylla spp. varied from 0.084 - 0.273 ppm
which still below the European Commission (2006) threshold value (0.5 ppm). On the other hand Cd
concentration in sediment for most stations value (0.625 - 1.635 ppm) have exceeded the Interim marine
sediment quality guidelines (ISQGs value; 0.7 ppm) except for station 2 and 4. Concerning the sediment,
to interpret and assess the contamination status four indices were used, namely Contamination Factor
(CF), Enrichment Factor (EF), Pollution Load Index (PLI), and Geoaccumulation Index (Igeo). The results
show the Segara Anakan sediment value for CF varied 3.125 - 8.175, EF was 50.481, PLI was 5.381 and
Igeo varied 0.319 - 0.736. The finding result shows the Segara Anakan sediment could be considered as
moderately polluted.
