Abstract This research entitled “The Accumulation of Heavy Metals Kadmium (Cd) in water, sediments and aquaculture biota which contaminated by Batik waste in Mulyorejo village Pekalongan”. Purposes to know the heavy metal concentration Cd in water, sediment and bandeng’s flesh, relation between heavy metal concentration Cd in water and sediment with fish’s flesh, the pollution status in this aquaculture, and also the consumption properness from the aquaculture station. This study conducted by survey method with stratified random sampling on four stations with four replications. The data then analyzed by descriptive comparative, F-test, regression and correlation, Contamination Factor index, Geoaccumulation index and bioaccumulation factor. The result revealed that the heavy metal concentration in the water 0,003-0,009 mg/L, in sediments 1,272-2,208 mg/kg and fish’s flesh 0,087-0,168 mg/kg. The heavy metal concentration (Cd) in the water and sediments with fish’s flesh are have positive correlation which strongly (R=0,888 and R=0,906). The pollution status based on the contamination factor index (CF) categorized as very high contaminated and geoaccumulation index is mild contaminated (station III and IV) and mild to severe contaminated (station I and II). The fishes in this station are improper to be consumed except in station IV (distance ±300m from Bremi’s riveroutlet).
