Abstract

This research entitled "Accumulation of Chromium (Cr) Heavy Metal in Water Sediment and Mullet Fish (Mugil sp.) In the Donan River Segara Anakan Cilacap". This study aims to determine the content of Cr heavy metals in water media, sediment and mullet fish, the relationship between Cr heavy metal content in water with sediment and mullet fish, pollution status in the Donan River Segara Anakan Cilacap. Survey method used in this research with Purposive Random Sampling technique on four stations with four replications. Data were analyzed using comparative descriptive, F test, regression and correlation, Contaminant Factor (CF), Geoaccumulation Index (Igeo) and Bioaccumulation Index (BAF). The results showed the Cr metal content in water was 0.0112-0.0271 mg/L, the sediment was 0.4430-0.82267 mg/kg, the mullet fish was 0.1283-0.3320 mg/kg. The correlation of Cr metal in the water with sediments and mullets also showed positive result, strongly related (R = 784) and moderate (R = 634). Pollution status based on CF index (all stations) is categorized as low contamination (CF <1), Igeo (all stations) categorized as lightly polluted and BAF is categorized of organisms that have the ability to accumulate metals in the body from all station.
