Heavy metals are widely known pollutants with a bioaccumulative nature that can be transferred and accumulated in biota, such as mullet fish (Mugil sp.). The heavy metals Cd and Cu have different anthropogenic and natural sources. Heavy metals can potentially absorb existing biota, such as mullet fish. Fish absorb metals from the water in the body through gills, skin surfaces, and food. This study aims to identify Cd and Cu metals in distributed water, sediment, and mullet fish in the Plawangan Timur, Segara Anakan lagoon, Cilacap, Central Java, and the relationship between aquatic media and sediment and mullet fish. The study used a research method with a targeted random sampling method at five stations with four replications. The survey was conducted from April to September 2022. The data obtained were analyzed descriptively using the ANOVA test, including F-test, regression, and correlation. The results showed that the Cd and Cu content in water, sediment, and mullet fish showed variation values between stations. The correlation between the Cd and Cu metals in water, sediment, and mullet fish showed a positive correlation with moderate to strong proximity. The content of heavy metal Cd in mullet fish media in Plawangan Timur Segara Anakan Cilacap has exceeded the specified quality standard based on the national standard of water quality, while heavy metal Cu in mullet fish is still below the specified quality standard namely 0.01 mg/dm3.
