Abstract

Mangrove vegetation has a wide range of distribution on the Indonesian coast, including Pemangkat, Sambas Regency, and West Kalimantan. Near this area, there are various activities, such as industrial, fishing, and shipping which are possible sources of heavy metal pollution. Water pollution caused by heavy metals is one of the serious problems. This condition can reduce water quality and has an impact on aquatic organisms. Monitoring of water quality needs to be done to reduce health problems and maintain the stability of aquatic ecosystems. Mudskipper (Boleophthalmus sp.) can be used as a bioindicator due to its ability to accumulate heavy metals from the environment, especially in mangrove areas. Heavy metal such as cadmium (Cd) is difficult to decompose and toxic to the environment and biota. This heavy metal pollution may originate from port and fisheries activities. The aim of this study was to determine the Cd content in the Mudskipper, waters, and sediment samples. Sampling was carried out at two stations. Analysis of the Cd content was done using Atomic Absorption Spectrophotometry (AAS). The result showed that concentrations of Cd in the waters and sediment samples were above the threshold. Meanwhile, the Cd level in Mudskipper flesh was still below the maximum limit. Keywords: heavy metal, cadmium (Cd), mudskipper, Pemangkat, West Kalimantan

Abstract

Pemangkat is a coastal area in Sambas Regency which has a mangrove ecosystem. One of the biota found in mangrove forest areas is the Giant Mudskipper. This fish is often used as an environmental bioindicator due to its characteristics of living in the intertidal zone and being able to absorb and accumulate metals. Heavy metal pollution in marine and coastal areas has become a global problem that causes negative impacts on ecosystems, biota, and human health. One of the heavy metals that can pollute waters due to fishing and port activities is lead (Pb). Pemangkat is one of the centers of capture fisheries activities in West Kalimantan. Therefore, this research aims to analyze the content of the heavy metal of Pb in water, sediment, and Mudskipper in the Pemangkat mangrove ecosystem, Sambas, West Kalimantan. The Pb content in water, sediment, and Giant mud skipper samples was analyzed using an Atomic Absorption Spectrophotometer (AAS) at a wavelength of 283.3 nm. Accumulation of heavy metal in the biota was determined by the bioconcentration factor (BCF). The concentration of lead metal (Pb) in water and sediment samples was highest at Station II, such as 0.40 mg/L and 0.25 mg/L respectively. The metal content of Pb in Giant Mudskipper was highest at Station I (0.224 mg/kg). The BCF values for Giant Mudskipper at Stations I and II were 1.18 and 0.86. Keywords: Lead (Pb), Mangrove, Mudskipper, Boleopthalmus. Abstrak Pemangkat merupakan wilayah pesisir di Kabupaten Sambas yang memiliki ekosistem mangrove. Salah satu biota yang hanya ditemukan di daerah hutan mangrove adalah ikan tembakul.
