ABSTRACT
Diesel power plants produce wastewater containing heavy metals. This study focused on analyzing the role of mangroves around the site. The results showed that Cu metal concentrations in sediments ranged from 10.01–17.76 mg/kg and Cr ranged from 13.06–20.34 mg/kg, and Cu and Cr metal concentrations in Avicennia sp. mangrove were 25.04–42.05 mg/kg; 11.78–28.21 mg/kg, respectively, and showed bioaccumulation and translocation abilities of Cu and Cr of 2.34–2.5 (BCF > 1) and 0.63-0.69 (TF < 1); 0.9–1.39 (BCF < 1) and 0.4-0.53 (TF < 1), while in mangrove Rhizophora sp., namely 13.51–29.24 mg/kg; 21.52–58.38 mg/kg, and showed bioaccumulation and translocation abilities of Cu and Cr, respectively, 1.35–1.64 (BCF > 1) and 0.61-0.74 (TF < 1); 1.65-2.87 (BCF > 1) and 0.62-0.84 (TF < 1). BCF > 1 indicates that mangroves are accumulators, and BCF < 1 is an excluder. TF value < 1 indicates that mangroves are phytostabilisers. This research can be a reference for diesel power plant companies to plant mangroves Avicennia sp. and Rhizophora sp. around the source of wastewater outlets. In addition to absorbing CO2 emissions in the environment, they can also absorb heavy metals derived from diesel processing
