Penelitian ini bertujuan untuk menganalisis kandungan logam berat Hg pada media air, sedimen, akar, batang, dan daun mangrove  serta menganalisis kemampuan Avicennia marina dan Rhizophora apiculata dalam mengakumulasi dan mentranslokasi logam berat Hg tersebut. Penelitian dilakukan di Sungai Donan, Cilacap.  Teknik pengambilan sampel dilakukan secara cluster dengan Purposive Sampling pada 4 stasiun dengan 3 kali ulangan. Hasil analisa kandungan logam berat Hg di media air berkisar antara 0,007 – 0,026 mg/L, di sedimen berkisar antara 0,114 – 0,161 mg/Kg, pada mangrove Avicennia marina bagian akar berkisar antara 0,025 – 0,071 mg/Kg, batang berkisar 0,020 – 0,056 mg/Kg, daun berkisar 0,012 – 0,019 mg/Kg dan pada mangrove Rhizophora apiculata  bagian akar berkisar antara 0,026 – 0,060 mg/Kg, batang berkisar 0,015 – 0,026 mg/Kg dan daun berkisar 0,010 – 0,021 mg/Kg. Menurut perhitungan BAF (Bioaccumulation Factor) dan TF (Translocation Factor), kedua jenis mangrove (Avicennia marina dan Rhizophora apiculata) relatif tidak mampu dalam mengakumulasi dan mentranslokasi logam berat Hg di tubuhnya, nilai BAF berkisar antara 0,343 – 1,055 dan nilai TF berkisar antara 0,597 – 1,333.

This research aimed to analysis accumulation Hg in water, sediment, roots, stems, and leaves mangroves and to analysis the ability of Avicennia marina and Rhizophora apiculata to accumulate and translocate heavy metal Hg. The sampling technique used cluster with purposive sampling at 4 stations with 3 replications. The results showed that the concentration of Hg in water had ranges   0.007 - 0.026 mg / L, Hg in sediments ranged  0.114 - 0.161 mg / Kg.  The potential accumulation of mangrove vegetation showed that the Avicennia marina roots had  range 0.025 - 0.071 mg / Kg, stems ranged 0.020 - 0.056 mg / Kg, leaves ranged  0.012 - 0.019 mg / Kg. However Rhizophora apiculata roots had Hg accumulation between 0.026 - 0.060 mg / Kg, stems ranged from 0.015 - 0.026 mg / Kg and leaves ranged from 0.010 - 0.021 mg / Kg.  Based on value of BAF (Bioaccumulation Factor) and TF (Translocation Factor) showed that Avicennia marina and Rhizophora apiculata had ability to  accumulate and transclocate  heavy metal Hg in their bodies with scores were  BAF values ranged  0.343 - 1.055 and TF values ranged  0.597 - 1,333.
