“…This was demonstrated by the absence of inhibition of plant growth and no visible physical damage that showed symptoms of toxicity at all plants. A previous survey conducted on the aquatic areas around gold mining sites in West Java showed that these plants showing capability to accumulate mercury of more than 20 ppm in the root and shoot [14]. At harvest of 9 weeks the root and shoot dry weights produced by P.conjugatum was not significantly different from that of C.kyllingia, L.crustacea, D.radicosa, Z. purpureum and C.bicolor.…”

“…Root-exposed plants showed accumulation of mercury in the roots with movement to shoots by day ten [13]. A study conducted by Hidayati et al [14] indicated that various indigenous plant species, such as Paspalum sp., Cyperus sp., Caladium sp., Digitaria sp., Lindernia sp., and Zingiber sp., accumulated mercury of more than 20 mg kg-1 in the aquatic environment of ASGM areas of West Java. It is argued that those native species are potential for remediation of mercury-contaminated soils.…”

“…Semakin tinggi konsentrasi Hg yang terdapat dalam air, maka semakin tinggi jumlah Hg yang dapat diserap oleh tanaman (27,28) . Faktor genetik dan jenis tumbuhan dapat menjadi salah satu faktor dalam menentukan penyerapan logam pada zona perakaran dan akar/tajuk pada tingkat yang bervariasi (28,29) . Lebih tingginya tingkat reduksi Hg di bagian perakaran tanaman kemungkinan juga bisa disebabkan karena kinerja mikroba yang terkandung di media tanah dan kompos dalam sistem Lahan Basah Terpadu yang dipakai dalam penelitian ini.…”

“…Lebih tingginya tingkat reduksi Hg di bagian perakaran tanaman kemungkinan juga bisa disebabkan karena kinerja mikroba yang terkandung di media tanah dan kompos dalam sistem Lahan Basah Terpadu yang dipakai dalam penelitian ini. Diketahui dari berbagai hasil penelitian sebelumnya, ternyata bakteria rizosfer yang berada di perakaran tanaman mempunyai sifat mampu mereduksi Hg pula, selain logamlogam berat lainnya (29) . Beberapa jenis mikroba yang mampu mendegradasi Hg diketahui mempunyai enzim Hg reduktase, misalnya Pseudomonas putida, Geobacter metallireducens, Shewanella putrefaciens, Desulfovibrio desulfuricans, dan D. vulgaris (30) .…”

An integrated constructed wetland method was applied in this environmental remediation study to reduce the levels of mercury (Hg) Keywords: constructed wetland, mercury (Hg), artisanal gold mine, tailing ABSTRAKSuatu metode lahan basah buatan terpadu diterapkan pada penelitian remediasi lingkungan dengan menggunakan tanaman Phragmites australis dan mikroba pada kompos untuk mengurangi konsentrasi merkuri (Hg) pada air limbah. Air limbah yang digunakan pada penelitian terdiri dari limbah asli tambang emas rakyat Pongkor dengan konsentrasi 27 ppb dan limbah buatan dengan konsentrasi 30 ppb, 60 ppb dan 90 ppb. Hasil penelitian menunjukkan tingkat efisiensi penurunan konsentrasi Hg yang dihasilkan adalah sebesar 99,8% pada air limbah buatan dengan konsentrasi 60 ppb dan 90 ppb, serta sebesar 99,6% pada air limbah asli dan air limbah buatan konsentrasi 30 ppb. Tingkat akumulasi Hg tertinggi ditemukan di bagian akar tanaman dengan konsentrasi Hg total pada bagian akar, batang dan daun tanaman Phragmites australis adalah sebesar 3,502 mg/kg, 5,102 mg/kg dan 12,066 mg/kg pada air limbah buatan konsentrasi 30 ppb, 60 ppb dan 90 ppb. Lebih tingginya tingkat akumulasi Hg di bagian akar, dibandingkan dengan bagian lain dari tanaman, dapat menjadi suatu tanda bukti bahwa mikroba dari kompos yang menempel pada bagian akar tanaman itu juga ikut berperan dalam proses penyerapan Hg oleh tanaman.Kata kunci: lahan basah buatan, merkuri (Hg), tambang emas rakyat, tailing

“…Muddarisna et al (2013) reported that Digitaria radicosa, Cyperus kyllingia, and Lindernia crustacea potential are potential for use in phytoextraction mercury because these plant species efficiently absorb and transport mercury from the roots to the shoots. Hidayati et al (2009) reported several species of plants at ASGM locations in West Java that are able to accumulate mercury up to 20 mg/kg, i.e. Lindernia crustacea, Digitaria radicosa, and Cyperus kyllingia.…”

The discharge of small-scale gold mine tailing to agricultural lands at Pesanggaran village of Banyuwangi Regency caused soil degradation as indicated by reduced crop production. This soil degradation is mainly due to the toxicity of mercury contained in the tailing. The purpose of this study was to explore the potential of three local plant species, i.e. Lindernia crustacea, Digitaria radicosa, and Cyperus kyllingia for phytoremediation of agricultural land contaminated gold mine waste containing mercury, and its influence on the growth of maize. Six treatments (three plant species, and two levels of organic matter application) were arranged in a randomized block design with three replicates. Maize was grown on soil after phytoremediation for 8 weeks. The results showed that among the three plant species tested, Cyperus kyllingia was the potential candidate plant species for phytoremediation of soil contaminated with gold mine tailing containing mercury because of its ability to accumulate mercury from 32.06 to 73.90 mg / kg of soil in 60 days. Phytoremediation of mercury contaminated soil using Cyperus kyllingia using increased maize yield by 126% compared to that the biomass yield of maize grown on soil without phytoremediation. Induce phytoremediation needs to be carried out to accelerate the process of remediation of mercury contaminated soils.
