Abstract

Small-scale gold mining activities in Sekotong District of West Lombok Regency started in 2009. Gold is recovered through a two-stage process of amalgamation and cyanidation. Tailing is discharged to land with no concern for contaminants. Phytoremediation could cost-effectively replace traditional mercury remediation strategies. The objective of this study was to elucidate the potential of Cyperus kyllingia Endl for phytoremediation of soil contaminated with mercury of gold amalgamation and cyanidation tailings in conjunction with ammonium thiosulphate to phytoextract mercury. The study was conducted at the Laboratory of Soil Brawijaya University and in a shade house located in the area of ​​Dermo, Sengkaling. Samples of tailings-uncontaminated soil were mixed with samples of tailings with the proportion of 30%: 70% (w/w). At harvest shoots and roots were analyzed for mercury concentration in treatments, Tailing (tailings cyanidation and amalgamation), ligand ( 0, 4, and 8 g/kg ). The results showed that Cyperus kyllingia was a potential local species for phytoremediation of mercury contaminated soils as this plant was able to take up mercury of 122,53 mg/kg (shoot) and 77,9 mg/kg (shoot). Based on TF (translocation factor) value that was < 1, it is a potential species for phytostabilization. Addition on 8 g ammonium thiosulphate / kg planting media enhanced mercury taken up by plant as much as 71,18%. Key words: mercury , phytoremediation, ligand

Abstract

Tailings, waste material from gold processing, contain heavy metals that are toxic such as mercury (Hg). One of the negative impacts is causing contamination of soil, developed through the accumulation of heavy metals. Phytoremediation is an alternative technology, using plant to clean heavy metal contaminated soil. A research, using Caladium bicolor, Paspalum conjugatum and Commelina nudiflora was then conducted as phytoremediation for contaminated soil. The research was conducted in the greenhouse using a randomized block design (RBD) with 3 factors and 3 replications. The first factor was percentage of tailings in the soil (10% and 20%). The second factor was the type of phytoectractor plants (C. bicolor, P. conjugatum and C. nudiflora). The third factor was the use of organic matter (with and without organic matter). The study was conducted in two steps, namely 1) phytoremediation, using C. bicolor, P. conjugatum, and C. nudiflora; 2) evalution of corn growth after phytoremediation. The results showed that Hg content in the soil containing 10% tailings (T1) was twice less than in the soil containing 20% tailings (T2). The addition of organic matter increased the potential for Hg absorption and consequently reduced content of Hg in the soil. C. bicolor, P. conjugatum and C. nudiflora decreased Hg content in the soil, and hence potentially used for phytoremediation. Of the three plants, C. nudiflora showed the highest Hg absorption. Decreasing content of Hg in the soil improved corn growth, as indicated by increasing height, number of leavs and dry weight.Keyword: Mercury (Hg), Hyperacumulator, Phytoremediation

Abstract

Levels of heavy metals in agricultural land can be reduced and neutralized with an inexpensive method, known as phytoremediation. The purpose of this study was to learn and know the ability Lindernia crustaceans, Digitaria radicosa, and Cyperus rotundus as fitoremediator for soil contaminated by gold mining waste containing mercury and its effects on growth and yield of maize The study was conducted in a glasshouse with sixteen treatments consisted of three plant accumulators, two soils contaminated with mercury, and two levels of organic matter application. The parameters measured were plant height, number of leaves, dry weight, crop N uptake,  Hg content, and uptake of Hg. The results showed that 10% of tailings contaminated soil (T1) contained Hg less than 20% of tailings contaminated soil (T2). The addition of organic material could assist in providing the nutrients needed by plants to improve soil fertility, so the potential for increased uptake and could reduce the content of Hg in tailing contaminated soil. Lindernia crustacea, Digitaria radicosa, and Cyperus rotundus are potential in reducing mercury concentration in tailing contaminated soils that in turn improved maize growth.

Abstract

Gold processing tailings in small-scale gold mine in the form of sludge that still contain Hg and various other metal elements are commonly discharged in agricultural land and water bodies. The discharge of the tailings at Sekotong of West has inhibited growth and yield of maize in the area. The purpose of this study was to explore the potential of Lindernia crustacea for phytoremediation of soil contaminated with small-scale gold mine tailings containing mercury. Lindernia crustacea was grown on the mixture of top soil and (70% weight) and 30% (by weight) of amalgamation or cyanidation tailings for 8 weeks. To enhance uptake of mercury, ammonium thiosulphate was added with doses of 4 and 8 g kg-1 to the planting media when the plant reached 6 weeks old. The results showed that the addition of 4 g and 8 g ammonium thiosulphate increased the accumulation of Hg in the plant shoot by 61% and 27 %, respective, compared to the treatment without addition of ligand. The addition of 4 g and 8 g ammonium thiosulphate also increased 15% and 11% accumulation of Hg, respectively, in the plant root compared to the treatment without addition of ligand. Based on BCF, BAF and TR values, it was known that with or without addition of ammonium thiosulphate, Lindernia crustacean is suitable for use in pytostabilization activities

Abstract

Mercury is one of heavy metals that is highly dangerous as it affects human health when it pollutes soils used for growing plants. The purpose of this study was to examine the potential of Brassica oleracea, Brassica rapa, and Brassica juncea in reducing levels of mercury in mercury-contaminated soil. Each of the three plant species was grown on a 3 kg of soil in a polybag which first contaminated with four concentrations of mercury (0 ppm, 0.5 ppm, 1 ppm, and 1.5 ppm ). The results showed that Brassica rapa accumulated mercury better then Brassica oleracea and Brassica juncea. On the soil contaminated with the lowest mercury concentration (0.5 ppm ), Brassica rapa root was able to absorb 0,081 ppm of mercury, at the concentration of 1 ppm, Brassica rapa root was able to absorb 0,091 ppm of mercury, while at the highest mercury concentration (1.5 ppm), Brassica rapa root was able to absorb 0,311 ppm. The ability of Brassica juncea roots to absorb mercury were better than those of Brassica rapa and Brassica oleracea.

Abstract

Composting of coffee pulp takes a long time in PT.Perusahaan Perkebunan Kalibendo. To speed up the composting time from coffee pulp, a study that was aimed to isolate cellulolytic bacteria with the ability to decompose coffee pulp pulp was conducted at Soil Bology Laboratory, Faculty of Agriculture, Brawijaya University This study consisted of two phases, i.e. isolation and selection of cellulolytic bacteria originated from compost coffee pulp, and application of the selected bacteria onto the coffee pulp. Treatments tested in the secinda phase of this study were K0 (control or without the addition of isolates), K1 (with the addition of isolate SL 1), K2 (with the addition of isolate SL 2), K3 (with the addition of isolate SL 3) and K4 (with the addition of bacterial consortium). The treatments were arranged in a completely randomized design with three replicates. Parameters observed were decomposition rate, cellulose content, pH, C organic content, total N content, and physicals condition of the produced coffe pulp compost. Results of this study indicated that isolated bacteria obtained ware able to produce cellulase enzymes that could be seen from the presence of clear zone around bacterial colonies grown on Carboxymethyl Cellulose (CMC) agar medium. Three of eight isolated cellulolytic bacteria (SL1, SL2, and SL3) were capable of forming biggest clear zone on CMC medium with an average index of cellulolitic of 1.53. Bacterial isolates originated from coffee pulp compost were capable of decomposing coffee pulp. The bacteria consortium treatment (K4) was capable of decomposing coffee pulp faster than other treatments with the decomposition rate of 2.13 g/day

Abstract

Ultisols are potential for growing soybean However, the soils are considered as acid soils having pH <5,5 hindering availability of several nutrients to support plant growth. The problem can be overcome by application of fertilizers and soil amendment fertilization. This study that was aimed to elucidate the effects of application of PGPR (Plant Growth Promoting Rhizobacteria), lime, and compost on soybean growth on an ultisol of Bogor, used RALF (Factorial Complete Random Design) with 2 factors. The first factor was planting medium with 2 levels (Soil + Compost) and (Soil + Lime) and second factor of PGPR formula with 5 levels (F0 control, F1 soybean bacteria formula, F2 bacterial formula of Root and Tuber Crops Institute, F3 bacterial formula of beans, and F4 formula bacteria of other plant). The results showed that soil + compost treatment had more effect on soil biochemical and plant growth than lime + soil. The treatment of soybean bacteria formula (F1) was most effective in increasing ammonium, nitrate and total population of bacteria. The treatment of bacterial formula of Root and Tuber Crops Institute (F2) had an effect of soil plant growth.
