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

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

Phosphate is the second essential chemical element for plants. However, it mostly presents in insoluble form. Using biofertilizers containing phosphate-solubilizing bacteria can increase phosphate solubilization. However, it is often ineffective due to the high temperature of the storage warehouse so the viability and enzyme activity of the microbes can decrease. The aims of this study were to determine the optimum and maximum temperature of phosphate-solubilizing bacteria’s viability, knowing the effect of storage temperature on the bacteria population and halozone of phosphate-solubilizing bacteria, knowing phosphatase activity of phosphate-solubilizing bacteria which were incubated at high temperatures, and knowing the organic acid production of phosphate-solubilizing bacteria which incubated at high temperature. The results showed that 37˚C was the optimum temperature of JBNO6, KT6D, KT7D and EPS5 strains and they could hold the high temperature of 58˚C (thermophilic). The ability of all strains in dissolving the P-insoluble decreased at high temperatures. However, the enzyme activity would go back again at room temperature (reversible). The acid phosphatase value of all phosphate-solubilizing bacteria strains was higher than the alkaline phosphatase value in the entire storage temperature. At high temperatures, KT6D was capable of producing oxalic acid and KT7D was able to produce acetic acid. EPS5 was the highest in the ability of phosphate solubilizing, the ability to produce the phosphatase enzyme and the bacteria population compared with JBNO6, KT6D and KT7D.

Abstract

Forest conversion for plantation and the continuous fertilizer usage without organic materials has potentials to produce soil damage with the soil compaction. One of efforts to improve sustainable land productivity is by applying organic materials. The use of organic materials of vermicompost, fruit peel fertilizer, and cow manure in long term is expected to be able to improve the physical properties of soil at the robusta coffee plantation (Coffea canephora  Pierre). The research was conducted at robusta coffee plantation of PT Perkebunan Nusantara XII (Persero), Bangelan Village, Wonosari District, Malang Regency. The research used factorial random design of nested pattern with 2 factors: (1) organic material treatment (control, vermicompost, coffee fruit peel fertilizer, and cow manure),  (2) the soil depth level (0-10 cm, 10-20 cm, and 20-30 cm. The results showed that application of vermicompos improved higher organic matter than the application of coffee peel fertilizer, cow manure in depth of 0-10 cm. The application of various organic materials did not improve the organic materials of soil in depth of 10-20 and 20-30 cm. The application of vermicompost, coffee peel fertilizer and cow manure improved aggregate stability than without the application of organic material (NPK). Organic materials had a positive relation with soil aggregate stability in depth of 0-10 cm (r = 61%), so the higher organic material content, the higher soil aggregate stability, while in depth of 10-20 cm and 20-30 cm there was no significant relationship
