Ultisol is the main type of land in Kalimantan, Sumatra, Papua and Sulawesi, with an area of almost 45.8 million ha or 25% of the land area of Indonesia. Ultisol has a relatively high acidity (average pH 4.5), high Al saturation, reaching 60%. The efforts to increase the fertility of ultisol soils such as the addition of organic materials such as Empty Oil Palm Bunches (OPEFB) and CFA (Coal Fly Ash) or Coal Fly Ash (CFA) improve the physical properties of Ultisol soil. Use of CFA that exceeds the limit can cause pollution especially copper (Cu) and lead (Pb). One way to recover soil from heavy metal contaminants with Phytoremediation technology, mustard (Brassica juncea L.) is one of the plants that easily absorb heavy metals so that it can be used as a Phytoremediation agent. The aims of this research to determine the use of CFA and OPEFB to fix up the ultisol soil and heavy metal content absorbed by plants. This study used Completely Randomized Design with 3 replications. The results showed that using of CFA and OPEFB can increase the available P so that it can increase the growth of mustard plants and absorption of heavy metals. By using the dozes of 54.54g CFA and 18.18g OPEFB (C3K1) can increase P- available at 181.67 m kg-1 . The uptake of heavy metals Cu and Pb in mustard plants is very high. The highest uptake in Cu reached 192.03 mg kg-1 , whereas in Pb it was 80 mg kg-1 . This number is still very high, so it is dangerous if consumed.

ABSTRACT: Phytoremediation is a useful tool to restore heavy metals contaminated soils. This study was carried out to test two castor (Ricinus communis) cultivars [Local and DS-30] for phytoextraction of heavy metals from the soil spiked by known concentrations of seven metals (Cu, Cr, Fe, Mn, Ni, Pb and Zn). A pot experiment was laid out by using a completely randomized design. Soil and plant samples were analyzed at 100 days after planting. The data on heavy metal uptake by plant tissues (roots, leaves and shoots) of the two castor cultivars suggested that a considerable amount of metals (Fe = 27.18 mg L-1; Cu = 5.06 mg L-1; Cr = 2.95 mg L-1; Mn = 0.22 mg L-1; Ni = 4.66 mg L-1; Pb = 3.33 mg L-1; Zn = 15.04 mg L-1) was accumulated in the plant biomass. The soil heavy metal content at the end of experiment significantly decreased with both cultivars, resulting in improved soil quality. Therefore, it is concluded that both castor cultivars, Local and DS-30, can be used for phytoremediation of heavy metal-contaminated sites.

<p class="Els-Abstract-text">Plants growing in soil containing heavy metal  polutan such as chromium (Cr), lead (Pb), cadmium (Cd) and copper (Cu)  will be stunted, and  increase production of Reactive Oxygen Species (ROS). In dealing with the excess amount of ROS, plants have an enzymatic defense system, using superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxide (APX). The aim of this study was to determine and analyze the <em>Sonchus oleraceus</em> (Linnaeus, 1753) plant response to heavy metals stress, seen from the growth and antioxidative defense enzymatically. Research carried out using a Completely Randomized Design (CRD) with four treatments and five replicates. The metal treatment was 10 mg · L<sup>–1</sup>. The presence of heavy metals in the growing medium significantly decreased the plant height and leaf area, so the impact is on the weight of wet and dry weight. The metal treatments of Cr, Cd, Pb and Cu increase the activity of SOD and APX enzymes but decrease the activity of the CAT enzyme. Chromium is a metal that has a significant influence on the growth and activity of SOD, APX, and CAT enzymes in <em>S. oleraceus</em>.</p><div><p class="Els-keywords"><strong>Keywords:</strong> antioxidative responses; growth; heavy metal; <em>Sonchus oleraceus; </em>toxicity.</p></div>

In recent decades several industrial activities polluted the soil, which caused the accumulation of heavy metals to an extent greater than the natural concentration. This is mainly typical of countries, where mining and industry plays or has played an important role in the economy. The utilization of these lands is an economic interest, since locating the contamination, controlling its spreading and maintaining the area has costs. One of the methods for remediation is phytoextraction, during which heavy metals, especially harmful to water and soil, are removed from the soil by plants capable of accumulating contaminants. However, during the combustion of these plants their heavy metal content is replaced into the formed gaseous and solid combustion remains, so the hazard, composition and treating method of these remains must be defined by the appropriate examinations. In this article we present some part of the results of this research, where we examine the gaseous and solid pollutant content of flue gas formed during combustion, as well as the heavy metal content of fly ash. We made two different experiments for domestic and semiplant usage. We have used oak and poplar from a heavy metal contaminated area in both experiments. The domestic examination was conducted in a 7 kW hearth with a closed combustion chamber, the semiplant examination was carried out in a 0,5 MW capacity furnace equipped with an automatic fuel feeding system and a cyclone dust extractor. We have measured the composition of flue gas in both firing experiments with a HORIBA PG-250 type portable gas analyzer, in the case of the analysis of heavy metal content of fly ash DX4 EDAX EDS microprobe of an AMRAY 1830 I scanning electron microscope and ICP-AES, using a 720 ES instrument was used. Based on our results, it can be determined, that the combustion device used to burn biomass grown on heavy metal polluted areas – brownfield lands – must make it possible to separate fly ash from the flue gas and allow the handling of solid burning residues.

Abstract Microalgae species Nannochloropsis sp. can used as heavy metal biosorben because of it’s adsorption capability that caused by the active cluster which contained in that species (Sembiring et al., 2008). Chlorella sp. is one of phytoplankton species that has the bioaccumulation ability of heavy metals and easily cultivated (Arifin, 1997). Lead (Pb) is a mineral belonging to microelements, is a heavy metal and is a potentially toxic material. Water bodies that have been polluted by compounds or ions Pb because can lead to the death of aquatic biota, the number of Lead (Pb) present in water bodies exceeding the proper concentration (Palar, 2004). One way to anticipate the increasing heavy metal pollution in the water is to bioremediation. The research using experimentally, the research design used was completely randomized design (CRD) consisting of four treatments with five replications. The concentrations of heavy metals Plumbum (Pb) used is 0 ppm and 0.9 ppm. The main parameters in this study is the ability of bioremediation Plumbum (Pb) by Nannochloropsis sp. and Chlorella sp. SPSS analytics normality test results and test the ability of T 95% in Nannochloropsis sp. and Chlorella sp. in absorbing heavy metals Plumbum (Pb) concentrations of 0 ppm and 0.9 ppm indicate that the data is normal and the results obtained were significantly different / significant. While the analysis of SPSS test T on heavy metal absorption capability comparison Plumbum (Pb) concentration of 0 ppm and 0.9 ppm by Nannochloropsis sp. and Chlorella sp. showed that the results were not significantly different / non significant. On average results obtained, Nannochloropsis sp. have a higher capacity than Chlorella sp. in the bioremediation process of heavy metals Plumbum (Pb).
