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.

The Impact

<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>
