Jurnal Lahan Suboptimal: Journal of Suboptimal Lands (JLSO) (p-ISSN 2252-6188; e-ISSN 2302-3015) publishes original research papers, literature reviews, and short communications that cover on topics relevant to suboptimal lands: freshwater swamps, tidal lowlands, peatlands, dry and dry acid lands, shaded ecosystem, ex-mined lands, saline and marine coastal wetland ecosystems. The Journal serves as a multi-disciplinary forum covering key issues in Suboptimal Lands science and technology, management, policy and ecological economics. The journal is published by Pusat Unggulan Riset Pengembangan Lahan Suboptimal (PUR-PLSO), Universitas Sriwijaya. The journal was first published on April of 2012 with twice per year in frequency on April and October.

Abstract

This research aimed to determine synergies between bacteria indigen with lamtoroin bioremediation processes at various concentrations of sludge through the measurement ofvariables, and the number of bacteria, impairment of Total Petroleum Hydrocarbons (TPH), andweight of lamtoro gung. Experimental design used was Complete Randomized Design (CRD) with5 treatments and 5 replications, increase the concentration sludge treatment is control (0%), 2.5%,5%, 7.5%, and 10% of sludge. The study found that given sludge concentration increases causingthe higher number of bacterial populations. Sludge concentration decreased significantly affectTPH values and highest TPH values decrease at 7,5% concentration of sludge. Sludgeconcentration significanly affect the wet weight and given treatment sludge, Lamtoro wet wieghtdecreased at the end ofthe study

Abstract

The discharge of mercury amalgamation and cyanidation tailings of small-scale gold mining in West Lombok to agricultural lands caused Hg, Cd, Cu, Pb and Zn contamination. Phytostabilization may be a feasible approach for the management of contaminated sites. The objective of this study was to search for tree species that are potential for phytostabilization of soils contaminated by small-scale gold mine tailings in West Lombok, Indonesia. Results of this study showed that there were at least 28 tree species found in areas contaminated by gold cyanidatation tailing. Based on cyanide concentration, Hg concentration, and energy of above-ground parts of the identified plants, Duabanga moluccana (DM), Erythrina orientalis (DM)., and Paraserianthes falcataria (PF) were selected to study their phytostabilization potential. Results of plant growth experiment showed that the tolerance of the three species to heavy metals was in the order of Zn > Pb > Cu > Cd. The highest concentration of Cd (0.9 mg/kg) was found in the roots of DM. The highest concentration of Cu (37,7 mg/kg) was found in roots of EO. Roots of PF contained the highest concentrations of Pb (37.7 mg/kg) and Zn (546 mg/kg). The three plant species had metal shoot / metal root ratios of less than one. This indicates that Duabanga moluccana, Paraserianthes falcataria, and Erythrina orientalis are suitable for phytostabilization of Cu, Pb, Cd, and Zn in gold cyanidation tailing contaminated soils of West Lombok, Indonesia
