Influence of soybean meal concentration and 20 kinds of L-amino acids in iturin A production. Theuse of chemical pesticides has caused serious environmental problems and thus the demandfor safer pesticides is increasing. One alternative is microbial pesticides that suppress fungaland bacterial of plant pathogens. Bacillus subtilis has been known as producer of lipopeptideantibiotics, like iturin A, plipastatin and surfactin. In this study, iturin A as an antifungal of planpathogens was produced on varieties of soybean meal concentration; i.e. 8%, 10%, 12%, and15% using B.subtilis RB14-CS.The result indicates that 8% soybean meal concentration produced the highest of iturin Aproduction ( 2469 mg L-1) compared to the others. Beside the effect of nitrogen source (soybean), the influence of 20 kinds of L-amino acids on an enhancement of iturin A productivitywere observed. The examined L-amino acids were L-ala, L-arg, L-asn, L-asp, L-cys, L-glu, L-gln,L-gly, L-his, L-ile, L-leu, L-lys, L-met, L-pro, L-phe, L-ser, L-thr, L-tyr, L-trp and L-val. The resultsshow that no one of them could improve the iturin A productivity on soybean meal medium.

Principally, solid waste management is all activities of solid waste handling, from thepoint sources until the final disposal. Up to know solid waste management in urban areais still a complex problem, either from social, management, and technology aspects.The other problem of solid waste management is due to the people behaviour, whichis mostly still unaware. Social capacity is another word social capital means a socialcondition that a lot of citizens participate the process of decision making or policymaking and cooperation with government. The role of community in this system is onlyin paying the monthly fee. So that people still fully gave the solid waste managementsystem in to the government. There is no indication of solid waste sparation by thepeople them selves.

The increasing number of resident in an area impact to the increasing number ofdomestic waste produced by that area.The amount of existing landfill waste is notenough to accommodate all waste.This is the reason why the researchers need todevelop a landfill waste with good performance. Good performance landfill can treatwaste quickly and does not contaminate the environment. Methan gas produced by thelandfill waste can be used as alternatif energy resources. To improve the performance oflandfill waste, the waste management in landfill waste need to be monitored. The landfillwaste monitoring carried out on quality of leacate, volume and concentration of gas,and some other parameters. To facilitate the monitoring process should be developeddatabase software for landfill waste performance monitoring. With this software the datais managed in such a way so that it can be called back quickly and easily and can bedisplayed in various forms of landfill performance analysis reports

Mercury is one of important contaminants in mine lands. One approach to remediaterisks from this metal pollutant is phytoextraction using hyperaccumulator plants. Theseremarkable plant species accumulate appreciable high concentrations of metals thando normal plants when the normal plants suffer yield reduction from metal phytotoxicity.Some plant species growing in gold mine contaminated areas indicated high toleranceand potentially effective in accumulating mercury in their roots and above groundportions. Salvinia molesta is one of them. This plant could be utilized as hyperaccumulatorfor cleaning up mercury contaminated sites. This research aim to study phytoextractionof mercury by Salvinia molesta and the effectiveness of mercury degradator bacteria onplant tolerance and mercury phytoextraction. In this study Salvinia molesta was grown inmercury contaminated liquid gold mine waste, added with Mercury (II) Chloride (HgCl2)0 ppm Hg, 10 ppm Hg, 30 ppm Hg and 50 ppm Hg. Mercury degradator bacteria wasapplied in the media. The results showed that Salvinia molesta was able to survive evenin media with high level of mercury concentration (50 ppm), although the number ofplant survival tend to decrease with the increase of mercury concentration. Variables ofsurface coverage and live plants decreased with the increase of mercury concentrationin the media. There was a close correlation between plant growth variables and mercuryconcentration in the media. The effects of mercury toxicity on plants seems to decreasein bacteria treated plants. It was indicated by the higher percentage of surface coverageand plant survival in bacteria treated plants than that of untreated plants up to 30 ppm Hg.Recovery from toxicity was shown in bacteria treated plants up to 30 ppm Hg. Mercuryaccumulation in plants tent to increase with the increase of mercury concentration inmedia. It can be concluded that plant performance was better and mercury concentrationdecreased in bacteria treated plants.
