Abstract

Some plant species growing in the contaminated areas, indicated high toleranceand potentially affective in accumulating pollutants in their roots and above groundportions. These plants can be utilized as hyperaccumulators for cleaning up thecontaminated sites. Study on heavy metal and CN contamination and potentialplant species for accumulator is urgently needed in order to understand the problemsand to obtain suitable technology for the solution. This research aims to examineCN accumulator plants growing in CN contaminated tailing to find a possible solutionof cleaning up by using green technology of phytoremediation. Phytoremediation isdefined as clean up of pollutants primarily mediated by photosynthetic plants. Thisstudy aims to characterized plants that grow under extreme contaminated media ofgold mined tailing and to analyse their potencies as hyperaccumulators. Mikaniacordata (Burm.f) B.L.Robinson,Centrosema pubescens Bth and Leersia hexandraSwartz which proven tolerant and dominant in the contaminated site were examinedin this research. The plants were grown in tailing waste media added by 0 ppm CN,2.5 ppm CN, 5 ppm CN dan 7.5 ppm CN using complete randomized design with 5replicates. The results showed that the plants were capable of growing under thehighest level of CN. Among three species, Mikania cordata showed the highestbiomass production followed by Centrosema pubescens and Leersia hexandra. TotalCN accumulation varied between species, the highest was reached in 2.5 ppm CNtreatment i.e. 22.48 mg/kg in Leersia hexandra, followed by Centrosema pubescens(18.92 mg/kg) and Mikania cordata (12.03 mg/kg). The highest CN content was0.085 mg in Mikania cordata treated with 7.5 ppm CN. High ratio of shoot to root CN(>1) was expected in hyperaccumulator plants to indicate that CN was more distributedin the above ground portions than in the roots. In this study the highest shoo to rootCN ratio was showed in Mikania cordata i.e.11.75

Abstract

Leaf NPK fertilizer experiments on pitcher plant (Nepenthes neglecta and ventrata) conducted in May 2008 to March 2009 in a greenhouse, Botany Division, Research Center for Biology-LIPI, Cibinong Science Center, Cibinong. The objective is to study the effect of leaves NPK fertilizer on the growth of the two Nepenthes species tested. Experiments using Random Complete Factorial Design with two factors, namely the two Nepenthes species and threedoses of fertilizer each treatment repeated six times. Growth parameters measured include; long shoot leaves, plant height, number of leaves, number of mature pitchers and growth pitchers. Results showed that the dose of NPK fertilizer provided (2 and 4 ml / lt) have no effect on plant height and number of leaves, but little effect on the number of mature pitchers thanthe control plants. The statistical tests also showed no interaction between the two Nepenthes species with a given dose of fertilizer on the growth of plants. Minimum-maximum temperature recorded in the greenhouse during the experiment was 22.20C and 38.50C. Meanwhile, air humidity between 43,6-64,7%.Key words: Leaf NPK fertilizer, plant growth, pitcher plant

Abstract

The research were carried out to study the potency of Salvinia molesta D.S. Mitchell (Kiambang), Limnocharis flava (L.) Buchenau (Genjer) and Monochoria vaginalis (Burm.f.) Presl (Eceng) for Hg phytoextraction on paddy field contaminated with Hg from illegal mining. The plants were grown on contaminated media from paddy field in Pongkor (68.269 ppm Hg) added by NPK fertilizer (0, 3 and 6 g/pot) and ammonium thiosulphate chelating agent (0, 20 ppm). The result showed that the growth of kiambang,eceng, genjer and padi are significantly different. Chelating agent did not significantly affect the plant growth, meanwhile fertilizer significantly affected the plant growth. Thetreatments resulted in different Hg concentration in the plants. Fertilizer increased plant biomass and so plant Hg content since Hg contents is a function of total biomass and Hg concentration. It can be concluded that based on the criteria of accumulator plant,kiambang is the most potentially Hg accumulator followed by genjer and eceng.Key words: Phytoextraction, Hg, Salvinia molesta, Limnocharis flava, Monochoriavaginalis

Abstract

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.
