Abstract

ABSTRACTPotency of Hypertolerance of Calopogonium mucunoides, Centrosema pubescensand Cajanus cajan . Grown on Gold Mine waste Media Contaminated by Cyanideand Mercury. Cleaning up contaminated environment by using green technology ofphytoremediation is urgently needed in the future. These plants will be utilized ashyperaccumulators for cleaning up the contaminated sites. The results of plant screeningshowed that some plant species, which grow in the contaminated areas, indicated hightolerance and potentially effective in accumulating cyanide and mercury in their rootsand above ground portions. Those plants are Calopogonium mucunoides and Centrosemapubescens. This research aims to examine the potency of three candidate plants i.eCalopogonium mucunoides, Centrosemapubescens and Cajanus cajan, that were grownunder three different media i.e tailing waste of PT ANTAM contaminated by cyanide,public mine or PET1 waste that were contaminated by mercury and non contaminated topsoil as a control. The results showed that all of the species were able to grow undercontaminated media and showed a considerable tolerance by indicated high cyanide andmercury accumulation in their shoot and root. Among those three plants, Centrosemapubescens showed the highest level of cyanide and mercury accumulation i.e 3.29 mg I- CN (in the shoot), 34.72 mg I- Hg (in the shoot) and 17.47 mg lk Hg (in the root),followed by Calopogonium mucunoides i.e 14,97 mg I- CN (in the root). Concentrationratio of CN and Hg accumulation in shoot/root of Centrosemapubescens was >I indicatingthat this plant, according to the definition can beconsidered as a hyperaccumulator.Key Words: Calopogonium mucunoides, Centrosemapubescens, Cajanus cajan, mercury,cyanide, waste

Abstract

ABSTRACTEffectivity of EDTA (EthylenediaminetetraceticAcid) in Increasing Lead Accumulationof Saccharum spontaneum Grown Under Gold Mine Waste. Lead (Pb) isknown as one of a major metal contaminant in mine tailing. This metal has low solubility,and in many cases, is not readily available. In most soils capable of supporting plantgrow, the soluble Pb2+ levels are relatively low and will not promote substantial uptake bythe plant. In addition, many plants retain Pb2+ in their roots with only minimal trabsportto the aboveground plant portions. Therefore, it is important to find ways to enhance thebioavailability of Pb2+ or to find specific plants that can better translocate the Pb2+ intoharvestable portions for phytoremediation. The success of Pb phytoremediation is tohave significant Pb availability as well as a large quantity of plant biomass with high rateof growth. This experiment was conducted to obtain both purposes. Saccharumspontaneum which proven tolerant and dominant in contaminated area as well as potentialin producing high biomass was used in this research.The plants were grown in wastemedia added by 100 ppm, 200 ppm and 300 ppm of Pb. Ethylenediaminetetracetine Acid(EDTA) was applied to increase Pb availability and plant uptake as well as translocationto the aboveground portions. The results showed that the plant still capable of growingunder the highest level of Pb. EDTA increase Pb availability and plant uptake. Pb accumulationin the aboveground biomass of EDTA treated plants were relatively higher thanuntreated plants.Key words: Timbal, EDTA, phytoremediation

Abstract

Plants show different physiological responses to light intensities. Study on optimum light intensities for different plants is important, especially for commercial plant commodities, such as industrial plantation plants. This research aims to study the influence of shading and fertilization treatments on plant growth and the activity of some physiological process of four industrial trees namely Cacao (Theobroma cacao), Coffee (Coffea arabica ),  Rubber (Hevea brasiliensis) dan  Clove (Syzygium aromaticum). This research was conducted at Cibinong Science Center LIPI. Two treatment factors applied were three levels of shading : 0%, 55%, 75% and three levels of N ferlitizer: 0 g/plant, 5 g/plant and 10 g/plant arranged in Randomized Block Design with five replicates. Result of experiment revealed that all plant species showed the best growth performance and optimum physiological activities under 55% of shade level in combination with 10 g of N fertilization. The highest CO2 was 13.07 µmolm-2s-1  (55%  shad). The highest values of transpiration and stomatal conductance were 7.56 molm-2s-1 dan 0.73 molm-2s-1 (55% shade). The highest carbohydrate content was 22.49% (under 0% shade) and the lowest was 12.74% (under 75% shade). Keywords: Physiological activity, growth, shading, fertilization

Abstract

ABSTRACTFoxtail millet [Setaria italica (L.) Beauv.] is one of potential cereal plants that can be developed as a source of carbohydrates in marginal and dry lands. The purpose of this study was to examine the tolerance to drought of foxtail millet accession of Buru Merah as a result of gamma radiation treatment. In this study, the seeds of the Buru Merah accession were treated with gamma ray at doses of 0, 25, 50, 100 and 200 Gy. The established growing plants were then treated with different intervals of watering, which were every day (as control), 2 days, 4 days, and 6 days which were arranged in factorial randomized block design with three replications. The observed variables were increase plant height, increase of leaf number, leaf chlorophyll content, plant water potential and  yields. The results revealed that the radiation treatment did not show any significant difference in the production of plant biomass. With radiation treatments of 0, 25, 50 and 100 Gy. and a two-day watering interval the plants can still maintain its water potential above -3 MPa and showing optimum growth. However radiation treatment resulted a significant difference in panicle production, especially between the radiation dose of 200 Gy. and others. The combination of 0-100 Gy. radiation treatment and 2-day watering interval produced plants with optimum panicle production.Keywords: drought, growth, millet, production, radiation, tolerant
