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

Drought Tolerance Assay on Resulted Mutation of Arrowroot Plant (Maranta arundinacea L.) with Gamma Irradiation. Selection of garut (Maranta arundinacea L.) toward drought stress was conducted in induced mutant by using provenance plants from some semi aridregions of East Jawa. In this research three provenance were used 1) Garut from Dusun Pogal, Desa Lebakrejo, Kec. Purwodadi, Kab. Pasuruan (N1); 2) Garut from Dusun Sembung, Desa Parerejo, Kec. Purwodadi, Kab. Pasuruan (N5); 3) Garut from Dusun Genitri, Desa Gunting, Kec. Sukorejo, Kab. Pasuruan (N8). Provenance plants were treated with mutation induction using several levels of gamma radiation i.e. 0, 10, 20 and 40 Gy. The inducted plants were thenplanted in optimum environmental condition for acclimatization. After 5 months the plants were placed in a greenhouse for water stress treatments. Three levels of water regimes 1) optimum water (field capacity Ø = -0,3 to -1,5 Mpa); 2) 7 days watering interval (Ø =-1,0 to -11,0 Mpa); 3) 14 days interval (Ø = -4,0 to -15,0 Mpa). Plant drought tolerance was examined by analyzing morphological and physiological characteristics related to drought tolerant characteristics, including stomatal conductance (stomatal opening), transpiration, rate of CO2 assimilation, biomass production and yield, Harvest Index and drought Tolerance Index. The resultsshowed that radiation treated plants were more capable of maintaining their water potential (Ø). This indicated by significantly higher values of Ø in treated plants i.e. -2.95 Mpa(10 Gy),-2.86 Mpa (20 Gy) and -2.84 Mpa (40 Gy), compared to -3.74 (Untreated plants). Drought stressed plants produced total biomass 79,55 g/plant, much lower compared to unstressed plants (308,20 g/plant). The highest yield was N8 (219,53 g biomass and 139,83 g tuber), followed by N1 (183,32 g biomass and 126,20 g tuber) and N5 (178,8 g biomass and 136,64 g tuber). Drought Tolerance Index of untreated N1 was the highest (1,27), followed by N5 treatedwith 40 Gy (1.22), N1 with 10 Gy (1.17) and N8 with 40 Gy (1.00). Among radiation treatments, untreated plant produced the highest yield followed by the plants treated with 10 Gy, and the lowest was treated with 40 Gy.Keywords: Drought, tolerance, Maranta arundinacea, mutation, gamma, radiation

Abstract

ABSTRACTPotency of Hypertolerance and Metal Absorption of Some Plant Species Under GoldMine Waste. Degraded mined land is characterized by extreme of alkalinity or acidity, highconcentration of soluble salt and high concentration of heavy metals. Contamination of minedsoil and water affects not only on agriculture system but also on food chains andepidemiological problems. As soil metal can not be biodegraded, remediation of soil heavymetal risk has been a difficult and expensive goal. Remediation of hazardous soil is requiredto reverse the risk to humans and the environment. Recently there are several differentstrategies available for the clean up and restoration of contaminat6d soils i.e conventionalwhich is mainly engineering-base and phytoremediation which is a biological-base method.Phytoremediation is defined as: clean up of pollutants mainly mediated by photosyntheticplants.. In this research four species of plants i.e Mimosa pigra, Crotalaria juncea, Crotalariasp. and lpomoea sp. were studied their potencies as hypertolerant plants on the waste of PTANEKA TAMBANG and public mines of Pongkor and Cigaru. The results showed that theplants were able to grow and showing high tolerance to the contaminated media. The mosttolerant species was lpomoea followed by Crotalaria and Mimosa. The results raised someprospectsfor phytoremediation technology for rehabilitating contaminated mined lands.Keywords: Phytoremediation, hypertolerance

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

Learning media used in anatomy courses in human physiology have not utilized information technology integration. Learning activities carried out are still in the form of discussion presentations by utilizing power point media that tend to less activate the thinking ability of students so that the concept of material delivered is difficult to understand. The purpose of this study was to collect information in the form of fundamental problems in the study of human physiology anatomy so that it can be used as a basis for the preparation of multimedia with the STEM Education model. The method used in this study, namely Research and Development refers to the Thiagarajan development model, namely stage 1 (define) and stage 2 (design). The instruments in this study were (1) interview transcripts, (2) observation transcripts, (3) questionnaires, and (4) documentation. The results of the needs analysis show that as follows (1) 31.75% anatomical learning of human physiology is less interesting in terms of models and learning media. (2) 7.14% of students have known the STEM Education model. (3) 88.10% of students need learning media integrated with information technology and learning models that familiarize them with critical thinking skills. (4) human physiology anatomy subjects suggest using multimedia with the STEM Education model that matches the characteristics of students and the curriculum used. Based on the results of the above research it can be concluded that it is very necessary to develop multimedia anatomy of human physiology with the STEM Education model. Suggestions for further research are to carry out a multimedia design that is integrated with technology based on student characteristics and stimulates students' critical thinking skills.
