Chromium metal is one of the heavy metal wastes from various industries and is persistent for the agricultural environment, especially in rice fields. Chromium metal can change biodiversity and ecosystem function in paddy soil. Chromium metal phytoremediation that pollutes paddy soils with hemp (Boehmeria nivea) is important because paddy soils play a role as a living medium for food crops, especially rice (Oryza sativa). One indicator of the success of phytoremediation is the reduction of chromium metal content in the soil, so it requires a policy system to maintain a healthy environmentally friendly agriculture. This study aimed to determine the ability of Boehmeria nivea to reduce levels of chromium metal in the soil and provide policy solutions to keep environmentally healthy agriculture. This study used a complete randomized block design, random sampling of chromium metal data. The results showed the initial concentration of chromium metal in the soil was 2.36 ppm, after treatment with the interaction between Agrobacterium sp. I3 with Boehmeria nivea (P0B1T1) and interaction of organic matter (compost) with Boehmeria nivea (P0B2T1) obtained Cr 1.37 ppm metal content with a decrease of 42.01%. The resulting policy solution is the Environment Health Agriculture System (EHAS). The conclusion of this study was phytoremediation of chromium metal using Boehmeria nivea combined with the Environment Health Agriculture System can create a healthy environmentally friendly agricultural system.

ABSTRACTChromium is hazardous pollutant for ecosystem caused chromium especially inhexavalent form is very toxic, has high solubility and mobility, teratogenicity, mutagenicity andcarcinogenicity to living system related with its oxiding power. Remediation of soilcontaminated of heavy metals was important caused soil as medium for food producing.Conventional methods for heavy metals remediation consist of physical and chemical processbut these applications were costly and less effective. One of the remediation technologies is theusing living organisms such as microorganisms, because they have ability to reduce Cr(VI) intonon toxic form, Cr(III). The aims of this research were to evaluate the reduction activity ofrhizobacterial isolate and to identify the isolate which take a role in reducing chromiumabsorption by plant. The results showed that Isolate 39 was able to grow on LB mediumcontaining 200 ppm Cr(VI). Isolate 39 reduced Cr(VI) up to 15 ppm concentration level inminimal medium. Isolate 39 has ability to reduce Cr(VI) both at growing cells and resting cellsconditions up to 100% and 51% within 18 hours, respectively. Isolate 39 increased thephytostabilization ability of chromium by Zea mays at 30 days after seeding 3.8 timescompared than control. Based on physiological characteristics and partial sequencing of 16SrRNA gene, Isolate 39 was identified as Agrobacterium sp.Key words : Agrobacterium sp, hexavalent chromium, reduction, Zea mays

Industry sector exerts a negative effect on the environment. Industrial waste is often disposed to the rivers. The industry contributes to the accumulation of heavy metals in the environment. In farming sector, the accumulation of heavy metals can result in water pollution and be washed into the ground. Therefore, the farming product can be contaminated with heavy metals and they can be harmful to human health. The objective of this research was to reduce the Pb heavy metal content in paddy soil. This research was taken place in the Pb contaminated paddy soil using a randomized complete block design with three factors and three replicates. This research employed combination of inorganic fertilizer, ramie and Agrobacterium sp. I3 or compost as a chelator to improve Pb uptake. The results showed that combination of the three treatments increased Pb uptake. The combination of chemical fertilizers, ramie with compost increased the Pb uptake of 11.93 μg/g or 45.9%. The combination of chemical fertilizers, ramie with Agrobacterium sp. I3 resulted in the highest Pb uptake of 12.85 μg/g or 49.8%. The combination also decreased the soil Pb level by 7.8 μg/g or 23.5% of the control.

Irrigation with textile wastewater and fertilization with an inorganic fertilizer containing lead (Pb) have negative impacts for agricultural sectors, especially lead contamination in a rice field and its uptake by rice plant. The rice grain that contains Pb is dangerous if consumed by humans, so it needs treatment to suppress Pb uptake by rice. Agrobacterium sp. I30 and vermicompost have a role as chelating heavy metals agents. The purpose of this study was to determine the effect of the chelating agents to suppress Pb uptake by rice in Kebakkramat, Karanganyar of Central Java. The method used was the quantitative method through a completely randomized block design with two factors (inorganic fertilizer and chelating agents). The results showed that application of Agrobacterium sp. I30 without inorganic fertilizer decreased Pb content in rice from 5.03 mg/kg to 4.97 mg/kg with a decrease in Pb uptake of 6.28%. Application of vermicompost without inorganic fertilizers decreased Pb content in the rice from 5.03 mg/kg to 1.61 mg/kg, with a decrease in Pb uptake of 72.18%. The use of both chelating agents can be recommended to suppress Pb uptake by rice in polluted soil and increases the safety of rice for consumption.

In the small gold mining regions of Indonesia, the tailings or waste water containing mercury commonly may be released into agricultural lands resultimg soil contamination. Phytoremediation is a low-cost and environmental friendly alternative to traditional techniques such as soil heating, soil removal, and soil washing. In this study, a sweet sorghum combined with the inoculation of a rhizobacteria, Agrobacterium tumefaciens, was tested in a field experiment with mercury contaminated soil from a small scale gold mining. Plant growth, uptake and accumulation of mercury by the sweet sorghum, and effects of the Agrobacterium tumefaciens inoculation on mercury accumulation were investigated. The average of mercury content in the soil was 3.76 mg/kg. The results showed that the sorghum grew well, and the inoculation of Agrobacterium tumefaciens promoted the plant growth, but did not increased the mercury concentration in both root and stem parts of the sorghum. The accumulation of mercury was 6.2?/plant for sorghum without Agrobacterium tumefaciens, and 14.0?/plant for sorghum with Agrobacterium tumefaciens. It was estimated that the phytoremediation efficiency of mercury was 414 and 934 mg/ha for sweet sorghum without Agrobacterium tumefaciens inoculation and with Agrobacterium tumefaciens inoculation, respectively.

Logam berat bersifat persisten dalam lingkungan dan diketahui mengubah biodiversitas, struktur dan fungsi ekosistem tanah. Remediasi tanah terkontaminasi logam menjadi penting, karena tanah sebagai media penghasil bahan pangan. Pendekatan konvensional untuk remediasi tempat yang terkontaminasi logam meliputi fisika dan kimia, namun aplikasi proses-proses ini terbatas karena kendala teknologi dan ekonomi. Oleh karena itu diperlukan metode remediasi yang murah, aman dan ramah lingkungan seperti bioremediasi. Penelitian ini bertujuan untuk mengetahui kemampuan rhizobakteri dalam membantu fitoekstraksi logam berat kromium pada tanaman jagung. Tahapan penelitian meliputi 1) uji toleransi bakteri terhadap Cr(VI), 2) uji reduksi Cr(VI), dan 3) uji serapan Cr(VI) pada tanaman jagung. Hasil penelitian menunjukkan bahwa Isolat 27 toleran terhadap toksisitas Cr(VI) pada konsentrasi 15 ppm. Isolat 27 mereduksi Cr(VI) secara sempurna dalam waktu 18 jam. Isolat 27 membantu fitoekstraksi logam kromium pada tanaman jagung sebesar 241 kali dibandingkan kontrol. Perlu penelitian lebih lanjut untuk mengetahui jenis asam yang berperan dalam mekanisme fitoekstraksi pada tanaman jagung. Isolat 27 dapat digunakan sebagai inokulan dalam fitoremediasi dan pemacu pertumbuhan tanaman.
