    Tolerant plants that can still be living in the mining area, because of the possibility of symbiosis with microorganisms, including mycorrhizal types, the spores of living microorganisms in the mot zone through the fonmation of roots and symbiotic hyphae penetrate the root epidenmis cells. Interwoven hyphae that will serve to expand the field of far-reaching absorption of nutrients from the soil surface, especially the elements and phosphate can also act as a filter absorption of heavy metals by plants. Research on the exploration diversity of indigen MAF spores conducted in five locations (at Wika 1, Kelok S, Kampung Jawa, KIM 2, and East Pit) mining area coal PT. KIM in Muara Bungo, Jambi, This research consists of two phases, the first phase of soil sam piing in the field and the second stage is the isolation and identification of AMF infection as well as observations in the laboratory, analyzed the data descriptionThe results showed that in the area; The MAF spores found were : 13 of Glomus , Septoglomus constrictum, Rhizophagus Clarus, and Septoglomus deserticofa species. While the infected MAF on plant are: Chromolaena odorata (60%), Matlotus pannicutatus (60%), Cyperus sp. (40%), Hevea brassiliensis (60%), Axonopus Paspalum (90%), A.compressus (80%), Ipomea triloba (70%) and Cfidemia hirta (100%).

    Potential Research Bioremediation of POPs (Persistent Organic Pollutant) in Indonesia
    (2015-01-27) Rossiana, Nia; Dhahiyat, Yayat
    The Stockholm Convention aims to protect human health and environment from Persistent organic pollutants (POPs). As a country has ratified the Stockholm Convention, Indonesia has obligation to conduct activities with the final goal of reducing and the phase out of POPs. POPs are !2.!lm!lilo comoounds that are resistant to environmental degradation through chemical. biolooical. and ohotolvtic processes. Because of this, they have been observed to persist in the environment, to be capable of long-range transport, bioaccumulate in human and animal tissue, bioaccumulate in food chains, and to have potential significant impacts on human health and the environment. Persistent Organic Pollutants (POPs) become one of the major problems for the environment in the last years. Their properties that can resist in the atmosphere for several years and easy moving over the long area, make this problem become mora serious. Identification of Contaminated site and remediation in an environmentally sound manner, but recently remediation has not been perfomed. In Indonesia, Research bioramediation of organic pollutants have been carried out by researchers at universities and research institutes both LIPI, Pusarpedal, BPPT and other research institutions. Bioramediation Indonesian Forum has been established and its action immediately realized in field applications

    Using Daphnia carinata KING on Toxicity Test Pre and Post Phytoremediation of Oily Sludge
    (2016-03-31) Rossiana, Nia
    The performance of a bioremediation of oily sludge process can be determined by measuring the reduction of contaminant concentrations and by assessing the treatment's ability to lower toxicity. Land treatment of polycyclic aromatic hydrocarbon (PAH)-contaminated soil from oily sludge. Acute toxicity, as measured by the Daphnia survival assay, testing bioremediation medium is very necessary for the health of the soil and water from the pollutants. Bioremediation of oily sludge using bacteria (pre) and post phytoremediation decline in levels of TPH. Although toxic levels decreased, urgent toxicity tests on organisms to determine of bioremediation are safe for the environment. The aim of this research is to observe acute toxicity level LC50-48 hours medium of oily sludge composted by bacteria, post phytoremediation and influence to reproduction of Daphnia carinata King. To get LC50-48 hours value, used static bioassay according to standard of APHA (1995) counted with Minitab Probit Analysis. For chronic toxicity test medium of oily sludge prae and post phytoremediation to reproduction of D. carinata King, counted the total of neonates D. carinata King during 21 days. The result showed that LC50-48 hour’s value of medium of oily sludge prae phytoremediation is amount 1043,69 ppm and post phytoremediation is amount 4728, 7 ppm. For chronic toxicity test, total of neonates Daphnia carinata King in medium of oily sludge pre phytoremediation is amount 34 neonates with frequency of brood 4-6 times and the size 0,75 mm. While post phytoremediation is amount 37 neonates of brood are 5-7 times and the size 0,77 mm
