Abstract

Waste of heavy metal lead (Pb) in waters needs to be addressed through phytoremediation because it is toxic to the environment. The purpose of this study is to determine the effect of water hyacinth (Eichhornia crassipes) ability in water to absorb heavy metal Pb and its effects to total dissolved solids (TDS) of groundwater during the phytoremediation process. Using E. crassipes, groundwater samples and Pb(NO3)2 as a source of Pb, the initial characterization of the two samples was previously carried out. Created four treatments of ground water, i.e.:  P1 contains 2 ppm Pb with E. crassipes, P2 contains 4 ppm Pb with E. crassipes, P3 contains 2 ppm Pb without E. crassipes, and P4 contains 4 ppm Pb without E. crassipes. Observation of Pb by method of atomic absorption spectrometry (AAS) and determination of TDS by gravimetric method, each carried out on days 0, 4, 8, and 12. The results show the treatment of 2 ppm Pb, E. crassipes is more effective at absorbing Pb which is 96.0% compared to treatment 4 ppm Pb which is 90.0%. While 2 ppm Pb and 4 ppm Pb as control only 18.5% and 17.5%. Treatment of 2 ppm Pb which uses E. crassipes shows better water quality than concentration TDS 62.55 ppm compared to treatment of 4 ppm Pb with TDS 70.50 ppm while 2 ppm Pb and 4 ppm Pb as a control does not significantly affect to water quality.

Abstract

Heavy metal pollution in the industrial area causes problems in the surrounding vegetation. The study aims to determine the absorption of heavy metals lead (Pb) which accumulates on green champa leaves (Polyalthia longifolia) in the industrial area of Makassar city, and its effect on the number of leaf stomata. Leaf samples were taken at three stations, the method used was random sampling. Measurement of the concentration of heavy metals lead (Pb) by the atomic absorption spectrophotometery method (AAS), observation of the number of stomata using a microscope. The results showed the concentration of Pb that accumulated in green champa leaves, such as 1.21–2.42 µg/g. Heavy metals affect stomata on green champa leaves but do not show significant damage (> 0.05). This shows that the green champa plant has benefits in reducing heavy metal pollution in the air, without experiencing damage to the leaf stomata.

Abstract

Limbah air asam tambang merupakan sumber pencemar pada lingkungan yang bisa mengganggu kehidupan berbagai organisme, dapat ditanggulangi  secara biologis dengan memanfaatkan mikroba dari sedimen lahan basah. Penelitian ini bertujuan untuk mengetahui dinamika populasi mikroba pada air asam tambang dengan perlakuan sedimen  mangrove, perhitungan total mikroba dengan metode  standard plate count .Hasil pengamatan menunjukkan  perlakuan sedimen mangrove meningkatkan pertumbuhan populasi mikroba pada hari ke-15 yaitu 3,5 x 106  sel/ml pada perlakuan I dan 1,53 x106  sel/ml pada hari ke-15 pada perlakuan II, sedangkan pada perlakuan III sebagai kontrol jumlah mikroba hanya 0,2 x 106  di awal inkubasi dan terus menurun hingga hari ke 25.Hasil isolasi mikroba dari sedimen mangrove, didapatkan 13 isolat yang berbeda berdasarkan ciri morfologi secara makroskopis meliputi warna, bentuk, tipe dan elevasi koloni.
