Studi Perbandingan Kadar Logam Berat (Fe , Mn , Zn , Pb , Cu , Al ) dan Na pada Debu Erupsi Gunung Sinabung dan Tanah Sebelum Erupsi

Abstract

Levels of heavy metals contained in the dust from the eruption of Mount Sinabung in Karo land has been analyzed , reference to heavy metals were analyzed include metals Fe , Mn , Zn , Pb , Cu , Al and Na . Each of these heavy metals in dust samples eruption subsequently measured concentration using Inductively Coupled Plasma tool ( ICP ) . Each concentration of heavy metals in dust samples eruption obtained as follows: Fe ( 37.06 ppm ) , Mn ( 0.20 ppm ) , Zn ( 1.76 ppm ) , Pb ( 0.03 ppm ) , Cu ( 0 , 05 ppm ) , Al ( 94.20 ppm ) and Na ( 19.21 ppm ) . Eruption dust contained in the plant were also analyzed the concentration of heavy metals by extracting the leaves of the plant cabbage , red chili , Dutch eggplant , tomatoes , and citrus leaves prey . The result of heavy metal concentrations were obtained as follows : cabbage ( 0.56 ppm Fe , Mn 0.189 ppm , 0.133 ppm Zn , Pb was not detected , 0,019 ppm Cu , Al 0.45 ppm , 0.15 ppm Na ) ; Red pepper plant ( 0.10 ppm Fe , Mn 0,014 ppm , 0,017 ppm Zn , Pb 0.016 ppm , 0.04 ppm Cu , Al 0.024 ppm , 7.11 ppm Na ) ; Dutch eggplant plant ( 0.28 ppm Fe , Mn 0.012 ppm , 0.019 ppm Zn , Pb 0.03 ppm , 0,002 ppm Cu , Al 0.25 ppm , 6,757 ppm Na ) ; Tomato plants ( 0.39 ppm Fe , Mn 0.002 ppm , 0.044 ppm Zn , Pb 0.017 ppm , 0.021 ppm Cu , Al 0.186 ppm , 6.857 ppm Na ) ; Plant leaves prey ( 0.26 ppm Fe , Mn 0.033 ppm , 0.015 ppm Zn , Pb 0.017 ppm , 0.004 ppm Cu , Al 0.337 ppm , 7.157 ppm Na ) ; Citrus plants ( Fe 0.208 ppm , 0.018 ppm Mn ,, 0,021 ppm Zn , Pb 0.03 ppm , 0,009 ppm Cu , Al 0.123 ppm , 7.15 ppm Na ) .

Kadar logam berat yang terkandung di dalam debu hasil erupsi gunung Sinabung di tanah karo telah dianalisa, acuan logam-logam berat yang dianalisa antara lainlogam Fe ,Mn , Zn , Pb , Cu , Al dan Na. Masing-masing logam berat pada sampel debu erupsi selanjutnya diukur konsentrasinya menggunakan alatInductively Coupled Plasma (ICP). Masing-masing konsentrasi logam berat pada sampel debu erupsi diperoleh sebagai berikut : Fe (37,06 ppm), Mn (0,20 ppm), Zn (1,76 ppm), Pb (0,03 ppm), Cu (0,05 ppm), Al (94,20 ppm) dan Na (19,21 ppm). Debu erupsi yang terdapat pada tanaman juga turut dianalisis konsentrasi logam beratnya dengan cara mengekstraksi bagian daun dari tanaman Kol, Cabai merah, terong belanda, tomat, daun prey dan jeruk. Hasil uji konsentrasi logam berat yang diperoleh sebagai berikut: tanaman kol (Fe 0,56 ppm , Mn 0,189 ppm, Zn 0,133 ppm, Pb tidak terdeteksi, Cu 0,019 ppm, Al 0,45 ppm, Na 0,15 ppm); Tanaman cabai merah (Fe 0,10 ppm, Mn 0,014 ppm, Zn 0,017 ppm, Pb 0,016 ppm, Cu 0,04 ppm, Al 0,024 ppm, Na 7,11 ppm); Tanaman terong belanda (Fe 0,28 ppm, Mn 0,012 ppm, Zn 0,019 ppm, Pb 0,03 ppm, Cu 0,002 ppm, Al 0,25 ppm, Na 6,757 ppm); Tanaman tomat (Fe 0,39 ppm, Mn 0,002 ppm, Zn 0,044 ppm, Pb 0,017 ppm, Cu 0,021 ppm, Al 0,186 ppm, Na 6,857 ppm); Tanaman daun prey (Fe 0,26 ppm, Mn 0,033 ppm, Zn 0,015 ppm, Pb 0,017 ppm, Cu 0,004 ppm , Al 0,337 ppm, Na 7,157 ppm); Tanaman jeruk (Fe 0,208 ppm, Mn 0,018 ppm,, Zn 0,021 ppm, Pb 0,03 ppm, Cu 0,009 ppm, Al 0,123 ppm, Na 7,15 ppm).
