Abstract

Sampel tanah lapisan atas diambil di sepanjang jalan disekitar suatu pabrik semen di kota Padang pada 28 titik yang terbagi atas 3 lintasan. Untuk setiap titik, sampel tanah diambil pada kedalaman 10 cm sebanyak 100 g. Pengukuran nilai suseptibilitas magnet menggunakan Bartington MS2B Magnetic Susceptibility Meter. Konsentrasi enam jenis logam-berat yaitu Cu, Cd, Pb, Zn, Al, dan Cr ditentukan dengan Atomic Absorption Spectrometry. Dari penelitian ini diketahui bahwa: nilai rata-rata suseptibilitas magnetik sampel adalah 1.196,5x 10-5 m3kg-1 dengan rentang nilai mulai dari 429,5x10-5 m3kg-1 sampai 3.560,0x10-5 m3kg-1 ; kadar semua jenis logam berat dalam tanah lapisan atas di area penelitian ini relatif tinggi (rata-rata > 35,7 ppm); kadar logam berat yang ada dalam tanah lapisan atas di area penelitian ini didominasi oleh logam Al; secara umum urutan konsentrasi logam berat dari yang paling besar sampai yang paling kecil hampir sama di seluruh area yaitu Al, Zn, Cu, Cd, Cr, Pb; dan tidak teramati pengaruh jarak dari pabrik semen terhadap nilai suseptibilitas maupun konsentrasi setiap jenis logam berat.
