Abstract

Telah dilakukan identifikasi mineral magnetik tanah permukaan berdasarkan pengukuran nilai suseptibilitas dan analisa X-Ray Diffraction (XRD) di Desa Kahuripan Baru Kabupaten Muara Enim. Tujuan utama dari penelitian ini adalah mengetahui nilai suseptibilitas tanah dan jenis mineral serta komposisi mineral yang terkandung di daerah penelitian. Pengukuran suseptibilitas dilakukan dengan menggunakan alat Bartington Suseptibilitymeter sedangkan karakterisasi dengan metode X-Ray Diffraction (XRD). Dari hasil pengukuran suseptibiltas diperoleh nilai tertinggi berada pada sampel A3 dengan suseptibiltas 1814,03× 10^(-8) m^3/kg dan terendah pada sampel P2 dengan suseptibilitas 20,20× 10^(-8) m^3/kg. Berdasarkan perhitungan Frequency Dependent diketahui jenis mineral dominan daerah penelitian adalah superparamagnetik. Dari nilai suseptibilitas dan analisa X-Ray Diffraction diketahui mineral yang paling dominan pada daerah penelitian adalah ilmenite. Hal ini diduga pada daerah penelitian ini usia tanaman mempengaruhi pertumbuhan tanaman, semakin lama usia tanaman maka pertumbuhan akarnya semakin panjang dan banyak, seperti tanaman karet yang berakar tunggang dan merambat secara lateral, yang menyebabkan tingginya nilai suseptibilitas.
