Abstract

Nanopartikel magnetik Fe3O4 disintesis dari destruksi batuan besi. Metode yang digunakan adalah metode kopresipitasi dengan menggunakan template PEG 4000. Penelitian ini bertujuan untuk menganalisis pengaruh waktu pemanasan terhadap sifat nanopartikel magnetik yang dihasilkan, yaitu 3 jam, 4 jam, dan 5 jam pada temperatur 220 0C. Karakterisassi nanopartikel magnetik dilakukan dengan Magnetic Susceptibilitymeter, X-Ray Difractometer (XRD), dan Scanning Elektron Microscope (SEM). Berdasarkan hasil penelitian ini, waktu dan temperatur pemanasan berpengaruh terhadap kemagnetan, ukuran partikel, maupun ukuran kristal material magnetik Fe3O4 yang dihasilkan. Pemanasan dengan waktu yang optimum diperoleh pada 4 jam dengan ukuran kristal 20,86 nm dan ukuran partikel terkecil antara 36-46 nm dan suseptibilitas magnetnya 20427,96 m3 /kg. Sedangkan distribusi ukuran partikel sudah cukup seragam dan berbentuk bulat, sebagai pengaruh dari PEG 4000 yang berfungsi sebagai template dan mencegah terjadinya aglomerasi antar partikel.
