Telah dilakuan sintesis nanopartikel Fe3O4 dari batuan besi menggunakan metode kopresipitasi dengan penambahan asam laurat sebagai zat aditif. Variasi massa asam laurat yang diberikan adalah 0 g, 5 g,   10 g, 20 g, dan 30 g. Karakterisasi sampel yang dilakukan meliputi karakterisasi morfologi permukaan sampel menggunakan SEM dan ukuran kristal menggunakan XRD. Hasil karakterisasi menggunakan XRD menunjukan ukuran kristal sampel tanpa penambahan asam laurat adalah sebesar 120 nm dan penambahan 10 g asam laurat adalah 46 nm. Hasil karakterisasi SEM menunjukan distribusi partikel yang paling seragam didapatkan pada sampel dengan penambahan asam laurat sebanyak 30 g dengan ukran partikel berkisar antara 58-77 nm.
