“…Iron sand in nanopedic sizes has many application opportunities in industry, electronics and medical [5], Earth magnetism studies [6][7] and defence as anti-radar materials [8]. Ref [9] has been synthesize of Fe3O4 nanoparticles from nature iron sands take from Buaya River in Deli Serdang, North Sumatra by co-precipitation method. So far, iron sand research is only done on the beach, such as research on the magnetic properties of iron sand by Ref [10] in Sunur Beach, Pariaman, W and Ref [11] at Air Tawar Beach Padang Sumatera Barat.…”

Iron sand is one of the natural resources in West Sumatra that has not been optimally utilized. One of the potential locations to get this iron sand deposits is the coast of Kata. This study aims to analyze the content and size of the iron grains found on the coast of Kata Padang Beach, West Sumatera Province. Coastal sand samples are extracted using permanent magnets to separate magnetic and non-magnetic materials. Characterization of iron sand using Scanning Electron Microscopy with Energy Dispersive X-ray (SEM-EDX) and Vibrating Sample Magnetometer (VSM). The result of characterization using SEM-EDX shows that iron sand samples contain Fe and O elements derived from Phase Magnetite (Fe3O4). Keywords: iron sand, magnetic materials, SEM-EDX, VSM

“…Pasir besi diambil di Pantai Sampulungan Kabupaten Takalar pada 30 titik. Masingmasing titik pasir besi diambil pada kedalaman 1 m. Pasir besi dicuci, dikeringkan pada suhu kamar, diseparasi menggunakan magnet batang (Sunaryono, et al, 2015;Setiadi, et al, 2016), diayak menggunakan ayakan 100 mesh, dan ditimbang sebesar 10 g. Selanjutnya, pengukuran suseptibilitas magnetik dilakukan pada sampel menggunakan Bartington MS2 Susceptibility Meter (Bartington Instrument Ltd., Oxford, United Kingdom) dilengkapi sensor MS2B yang bekerja pada dua frekuensi (470 Hz and 4700 Hz). Data suseptibilitas magnetik pada frekuensi rendah menggunakan data sekunder.…”

Telah dilakukan penelitian mengenai kajian suseptibilitas magnetik bergantung frekuensi terhadap pasi besi Kabupaten Takalar. Tujuan penelitian ini adalah mengidentifikasi mineral magnetik yang dominan berdasarkan data suseptibilitas magnetik dan menganalisis sumber mineral magnetik berdasarkan suseptibilitas magnetik bergantung frekuensi. Metode yang digunakan adalah metode magnetik batuan khususnya parameter suseptibilitas magnetik. Pengukuran dilakukan menggunakan alat Bartington MS2 Susceptibility Meter dilengkapi sensor MS2B yang bekerja pada frekuensi rendah (470 Hz) dan frekuensi tinggi (4700 Hz). Hasil penelitian mengindikasikan pasir besi mengandung mineral ferrimagnetik yaitu magnetite. Nilai suseptibilitas magnetik pada frekuensi rendah dan frekuensi tinggi identik serta persentase suseptibilitas magnetik bergantung frekuensi diperoleh kurang dari 2 % yang mengindikasikan pasir besi memiliki bulir magnetik multi domain (MD). Korelasi positif antara suseptibilitas magnetik pada frekuensi rendah dengan bergantung frekuensi mengindikasikan sumber mineral magnetik yang dominan berasal proses pedogenik yaitu pelapukan batuan gunung api.

“…Dua fasa baru ini muncul akibat adanya penambahan Fe3Mn7 yang ditambahkan dan telah mengalami perubahan fasa akibat perlakuan termal. Fasa MnO2 merupakan oksida mangan dengan struktur oktahedral dengan parameter kisi a = 9,322 Å, b = 4,453Å dan c = 2,848 Å, sedangkan Fe3O4 merupakan fasa dengan struktur kubik dengan parameter kisi a = b = c = 8,39 Å [9].…”

Proses pencampuran serbuk α-Fe2O3 dan Fe3Mn7 dilakukan dengan menggunakan HEM. ºKemudian campuran serbuk dikasinasi pada suhu 1000C, dikompaksi pada 69 Pa hingga menjadi pellet dan disinter padasuhu 1000 ºC. Karakterisasi XRD menunjukkan adanya fasa dominan α-Fe2O3 dan fasa baru MnO2 dan Fe3O4. Densitas dankekerasan sampel meningkat secara linier seiring dengan kenaikan komposisi Fe3Mn7 yang ditambahkan. Sampel optimum3diperoleh pada sampel α-Fe2O3/10 %wt. Fe3Mn7 dengan nilai bulk density dan kekerasan masing-masing 4,98 g/cm and994,94 HV. Sampel ini termasuk dalam klasifikasi hard magnet dengan nilai magnetisasi saturasi, remanen dan koersivitasmasing-masing sebesar 24,0 emu/g, 10,3 emu/g dan 571,8 Oe.Kata kunci:. α-Fe2O3, Fe3Mn7, densitas, kekerasan, sifat magnetikAbstract: Preparation and characterization of α-Fe2O3 pellet with the addition of 0, 2, 5 and 10 %wt. Fe3Mn7 based on naturalmaterials have been successfully carried out. The process of mixing powder of α-Fe2O3 and Fe3Mn7 was performed usingºHEM.
