“…The curve showed a hysteresis loop with a high saturation magnetization of 27.8, a remanent magnetization of 2.34 and a coercive field of 21.3. Furthermore, the hysteresis curve shows a narrow curve area, indicated that the iron sand is a typical soft magnetic material [20]. The low coercivity and paramagnetic-like behavior was known as the typical hysteresis curve of commercial magnetite [21].…”

In this study, we investigated the mineral content and magnetic properties of river iron sand from Jayapura, Papua. The iron sand was collected from the Waimbow River in the Waibu District, whereas the bulk samples were extracted using a permanent magnet. The extracted iron sand was characterized using X-ray fluorescence and X-ray diffractometer to identify the elemental composition and structural phase. Meanwhile, the vibrating sample magnetometer was also applied to characterize the magnetic properties. The results show that the iron sand contains magnetite as a major mineral, with soft magnetic properties. The hysteresis curve shows that the iron sand has a high saturation magnetization of 27.8 emu/g, remanent magnetization of 2.34 emu/g, and coercive field of 21.3 Oe. These results also indicate that the iron sand formation in northern Papua was mainly due to lithogenic factors.

“…The result of energy spectra as shown in figure 6 shows that the most dominant element of the nanoparticle is oxygen (O) and iron (Fe) which were consecutively in 0.5 keV and 6.4 keV energy with Kwavelength. It means that the extraction of Fe3O4 nanoparticle has successfully separatedd the iron Fe from other impurities and successfully coated using PEG 4000 (Gunanto et al, 2018).…”

Fe3O4 encapsulated PEG form iron sand at wari ino beach has been successfully synthesized by co-precipitation method. The average particle size of the nanoparticle 11,3 nm was determined by scherrer formula. Fe3O4 modification PEG 4000 was successfully encapsulated the samples by the presence C-O-C and CH bonding that were characterized using Fourier Transform Infra Red (FTIR), X-Ray Diffraction (XRD) pattern shows that all samples are formed by single phase cubic spinel magnetite , and Scanning Electron Microscopy (SEM) shows the high dispersion capability while encapsulated process using PEG. The results of the characterization show that the Fe3O4 successfully encapsulated by PEG 4000.

Abstrak Fe3O4 adalah material magnetik dan termasuk dalam kelompok besi oksida. Fasa yang terbentuk pada material yaitu magnetit serta memiliki potensi dalam berbagai bidang seperti kedokteran dan industri, potensi tersebut muncul apabila material berukuran nano yaitu 1-100 nm. Tujuan dari penelitian ini adalah (1)menganalisis fasa yang terbentuk pada sampel menggunakan software match! dan (2)menganalisis ukuran kristal Fe3O4 menggunakan persamaan Scherrer. Pasir mineral wilayah Tulungagung, Jawa Timur merupakan salah satu bahan alam yang dapat digunakan dalam sintesis Fe3O4 karena memiliki komposisi unsur besi 86%. Namun pengetahuan masyarakat yang kurang mengenai manfaat pasir mineral menyebabkan bahan tersebut kurang dimanfaatkan secara maksimal sehingga berdampak pada harga jual yang rendah. Dalam kondisi tersebut mendorong peneliti untuk memanfaatkan bahan alam tersebut menjadi material multifungsi seperti Fe3O4. Kopresipitasi merupakan contoh metode yang digunakan dalam sintesis Fe3O4, keunggulan dari metode tersebut diantaranya tidak membutuhkan waktu yang lama, menggunakan suhu ruang dalam percobaan dan biaya operasional relatif terjangkau. Hasil uji X-Ray Diffraction (XRD) yaitu didapatkan sudut 2 theta optimum sebesar 35,42° dengan orientasi kristal (311), sudut tersebut menunjukkan material memiliki fasa magnetit karena sesuai dengan data Join Committee On Powder Diffraction Standard (JCPDS) no. 19-0629 dan diketahui telah terbentuk ukuran nanopartikel yang dihitung dengan persamaan Scherrer sebesar 8,57 nm. Kata Kunci: Pasir mineral, Fe3O4, metode kopresipitasi. Abstract Fe3O4 is a magnetic material and belongs to the iron oxide group. The phase formed in the material is magnetite and has potential in various fields such as medicine and industry, the potential arises when the material is nano-sized which is 1-100 nm. The purpose of this study is (1)to analyze the phases formed in the sample using match! and (2)analyzing Fe3O4 crystal size using the Scherrer equation. mineral sand Tulungagung region, East Java is one of the natural materials that can be used in the synthesis of Fe3O4 because it has an 86% iron element composition. However, the lack of public knowledge about the benefits of mineral sand causes the material to be underutilized to the maximum, resulting in a low selling price. These conditions encourage researchers to utilize these natural ingredients into multifunctional materials such as Fe3O4. Coprecipitation is an example of the method used in the synthesis of Fe3O4, the advantages of this method include not requiring a long time, using room temperature in the experiment and relatively affordable operational costs. The X-Ray Diffraction (XRD) test results obtained an optimal theta angle of 35.42° with a crystal orientation (311), the angle indicates the material has a magnetite phase because according to the Committee to Join the Powder Diffraction Standard (JCPDS) number 19-0629 and it is known that the size of the nanoparticles calculated by the Scherrer equation is 8.57 nm. Keywords: Mineral sand, Fe3O4, coprecipitation method.
