“…The mixing of the two ingredients between the barium hexaferrite precursor and betel leaf extract can be done using a microemulsion method Koutzarova et al, 2013, solid-state, coprecipitation Alonso-Rodríguez et al, 2020, sol-gel Mosleh et al, 2016and hydrothermal synthesis (Zhao et al, 2013. In general, the things that need to be considered in some of these methods are the percentage of the mixture of materials, the calcination process, compaction, and sintering (Rusianto et al, 2015). A literature review of synthesis methods with the addition of plant extracts and compounds to ferritebased magnets can be seen in Table 3.…”

Betel leaf is a typical Indonesian herbal plant that propagates on other tree trunks. So far, betel leaf has only been used in biomedicine and traditional medicine, whereas the chemical compounds of betel leaf can be used to absorb electromagnetic waves. In this mini-review, we review several research results to discuss the potential effectiveness of betel leaf in barium hexaferrite as an absorber of electromagnetic radiation. We compiled this mini-review based on the literature review method that is discussed extensively and in-depth regarding the chemical composition of betel leaf, modification of the development of barium hexaferrite material with betel leaf media extract, characteristics of BaFe12O19 as absorption of electromagnetic waves, and the effectiveness of media extracts in BaFe12O19 as absorption of electromagnetic waves. Based on the results of the literature review, the modification of BaFe12O19 material synthesis can include microemulsion, solid-state, coprecipitation, sol-gel, and hydrothermal synthesis. So far, hydrothermal synthesis is a synthesis method of mixing betel leaf extract media and ferrite-based magnets that have been studied before. Betel leaf in ferrite-based magnetic materials has been studied not to damage the surface morphology and characteristics of the magnetic material. The results of the assessment also show the effectiveness of adding other elements or compounds such as Ni, Al2O3, and composites in ferrite-based magnetic materials that can absorb more than 90% of electromagnetic waves in the frequency range 2-18 GHz.

In this research, the manufacture of barium hexaferrite (BaFe12O19) magnetic ceramics and the addition of titanium dioxide (TiO2) additives with variations of 0%: 0.3%: 0.6% and 0.9% used the powder metallurgical method. The characterization used in this study is the measurement of density, porosity, X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Vibrating Sample Magnetometer (VSM), and Impulse Magnetizer K-Series. Based on the results of density and porosity measurements, the highest values were 4.95 g/cm3 and 5.45%, respectively. XRD results showed the formation of a BaFe12O19 phase with some impurities at 0% (Fe2O3), 0.3% and 0.9% (Ti6O11), and 0.6% (Ti4O7). The SEM results showed that the morphology of TiO2-BaFe12O19 was quite homogeneous, and the size and cavity ranged from 0.5 – 1.5 μm and 0.25 – 0.9 μm, respectively. VSM results show Mr, Ms, Hc, and Bhmax values of 1,489 kG, 3,235 kG, 1,758 kOe, and Bhmax of 0,867 MGOe, respectively. The results of the Impulse Magnetizer K-Series show the maximum and lowest magnetic flux values of 272.65 gauss and 218.10 gauss at 0.6% and 0% variation, respectively.
