Abstract

Self-Nano-Emulsifying Drug Delivery System (SNEDDS)/ZnxFe3-xO4 has been successfully formulated through the synthesis of ZnxFe3-xO4 by the coprecipitation method and SNEDDS/ZnxFe3-xO4 by the sonication method. This study is focused on the effect of Zn doping on the crystal structure and antioxidant performance of ZnxFe3-xO4 nanoparticles. ZnxFe3-xO4 samples were characterized using FTIR and XRD to determine the functional groups and structure of the sample, respectively. SNEDDS/ZnxFe3-xO4 samples were characterized using FTIR and Antioxidants with the DPPH method to determine the functional groups and antioxidants in the sample, respectively. The FTIR characterization results of the ZnxFe3-xO4 sample showed the emergence of Zn-O and Fe-O functional groups in the wave number range of 825-869 cm-1 and 560-594 cm-1, respectively. This indicates that Zn2+ doping was successfully synthesized and shifted the Fe3+ ion. The IR spectrum also shows that the higher the concentration of Zn2+ ions, the more significant the change in absorption intensity, indicating that more molecules absorb light at wave numbers of 825-869 cm-1. The XRD characterization results show that the ZnxFe3-xO4 nanoparticle structure is an inverse cubic spinel occupying the Fd3m crystal group. Based on the analysis of XRD data, the higher the concentration of Zn2+ doping, the smaller the size of the ZnxFe3-xO4 nanoparticles produced. The diffraction peak of the sample on the 311 plane shifts towards a smaller angle due to the effectiveness of Zn2+ ion doping, shifting the Fe3+ ion because the radius of the Zn2+ ion is larger than the Fe3+ one. The antioxidant performance analysis of SNEDDS/ZnxFe3-xO4 showed inhibition potential ranging from 11% to 15%, increasing with higher Zn²⁺ concentrations.

Abstract

Salah satu daerah yang rawan terkena banjir berdasarkan data Badan Penanggulangan Bencana Daerah (BPBD) Kota Malang adalah Kelurahan Gadingkasri, Kecamatan Klojen, Kota Malang. Kelurahan ini memiliki bangunan rumah yang padat terdiri dari rumah penduduk hingga kos-kosan untuk mahasiswa dan pendatang. Kepadatan tersebut menyebabkan daerah ini sering mengalami bencana banjir pada musim penghujan ketika curah hujan tinggi. Oleh karena itu, perlu adanya teknologi rekayasa yang dapat dimanfaatkan untuk menanggulangi kejadian tersebut, salah satunya membuat lubang resapan biopori-smart light untuk mengurangi debit air pada saat curah hujan tinggi dan sekaligus menjadi penerangan jalan. Teknologi ini sangat efektif diaplikasikan pada lahan sempit dan juga dapat digunakan sebagai bahan pencahayaan yang hemat energi karena menggunakan tenaga cahaya matahari. Lampu biopori dilengkapi dengan katoda dan anoda yang tersimpan didalam biopori.

Abstract

This study successfully synthesized Magnetic Iron Oxide Nanoparticles (MIONs) through two different processes, namely mechanical synthesis (MIONs – M) and chemical synthesis (MIONs – N). The synthesized samples were characterized using X-Ray Fluorescence (XRF), Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), and Vibrating Sample Magnetometer (VSM) to determine the elemental composition, morphology, structure, and magnetization of the samples. XRF analysis revealed that iron (Fe) dominated both samples, with concentrations reaching 93.91% for MIONs – M and 89.91% for MIONs – N. SEM morphological analysis showed that the MIONs tended to be spherical and experienced agglomeration, with particle size distribution around 120 nm for MIONs – M and 30 nm for MIONs – N. XRD data indicated that both samples exhibited a cubic spinel Fe3O4 phase, consistent with the AMCSD 0000945 model data. Using the refinement method and Debye-Scherrer equation, the crystallite size and density of MIONs – M were found to be larger than MIONs – N. This correlates with VSM data analysis, where the saturation magnetization of MIONs – M (49.51 emu/g) was greater than that of MIONs – N (26.54 emu/g). These results provide important insights into the characteristics of MIONs and their implications for technological and industrial applications.
