Abstract

In the digital era, the utilization of technology in the field of education has provided new opportunities to develop more interactive and exciting learning methods. This research aims to show the effectiveness of using android applications in measuring magnetic fields as physics learning media. This research was conducted using a quantitative approach and pure experimental method carried out at the Physics Science Laboratory of FKIP Untirta by comparing the results of direct magnetic field measurements and magnetic field measurements using android applications (Gauss Meter Keuwlsoft, Magnetometer, and Physics Toolbox Magnetometer). The results showed that there is effectiveness in using android applications as learning media in measuring magnetic fields in physics learning. This is evidenced in the results of data processing that are close to the results of direct measurement, where the farther the compass distance, the smaller the angle of deviation of the compass needle, indicating the more minor the magnetic field in that position. Android applications can be an effective learning environment for learning physics, one of which is about magnetic fields. This research has important implications for the integration of technology in education.

Abstract

A study was conducted to analyze the functional groups in green synthesized (GS) Fe3O4 samples using Moringa Oleifera (MO) and black iron oxide (Fe3O4) nanoparticles using FTIR-Spectroscopy. Functional group analysis of the samples was carried out to ascertain whether there was any difference in the formation of MNPs from the use of MO, molecular bonds were observed using FTIR spectra. The presence of magnetite nanoparticle absorption peaks showed two vibrational bands in the range of wave numbers 596-642 cm-1, which correspond to the stretching vibrations of the M-O (metal-oxide) bond. The absorption around 578 cm-1 corresponds to stretching vibrations on the tetrahedral sites of the metal (Fetetra-O). The formation of GS-Fe3O4 is strongly confirmed by the presence of characteristics similar to conventional Fe3O4 in the range of wave numbers 1391, 1633 and 2318 cm-1, which represent stretching vibrations of C=O, N-H, C=O chemical bonds, and another absorption peak at wave number 3167 cm-1 corresponding to vibrations of O-H (hydroxyl) groups.
