“…The next step is titrated with an NH4OH solution and processed using a hot plate magnetic stirrer. The titration result was washed with distilled water until it reached normal pH (pH 7) which was then filtered using filter paper with a certain mess scale and then heated in the oven at 100 ºC for an hour [26].…”

The aim of this research is to identify the crystal structure, surface area, and magnetic properties of The Mn0.25Fe2.75O4-rGO (reduced Graphene Oxide) nanocomposites (NCs). The synthesis of Mn0.25Fe2.75O4-rGO nanocomposites used the co-precipitation method. The rGO was obtained from the chemical reduction of GO by hydrazine hydrate as the reduction agent. The ratio between Mn0.25Fe2.75O4 nanoparticles and rGO was 1:1 that ultrasonicated at 200 Hz for an hour. The IR spectra of NCs from the FTIR instrument showed that the absorption band around 580 cm-1 and 1622 cm-1 corresponds to the stretching mode of Fe-O and C=C respectively. According to X-Ray Diffraction (XRD) pattern analysis, peak of Mn0.25Fe2.75O4 was detected on 2θ at 30.1°, 35.5°, 53.5°, 57.1°, 62.7° and the peak of rGO phases was amorphous that detected on 2θ between 17º and 30º. The XRD pattern analysis and FTIR spectra have proved the completion of NC’s synthesis. The crystallite size was between 10.3 nm by Scherer's formula. The Specific Surface Area showed that the surface area of the nanocomposites was 100.61 m2/g and the Molecular cross-sectional area was 0.162 nm2 by BET Theory. The Magnetic properties show that the NCs were Superparamagnetic material that has a saturation magnetization of 9.34 emu/g. The material has many potentials to be explored by the researcher around the world.

“…Introduction Corncobs are one of the agricultural waste biomass that can be used as an adsorbent to remove pollutants. This agricultural waste can bind heavy metals by adsorption, chelation (chelating), and ion exchange [1]. In addition, corncobs contain chemical components such as cellulose, hemicellulose, and lignin.…”

This study aims to identify and analyze the band gap width of the carbon phase produced from corncobs mixed with PEG-4000 to see the surface area of the corncob carbon phase. First, the characterization test was carried out using Scanning Electron Microscope Energy-Dispersive X-ray (SEM-EDX) spectroscopy to determine the morphology and Ultraviolet-Visible (UV-Vis) spectroscopy to determine the band gap width of corncob carbon. Then, adding Polyethylene Glycol (PEG) 4000 at a specific concentration to develop the potential of corncob carbon. Finally, the corncob-PEG 4000 carbon reduction process was sifted through and tested by UV-Vis spectroscopy, and the energy gap value was 0.954 eV.

In general, the increase in textile industry development has a negative impact on water pollution, especially related to textile waste that usually contains toxic dyes such as methylene blue. The filtration membrane was fabricated using the phase inversion method from the Mn0.1Fe2.9O4/graphite nanocomposite incorporated with polyether sulfone (PES) as a membrane. The Mn0.1Fe2.9O4/graphite was synthesized using Indonesian iron sand and coconut shells. The X-ray diffraction pattern showed that the nanocomposite was composed of a crystalline phase with the highest peaks appearing at 2θ = 26° and 35.6°, corresponding to the peaks of graphite and Mn0.1Fe2.9O4, respectively. Furthermore, the Fe-O and C=C functional groups from the Fourier-transform infrared spectrum confirmed the presence of respective Mn0.1Fe2.9O4 and graphite. The hysteresis curve showed that the Mn0.1Fe2.9O4/graphite nanocomposite had a superparamagnetic character. The membrane showed good performance for filtering methylene blue as indicated by a water flux value of 158.86 Lm-2h-1. These results show that nanocomposite-based membranes have great potential to be applied as methylene blue filters.
