Abstract

Water pollution affects life sustainability; hence, several efforts have been exerted to overcome this problem. For ex-ample, nanofiber membrane technology is introduced to retain solutes while allowing only water molecules to pass through the system. Therefore, this study aimed to maximize the technology for water filtration using the electrospin-ning method by combining Styrofoam waste-based polymer with activated carbon from coconut shell waste (ACCS). The nanofiber diameter produced ranged from 590 nm to 610 nm with porous characteristics and without beads. The carbon content varied from 68.04% to 69.84%, according to the energy dispersive X-ray measurement, demonstrating the composite’s effectiveness. The Fourier transform infrared spectroscopy results also indicated carbonization and activation, along with water removal, associated with O-H stretching vibrations of alcohol and phenol, as well as N-H stretching vibrations of amino bonds. Moreover, the mechanical properties were measured using a single-fiber tensile test on X-ray diffractometry (XRD) analysis, and Young’s modulus was successfully maintained at 3,209.15 ± 632.877 and 1,839.12 ± 212.637 kPa due to the material amorphous nature. The contact angles were 126.5° and 131°, demon-strating ultra-hydrophobic properties. The addition of ACCS has led to a superior porosity structure for waste filtration. The clean water permeability test also showed that the membrane can withstand a 1–4 bar pressure for 15–60 seconds, demonstrating its strength in resisting water resistance. The trend shows the capacity of the material to potentially func-tion as a superior candidate for water filtration.

Abstract

The electrospinning method has been used successfully to make polyvinylpyrrolidone nanofiber containing Anredera cordifolia leaves (BLE). The research methods used were qualitative and pure experiment method. Polyvinilpirolidone nanofibers containing BLE were prepared with three mass variations of the polyvinylpyrrolidone (% w/w), namely 12%, 10%, and 8% w/w, respectively. The results of the macroscopic photo show that the fiber structure looks white for PVP nanofibers and yellow for PVP/BLE nanofibers. The fiber morphology was analyzed using SEM and the results showed that PVP and all PVP/BLE nanofibers were like a continuous strand of crossbars with a diameter of 590 – 1190 nm. The decrease in the concentration of the PVP polymer led to a reduction in the diameter of the resulting nanofibers. The coefficients of variance (ε), of the PVP, BLE1, BLE2, and BLE3 nanofibers were 0.06, 0.09, 0.11, and 1.22, respectively. The physicochemical structure of the nanofibers was evaluated using XRD and FTIR. The chemical analysis (FTIR) showed that there was a molecular interaction between Anredera cordifolia leaves extract and polyvinylpyrrolidone in the form of hydrogen bonds. The physics analysis (XRD) shows the effect of the electrospinning process, which is to change the structure of BLE crystals to semi crystals. The application of PVP/BLE nanofiber for wounds dressing
