Microplastic waste is a slight waste of about 1 micrometer to 5 millimeters. This microplastic comes from the decomposition of plastic waste that is larger in size, where later the plastic waste will never be wholly decomposed, resulting in microplastic waste. Some efforts from the industry to remove microplastics from aquatic media, but it takes a long time and is expensive due to high energy requirements, such as thermal, catalytic, mechanical, chemical, ozonation, and photo-oxidation degradation. For this reason, magnetic materials are needed as microplastic absorbents in water. The material can be extracted from Tulungagung natural sand containing magnetic Fe3O4, ilmenite 86%. The Fe3O4 synthesis method uses coprecipitation, the results of which can be characterized by XRD, FTIR, and SEM. The results showed that Fe3O4 has a magnetic phase with a crystal structure of 8.57 nm, has functional groups Fe-OH and Fe-O, and a grain size of 44.03 ± 0.81 nm with a spherical shape. The existence of Fe3O4 from this synthesis is expected to be used as a preparation for later use as a microplastic absorbent. © 2024 Author(s).
