dc.description.abstractCellulose can be processed into a hydrogel that enhances performance in extinguishing Class B (oil) fire. This hydrogel has a significant increase in viscosity after exposure to high temperatures. As the temperature increases, the viscosity rises, enhancing the ability of hydrogel to coat the fuel surface and effectively prevent the production of flammable vapor. Therefore, this study aimed to synthesize cellulose-based hydrogel by extracting water hyacinth to obtain cellulose in the form of methylcellulose (MC) powder. Properties of cellulose hydrogel were tested using Fourier Transform-Infrared Spectrometer (FT-IR), Scanning Electron Microscope (SEM), Energy Dispersive X-Ray Spectroscopy (EDX), viscosity, Thermogravimetric Analysis (TGA), and gel fraction analysis. To define its performance, fire extinguishing efficiency tests were performed by comparing mono-ammonium phosphate (MAP) or ABC (control) and MAP+ cellulose hydrogel (treatment). The data obtained were the radiation temperature, the time required to extinguish fire, and characteristics of the fuel coating during combustion. The results showed that fire extinguishing performance for Class B fire, in terms of radiation temperature, was lower for MAP+cellulose Hydrogel at 284.67±39.28°C, compared to MAP at 368.10±51.46°C. Extinguishing time for the MAP+ Cellulose Hydrogel was 4.19 seconds faster than only MAP. Additionally, the coating properties improved as the substance transitioned from powder to gel, effectively coating the fuel at high temperatures. This was consistent with the results of the Gel Fraction Analysis and TGA, which prevented fire spread and improved flame retardancy. © (2025), (Faculty of Engineering, Universitas Indonesia).
