The use of UV Protection products that circulate in the community today can endanger human health. The use of rice husk waste which has high cellulose content and ivy nanoparticles that have properties that can protect the skin from sunlight can be used as a face mask that can protect the skin from UV exposure. The advantages of hydrogel masks are high humidity and safe for health. Hydrogel masks are produced from the synthesis of rice husk nanocellulose using the acid hydrolysis method, then hydrogel films are made using nanocellulose mixed with chitosan and ivy nanoparticles. The hydrogel film obtained was tested by swelling test to demonstrate the ability of the films to absorb and store water in its structure. Then, characterization tests were performed using TEM to determine the morphology of nanocellulose, SEM to observe the morphology and structure of the surface of the films formed, FTIR for the analysis of the functional groups contained, and UV-Vis spectroscopy for the analysis of anti UV properties in the hydrogel films. The morphology of nanocellulose is in form of fiber with the size of 16-50 nm. Chitosan-Nanocellulose (CH-CN), Chitosan-Nanocellulose-Ivy 0,25% (CH-CN-Ivy 0,25%), and Chitosan-Nanocellulose -Ivy (CH-CN-Ivy 0,5%) films have swelling degrees respectively 82,8%, 79,33%, and 72,81%. UV-Vis characterization carried out on both CH-CN-Ivy samples showed that ivy had a unique peak which showed peak ivy absorbance against UV light in the long range of UV rays (range 280-315 nm) with the absorbance of 0,814 for CH-CN-Ivy 0,25% film and 0,867 for CH-CN-Ivy 0,5% film. It can be concluded from data from the research that the three hydrogel films have swelling ability. Both CH-CN-Ivy films have anti UV properties.
