The plant’s wastes can be recycled as a source of natural fiber to fabricate biodegradable films. The utilization of natural waste cornhusk for the production of environmentally friendly mulch was studied. The cellulose of cornhusk can be extracted with alkali treatment so that the cellulose produced can be used as a material for mulches. The mulch film can be synthesized with a variation content of cornhusk cellulose at 5,10, and 15 %, Low Linear Density of Polyethylene (LLDPE), variations in anti-UV concentration (1,4, and 6 %) and the addition of additives using the extrusion-calandering method. Variations in the added anti-UV concentration could affect the optical and mechanical properties of the mulch film produced. The mulches film produced has a black color, smooth and elastic surface. The mechanical properties of the film have increased. Significant tensile strength 20.75 MPa, elongation 354 % and modulus of elasticity 0.62 GPa were found in films with the addition of 4 % tinuvin concentration and 15 % cellulose content. The addition of anti-UV resulted in a shift in the peak in the UV range so that no dominant peaks appeared for T1, T4, and T6 mulches. The mulches film T4 at 5 % cellulose content absorbs maximum light at a wavelength of 300-400 nm. SEM analysis showed that the homogeneous mulch film morphology has a lump and is porous.
