Abstract:

The accumulation of plastic waste and rice husk waste is a serious problem for the environment, even though both types of waste have good characteristics and have the potential to be used as new materials. Thermal pretreatment with the torrefaction method is one of the options to overcome the problem of accumulation of both types of waste. The purpose of this research is to make functional materials from LDPE plastic as a matrix and rice husk waste as a filler through the torrefaction method. The rice husk was dried in an oven at 70°C for 1 hour, then blended until smooth and filtered using a mesh 60 sieve. Rice husk was mixed with LDPE plastic in the mold before the torrefaction process with variations of holding time of 30 minutes, 60 minutes, and 90 minutes. After the torrefaction process, the material that had been formed was then tested to determine its characteristics. The highest tensile strength was obtained at a holding time of 30 minutes with a tensile strength of 8.06 N/mm2. The highest impact strength was obtained at a holding time of 30 minutes with an impact strength of 13.61 J/mm2. The lowest water absorption was obtained at a holding time of 60 minutes with a water absorption of 1.06%. The use of plastic waste and rice husks in producing new materials shows good characteristics as functional materials, while also having the potential to reduce the accumulation of waste which is a global threat.
