Microwave co-pyrolysis between biomass and plastics is a promising endeavor in producing high-quality fuels. This study aims to evaluate the combustion characteristics of briquettes using the Thermogravimetry analysis (TGA) method, including Initiation Temperature of Volatile Matter (ITVM), Initiation Temperature of Fixed Carbon (ITFC), Peak of weight loss rate Temperature (PT), Burning out Temperature (BT), Energy activation (EA), and mass loss rate (MLR). The results showed that the value  of ITVM, ITFC, and PT increased as the briquette pressure increased, while the value of ITVM, ITFC, and PT decreased as LDPE plastic increased in the composition of the charcoal mixture.
