The synthetic plastic waste was the big problems for sustainable environmental. Many efforts to solve it by the incineration process and also developing bioplastics. Addition of nanomaterial into bioplastic as the reinforcement can affect their properties. This study aim was to show the influence of nanoclay on the thermal decomposition of the biocomposite matrix starch/carrageenan blend. This experimental research involved addition of nanoclay with concentration of 0%, 2.5%, 5%, 7.5%, and 10% into bioplastic. The casting methods with homogenizer ultrasonic were conducted to obtain biocomposite. The thermal degradation of biocomposite was observed using thermogravimetric analysis. The result indicate that reinforced nanoclay in the biocomposite matrix of starch/carrageenan blend show four phases of decomposition process which are phase I at the temperature until 145°C, phase II at the temperature from 146°C to 340°C, phase III at the temperature from 341°C to 475°C that indicate the transition of biocomposite into the char and phase IV at the temperature from 476°C to 700°C. © Published under licence by IOP Publishing Ltd.
