Abstract

Plastic waste has become a global problem because it causes environmental pollution. This isbecause plastic waste is difficult to decompose. There have been numerous solutions proposed, one of which is theuse of bioplastics. In this research, the bioplastics were made from third-generation biomass, namely the eucheuma cottoni. Eucheuma cottoni is contains biopolymer carrageenan,a carbohydratewith unit structures consisting of d-galactose and 3,6 anhydro galactosewith glycosidic bonds. Goal thisresearch is study the effects of sorbitol plasticizer content and bioplastics manufacturing temperature on bioplastics, tensile strength, elongation, and biodegradation rate. The bioplastics were made by extracting 10 grams of eucheumacottonipowderin200mlofdistilledwater.Thealgaeextractwasaddedwithsorbitol (plasticizer) and heated at various temperatures from 45°C until 60°C. The mixture was poured into a mold tin and dried in the oven to a constant weight. The resulting bioplastics were then characterized to determine the tensile strengt hand biodegradation rate.Theresultsshowedthat increasing the plasticizer content from 3.5% reduced the tensile strength, however, it increased the elongation and biodegradation rate. The optimal plasticizer content was 4% with a tensilestrength value of 4.8309 Mpa, elongation of 24.1548%, and biodegradation rate of 26.9392%.The temperature variable showed that increasing the temperature of making bioplastics couldreducetensilestrength,increaseelongationandbiodegradationrateofbioplastics.Theoptimum temperature for making bioplastics at 45oC obtained a tensile strengthof6.28 Mpa and an elongation of 20.67%. The biodegradation rate was 39.6665%, and the best sorbitol content was received at 4%
