The research improves the strength of plastic using avocado seed starch and PLA. effect blending PLA was optimized RSM approach by two variables: water absorption biodegradability. Mixing them gave best result: 1.8 g 3 Degradable has a (tensile 10.1 MPa; elongation at break 85.8%; young modulus 190 MPa). Infrared spectroscopy showed that had -OH bond 3273.20 cm-1, 3502.73 3647.39 CH2 2953.52 2945.30 2902.87 C=C 1631.78 C-O 1741.72 cm-1. decomposed in soil. It organic hydrophilic. Thermal tests, can withstand heat well, losing weight 356.86°C to 413.64°C, forming crystals melts 159.10°C—the same as Melt flow test, sample before measurement, therefore not measurable—process conditions affect. Water 5.763% biodegradation rate 37.988% for 12 days. In morphology analysis, fused form smooth surface. found value close 1. process parameters.
