This study investigates an environmentally friendly bioplastic made from cornstarch with fructose and different amounts of titanium dioxide (TiO2). The research focuses on its physical, chemical bonding, and nutritional properties. X-ray diffraction analysis indicates that TiO2 influences diffraction peaks, affecting the crystal size, with the smallest size of 12.54 nm observed in Sample (II) containing 0.1 g of TiO2. Fourier transform infrared analysis shows slight shifts in the stretching of the-OH groups, indicating consistent elemental composition. The mechanical properties of the bioplastic for Sample (I) lacking TiO2 exhibits the highest Young's modulus of 1.02593 MPa and a tensile strength of 0.1345 MPa. In terms of biodegradation, the cornstarch-based bioplastic decomposes by approximately 80 % in soil after 28 days, aided by moisture and soil microorganisms. Water resistance analysis of the cornstarch-based bioplastic indicates that the sample containing 0.1 g of TiO2 exhibits the highest percentage, with 66.66 % absorption after 120 s. Nutrient concentration analysis using mung bean plants shows increased levels of calcium, potassium, and iron in samples with TiO2, particularly in Sample (II) containing 0.1 g of TiO2, which has significantly higher nutrient content, namely 2.15 % calcium, 1.99 % potassium, and 424.46 ppm iron.
