| Abstract | ||
| Traditional plastic materials have become one of the materials that represent severe harm to the environment because they are non-biodegradable materials, as they are considered derivatives of organic materials that are very stable and large in molecular size. Starch is a natural polymer consisting of many units of glucose in the form of a large polymer. In this project work, potatoes were chosen as plant tubers in the preparation of biodegradable plastic films. Starch powders were prepared from potatoes by washing, cutting, grinding, drying and crushing. Then the biodegradable plastic film was prepared using starch powder, water, acetic acid and glycerin as plasticizers. In this project, starch extraction from selected tubers with high starch content namely potato was used as raw material for bioplastic. The chemical, Sensory, water uptake and biodegradable properties of the products were analyzed using FTIR spectroscopy. Where the infrared spectra revealed the presence of absorption values for the groups hydroxyl, carbon-hydrogen, carbonyl and carbonoxygen, this confirms that the biodegradable biopolymer and bioplastic may have actually been synthesized. The good ability to biodegrade the plastic was confirmed using a soil burial test, which was observed by calculating the soil decomposition rate of potato-based bioplastic in a period of 10 days, which amounted to 24%. Through previous experiments, it became clear that these synthetic plastic materials from natural sources have good sensory and chemical properties and also have a good degree of biodegradability. This makes these synthetic plastic materials considered a good alternative to plastic materials derived from organic sources that lead to pollution of the traditional environment. | ||
