modified tapioca - Opis:
- This research aimed to characterize bioplastic packaging made from modified tapioca flour so that it has the best thickness, transparency, tensile strength, elasticity and biodegradability values. This research was conducted at the Laboratory of Fisheries Products Processing, Faculty of Fisheries and Marine Sciences, Padjadjaran University, Jatinangor, starting from February-April 2019. Bioplastic were tested namely bioplastic in four treatments and three repeat with the addition of chitosan (K) and gelatin (G) concentrations, namely treatment A (2% K, 5% G), B (3% K, 10% G), C ( 4% K, 15% G), and D (4% K, 20% G). The data obtained were analyzed using a comparative descriptive method. The parameters observed included thickness, transparency, tensile strength, percent elongation, and biodegradability. Thickness testing with measurement methods at 5 different spots using a digital screw micrometer. Transparency testing was done by the method of inserting a sample in the spectrophotometer and the absorbance value was determined. Tensile strength and elongation tests were carried out by the withdrawal method at both ends of the sample using the Instron tool. Testing the value of biodegradability was carried out using the soil burial test method. The best bioplastic packaging produced is using the addition of 2% chitosan and 5% gelatin concentration which is seen from the thickness parameter values of 0,072 mm, transparency value of bioplastic 2,09, the tensile strength of 19,05 MPa, percent elongation 28,333% and can be degraded by soil after 14 days about 99,84% based on Japanesse Industrial Standard (JIS).
