Abstract
Bioplastics are plastics made from natural materials such as starch, for example seeds and tubers, as well as from cellulose such as nata. Bioplastics have the property of being easily degraded which is broken down by microorganisms or weather. Pineapple peel is a part of the pineapple fruit that has been underutilized so that it ends up as waste. The high carbohydrate content in pineapple fruit peels has the potential to be used as raw material for nata production. as raw material for making nata. In addition, nata can also be made from rice washing water. Rice washing water has a lot of carbohydrate content, so it can be utilized by microorganisms as a medium for making nata. by microorganisms as a medium for making nata. The resulting nata can be utilized for bioplastic materials because of the high cellulose content in nata. which is quite high. This study aims to make bioplastics from pineapple peel nata and rice washing water. pineapple peel and rice washing water that meets the quality standards of bioplastics, as well as finding the best addition of CMC and glycerol.the best addition of CMC and glycerol in the bioplastic manufacturing process. Method The method of making bioplastics is by solution casting. The use of variables, namely nata 15 g, chitosan 3.5 g with 500 rpm stirring for 10 minutes at 70 ℃. Glycerol concentration variation 2%; 2.5%; 3%; 3.5%; 4% and CMC variation 4%; 6%; 8%; 10%; 12%. Based on the results of the study, the best condition for bioplastics is the addition of 8% CMC concentration with 3.5% glycerol variation. CMC concentration of 8% with 3.5% glycerol variation. The tensile strength value was 0.51 MPa, elongation of 71.49%, water resistance of 55.6517%, and biodegradation of 35,8188%. The results of the bioplastic SEM test obtained a very tight and fairly flat bioplastic structure. flat. In addition, the FTIR test found that bioplastics have 5 peaks where the 5 peaks represent the forming functional groups of bioplastics. These 5 peaks represent the forming functional groups of bioplastics such as the O-H functional group.
