Rohmawati, Triza Nofiya (2019) Pengaruh Variasi Plasticizer Sorbitol Dan Selulosa Asetat Tkks (Tandan Kosong Kelapa Sawit) Terhadap Biodegradabilitas Bioplastik Berbasis Pati Umbi Ganyong (Canna Edulis). Sarjana thesis, Universitas Brawijaya.
Abstract
Pada era modern saat ini banyak terjadi pencemaran lingkungan, salah satunya sampah plastik. Sehingga dibutuhkan usaha untuk mengurangi masalah tersebut dengan membuat bioplastik yang terbuat dari berbagai macam senyawa, diantaranya pati dan selulosa. Umbi ganyong (Canna edulis) adalah salah satu tanaman yang mengandung pati cukup tinggi. Namun bioplastik yang hanya terbuat dari pati memiliki sifat mekanik yang kurang baik, sehingga perlu ditambahkan penguat seperti selulosa asetat Tandan Kosong Kelapa Sawit (TKKS) dan plasticizer sorbitol. Tujuan penelitian ini adalah untuk mengetahui daya serap air, kelarutan, dan biodegradasi bioplastik dari pati umbi ganyong dengan penambahan selulosa asetat TKKS dan sorbitol menggunakan metode solution casting. Pada penelitian ini digunakan Rancangan Acak Kelompok (RAK) faktorial dengan konsentrasi selulosa asetat dari TKKS sebanyak, 1 gr, 1.5 gr, 2 gr, 2.5 gr, dan 3 gr serta konsentrasi sorbitol sebanyak 1 ml, 2 ml, 3 ml, 4 ml, dan 5 ml. Nilai daya serap air yang terbaik pada penelitian ini pada penambahan selulosa asetat 3 gr dan sorbitol 2 ml sebesar 12.311%. nilai kelarutan dan biodegradabilitas yang terbaik dalam penelitian ini diperoleh dengan penambahan selulosa asetat 1 gr, namun dengan penambahan sorbitol yang berbeda yaitu 4 ml dan 3 ml. Nilai kelarutan dan biodegradabilitas yang terbaik masing-masing adalah 48.803% dan 96.203%
English Abstract
In the modern era, there is a lot of environmental pollution, one of which is plastic waste. Therefore, efforts are needed to reduce the problem by making bioplastics made of various compounds, including starch and cellulose. Canna tubers (Canna edulis) is one of the plants that contains quite high starch. However, bioplastics which are only made from canna tuber starch have poor mechanical properties, so it needs to be added reinforcement such as cellulose acetate Empty Palm Fruit Bunch (EPFB) and sorbitol plasticizer. The purpose of this study was to determine the water absorption, solubility, and biodegradation of bioplastics from canna starch by adding cellulose acetate EPFB and sorbitol using the solution casting method. This research used factorial randomized block design with cellulose acetate concentrations from EPFB for 1 gram, 1.5 gr, 2 gr, 2.5 gr, and 3 gr and sorbitol concentrations of 1 ml, 2 ml, 3 ml, 4 ml, and 5 ml. The best absorption value of bioplastic in this study was obtained by adding 3 gr cellulose acetate and 2 ml sorbitol that is equal to 12.311%. The best solubility and biodegradability values of bioplastics in this study were obtained by adding 1 gr cellulose acetate, but with the addition of different sorbitol which were 4 ml and 3 ml. The best solubility and biodegradability values were 48,803% and 96,203%, respectively.
