Abstract

ABSTRAK KARAKTERISASI BIOPLASTIK DARI K-KARAGENAN EUCHEUMACOTTONII TERPLASTISASI BERPENGUAT NANOSELULOSA. Nanoselulosa dapat digunakan sebagai penguat bioplastik karena memiliki kelebihan yaitu dapat meningkatkan kekuatan, kekakuan, ketangguhan, dan perbaikkan sifat permeabilitas. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan nanoselulosa terhadap karakteristik bioplastik karagenan Eucheuma Cottonii terplastisasi dan memperbaiki sifat dari bioplastik yang belum bisa diaplikasikan. Penambahan nanoselulosa dilakukan pada konsentrasi 0,5%: 1%: 2,5%: 5%, 7,5% dan 10%, dengan mencampurnya pada K-Karagenan Eucheuma Cottonii 3% dan komposisi gliserol 35%. Hasil analisis sidik ragam (ANOVA) menunjukkan bahwa pemberian perlakuan nanoselulosa pada berbagai konsentrasi tidak memiliki pengaruh terhadap karakteristik sifat bioplastik seperti ketebalan (Nanoselulosa 10% ; 0,155 mm), water solubility (Nanoselulosa 1% ; 61,285%), dan water vapor transmission rate (WVTR) (Nanoselulosa 10% ; 36.397,729 g/m 2 /day). Namun, berpengaruh nyata terhadap karakteristik sifat bioplastik seperti kadar air (Nanoselulosa 0,5% ; 19,656%), kuat tarik (Nanoselulosa 2,5% ; 93,120 KgF/cm 2 atau 9,132 Mpa), %-perpanjangan (Nanoselulosa 7,5% ; 64,625%), modulus young (Nanoselulosa 0,5% ; 37,222 Mpa atau 0,037222 Gpa), dan biodegradasi (Nanoselulosa 0,5% ; 8% selama 25 hari). Hasil karakteristik tersebut telah sesuai dengan Japanese International Standards (JIS 2-1707) dan referensi yang ada, kecuali water solubility dan water vapor transmission rate (WVTR). ABSTRACT CHARACTERISTICS OF K-CARAGEENAN EUCHEUMA COTTONII BIOPLASTIC REINFORCED WITH NANOCELLULOSE. Nanocellulose can be used as bioplastic reinforcement because it has the advantage that it can increase strength, stiffness, toughness, and improve permeability. This study aims to determine the effect of the addition of nanocellulose on the characteristics of plasticized Eucheuma Cottonii carrageenan and to improve the properties of bioplastics that cannot be applied. The addition of nanocellulose was carried out at a concentration of 0.5%: 1%: 2.5%: 5%, 7.5% and 10%, by mixing it in K-Carrageenan Eucheuma Cottonii 3% and glycerol composition of 35%. The results of analysis of variance (ANOVA) showed that giving nanocellulose treatment at various concentrations had no effect on the characteristics of bioplastic properties such as thickness (10% Nanocellulose; 0.155 mm), water solubility (1% Nanocellulose; 61.285%), and water vapor transmission rate (WVTR) (Nanocellulose 10%; 36,397,729 g / m 2 / day). However, a significant effect on the characteristics of bioplastic properties such as moisture content (Nanocellulose 0.5%; 19.656%), tensile strength (Nanocellulose 2.5%; 93.120 KgF / cm 2 or 9.132 Mpa),%-length (7.5% Nanocellulose; 64.625%), modulus young (Nanocellulose 0.5%; 37.222 Mpa or 0.037222 Gpa), and biodegradation (Nanocellulose 0.5%; 8% for 25 days). The results of these characteristics are in accordance with existing international and national standards, except for water solubility and water vapor transmission rate (WVTR).
