PENGARUH PENAMBAHAN CELLULOSE NANOCRYSTAL (CNC) DARI KULIT DURIAN Durio Zibethinus Murr TERHADAP KARAKTERISTIK BIONANOCOMPOSITE EDIBLE FILM BERBASIS GELATIN

THE EFFECT OF ADDING CELLULOSE NANOCRYSTAL (CNC) FROM DURIAN SKIN DURIO ZIBETHINUS MURR TO  CHARACTERITRATION OF BIONANOCOMPOSITE GELATIN EDIBLE FILM

Penelitian ini bertujuan untuk yang pertama yaitu mengetahui sintesis Cellulose Nanocrystal (CNC), dari kulit durian (Durio Zibethinus Murr) menggunakan metode hidrolisis asam, dan ultra-sonikasi. Kedua mengetahui karakteristik dari pengaruh penambahan Cellulose Nanocrystal (CNC) dari hasil sintesis tersebut, dengan penambahan berturut-turut 0%, 1%,3%, 5% dan 7% pada bionanocomposite edible film berbasis gelatin dengan campuran gliserol 0,75%. Karakterisasi nanocomposite edible film meliputi uji kuat tarik¸uji elongasi, gugus fungsional ditentukan menggunakan spektrofotometer FTIR, uji SEM, dan biodigradabili-tas menggunakan metode soil burial test. Hasil pengujian bi-onanocomposite edible film dengan penambahan CNC secara ber-turut-turut menunjukan nilai kuat tarik sebesar 2,501; 1,982; 2,218; 2,219; 1,951 Mpa; elongasi sebesar 44,8%, 63,3%, 25,1%, 40,6%, 43.4%; biodegradabilitas menunjukan degradasi sebesar 67,30; 86,50; 89,37; 91,99; 94,78; 91,99%; uji FTIR menunjukan adanya gugus fungsi yang sama dengan gugus fungsi selulosa pada hasil sintesis nanoselulosa; pada uji partikel size analizer PSA di-peroleh nilai rata-rata ukuran partikel sebesar 310,5 d.nm; dan pada uji SEM dapat melihat morfologi permukaan pada matriks edible film setelah penamba- han CNC 5%.

This research has a goal is to find out the synthesis of Cellulose Nanocrystal (CNC), from the skin of durian (Durio Zibethinus Murr) using acid hydrolysis and ultrasonication methods. Knowing the characteristics of the effect the addition Cellulose Nanocrystal (CNC) from the synthesis results, with consecutive addition of 0%, 1%,3%, 5% and 7% on a gelatin-based bionanocomposite edible film with a mixture of 0.75% glycerol. Characterization of edible film nanocomposite includes tensile strength test,

¸elongation test, functional groups determined using FTIR spec- trophotometer, SEM test, and biodigradability using soil burial test method. The test results of bionanocomposite edible film with the addition of CNC successively show a tensile strength value of 2.501; 1,982; 2,218; 2,219; 1,951 MPa; elongation of 44.8%, 63.3%, 25.1%,

40.6%, 43.4%; biodegradability showed degradation of 67.30; 86.50;

89.37; 91.99; 94.78; 91.99%; the FTIR test showed the presence of the same functional group as the cellulose functional group in the synthesis of nanocellulose; in the PSA particle size analyzer test, the average particle size value was 310.5 d.nm; and in the SEM test use to know the morphology of the edible film matrix after the addition of 5% CNC.
