Abstract
INDONESIA:
Edible film merupakan salah satu alternatif bahan pelindung yang ramah lingkungan untuk menangani kerusakan lingkungan akibat limbah sampah plastik yang terjadi di masyarakat. Plastik sintetis sulit terdegradasi di alam sehingga diperlukan bahan utama yang ramah lingkungan dan ekonomis berupa pati bonggol pisang. Ditambahkan jahe sebagai antioksidan, sehingga dihasilkan edible film yang memiliki umur simpan lebih lama. Selain itu, ditambah gliserol sebagai pemlastis untuk menghasilkan edible film yang lebih elastis. Penelitian ini bertujuan untuk mengetahui gugus fungsi, sifat fisis dan mekanis edible film. Variasi konsentrasi antara pati, antioksidan jahe dan gliserol yang digunakan yaitu 100:0:0; 95:0:5; 90:5:5; 85:5:10; 80:10:10; 75:10:15 (% b/v). Pada Konsentrasi gliserol 15% dihasilkan edible film dengan nilai swelling terbesar yaitu 96,9%. Nilai kuat tarik dan modulus young terbesar dihasilkan pada edible film yang tanpa ditambah gliserol dan antioksidan jahe. Sedangkan nilai elongasi terbesar dihasilkan pada konsentrasi pati bonggol pisang, antioksidan jahe dan gliserol 80:10:10 (% b/v) sebesar 8.7%. Pada uji FTIR terdapat gugus fungsi berupa O-H alkohol fenol, N-H dan C-H asam karboksilat dan ammonium, C≡C asetilen, C-O eter, sehingga bahan tersebut mudah terdegradasi dan memiliki umur simpan tahan lama.
ENGLISH:
Edible films is one of the alternative protective materials which are environmentally to handle the environmental damage caused by plastic waste that occured in the community. Synthetic plastic is degraded to the nature hardly, so it is a necessary to use an enviromentally and economical primary materials form such as banana’s tuber starch. Added a ginger as an antioxidant, so that the resulting edible film has a longer shelf life. Additionally, add a glycerol as a plasticizer to produce the edible film more elastic. This study aims to determine the functional groups, physical and mechanical properties of edible film. The concentration variations of starch, ginger antioxidants and glycerol used is 100: 0: 0; 95: 0: 5; 90: 5: 5; 85: 5: 10; 80:10:10; 75:10:15 (% w / v). At 15% glycerol’s concentration resulting an edible film with swelling value of the total of 96.9%. The values of tensile strength and Young's modulus produced the largest edible film without glycerol and ginger antioxidants. While the greatest elongation’s values are produced at a concentration of banana’s tuber starch, ginger antioxidants and glycerol 80:10:10 (% b / v) of 8.7%. In the FTIR test there are functional groups such as phenol alcohol O-H, N-H and C-H carboxylic acid and ammonium, C≡C acetylene, C-O ether, so the materials are degraded easily and has a long-lasting shelf life.
