ABSTRAKPlastik biodegradable adalah kemasan yang dapat diurai oleh mikroorganisme sehingga menjadi alternatif untuk menggantikan plastik kemasan konvensional yang menimbulkan permasalahan bagi lingkungan. Penelitian ini bertujuan untuk mengevaluasi pengaruh terhadap uji mekanisnya dan lain-lain yang terdiri atas tiga variabel dan masing-masing variabel terdiri dari tiga taraf kosentrasi. Variabel pertama adalah variasi penambahan grafting Poly(NIPAM)-kitosan yang terdiri dari kosentrasi 5%, 7% dan 9%. Variabel kedua adalah variasi penambahan gliserol yang terdiri dari kosentrasi 15%, 30%, 45% dan variabel ketiga adalah variasi penambahan minyak kayu manis yang terdiri dari kosentrasi 10%, 15% dan 20%. Penelitian ini menghasilkan plastik berupa lembaran tipis, transparan, dan elastis serta memiliki warna bening sedikit kekuningan. Plastik yang dihasilkan memiliki nilai kuat tarik sebesar 1,34-2,57 MPa, elongasi 36,22-66,30%, dan penyerapan air 22,22%-58,82%. Hasil uji antioksidan dilakukan dengan membungkus apel dengan plastik biodegradable yang mengandung minyak kayu manis mampu menghambat pertumbuhan mikroorganisme, apel mengalami perubahan signifikan pada hari ke 8. Pada uji biodegrabilitas plastik ini terurai dalam tanah selama 56 hari. ABSTRACTNonbiodegradable plastic is packaging that can be decomposed by microorganisms so that a viable alternative to replace conventional plastic packaging that cause problems for the environment. This study was aimed to evaluate the effect of the mechanical test and others consisting of three variables and each variable consists of three level of concentration. The first variable was additional grafting of Poly (Nipam) -chytosan consisting of 5%, 7% and 9%. The second variable was additional glycerols which were 15%, 30%, 45%. The third variable was concentrations of cinnamon oil which were 10%, 15% and 20%. This research produced a thin sheet of plastic, transparant, and elastic and it had a slightly yellowish translucent color. The tensile strength value was about 1. .82% of water absorption. Antioxidant test was performed by wrapping an apple with biodegradable plastics containing cinnamon oil. It could inhibit the growth of microorganisms. The apples changed significantly on day 8. In biodegradability test, this plastic was decomposed after buried for 56 days in the soil.
