Abstract

Telah dilakukan penelitian tentang pengaruh penambahan serbuk gelatin terhadap sifat mekanik dan biodegradabilitas plastik campuran polietilen tereftalat bekas dan pati sagu. Pada penelitian ini dibuat sampel dengan 4 macam variasi penambahan serbuk gelatin yaitu 0 g, 5 g, 10 g dan 15 g. Sampel tersebut dikubur selama 10 hari, 20 hari, 30 hari dan 40 hari. Kemudian dilakukan pengujian sifat mekanik (kuat lentur dan kuat tarik) dan biodegradabilitas dari sampel. Hasil menunjukkan bahwa serbuk gelatin kurang mempengaruhi kekuatan lentur sampel, nilai kuat lentur tertinggi dimiliki sampel tanpa penambahan serbuk gelatin. Nilai kuat tarik tertinggi dimiliki sampel dengan penambahan serbuk gelatin sebanyak 5 g, yaitu sebesar 505,411 N/mm2. Sampel yang paling cepat terdegradasi adalah sampel dengan penambahan serbuk gelatin sebanyak 15 g.
