Abstract

Penelitian ini dilakukan untuk menentukan pengaruh gula jagung terhadap sifat mekanik dan biodegradabilitas plastik campuran polypropylene bekas dan pati sagu. Pada penelitian ini dibuat 5 sampel dengan variasi massa gula jagung yang berbeda. Pengukuran dilakukan terhadap kuat tekan dan kuat lentur dari setiap sampel. Penentuntuan tingkat degradabilitas ditentukan dengan mengubur sampel selama tujuh hari. Hasil menunjukkan bahwa kuat lentur dan kuat tekan plastik mengalami kenaikan dengan penambahan gula jagung. Nilai kuat tekan dan kuat lentur maksimum terdapat pada komposisi 90 gr : 10 gr : 10 gr yaitu 87,04 kg/cm2 dan 96,9 kg/cm2 . Ditinjau dari segi fisis setelah proses penguburan, plastik campuran dengan komposisi gula jagung terbanyak memiliki permukaan paling kasar dan paling banyak lobang. Hal ini dapat diartikan bahwa plastik dengan komposisi gula jagung terbanyak memiliki tingkat degradabilitas tertinggi.
