Abstract

Problems related to landfills of plastic packaging waste are a source of environmental pollution. This research provides innovation in utilizing biodegradable plastic from cassava and leri peel starch with the addition of chitosan. This study aimed to analyze the results of the synthesis and characterization of chitosan membranes with a combination of cassava and leri peel starch and determine the biodegradation time of biodegradable plastic in EM-4 bioactivation. This study characterized biodegradable plastic membranes using test parameters, namely the SEM, FTIR, Swelling, and tensile strength tests. The biodegradation test was carried out by immersing biodegradable plastic membranes in an EM-4 bioactator for 7 days. Based on the results obtained from the characterization of biodegradable plastic membranes, namely the swelling test with concentrations of 5:3, 7:3, and 9:3, with yield values ​​of 62.9921%, 69.8902%, and 71.4286%. The SEM test obtained the best results at a concentration of 7:3. FTIR test on biodegradable plastic membranes containing hydroxyl (O-H) and carbonyl (C-O) groups. The tensile test obtained optimum results at the concentration of biodegradable plastic membranes, namely 9:3. As for the biodegradation test that has been carried out, the start time for degradation is 3 days.

Abstract

Polimer alam dapat berasal dari hewan, mikroorganisme, dan tumbuhan sebagai makromolekul protein dari asam amino yang diikat oleh peptida. Polimer alam dapat dimanfaatkan sebagai bahan ramah lingkungan dalam menciptakan plastik yang mampu terurai dalam waktu singkat oleh mikroorganisme. Polimer alam seperti amilum, selulosa, karagenan, kitin, kitosan, alginat dan pektin dapat dimanfaatkan sebagai bahan dasar dalam pembuatan plastik ramah lingkungan atau yang umum disebut plastik biodegradable. Plastik biodegradable dapat dijadikan alternatif mengurangi penggunaan plastik sintetis yang tidak ramah lingkungan. Plastik biodegradable memiliki sifat mudah terurai sehingga dapat mengurangi tingkat pencemaran lingkungan. Beberapa penelitian telah dilakukan untuk memanfaatkan polimer alam dalam pembuatan plastik ramah lingkungan. Plastik ramah lingkungan yang disintesis dari polimer alam memiliki kualitas mendekati standar ketahanan air yang mengacu pada Standar Nasional Indonesia (SNI).
