Abstract

Plastik berbasis minyak bumi sulit terdegradasi sehingga diperlukan kemasan alternatif dari bahan terbarukan. Penelitian ini bertujuan menganalisis pengaruh komposisi biopolimer polisakarida dan konsentrasi cellulose nanocrystal (CNC) terhadap karakteristik, ketahanan air, dan sifat barrier uap air film pati–κ-karagenan–alginat. Film dibuat dengan metode solution casting menggunakan campuran pati tapioka dan kentang 30:70, gliserol, Tween 80, beeswax, dan asam stearat. Penelitian terdiri atas variasi κ-karagenan, alginat, dan CNC 1–5%. Cr0.2 dipilih pada tahap pertama karena memiliki WVTR 5,09 × 10⁻³ g m⁻² s⁻¹, WVP 1,76 × 10⁻¹⁰ g m⁻¹ Pa⁻¹ s⁻¹, kelarutan air panas sekitar 92%, water contact angle sekitar 45°, dan opasitas 0,9057. Pada tahap kedua, CrAl0.5 dipilih berdasarkan densitas 1,696 g cm⁻³, water activity 0,600, water contact angle 69,97°, dan elongation at break 36,66%. Film dengan CNC memiliki WVTR 5,43–6,84 × 10⁻³ g m⁻² s⁻¹ dan WVP 1,72–2,00 × 10⁻¹⁰ g m⁻¹ Pa⁻¹ s⁻¹. CrAl-C5% dipilih karena memiliki water activity 0,580, kelarutan suhu ruang 38,93%, kelarutan air panas 42,04%, dan WVTR terendah 5,43 × 10⁻³ g m⁻² s⁻¹, sedangkan WVP terendah diperoleh pada CrAl-C3% sebesar 1,72 × 10⁻¹⁰ g m⁻¹ Pa⁻¹ s⁻¹. Film mengalami penurunan massa selama 12 hari penguburan dan dapat dibentuk menjadi sachet pangan kering. Secara keseluruhan, variasi κ-karagenan, alginat, dan CNC memberikan pengaruh nonlinier, dengan CrAl-C5% menunjukkan kombinasi sifat terbaik.

Petroleum-based plastics are difficult to degrade, creating a need for renewable packaging materials. This study evaluated the effects of polysaccharide composition and cellulose nanocrystal (CNC) concentration on the characteristics, water resistance, and water vapor barrier properties of starch–κ-carrageenan–alginate films. Films were prepared by solution casting using tapioca and potato starch at a 30:70 ratio, glycerol, Tween 80, beeswax, and stearic acid. The study examined variations in κ-carrageenan, alginate, and CNC concentrations of 1–5%. Cr0.2 was selected in the first stage, with a WVTR of 5.09 × 10⁻³ g m⁻² s⁻¹ and WVP of 1.76 × 10⁻¹⁰ g m⁻¹ Pa⁻¹ s⁻¹. CrAl0.5 was selected in the second stage based on its density of 1.696 g cm⁻³, water contact angle of 69.97°, and elongation at break of 36.66%. CNC-containing films showed WVTR values of 5.43–6.84 × 10⁻³ g m⁻² s⁻¹ and WVP values of 1.72–2.00 × 10⁻¹⁰ g m⁻¹ Pa⁻¹ s⁻¹. CrAl-C5% was selected because it had the lowest WVTR, low water activity, and reduced solubility, while CrAl-C3% exhibited the lowest WVP. The films degraded during 12 days of soil burial and could be formed into dry-food sachets. Overall, κ-carrageenan, alginate, and CNC affected film properties nonlinearly, with CrAl-C5% showing the best overall performance.
