Abstract

This study investigated the effects of cassava starch-to-sugarcane bagasse cellulose ratio and polyvinyl alcohol (PVA) concentration on biodegradable foam properties. Samples were produced by thermopressing at 180°C for 1 minute using starch-to-cellulose ratios of 1:1–5:1 (w/w) and PVA concentrations of 5% and 10%. We evaluated water absorption, tensile strength, and biodegradation. Formulation significantly affected foam characteristics. Water absorption ranged from 7.40% to 21.05%, with the lowest value obtained at a 1:1 ratio and 10% PVA. The highest tensile strength (2.084 MPa) occurred at a 2:1 ratio and 5% PVA. The highest measured biodegradation was 41.49%, while complete degradation occurred within 34 days. These findings demonstrate the potential of cassava starch and sugarcane bagasse cellulose combined with PVA for developing biodegradable packaging foam.

Abstract

Industri tekstil di Indonesia memiliki peran penting dalam perekonomian nasional, namun tetap bergantung pada bahan baku sintetis berbasis impor yang berdampak negatif terhadap lingkungan. Untuk mengatasi permasalahan tersebut, diperlukan alternatif bahan baku yang ramah lingkungan dan tersedia secara lokal. Pelepah nipah ( Nypa Fruticans ), yang merupakan limbah pertanian di daerah pesisir Indonesia, mengandung senyawa lignoselulosa seperti selulosa, hemiselulosa, dan lignin, sehingga berpotensi diolah menjadi serat tekstil alami. Proses ekstraksi serat dilakukan menggunakan alat dekortikator, dilanjutkan dengan perendaman dalam larutan NaOH konsentrasi 4%, 5%, dan 6% selama 60 hingga 300 menit, serta tahap bleaching menggunakan NaClO. Analisis komponen kimia meliputi kadar selulosa, hemiselulosa, dan lignin menggunakan metode Chesson-Datta . Hasil terbaik diperoleh pada perlakuan dengan larutan NaOH 6% dengan waktu perendaman 300 menit, yang menghasilkan kandungan selulosa sebesar 49,73%, hemiselulosa 17,84%, dan lignin 8,71%. Nilai kekuatan tarik mencapai 171,03 MPa. Penurunan signifikan kadar lignin dan hemiselulosa menunjukkan keberhasilan proses delignifikasi, sementara peningkatan kadar selulosa berkontribusi terhadap kekuatan tarik serat. Hasil ini menunjukkan bahwa serat pelepah nipah berpotensi digunakan sebagai bahan baku tekstil ramah lingkungan.
