Abstract
The amount of plastic waste from food packaging was increasing and causing the disturbances in environmental and human health. The renewable food packaging innovations needed that can decompose quickly but still maintain the shelf life of food products, such as biogeradable film. This research used the basic ingredients of beneng taro starch, glycerol, and cellulose extracted from red seaweed Gracilaria sp. which is treated with different bleaching conditions during extraction. The purpose of this research was to determine the best cellulose bleaching conditions and the effect of different cellulose concentrations on the characteristics of biodegradable films. The method was used experimental with a Completely Randomized Design (CRD) which is divided into two stages of research, namely cellulose extraction with different bleaching conditions and making biogeradable films with different cellulose concentrations. The results of this research indicate that there is an effect of treatment on the research response. The best cellulose was obtained from the treatment using 4% NaOCl at room temperature for 6 hours during the bleaching process. The use of cellulose can increase the thickness, tensile strength, reduce the percentage of elongation and brightness of the film, increase the density value and water vapor transmission rate, and accelerate the degradation of the film.

| Additional Information: | Jumlah sampah plastik dari kemasan makanan semakin meningkat dan menyebabkan gangguan pada kesehatan lingkungan dan manusia. Oleh karena itu, diperlukan inovasi kemasan pangan terbarukan yang dapat terurai dengan cepat namun tetap mempertahankan masa simpan produk pangan, seperti biogeradable film. Penelitian ini menggunakan bahan dasar pati talas beneng, gliserol, dan selulosa yang diekstrak dari rumput laut merah Gracilaria sp. yang diberi perlakuan kondisi pemutihan yang berbeda saat ekstraksi. Tujuan dari penelitian ini adalah untuk mengetahui kondisi pemutihan selulosa yang terbaik dan pengaruh konsentrasi selulosa yang berbeda terhadap karakteristik film biodegradable. Metode yang digunakan adalah eksperimental dengan Rancangan Acak Lengkap (RAL) yang dibagi menjadi dua tahap penelitian, yaitu ekstraksi selulosa dengan kondisi pemutihan yang berbeda dan pembuatan film biodegradable dengan konsentrasi selulosa yang berbeda. Hasil dari penelitian ini menunjukkan bahwa terdapat pengaruh perlakuan terhadap respon penelitian. Selulosa terbaik diperoleh dari perlakuan dengan menggunakan NaOCl 4% pada suhu ruang selama 6 jam selama proses bleaching. Penggunaan selulosa dapat meningkatkan ketebalan, kekuatan tarik, menurunkan persentase pemanjangan dan kecerahan film, meningkatkan nilai densitas dan laju transmisi uap air, serta mempercepat degradasi film. | ||||||||||||
