dc.descriptionThe objectives of the research was to evaluate physical properties, color, water vapor transmission rate and antimicrobial activity of sago-based biodegradable film made by adding of glycerol, carboxymethyl cellulose (CMC), potassium sorbate and coconut oil. The research was conducted on two steps which did continuosly. During the first step the research was held on various of concentration of glycerol (1, 1.5, 2.0 and 2.5%) and concentration of carboxymethil cellulose (CMC) (0.75; 1.0; 1.25 and 1.5 %). The formula which produced the best characteristic of biodegardable film was then used in the second step. In the second step of study, the antimicrobial material (coconut oil and potassium sorbate) were utilized in processing of sago-based biodegradable film. The concentration of potassium sorbate and coconut oil were (1.0, 1.5 and 2.0%) and (0, 0.3 dan 0.6%), respectively. The research results showed that, the biodegradable film obtained on 1.0% of glycerol and 1.0% of CMC having lowest elongation around 109.90%. It was then used for the second step for preparation of biodegradable film. Biodegradable film which were resulted by additon of coconut oil having plasticity better than the ones using potassium sorbate. Addition of pottasium sorbate effected the yelllow color of the biodegradable film. The biodegradable film prepared by utilized of potassium sorbate and oil were found not effectively to inhibit Eschericchia coli dan Staphylococcus aureus.ABSTRAKPenelitian ini bertujuan untuk mengetahui sifat fisik, warna dan laju transmisi uap air serta sifat antimikroba biodegradable film pati sagu dengan penambahan gliserol, carboxymethyl cellulose (CMC), kalium sorbat dan minyak kelapa. Penelitian ini terdiri atas dua tahap, pada tahap pertama gliserol dan CMC digunakan beberapa konsentrasi berturut-turut, yaitu (1%, 1,5%, 2,0% dan 2,5 %) dan (0,75%, 1,0%, 1,25% dan 1,5%). Kombinasi perlakuan terbaik tahap pertama digunakan untuk penelitian tahap kedua. Pada penelitian tahap kedua dilakukan penambahan bahan antimikroba kalium sorbat dan minyak kelapa pada beberapa konsentrasi, berturut-turut (1,0; 1,5 dan 2%) dan (0,3 dan 0,6%). Hasil penelitian menunjukkan bertambahnya konsentrasi gliserol menghasilkan biodegradable film dengan kuat tarik yang makin tinggi dan daya mulur makin turun. Pada konsentrasi gliserol yang tetap, nilai kuat tarik meningkat dan daya mulur menurun dengan bertambahnya konsentrasi CMC. Biodegradable film yang diproses menggunakan 1,0% gliserol dan 1,0% CMC memiliki daya mulur terendah hanya 109,90%. Kombinasi gliserol dan CMC ini selanjutnya digunakan untuk pembuatan biodegradable film yang ditambahkan minyak kelapa dan kalium sorbat. Biodegradable film yang diproses dengan penambahan minyak kelapa memiliki plastisitas yang lebih baik dibanding dengan penambahan kalium sorbat. Warna biodegradable film cenderung lebih kuning dibanding tanpa penambahan kalium sorbat. Biodegradable film yang dihasilkan dengan penambahan kalium sorbat dan minyak kelapa belum menunjukkan penghambatan terhadap Eschericchia coli dan Staphylococcus aureus. en-US
