Abstrak- Pektin adalah komponen polisakarida kompleks yang terdapat pada dinding sel tanaman. Pektin sering dimanfaatkan pada industri proses pengolahan makanan, koagulan pada industri karet dan adsorben pada pengolahan air limbah. Kulit pisang merupakan salah satu sumber pektin yang sangat potensial karena dalam kulit pisang terkandung senyawa pektin. Proses ekstraksi asam digunakan untuk dekomposisi komponen pektin yang terkandung dalam kulit pisang. Penelitian ini menggunakan 50 gram kulit pisang yang direaksikan dengan HCl dalam sebuah reaktor tangki berpengaduk. Proses ekstraksi ini dilakukan pada suhu 800C selama 1,5 jam dengan memvariasikan konsentrasi pelarut HCl (0,25N; 0,3N dan 0,35N. Tujuan penelitian ini adalah untuk mempelajari pengaruh konsentrasi pelarut HCl pada proses ekstraksi pektin. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi pelarut HCl maka semakin tinggi yield pektin yang dihasilkan. Yield pektin maksimum yang diperoleh pada penelitian ini adalah 67,55%. Kadar metoksil dan galakturonat yang diperoleh pada penelitian ini adalah 4,34% dan 84,48%.

Food packaging most used in order to keep the quality of food could be maintained to consumers. Plastic non-biogradable have weakness such as it is not degradable of environment and it is not safe to health because contain bhispenol. Edible film is solution for this problem because made of chitosan-starch. Starch is natural polymer that safe to use because easy to degradable, edible and economist. Corn starch contain high amylose content is 25%. Addition of chitosan could increase mechanical properties and barrier properties of edible film. The purpose of this research was to find out the effect of addition of chitosan on physiochemical properties edible film. Variation of chitosan used was 0,5; 1; 1,5 and 2 gram. The best result of solubility in water was addition chitosan 2 gram with value 49,74%.
