39PendahuluanLatar BelakangPisang merupakan tanaman hortlikurtura yang dapat tumbuh dengan baik di Indonesia karena iklim dan tanah yang sesuai untuk pertumbuhannya. Pisang adalah salah satu buah yang mengandung zat gizi yang baik. Produksi pisang pada tahun 2003 jumlah produksi pisang di Indonesia mencapai 4.177.155 ton hingga pada tahun 2009 produksi pisang terus meningkat menjadi 6.373.533 ton (BPS, 2011). Salah satu produk olahan pisang adalah keripik pisang. Produk samping industri keripik pisang adalah limbah kulit pisang. Menurut FAO (2003) limbah kulit pisang berjumlah 40% dari total jumlah berat buah pisang. Limbah kulit pisang selama ini hanya dibuat sebagai pakan ternak, padahal mengandung komponen berupa pektin. Pektin banyak terdapat pada bahan limbah hasil pertanian seperti kulit buah. Potensi limbah kulit Technical PaperKarakteristik Edible Film dari Pektin Hasil Ekstraksi Kulit PisangCharacterization Of Edible Film Based On Pectin Extracted From Banana Peel Muhammad Sudirman Akili1, Usman Ahmad2dan Nugraha Edhi Suyatma3AbstractBanana peel is a waste of banana processing industries which is obviously uneconomy and unfriendly to the environment. However, this material could be used as a source of important natural compounds, such as pectin. Owing to the fact that pectin has good gelling properties, it can be used to make edible film. The objectives of this research were to extract and characterize pectin from banana peel and to make edible film from the obtained pectin by using glycerol as plasticizer. Characterization of edible films were conducted in terms of color, thickness, elongation, tensile strength and water vapor transmission. The research used factorial completely randomized design. The results showed that yield of pectin made from ambon banana peel ripeness level one was 8.42% with the characteristics werewater content: 11.27% (<12%), ash content: 1.70%, low methoxil content: 4.15% (<7%) and galacturonat content: 25.86% (65%). The addition of glycerol significantly increased elongation and decreased tensile strength of edible film. Based on edible film result, the recomended treatment is the addition with glycerol 20% as plasticizer of pectin based edible film.Keywords : banana peel,pectin,edible film.AbstrakKulit pisang adalah limbah hasil industri pengolahan yang tidak bernilai ekonomi dan ramah lingkungan. Meskipun limbah kulit pisang dapat digunakan sebagai sumber pektin yang merupakan senyawa alami. Kenyataannya bahwa pektin memiliki sifat gel yang baik sehingga dapat digunakan untuk membuat kemasan yang dapat dimakan (edible film. Tujuan dari penelitian ini adalah mengekstrak dan mengkarakterisasi pektin dari kulit pisang untuk membuat edibe film dengan penambahan gliserol untuk memberikan sifat plastis dan elastis. Karakteristik edible film pada penelitian ini adalah warna, ketebalan, elongasi, kuat tarik dan laju transmisi uap air. Penelitian ini menggunakan rancangan acak lengkap. Hasil penelitian ini menunjukkan bahwa rendeman tertinggi terdapat pada pektin dari kulit pisang tingkat kematangan 1 dengan karakteristik kadar air: 11.27% (<12%), kadar abu: 1.70%, kandungan metoksil rendah: 4.15% (<7%)

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
