ABSTRAKPengemasan merupakan proses perlindungan suatu produk pangan yang bertujuan menjaga keawetan dan konsistensi mutu. Bahan pengemas dari plastik banyak digunakan dengan pertimbangan ekonomis, namun penggunaan material sintesis tersebut berdampak pada pencemaran lingkungan. Salah satu alternatif untuk menangani permasalahan tersebut dengan menggunakan material ramah lingkungan (biodegradable) seperti edible film. Penelitian ini bertujuan untuk mengkaji pengaruh temperatur pengeringan terhadap swelling dan tensile strength edible film hasil pemanfaatan pati limbah kulit singkong dengan penambahan ekstrak jahe merah. Penelitian ini diawali dengan tahap pembuatan ekstrak jahe merah dan pati dari limbah kulit singkong, setelah itu dilanjutkan dengan pembuatan edible film dengan variasi penambahan ekstrak jahe merah (0.5-1.1% w/v) dan diberi plasticizer berupa gliserol (1% v/v). Selanjutnya dilakukan tahapan pembuatan dan pencetakkan edible film dan pengeringan pada temperatur ( 50;60;700C). Hasil yang diperoleh selanjutnya dilakukan analisa swelling dan tensile strength. Hasil menunjukkan nilai swelling dan tensile strength tertinggi diperoleh pada pada penambahan ekstrak jahe merah 1.1% dan temperatur pengeringan 700C yaitu masing-masing 88.89 % dan 50,66 kg/cm2.Kata Kunci : Kemuluran, Kuat tarik, Lapisan edibel ABSTRACTPackaging is a protection food product to maintain the quality and durability of food. Plastic packaging is widely used for economic consideration, but it leads to environmental pollution. The alternative way to handle this problem is by using biodegradable material such as edible film. This study aims to examine the effect of dying temperature on the swelling and tensile strength of edible cassava peel starch film with the addition of red ginger extract. This research was started with the extraction of red ginger and cassava peel starch, followed by edible film making with variation of red ginger extract addition (0.5-1.1% w/v) and glycerol (1% v/v) as plasticizer. The next stages were production and molding of the edible film. The edible films were then dried at the temperature of (50;60;700C). Furthermore swelling and tensile strength analysis was conducted to the product of edible film. The results showed that the highest swelling and tensile strength values were obtained on the addition of red ginger extract of 1.1% and the drying temperature of 700C which were 88.89% and 50,664 kg / cm2 respectively.Keywords : Edible film, Swelling, Tensile strengthDownloads
