Abstract

AbstractGembili (Dioscorea esculenta) is a tuber-producing plant containing 14.63% inulin, a Water-Soluble Polysaccharide (WSP). This study aims to determine the optimum point of the material to solvent ratio and Microwave-Assisted Extraction (MAE) time needed to extract gembili WSP, and determine the WSP's characteristics produced. The optimization process uses the Response Surface Methodology-Central Composite Design (RSM-CCD) with Design Expert 7.0 software. The material to solvent ratio's minimum and maximum points are 1:25 g/L and 1:45 g/L, while the minimum and maximum points of extraction time are 20 minutes and 40 minutes. This study observed 13 experimental combinations and responses from gembili WSP yield, WSP powder inulin levels, and WSP solubility. The results showed that the optimum conditions of material to solvent were at a 1:33.81 g/mL ratio, and the extraction time was 29.26 minutes. This optimum condition resulted in 32.42% WSP yield, 40.8% inulin content in WSP powder, 26.98% WSP solubility, 12.24% WSP water content, and 49.3 cp WSP viscosity. These results indicate that extraction using a microwave can increase WSP's rich inulin yield from gembili tubers.Keywords: gembili, inulin, microwave, optimization, Water-Soluble Polysaccharides AbstrakGembili (Dioscorea esculenta) merupakan tanaman penghasil umbi yang mengandung 14,63% inulin, yang merupakan Polisakarida Larut Air (PLA). Tujuan penelitian ini untuk mengetahui titik optimum rasio bahan terhadap pelarut dan lama waktu ekstraksi PLA ubi gembili yang dibutuhkan menggunakan Microwave-Assisted Extraction (MAE) serta untuk mengetahui karakteristik PLA umbi gembili yang dihasilkan. Proses optimasi menggunakan Respon Surface Methodology-Central Composit Design (RSM-CCD) dengan bantuan software Design Expert 7.0. Titik minimum dan maksimum rasio bahan:pelarut adalah 1:25 g/L dan 1:45 g/L, sedangkan titik minimum dan maksimum lama waktu ekstraksi adalah 20 menit dan 40 menit. Penelitian ini mengamati 13 kombinasi percobaan dan respon, yaitu rendemen PLA, kadar inulin pada bubuk PLA, dan kelarutan PLA. Hasil penelitian menunjukkan bahwa kondisi optimum bahan:pelarut terdapat pada rasio 1:33,81 g/mL dan lama waktu ekstraksi adalah 29,26 menit. Kondisi optimum ini menghasilkan 32,42% rendemen PLA, 40,8% kadar inulin pada bubuk PLA, 26,98% kelarutan PLA, 12,24% kadar air PLA, dan 49.3 cp viskositas PLA. Hasil tersebut menunjukkan bahwa ekstraksi menggunakan microwave berpotensi meningkatkan rendemen PLA kaya inulin dari umbi gembili.Kata kunci: gembili, inulin, microwave, optimasi, Polisakarida Larut Air

Abstract

AbstractThis research aimed to obtain the best formulation of corn starch, carrageenan, and rice bran as the main components of edible film to improve formula’s viscosity, water content, and Water Vapour Transmission Rate (WVTR). This research was an experimental research using Randomized Complete Block Design (RCBD). The first factor was corn starch concentration (1.5%; 2.5%; 3.5%), the second factor was carrageenan concentration (0.67%; 1%; 1.33%), and the third factor was rice bran concentration (0.12%; 0.25%; 0.38%). The analysis of variance showed that the interaction of corn starch, carrageenan, and rice bran has a significant impact on the viscosity, water content, and WVTR value of the edible film. Based on the viscosity, water content, and WVTR value of the edible film, the best formulation was found in the edible film with the corn starch concentration of 2.5%, 1% carrageenan, and 0.25% rice bran. The formula's viscosity value of this edible film was 165.1 ± 5.3 cP, with 14.65 ± 0.05% of water content, and 60.13 ± 0.05 g/m2/h of WVTR value.Keywords: carrageenan, corn starch, edible film, rice bran Abstrak Tujuan dari penelitian ini adalah untuk mendapatkan formulasi terbaik dari pati maizena, karagenan, dan bekatul padi sebagai komponen dasar edible film untuk meningkatkan viskositas formula. kadar air, dan Water Vapour Transmission Rate (WVTR). Penelitian ini dilakukan secara eksperimental dengan menggunakan Rancangan Acak Kelompok (RAK). Faktor pertama adalah konsentrasi pati maizena (1,5% ; 2,5% ; 3,5%), faktor kedua adalah konsentrasi karagenan (0,67%; 1%; 1,33%), dan faktor ketiga adalah konsentrasi bekatul padi (0,12% ; 0,25% ; 0,38%). Hasil analisis ragam menunjukkan interaksi penambahan pati maizena, karagenan, dan bekatul padi berpengaruh nyata terhadap viskositas formula edible film, kadar air, dan nilai WVTR edible film. Formulasi terbaik sesuai karakteristik viskositas formula edible film, kadar air, dan nilai WVTR edible film adalah edible film dengan konsentrasi pati maizena 2,5%, karagenan 1%, dan bekatul 0,25% yang memiliki nilai viskositas formula edible film sebesar 165,1 ± 5,3 cP, kadar air edible film sebesar 14,65 ± 0,05%, dan nilai WVTR edible film sebesar 60,13 ± 0,05 g/m2/jam.Kata kunci: bekatul padi, edible film, karagenan, pati maizena
