Nugraha, Muhammad Arsya and Hendrix Yulis Setyawan,, STP, M.Si, PhD and Arie Febrianto Mulyadi,, STP, MP (2022) Optimasi Konsentrasi CMC dan Gliserol pada Formulasi Edible Film Berbahan Dasar SCOBY Menggunakan Metode Simplex Lattice Design (SLD). Sarjana thesis, Universitas Brawijaya.
Abstract
Edible Film merupakan salah satu inovasi bahan pengemas yang lebih ramah lingkungan dan biodegradable. Edible film dapat diperoleh melalui biopolimer. Salah satu biopolimer potensial beberapa tahun terakhir adalah SCOBY yang diketahui efisien dari segi ketersediaan, biaya, dan kandungan yang dimiliki. Walaupun demikian, terdapat beberapa faktor yang mampu memengaruhi karakteristik edible film yang dihasilkan, salah satunya adalah konsentrasi CMC dan gliserol. CMC diketahui mampu meningkatkan kuat tarik film, namun mampu menurunkan elongasi film. Sebaliknya, gliserol mampu meningkatkan elongasi film, namun mampu menurunkan kuat tarik film. Penelitian ini bertujuan untuk mengetahui konsentrasi CMC dan gliserol yang optimal pada formulasi edible film dengan karakteristik mekanik yang optimal. Penelitian dilakukan menggunakan metode Simplex Lattice Design (SLD) dengan dua faktor dan tiga respon. Faktor pertama adalah konsentrasi CMC dengan batas bawah (0 level) 1% dan batas atas (1 level) 2%. Faktor kedua adalah konsentrasi gliserol dengan batas bawah (0 level) 1,5% dan batas atas (1 level) 3%. Respon yang diuji meliputi kuat tarik, elongasi, dan ketebalan. Data dianalisis ragam ANOVA, kemudian dipilih perlakuan paling optimal dan dilakukan uji validasi. Solusi optimal pada program Design Expert terdapat pada konsentrasi CMC 2% dan gliserol 1,5%. Hasil rata rata pada pengujian solusi optimal yang diperoleh pada setiap respon meliputi 3,23 N untuk kuat tarik, 16,67% elongasi, serta ketebalan 0,08 mm. Berdasarkan hasil validasi, konsentrasi CMC dan gliserol memiliki pengaruh signifikan terhadap respon kuat tarik dan elongasi edible film berbahan dasar SCOBY.
English Abstract
Edible Films is one of the environmentally friendly and biodegradable packaging material. Edible films can be obtained through biopolymers. One of the potential biopolymers in recent years is SCOBY which is known to be efficient in terms of availability, cost, and content. However, SCOBY based edible film need additional materials to improve its characteristics, some of them are CMC and glycerol. CMC is known to be able to increase the tensile strength of the film. On the other hand, glycerol was able to increase the elongation of the film, but was able to decrease the tensile strength of the film. This study aims to determine the optimal concentration of CMC and glycerol in edible film formulation with optimal mechanical characteristics. The research was conducted using the Simplex Lattice Design (SLD) method with two factors. The first factor is the concentration of CMC with a lower limit (0 level) of 1% and an upper limit (1 level) of 2%. The second factor is the concentration of glycerol with a lower limit (0 level) of 1,5% and an upper limit (1 level) of 3%. The responses tested include thickness, tensile strength, and elongation. The data were analyzed by ANOVA variance, then the most optimal treatment was selected and a validation test was performed. The optimal solution in the Design Expert program is found at a concentration of 2% CMC and 1,5% glycerol. The average results on testing the optimal solution obtained for each response include 3,23 N for tensile strength, 16,67% elongation, and 0,08 mm thickness. Based on the validation results, the concentration of CMC and glycerol have a significant effect on the tensile strength and elongation response of SCOBY-based edible films.
