Abstract

This study aimed to investigate the the characteristics of biocellulose-based edible films from sago wastewater (Metroxylon sago ROTTB.) by incorporating varying concentrations of glycerol as a plasticizer. The edible films were made through a casting method using biocellulose from sago wastewater as the main ingredient. The treatments included the addition of varying glycerol concentrations to the edible films, namely 0.5, 1, and 1.5% (v/v), with three replications. The observed characteristics included physical (thickness, solubility, and moisture content of the film), mechanical (tensile strength, elongation percentage, and Young’s modulus/modulus of elasticity) with a universal testing machine, chemical structure using FT-IR, and surface morphological characteristics through scanning electron microscopy (SEM). The results showed that increasing the glycerol concentration in the edible films improved the physical characteristics including thickness, solubility, and moisture. However, there was a decrease in the mechanical characteristics, namely tensile strength, elongation percentage, and Young’s modulus of the film. The main components of edible films found were cellulose polymers, as indicated by characteristic functional groups, such as free-OH groups, aliphatic C-H, C-O, and β-1,4-glycosidic bonds. The surface morphology of the biocellulose edible film without glycerol was smoother compared to those containing glycerol. Biocellulose-based edible films from sago wastewater with glycerol concentrations of 0.5% and 1% showed physical-mechanical characteristics that fulfilled the Japanese Industrial Standard (JSI), indicating the potential for application as food packaging. These results indicated that incorporation of glycerol has an effect on the characteristics of the biocellulose-based edible films from sago wastewater.

Abstract

Kulit buah kakao (KBK) adalah limbah organik dari hasil olahan buah kakao yang dapat digunakan sebagai sumber senyawa aktif. Kulit kakao mengandung senyawa selulosa, hemiselulosa dan lignin yang dapat terdekomposisi menghasilkan senyawa fenolik. Penelitian ini bertujuan untuk menentukan kandungan fenolik total atau Total Phenolic Content (TPC) dari liquid volatile matter (LVM) hasil pirolisis KBK dan uji aktivitas antifungi terhadap Fusarium oxysporum. Produksi LVM dihasilkan dari metode pirolisis KBK pada suhu 500 °C. Penentuan TPC dengan metode spektrofotometri UV-Vis menggunakan pereaksi Folin- Ciocalteu (FC) pada panjang gelombang maksimum 765 nm dengan larutan standar asam galat dan diukur setelah dibiarkan selama 60 menit pada suhu kamar. Uji aktivitas antifungi terhadap F. oxysporum dilakukan dengan metode dilusi. LVM dari hasil pirolisis KBK adalah 25,80% (b/b) dengan TPC 100% sebesar 2,28 g/L. Pirolisis KBK menghasilkan LVM yang memperlihatkan aktivitas antifungi dengan konsentrasi hambat minimal (KHM) 1% (v/v) dan konsentrasi bunuh minimal (KBM) 9% (v/v). Oleh karena itu, LVM KBK memiliki potensi untuk diaplikasikan sebagai fungisida alami.Determination of The Total Phenolic Content of Liquid Volatile Matter from Cocoa Pod Husk Pyrolysis and Antifungal Activity Test Against Fusarium oxysporum. The cocoa pod husk (CPH) is an organic waste from the processed cocoa potentially used as source of active compounds. The CPH contains cellulose, hemicelluloses, and lignin compounds that can be decomposed into phenolic compounds. The present study investigated the determination of total phenolic content (TPC) of liquid volatile matter (LVM) of CPH followed by the antifungal activity test against Fusarium oxysporum. The LVM production was performed by the pyrolysis method at temperature of 500 °C. The determination of TPC was evaluated by the UV-Vis spectrophotometric method using the Folin-Ciocalteu (FC) reagent at maximum wavelength of 765 nm with the standart solution of gallic acid measured after 60 min reaction at room temperature. The antifungal activity test against F. oxysporum was carried out by dilution method. The pyrolysis of CPH produces LVM of 25.80% (b/b) contained TPC 100% of 2.28 g/L. The LVM produced in this study shows antifungal activity with a minimal inhibitory concentration (MIC) 1% (v/v) and minimum fungicidal concentration (MFC) 9% (v/v). Therefore, the LVM CPH produced can be applied as a natural fungicide.

Abstract

The increasing demand for plastic food packaging has raised concerns over the environmental impact of plastic waste. Previous research has used sago liquid waste as a primary food packaging material, namely, edible coatings on tomatoes and edible films on sausages. However, research on secondary food packaging has not been conducted. The method used in this research involves a series of stages, from synthesizing bacterial cellulose to make bioplastics. The bioplastics were made with bacterial cellulose fermented from sago liquid waste and mixed with varying compositions of carboxymethyl cellulose (CMC), zinc oxide (ZnO), polyvinyl alcohol (PVA), and glycerol. Chemical characteristics, as determined by functional group analysis, showed that bioplastics still exhibited the typical functional groups of bacterial cellulose, as well as additional groups from glycerol, CMC, PVA, and ZnO, indicating the success of chemical structure modification in bioplastics. The crystallinity level of bioplastics also increased with the concentration of the mixture, with the highest crystallinity value of 37.084% in bioplastic sample A4. The physical characteristics of bioplastics, such as transparency, thickness, moisture content, water solubility, water uptake, and water vapor transmission rate, increased with increasing bioplastic mixture.
