A B S T R A C TThis article reports effect of vibration duration of high ultrasound applied to bio-composite while gelatinized on its properties. The bio-composite consists of mixing of both the tapioca starch based bioplastic and oil palm empty fruit bunch (OPEFB) fibers with high volume fraction. Gelatinization of the bio-composite sample was poured into a rectangular glass mold placed then in an ultrasonic bath with 40 kHz, and 250 watt in different duration for 0, 15, 30, 60 min respectively. The results show that vibration during gelatinization has changed the characterisation of the bio-composite. SEM photograph displayed different fracture surface of tensile sample. For vibration duration of 60 min, tensile strength (TM), and tensile modulus (TM) was improved to 64.4, 277.4%, respectively, meanwhile strain was decreased to 35.1% in comparison without vibration. Fourier Transform Infrared Spectroscopy (FTIR), and XRD diffraction of the bio-composite has changed due to various vibration duration. Moisture absorption of the vibrated bio-composite was lower than that of the untreated one.

“…Moreover, sago palm is a local plant in Nakhon Si Thammarat province of Thailand. The physical and chemical properties of sago starch are absolutely similar to those of commercial starches but in-between to those of potato and cereal starches (Nafchi et al, 2012).…”

The objective of this study was to investigate physical and mechanical properties, such as thickness, water vapor permeability, tensile strength, elongation at break, differential scanning calorimetry (DSC) and microstructure of composite edible films. The film was prepared by casting sago starch from sago palm (Metroxylon sagu) as film base with 10-50 %w/w glycerol as plasticizer and adding bulk chitosan as a reinforcing material (0.1, 0.3, and 0.5 %w/w). The continuous, homogenous and transparent films were obtained. With regard to mechanical properties, tensile strength decreased when the percentage of glycerol increased. Elongation at break (%E) improved with increasing percentage of glycerol from 10 %w/w to 50 %w/w. However, water vapor permeability properties diminished in all samples when the percentage of chitosan increased. The morphological study of the composite films exhibited rougher surfaces with increasing chitosan in the films. DSC thermograms showed that glycerol incorporated into composite films diminished the onset temperature (T0) and degradation temperature (Td). Having these physical and mechanical properties, this edible film has a potential to apply for food packaging purposes. Moreover, this edible film is proved to be more cost-effective and environmentally friendly.

Studi lain juga menyatakan bahwa permeabilitas uap air dari nanokomposit film pati terplastisasi gliserol/ ZnO ) dan pati sagu/ZnO (Nafchi et al 2012). Nilai WVTR film karagenan juga menurun secara signifikan oleh keberadaan komponen hidrofobik (beeswax) dalam matriks film.…”
