Synthesis and Characterization of Eco-Friendly Bio-Composite from Fenugreek as a Natural Resource

Abstract

The present study show the usability of starch (tamarind) based-bio-composite film reinforced by fenugreek by various percentages to replace the traditional petrochemical plastics. The prepared bio-composite films were systematically characterized using the universal testing machine (UTM), soil degradation, scanning electron microscope (SEM), X-ray diffraction (XRD), thermogravimetric analyzer (TGA), and antibacterial tests. The experiments showed that a lower percentage of fenugreek improves biodegradation and mechanical strength. More than 60% of biodegradation occurred in only 30 days. Almost 3 N/mm2 tensile strength and 6.5% tensile strain were obtained. The presence of micropores confirmed by SEM images may accelerate the biodegradation process. Antibacterial activity was observed with two samples of synthesized bio-composite, due to photoactive compounds confirmed by FTIR spectra. The glass transition temperature was shown to be higher than the room temperature, with the help of thermal analysis. The prepared bio-composite containing 5% and 10% fenugreek showed antibacterial activities.

Peningkatan Karakteristik Biokomposit Pektin Kulit Jeruk dan TiO2

“…Hasil kuat tarik dan modulus young meningkat setelah ditambahkan pati dioscorea hispida (DHS) dan kandungan biofiller yang optimal adalah 6%. Berdasarkan hasil biokomposit dari fenugreek yang dilakukan oleh Hossain et al (2022), Diperoleh data bahwa konsentrasi fenugreek yang lebih rendah dapat meningkatkan kekuatan mekanik dan biodegradasi 60% dalam masa 30 hari, kekuatan tarik 3 N/mm2, dan elongasi 6,5%. Popov et al, (2022) menyatakan bahwa campuran 1,5% pektin apel dan 0,5% karagenan menghasilkan hidrogel yang mempengaruhi sifat biokompatibilitas in vitro gel bead.…”
