“…Until now, Tannia rarely been utilized as a bioplastic raw material, as well as for food. This is different from taro, which has been reported several times as raw material from both bioplastics and foods (Pramodrao, & Riar, 2014;Asria, 2016;Hasan et al, 2019).…”

The rate of biodegradation of cassava – tannia starch bioplastic in various media was evaluated. Bioplastic degradation profile for a period of 4 weeks was seen following the Hills Equation where the speed of bioplastic biodegradation in sand media had higher yields than farm soil and compost media with the value up to 98.84 %. This is also proven by measuring the rate of degradation reaction using a first order reaction rate, where the value of the constant rate of reaction from bioplastics in sand is a little bit higher compared to farm soil and compost media (0.77647, 0.67133, and 0.15779 week-1, respectively). According to SEM pictures, there were numerous bacteria (either aerobic or anaerobic) and fungal species on the bioplastic surface, which have a role in the biodegradability of the polymer in bioplastics. The FTIR spectra of bioplastic biodegradation showed a decrease in the peak at 3400 - 3200 cm-1, and loss of the peak was present in the control at 2900 cm-1 which showed a breakdown of the polymer chain in the bioplastic especially in the O-H and C-H bonds, respectively. It can be concluded that farm soil and sand are the most optimal media in the bioplastic biodegradation process, while compost has potential but its maturity must be considered.

“…The degradation tests of bio-films was Spectral Analysis of the Bio-films Figure 3 and 4 show the IR spectra of Cucurbita pepo and Musa paradisiaca. In the IR spectrum of Cucurbita pepo bio-film the characteristic peak at 3605.99 cm -1 shows the presence of O-H stretching bond 20 , the peak at 2326.18 cm -1 shows O=C=O stretching bond 21 , the absorption bands at 2155.99 cm -1 and 1743.92 cm -1 shows the presence of N=N=N and C=O stretching and the band at 1472.50 cm -1 shows C=C ring stretching aromatic bond. The characteristics peaks at 3205.90 cm -1 , 2957.66 cm -1 , 2132 cm -1 , 1421 cm -1 and at 857 cm -1 of the Musa paradisiacal biofilm were attributed to N-H stretching (secondary amine) hydrogenbonded nitriles, strong C-H stretching (alkanes) 22 , C≡Calkynes, C-H stretching (alkene) and aromatic C-H stretching respectively in the FT-IR Spectrum.…”

Cucurbita pepo and Musa paradisiaca can be considered as a large source of starch which makes it appropriate to be used for the preparation of bio-plastic material. In this study, biodegradable films from Cucurbita pepo and Musa paradisiaca were developed and investigated for their properties like pH, ash, moisture content, amylose content, biodegradability, and antimicrobial activity. 1,2,3-Propanetriol, gingelly oil, and agarose gel was used to reduce the brittleness of the developed starch- based bioplastic films. The investigation of films was done by Spectroscopic and Surface Analysis techniques. The developed bio- films showed substantial properties like less engorgement and insolubility in water which makes it worth a commercial viable product for food packaging.

“…Bioplastics are made from natural polymeric materials such as starch, cellulose, and fats (Amni et al, 2020;Hasan et al, 2019;Silviana & Subagio, 2019;Judawisastra et al, 2018;Suharty et al, 2014). However, bioplastic cannot completely replace the function of conventional plastic yet.…”

The purpose of this study was to improve the mechanical and physical properties, degradation performance, and water absorption of a thermoplastic mixture of sago starch with the addition of Linear Low-Density Polyethylene (LLDPE). The method used is the grafting method where polyethylene is grafted onto Maleic Anhydride (LLDPE-g-MA). In this research, Thermoplastics Sago Starch (TPSS) was made with a mixture of Sago Starch (65%) and Glycerol (35%), added with water as a solution. Compatibilizer (PE-g-MA) was made by reacting LLDPE (88%) and Maleate Anhydride (9%) with an additional initiator of Benzoyl Peroxide (3%). The concentration of LLDPE varied from 10,15, 20, 25, and 30%. Substances were mixed into an internal mixer Thermo Haake Polydrive with a speed of 100 mm/minute, for 15 minutes. The concentration of 30% LLDPE produced the highest tensile strength and elongation at a break of 4.30 N/mm2 and 2.15%, respectively. Simultaneously, as LLDPE concentration increased, Young's Modulus decreased. This was powered by the morphology of the sampling surface, with the occurred reaction of adhesion interface or dispersion of LLDPE toward the whole surface with the assistance of compatibilizer as connecting substance between hydrophilic polymer and a hydrophobic polymer, which could improve the properties of mechanical. The formation of ester groups from the reaction of inter groups of hydroxyls derived from the starch with the groups of anhydride derived from the mixture of compatibilizer was visibly seen at the peak of 1693 cm -1 . The degradation performance of the TPSS: LLDPE mixture with a ratio of 70:30 showed good performance where the degradation continued to increase up to 42% on the 30th day of degradation in freshwater, 18% in seawater, and 17% in soil burial. While the water absorption test showed that the higher concentration of LLDPE, the lower speed of water absorption.
