“…The influence of bamboo leaf powder content The addition of bamboo leaf powder in 0, 1, 3, 5, and 7% (w/w) significantly increased the tensile strength with a slight improvement in elongation. The higher value of elongation at break in bioplastic indicates it is more deformable [12]. The results also showed that the elongation percentage of bioplastic in various ratios of glutinous rice starch and bamboo leaf powder was around 39.798-58.442% and met the plastic standard of SNI 7188.7:2016 (21 -220%) [25].…”

“…Generally, the hardness of most plastic materials is measured using a durometer scale of Shore D. Testing was carried out at 5 different points on the sample. The hardness value of the bioplastic is expressed as the average of the measurement results [12].…”

“…The hardness value also was influenced by the thickness of bioplastics. Consequently, the higher bioplastic thickness causes an increase in the hardness value, which shows the response of the material under compressive load [12].…”

<p class="E-JOURNALAbstractBodyEnglish">Plastics are widely used in various aspects of life due to their variety of superior properties. However, they contribute a negative impact on the environment, which leads to the search for an alternative solution such as the production of bioplastics as biodegradable plastics. Therefore, this study aims to evaluate the psycho-mechanic quality of bioplastic from glutinous rice starch reinforced with bamboo leaf powder. The bioplastic synthesis process was carried out using 0, 1, 3, 5, and 7% (w/w) variations of bamboo leaf powder on glutinous rice starch, respectively. The results showed that the best bioplastic composition was the addition of 3% (w/w) bamboo leaf powder to glutinous rice starch. This indicated that the addition of bamboo leaf powder in bioplastics can enhance the thickness, hardness, and tensile strength significantly. Meanwhile, the value of density, water vapor transmission rate, and elongation showed a slight increase, and the bioplastic also degraded more than 70% for 7 days.</p>

“…The results produced denoted that even though the mechanical properties were not up to the mark that can be considered for basic-level bioplastics, but revealed that it had commendatory biodegradability properties (A.B.D. Nandiyanto et al 2020). In order to enhance the mechanical properties, it is necessary to incorporate additional reinforcing materials.…”

Plastic has become an inevitable part of our daily life. According to OECD (Organization for Economic Cooperation and Development), around 460 million tonnes of plastic is produced worldwide, of which merely 9% plastic waste gets recycled while 22% is mismanaged. This causes severe hazards to the environment and lifeforms. In order to overcome this problem, bio-plastics are introduced. They are considered green materials substitutes for plastics which are environment-friendly and biodegradable. Bioplastic can be prepared from renewable resources consisting of biomass mainly starch, cellulose, etc. This paper presents a detailed process of preparation of bioplastic from corn and potato starch followed by its mechanical strength testing. Also, the real-life applications of the obtained bioplastic are discussed. The bioplastic produced initially lacks plasticity so sorbitol was added as a plasticizer. The newly prepared bioplastic has higher elongation and less water absorptivity. Hence it can be concluded that the bioplastic obtained meets the requirement to be considered as an alternative to conventional petroleum-based plastic.
