Background: Jackfruit (Artocarpus Heterophyllus) is a tropical fruit that has high amylose content in its seeds similar to sago starch. Thus, jackfruit seeds and sago are suitable raw materials for the production of biodegradable plastic (BGP). Objective: The objective of this research is to investigate the physical and mechanical properties of BGP produced from the blend of jackfruit seed and sago starch. The BGP was prepared by mixing different ratios of the jackfruit seed flour to the sago flour in distilled water with the addition of 0.1 M hydrochloric acid (HCl). The mixture was stirred and heated at 80 °C and later mixed with glycerol. The mixture was neutralized with 0.1 M sodium hydroxide (NaOH) and was casted by using casting plate technique Results: The results showed that the optimum tensile strength was was obtained at 2.06 MPa. at the blend ratio of 7:3. The maximum absorption rate of water ranged from 32 % to 34 % occurred at the blend ratio of 1:9 while the lowest absorption rate ranged from 21% to 26% occurred at the blend ratio of 5:5. The degradability of BGP was indicated by decreasing of the FT-IR spectra peaks intensity and broadening of the bandwidth due to degradation of starch in the BGP. Conclusion: The blend ratio of 10:0 showed the highest degradability rate. Conclusively, that the physical and mechanical properties are affected by the blend ratios.

Polybutylene Succinate

The need for utilization of environmentally friendly materials has emerged due to environmental pollution that is caused by non-biodegradable materials. The usage of non-biodegradable plastics has increased in the past decades in many industries, and, as a result, the generation of non-biodegradable plastic wastes has also increased. To solve the problem of non-biodegradable plastic wastes, there is need for fabrication of bio-based polymers to replace petroleum-based polymers and provide strategic plans to reduce the production cost of bioplastics. One of the emerging bioplastics in the market is poly (butylene succinate) (PBS) and it has been the biopolymer of choice due to its biodegradability and environmental friendliness. However, there are some disadvantages associated with PBS such as high cost, low gas barrier properties, and softness. To lower the cost of PBS and enhance its properties, natural lignocellulosic fibers are incorporated into the PBS matrix, to form environmentally friendly composites. Natural fiber-based biocomposites have emerged as materials of interest in important industries such as packaging, automobile, and construction. The bonding between the PBS and natural fibers is weak, which is a major problem for advanced applications of this system. As a result, this review paper discusses various methods that are employed for surface modification of the Fibers The paper provides an in-depth discussion on the preparation, modification, and morphology of the natural fiber-reinforced polybutylene succinate biocomposites. Furthermore, because the preparation as well as the modification of the fiber-reinforced biocomposites have an influence on the mechanical properties of the biocomposites, mechanical properties of the biocomposites are also discussed. The applications of the natural fiber/PBS biocomposites for different systems are also reported.

Nuclear technology can be applied not only as an energy (electricity) but also in industry as as an initiator on polymer reaction. Tapioca waste is used due to its biodegradability properties. Tapioca waste gel is formed by adding equal aquades ratio to waste weight. After gel formed, several concentrations of methyl methacrylate (w/w) is added to the gel then packed into 150 mL ampule. Using Co-60 gamma irradiation source, gel is irradiated at 5 kGy absorbed dose. Gel is extracted using acetone to get rid of sample from impurities. Glycerol as a plasticizer is added to the gel to increase polymer flexibility. Gel-Glycerol mixing is done at 60ºC, 250 rpm for one hour by adding aquadest. To analyze mechanical properties, firstly, we need to mold samples using pressurized-hot press machine. Film is formed to type 5 specimen (dog bone, astm d638-14). Specimen is tested by analyzing tensile strength characteristics. Fabrication of biodegradable plastic based packaging by using starch has an increasement of mechanical and thermal properties at 5 kGy absorbed dose. Methyl methacrylate 25, 50, 75, 100, 125 and 150% addition to the solution has 10-24 MPa tensile strength. Gel fraction has range between 88-100%. Even the lowest ratio of monomer addition can provide highest gel fraction to improve mechanical properties of tapioca waste.

Biodegradable plastic (bioplastics) is a polymer that can be degraded and made from renewable sources, including cellulose obtained from pineapple leaves. The purpose of this study is to determine the mechanical properties of bioplastics from cellulose, determine the optimum conditions based on the concentration of chitosan variations on cellulose solution and the addition of glycerol plasticizers to the mechanical properties of biodegradable plastic produced. This study begins with the manufacture of cellulose from pineapple leaves through a process of delignification and bleaching and then making biodegradable plastic 1% cellulose raw material with a variation of chitosan with a variation of 1%; 2%; 3% and the addition of plasticizer glycerol 1%, 2% and 3% (v/v). The results obtained will be observed by tensile tests, SEM tests, swelling tests, and biodegradation. The results obtained in the morphological test with the SEM test showed that cellulose was not evenly distributed. The tensile strength test for the addition of chitosan showed that the concentration of 3% had the highest tensile strength value of 11.8 MPa while the tensile strength of the addition of glycerol showed that the concentration of 3% had the highest tensile strength value of 3.6 MPa. The swelling test shows that glycerol concentration influences biodegradable plastic water resistance and glycerol 3% has the highest percentage of water resistance, 16.6%. In the biodegradable plastic degradation test with 3% glycerol experiencing the fastest degradation, this shows that glycerol has an effect on biodegradable plastic degradation
