“…Research on the manufacture of edible films from starch with the addition of glycerol and zinc oxide is still a little done. Several previous studies that have used zinc oxide concentrations in the manufacture of edible films included sweet potato starch (Ervan, 2012), gadung tuber starch (Saputra et al, 2019), tapioca and corn ampok (Rahmatunisa, 2015), cassava starch (Ridwan, 2018), and soy protein (Putri et al, 2018). Several studies have revealed that there is an effect on changing characteristics from each addition of concentration or amount of ZnO nanoparticle.…”

Minimally processed jackfruits can usually be found in traditional markets, but the fact found that jackfruit is sold unpackaged and the fruit is not fresh, some have even browned and are infested with flies. Refrigerator is usually applied, but this technology is relatively expensive and not all farmers/traders can afford it. Edible film is an alternative that is easily degraded and decomposed by natural composers plus zinc oxide (ZnO) which is a piezoelectric ceramic that has anti-microbial properties. The purpose of this research was to determine the effect of ZnO concentration on the characteristics of edible films and to determine the best concentration of ZnO and its effect on packaging in jackfruit. Variations in the concentration of ZnO used 0%, 3%, 9% and 12%. Observations on jackfruit were carried out at room temperature. Results showed the higher the concentration of ZnO, the better the ability of edible films with ZnO to maintain the quality and shelf life of jackfruit. Edible film with 12% ZnO was able to extend the shelf life of processed jackfruit for at least 5 days at room temperature .

Biofoam material has been made for application of styrofoam substitute food packaging material from a mixture of raw materials: taro leaf powder and PVAc through a hot compaction method with variations of the composition of taro leaf powder: PVAc (80:20)% wt, (75:25)% wt, (70 : 30)% wt, (65:35) wt%, (60:40) wt%, (55:45)% wt, (50:50)% wt and (45:50)% wt. The first stage of taro leaves was blended and sifted with 100 mesh particle size. The second stage of the leaf powder of taro mixed with wet mixing was then mixed with PVAc as a matrix. The third stage of the homogeneous mixture was then put into the mold then compressed by heat to make it more dense with a pressure of 100 MPa and held for 10 minutes at 60 oC. Each biofoam sample that is ready to be characterized includes: physical properties (density, water absorption, functional groups and biodegredability), mechanical properties (tensile strength, elastic modulus, and elongation) and thermal properties (melting points). The characterization results showed that taro leaf powder: the optimum PVAc was (45: 55) wt% with a density value of 0.744 x 103 kg/m3, water absorption capacity of 1.765%, composed of OH and CH groups of PVAc and cellulose and C = C groups of lignin so that it has degrading properties of 91.2% for 50 days. Mechanical properties with tensile strength of 0.357 MPa, elastic modulus of 1.449 MPa, and elongation of 246.416%. Thermal properties with a melting point of 350.21 oC whose results have met the standards of conventional brand Synbra Technology. The results of biofoam material based on composite taro leaves and PVAc can be applied as food packaging.

Biodegradable Foam (Biofoam) production is an effort to reduce plastic waste in Indonesia. This product is made to replace Styrofoam, whose raw material is carcinogenic in the form of styrene which cannot be dissolved by the digestive system and is difficult to excrete through urine or feces which can trigger the growth of cancer in the long term and is harmful to the environment. Biofoam in this study is made from cornstarch with the addition of cellulose taken from paper waste. Based on the research that has been done, cornstarch-based biofoam with the addition of cellulose from paper waste as a biofiller can affect the physical and mechanical characteristics of the biofoam produced. The biofoam with a starch:cellulose ratio of 13:10 grams resulted in the best value of water adsorption in the amount 47.26%, also give the best result on tensile strength value and biodegradability value in the amount of 4.548 MPa and 11.943%. The addition of cellulose to the biofoam mixture in an appropriate amount will reduce the water absorption value of the biofoam. Because cellulose can cover the cavities generated by the starch expansion process in the biofoam. Therefore, the addition of cellulose also affects the mechanical properties of biofoam, namely tensile strength. Where the low filler composition in the biofoam will increase the tensile strength, but when the filler composition has passed an optimum point, the filler particles will experience agglomeration thereby reducing the tensile strength of the biofoam product. The variation in operating conditions in the manufacture of starch-based biofoam with the addition of a biofiller in the form of cellulose from paper waste did not significantly affect it. The variation in operating conditions only affects the visual appearance of the biofoam produced. Biofoam samples with the best visual appearance were produced at an operating temperature of 160 ? with an operating time of 30 minutes. Where high temperatures can affect th
