Abstract

Biodegradable plastic is environmentally friendly plastic because it is easily degraded by microorganisms. This research aims to see how much influence the addition of virgin coconut oil additives has on the quality of bacterial cellulose-Glycerol based biodegradable plastic from coconut water (Cocos nucifera) which includes physical properties test (moistur content and swelling test), mechanical properties test (tensile strength, elongation and elasticity) and biodegradation test. This research uses 3.5% Glycerol as a plasticizer with varying volumes of virgin coconut oil, namely 2 mL, 4 mL, 6 mL and 8 mL. The results of the physical properties test obtained are that the % moisture content and swelling test decreases as the volume of virgin coconut oil increases. The maximum results from mechanical properties testing obtained a tensile strength value of 118.97 MPa with variations in the addition of 6 mL virgin coconut oil, where the tensile strength value already complies with the SNI standard for synthetic plastics, namely in the range 24.7-302 MPa, , the elastic value obtained is 3571.15 MPa, and the elongation value is 5.28%. For the biodegradation test, the plastic that was added with virgin coconut oil experienced a decrease but on the 15th day this plastic has fully degraded.

Abstract

Abstract -Electrical energy is energy that is really needed by humans, one way to save electrical energy is to use the thermoelectric method. Thermoelectric materials are materials that can convert heat energy into electrical energy through the Seebeck effect. This research aims to determine the effect of the size of the Active Carbon/Cuo composite material with a high Seebeck coefficient and apply it as a thermoelectric generator. In this study, variations in the size of the mold material were carried out with thickness (0.5 0.8 1 1.3 and 1.5) cm, width (1 1.3 1.6 2.5) and length 5 cm. From the research results, it can be seen that materials with sizes of 0.5 cm and 1 cm have the highest thermal conductivity, namely 0.195 mS.cm-1 and 0.0964 mS.cm-1, the lowest thermal conductivity is 0.06J/s and 0.08J/s, and the highest electrical voltage (Seebeck effect), namely 0.02 mV/K and 0.012 mV/K. Furthermore, applying this material to a generator is capable of producing an electrical voltage of 1.7V at a temperature of 80℃.

Abstract

This research aims to determine the effect of the width of the C-CuO composite mold on the characteristics of thermoelectric materials. The composite is made from activated carbon mixed with CuO in a ratio of 3 grams of activated carbon: 7 grams of CuO which is then molded with five variations in the width of the mold for the C-CuO composite, namely 1 cm, 1.3 cm, 1.6 cm, 2 cm and 2.5 cm. In testing the electrical conductivity and Seebeck effect on the C-CuO composite, the values were almost the same, in other words the electric current produced was not influenced by the mold width of the C-CuO composite. Meanwhile, on the heat conductivity day value, the mold width has an influence as the applied temperature increases. Where the optimum heat conductivity value is produced in material with a width of 1 cm.

Abstract

Plastic is one of the most commonly used materials in society. The accumulation of plastic waste has a negative impact on the environment and human health. To mitigate these effects, there has been a shift toward environmentally friendly packaging. Biodegradable plastic is an eco-friendly material because it can be easily degraded by microorganisms. This study aims to investigate the effect of varying CaCO3 additive concentrations on the quality of biodegradable plastic based on bacterial cellulose-sorbitol from coconut water. The study includes testing mechanical properties, biodegradability, and analysis using FTIR and XRD instruments. In this research, 30% sorbitol was used as a plasticizer, and CaCO3 was added in varying amounts: 2 g, 4 g, 6 g, and 8 g. The results of the mechanical property tests showed a tensile strength of 179.85 MPa at 8 g of CaCO3 addition, which meets the SNI (Indonesian National Standard) range for conventional plastic (24.7–302 MPa). The elasticity was 906.21 MPa, and the elongation value was 31.50%. Biodegradability tests revealed that plastic with CaCO3 showed increased degradation, with 90% degradation observed by day 15. FTIR functional group analysis showed no new functional groups, while XRD analysis indicated that the addition of CaCO3 increased the crystallinity of the plastic to 96.92%, compared to 95.79% for bacterial cellulose-sorbitol without CaCO3.
