Analisis Sifat Mekanik dan Permukaan pada Degradasi Plastik Konvensional
Summary
An Indonesian study tested the degradation of biodegradable plastic materials under UV light, sunlight, and soil burial, measuring changes in mechanical properties and surface structure. The research contributes to understanding how biodegradable plastics perform in real-world environmental conditions compared to conventional plastics.
Currently, plastic waste that decomposes for a long time can damage the environment and natural ecosystems. therefore, an innovation was made to create an environmentally friendly plastic that decomposes faster in nature. The purpose of this research is to determine the degradation ability of environmentally friendly conventional biodegradable plastics. This research uses environmentally friendly conventional plastic materials. This plastic is degraded in 3 (three) ways, namely photodegradation (irradiation with UV C light), irradiation with sunlight, and biodegradation. Each degradation process lasts for 30 days. The research results showed that there was a decrease in the elongation at break value of plastic that had been degraded. This is caused by the breaking of bonds in the polymer chain. Apart from that, the plastic also experiences damage to its surface. This damage is characterized by cracks, the appearance of stains, and the appearance of mold or microorganisms on the plastic surface.
