Uji Kemampuan Bakteri Lipolitik Lokal Riau Dalam Mendegradasi Plastik HDPE Dan LDPE

---

One of the inorganic wastes that is often found is plastic. The plastic material most widely used for packaging is plastic based on polyethylene. Increasing consumption of plastic can become waste and can pollute the land environment because the nature of plastic is not easily degraded naturally. Plastic waste can be degraded in the environment by decomposing microorganisms such as bacteria. Utilizing enzymes possessed by bacteria is an effective and environmentally friendly method. The aim of this research was to test the ability of local Riau lipolytic bacterial isolates to degrade High Density Polyethylene (HDPE) and Low Density Polyethylene (LDPE) plastics. Biodegradation test was seen based on gravimetric analysis, namely the percentage reduction in weight of plastic sheets in Mineral Salt Medium (MSM) which was incubated for 30 days at room temperature and qualitative analysis of changes in biochemical compounds using Fourier Transform InfraRed.The results showed that both isolates had plastic biodegradation activity during the incubation period. The best percentage reduction in weight of the tested plastic was LSSB 2.2 isolate, namely 1,20% on HDPE plastic and 0,44% on LDPE plastic compared to LSSB 1.1 isolate, namely 0,64% on HDPE plastic and 0,16% on LDPE plastic. The results of FTIR analysis at an incubation time of 30 days showed changes in wave numbers between the control and treated isolates that were analyzed still in the same functional group and a decrease in the percentage of transmission.
Key findings: Biodegradation, bacteria, Fourier Transform InfraRed, HDPE, LDPE, Riau’s local isolate.
