Uji Kemampuan Bakteri Lokal Riau Dalam Mendegradasi Beberapa Kantong Plastik Berwarna

---

ABSTRACT
One of the most commonly found inorganic waste is plastic bags. Plastic is an inorganic waste that has constituent components that are difficult to decompose in nature. Plastic waste can be degraded in the environment by microorganisms such as bacteria. The use of microorganisms and the use of enzymes is an effective and environmentally friendly way. The purpose of this study was to test the ability of Riau local isolate bacteria in degrading several red, white, and black High Density Polyethylene (HDPE) plastic bags. Rejuvenation of bacterial isolates is carried out to ensure the isolates used are appropriate. The biodegradation test was based on the percentage weight reduction of HDPE plastic sheets on the medium for 30 and 60 days. The results showed that all isolates had HDPE biodegradation activity capable of degrading colored plastics within an incubation time of 30-60 days. The best percentage of weight reduction of test plastics was by LSSB 2.3, LSSB 3.3, and LSSB 4.1 isolates on red plastics with a percentage of weight reduction of test plastic sheets at 30-day incubation of 1.00-1.25% and at 60-day incubation of 2.30-2.65%. Biodegradation ability tests on Mineral Salt Medium (MSM) liquid medium tend to increase the pH value.
Key findings: Biodegradation, plastic, bacteria, High Density Polyethylene (HDPE), Riau local isolate.
