dc.description.abstractSynthetic plastic has the disadvantage of being difficult to decompose in nature, causing environmental problems. To overcome the problem of accumulation of plastic waste, the use of environmentally friendly plastics (bioplastics) is one solution. Bioplastics are made from natural polymers such as starch, cellulose, and fats. Polyhydroxyalkanoate (PHA) is one of the building blocks of bioplastics. PHA is the result of microbial metabolism produced by bacteria as a response to an unbalanced environment. Bacteria that have the ability to produce PHA can be isolated from various sources such as industrial waste, agricultural waste and soil. This study aims to isolate PHA-producing bacteria from peat soil, Bengkalis, Riau and optimize PHA production through modification of production media. Peat soil samples were taken from six types of locations with four replications, namely, industrial plantation forest, restoration land, rubber plantation, secondary forest, oil palm plantation and burnt land. Isolation was carried out using the spread plate method and qualitative selection of PHA-producing bacteria was carried out using suddan black dye. A total of 10 bacterial isolates had a high ability to produce PHA which was indicated by the black color absorption. The highest accumulation of PHA was 46.47% of HS4_8 isolates using 50% LCPKS enriched medium.en_US
