Abstract
Molds are heterotrophic organisms with cell walls composed of chitin and exhibit a cosmopolitan nature. Molds have functional structures and enzymatic activities that make them potentially useful for further applications. One such application is addressing the plastic waste problem at the Piyungan Waste Management Site (TPST Piyungan). Therefore, the aim of this study is to determine the potential of mold isolates from TPST Piyungan in degrading LDPE plastic waste. The isolation was carried out using the serial dilution method with plastic samples obtained from two stations in the Transition Zone of TPST Piyungan. The isolation results yielded eight mold isolates, namely suspected Cunninghamella sp., Cladosporium sp., Penicillium sp.1, Aspergillus sp., Scopulariopsis sp., Penicillium sp.2, Penicillium sp.3, and Nigrospora sp.. The potential of these isolates as biodegradation agents was analyzed through a degradation test, which showed that the suspected Penicillium sp.3 isolate produced the highest percentage of biodegradation, making this isolate the most effective for degrading LDPE plastic.
