Abstract
Hydrocarbon compounds contained in used motor vehicle oil waste are hazardous wastes. This study aims to determine the ability of fungal isolates to degrade hydrocarbon compounds in motor vehicle oil waste. The fungi used in this study consisted of 3 genus of fungi namely Aspergillus, Penicillium and Trichoderma. The fungal culture used in the biodegradation process consisted of a single culture and a consortium culture. The research method consisted of measuring the fungal population using the method of counting the number of molds and analyzing the content of hydrocarbon compounds with GC-MS (Gass Chromatography-Mass Spectophotometry). The results showed that there was fungal growth in the single culture and the consortium culture in the media added by 10% of used motor vehicle oil waste. GCMS results show that there is a change in the composition of motor vehicle oil waste from complex hydrocarbon compounds to simpler hydrocarbon compounds.
