Abstract

Aims: The aim of this study was to determine the effect of the addition of the type of bacterial consortium, incubation time, interaction between the types of bacterial consortium and incubation time on the number of bacteria (CFU/g-soil), oil sludge content (g/g-soil), percentage degradation of oil sludge in the best treatment, the ratio of C/N at week 6, as well as hydrocarbon components. Methodology and results: This research is a laboratory experimental study that used a completely randomized design with an 8 × 4 factorial pattern with two replications. For data analysis, logarithmic data of total bacterial plate count (CFU/g-soil), gravimetric results of oil sludge (g/g-soil) and degradation percentage were analyzed descriptively and statistically. The results showed that the percentage of degradation in the best treatment, namely the treatment of a consortium of biosurfactant-producing bacteria (B) was 77.8% and the time was after six weeks of incubation period. The C/N ratio at the end of the 6-week incubation period ranged from 70.5-102.1. While the hydrocarbon components that can be degraded in the treatment of a consortium of biosurfactant producing bacteria (B) are Naphthalene, 2,3,6- trimethyl, Naphthalene, 1,4,6-trimethyl and Naphthalene, 1,6,7-trimethyl. Conclusion, significance and impact of study: The type B consortium treatment produced the best results in decomposing oil sludge-contaminated soil. Research findings indicate that the kind of consortia B has the potential to be employed as a consortium to degrade oil sludge or other waste with similar characteristics.
