Pollution of diesel oil in marine waters with low and high concentrations has a large enough impact, such as damage to marine ecosystems as well as the emergence of contaminants that can accumulate in the bodies of marine organisms and are very dangerous if consumed by humans. One of the simple and inexpensive techniques to overcome this problem is the bioremediation technique. This technique utilizes microbes, especially local bacteria, in its use to convert harmful compounds into compounds that are less toxic to the environment. The use of bacteria obtained from polluted areas and the ability to produce biosurfactants and lipases are more effective in degrading diesel oil. Biosurfactants can accelerate the biodegradation process by facilitating contact between oil and microbes, while lipolytic bacteria will secrete lipases that can work at the interface layer. Lipolytic bacteria that produce biosurfactants can reduce interfacial tension. The purpose of this study was to determine the ability of local bacterial isolates with isolate codes ALP D1 and ALP E1 as well as a mixture of 2 isolates (a consortium of bacterial isolates) from oil-contaminated seawater at Panjang Port, Lampung in degrading diesel oil, with incubation times of 7 and 14. day. This study used the gravimetric method to determine the residual diesel oil content and % biodegradation. The results of this study indicate that each isolate can degrade diesel oil, it is known from the % biodegradation of diesel oil by each isolate has a different value. A consortium of bacterial isolates or a mixture of ALPD1 and ALPE1 isolates were known to have the highest relative ability to degrade diesel oil at 7 and 14 days of incubation, namely 64% at 7 days incubation and 77.5% at 14 days incubation.
