Abstract

The Belawan Sea, located in Medan, Indonesia, is a potential source of yeast that can degrade diesel oil. This study aims to isolate yeast from the sea water and test its ability to degrade diesel oil. The isolation process was carried out using the Salt Solution Stone Mineral Media (SMSSE) enriched with yeast extract and added 2% diesel oil. The results showed that three yeast isolates, namely GBN.1, GBN.2, and GBN.3, were obtained. These isolates were then tested for their ability to degrade diesel oil with a concentration of 1% and 3% through gravimetric analysis. The results showed that the isolate mixture (consortium) has better degradation capability than a single isolate. The consortium succeeded in degrading 68% of diesel oil at a concentration of 1% and 65% at a concentration of 3%. Statistical analysis showed that GBN.2 has the best potential in degrading diesel oil. This research has several important implications, including the discovery of a sea yeast that can degrade diesel oil, the use of the dozen consortium, and the identification of GBN.2 isolates as a yeast with the best degradation potential.

Introduction

The Belawan Sea, located in Medan, Indonesia, is a potential source of yeast that can degrade diesel oil. Diesel oil spills have become a major environmental problem, causing damage to ecosystems and human health. Bioremediation technology is a promising approach to clean up the environment from diesel oil pollution. This study aims to isolate yeast from the Belawan Sea and test its ability to degrade diesel oil.

Materials and Methods

The isolation process was carried out using the Salt Solution Stone Mineral Media (SMSSE) enriched with yeast extract and added 2% diesel oil. The process took place at room temperature and was stirred with a speed of 120 rpm. Three yeast isolates, namely GBN.1, GBN.2, and GBN.3, were obtained. These isolates were then tested for their ability to degrade diesel oil with a concentration of 1% and 3% through gravimetric analysis.

Results

The results showed that the isolate mixture (consortium) has better degradation capability than a single isolate. The consortium succeeded in degrading 68% of diesel oil at a concentration of 1% and 65% at a concentration of 3%. Statistical analysis showed that GBN.2 has the best potential in degrading diesel oil.

Discussion

This research has several important implications. First, the discovery of a sea yeast that can degrade diesel oil opens opportunities to develop effective and environmentally friendly bioremediation technology. Second, the use of the dozen consortium shows that interactions between yeast species can increase the efficiency of degradation. Third, the identification of GBN.2 isolates as a yeast with the best degradation potential can be a starting point for further research to optimize the ability of this yeast degradation.

Conclusion

This research makes an important contribution in efforts to find solutions to overcome environmental pollution due to oil spills. Belawan Sea yeast has the potential to become an effective bioremediation agent for cleaning up the environment from diesel oil pollution. Further research needs to be done to study the mechanism of diesel oil degradation by this yeast and to explore the potential for its application in the field.
