There is an information how to identify hydrocarbon degrading bacteria for bioremediation of marine oil spill. We have Bioremediation treatment for degradation of oil spill on Pari island and need two kind of experiment there are tanks experiment (sampling 0 to 90 days) and semi enclosed system (sampling 0 to 150 days). Biostimulation with nutrients (N and P) was done to analyze biodegradation of hydrocarbon compounds. Experiment design using fertilizer Super IB and Linstar will stimulate bacteria can degrade oil, n-alkane, and alkane as poly aromatic hydrocarbon. The bacteria communities were monitored and analyzed by Denaturing Gradient Gel Electrophoresis (DGGE) and Clone Library; oil chemistry was analyzed by Gas Chromatography Mass Spectrometry (GCMS). DNA (deoxyribonucleic acid) was extracted from colonies of bacteria and sequence determination of the 16S rDNA was amplified by primers U515f and U1492r. Strains had been sequence and had similarity about 90-99% to their closest taxa by homology Blast search and few of them suspected as new species. The results showed that fertilizers gave a significant effect on alkane, PAH and oil degradation in tanks experiment but not in the field test. Dominant of the specific bacteria on this experiment were Alcanivorax, Marinobacter and Prosthecochloris. Keywords: Bioremediation, Biostimulation, DGGE, PAH, Pari Island

The potential of the natural tourist attraction of Siwang Paradise will have a high attractiveness value if it is supported by the role of stakeholders in management and development. The purpose of this study is to analyze the role of stakeholders in the management and development of the natural tourist attraction of Siwang Paradise, and what obstacles are experienced by stakeholders in optimally managing and developing these objects. The method used is descriptive qualitative, the determination of respondents is based on snowball sampling technique, the analysis is carried out inductively based on facts and the results of interviews with respondents and key actors. The results showed that the stakeholders involved in the management of the Siwang Paradise object were the key actors (area owners) and the main actors (surrounding communities). Constraints in the management of the Siwang object are due to the lack of trust within the area owner to involve supporting stakeholders, in this case the private sector, NGOs, and academics. So that the management of objects in developing various readiness of tourist attraction products becomes slow and runs not optimally. The visible impact of the management is the economic impact, through increasing family income, social impact, reducing unemployment, opening up road access, making motorcycle taxis easier to use, making it easier for people to do their activities. While the ecological impact is the management is carried out by paying attention to the cleanliness of the environment from waste, and based on the carrying capacity of the object area.

Developing fast and accurate fluorescence detection technology of oil spill is significant for quantitative analysis in unexpected oil spill events. As the oil sample concentration increases, the fluorescence spectrum produces red-shift behavior, which seriously affects the quantitative detection of concentration. In this work, a three-dimensional concentration-emission matrix (CEM) was constructed by using a series of emission spectra with different levels of concentration at the excitation wavelength of 266 nm. The database is the interpolated CEM of six samples using bicubic interpolation in the concentration dimension. With matrix similarity matching, the database was used to achieve quantification of the concentration of oil samples. The recovery rates of prediction for test samples and weathering samples of six oil samples were between 86.8% and 116.11%, with relative errors of predictions ranging from 2.09% to 15.2%. The results show that this method can provide accurate quantitative determination of the concentration of different oil samples.

Dispersants, like COREXIT, are used for oil spill cleanups. This analytical method could aid scientists in identifying specific dispersant mixtures.
