Water samples taken from rivers and estuaries stations in Bengawan Solo and Porong rivers in East Java were analyzed for the pollution of indicator bacteria in July-August and NovemberDecember 1984, to determine the influences of domestic wastes on the quality of these waters. Higher frequency of occurrences of high total coliform, fecal coli and fecal streptococci were observed in water samples collected in river stations, river mouths and in the vicinity of dense populated areas. The distribution of saprophytes, freshwater bacteria and indicator bacteria were also studied. The changes in the bacterial population as funciton of the salinity were shown during the observations. Some pathogenic bacteria like Salmonella, Yarsinia, and Vibrio parahaemolyticus and others have been isolated from waste and mud samples.

Jakarta Bay has been known as one of the most polluted marine environment in Indonesia, with no exception by oil. Seribu Islands waters, located in the north of Jakarta Bay may have been impacted by this polluted condition.Itâs sometimes also hit by oil spillage from pipe leakage. The purpose of this study is to isolate and identify hydrocarbonoclastic bacteria (oil and Polyaromatic Hydrocarbon degrading bacteria) from Jakarta Bay and Seribu Island waters. The bacteria were isolated from water and sediment/sand. Isolation was prepared by enriched samples in SWP medium with Arabian Light Crude Oil (ALCO). Screening for PAH degrading bacteria has been completed by using sublimation plate method in ONR7a medium and screening for oil degrading bacteria were conducted by using oil plated method with the same medium. Bacteria identifications were done based on l6sRNA gene. The results were analyzed using BLAST and showed that 131 potential hydrocarbonoclastic bacteria have been isolated from Jakarta Bay and Seribu Island waters. Most of them were oil degrading bacteria (41.98%) and the rest were PAH degrading bacteria. Oil pollution level may impact the number of strain of hydrocarbonoclastic bacteria isolated. Among the hydrocarbonoclastic bacteria isolated from Jakarta Bay and Seribu Islands, Alcanivorax, Marinobacter, Achromobacter and Bacillus were common hydrocarbonoclastic genera in Jakarta Bay and its surrounding waters. Alcanivorax spp. is important oil and PAH-degrader found not only in temperate waters, but in tropical waters as well.

Study of microbial pollution in the Aceh coastal waters and its vicinity were carried out in the period of August - September 2006. The purpose of the study is to monitor the marine and coastal environments related to the bacterial condition in Aceh waters after the tsunami disaster. The sediment and water samples were collected from 28 stations in four sites in the Aceh waters (Eastern Aceh, Northern Aceh, Western Aceh and Simeulue Islands waters), using the RV. Baruna Jaya VIII. The determination of microbial pollution was based on parameters of coliform and pathogenic bacteria. The coliform bacteria was analysed by membrane filter technique and pathogenic bacteria (Salmonella and Vibrio) by isolation method based on the selective culture media of Salmonella and TCBS agar. The results of the study showed that density of total coliform bacteria varied between 40 and 1055 CFU/100 ml with an average of 443 CFU/100 ml. Based on the pattern of the distribution of coliform bacteria it was found the highest number in Eastern Aceh with the value of 611 CFU/100 ml and the lowest number in Western Aceh with the value of 348 CFU/100 ml. Based on the density of coliform bacteria, Aceh waters was in the lower permissible level of the Indonesian and WHO standards, means that the coastal environment in Aceh waters is still in good condition. Four genera of pathogenic bacteria isolated from seawater samples were Pseudomonas, Citrobacter, Aeromonas and Proteus, and 6 genera from sediments samples were found i.e. Pseudomonas, Citrobacter, Aeromonas, Yersinia, Proteus and Vibrio. The pathogenic bacteria from the samples such as Salmonella typhy and Vibrioparahaemoliticus had low pathogenic potential. This indicated that the risk of pathogenic bacterial contamination in Aceh and its vicinity waters were relatively low, therefore, the conditions of coastal and marine environments were relatively in good condition.

The study of waters fertilization in Southeast Sulawesi include Flores Sea, Kabaena Strait, Muna Strait, Buton Strait and Tioro Strait based on bacteriological aspect was conducted on April–May 2006, using the Research Vessel Baruna Jaya VII with total stations 25. The aim of investigation was to find out the total numbers and pattern of distribution heterotrophic bacteria and productivity bacteria in the marine ecosystem of Southeast Sulawesi and related with waters fertilization. The analysis of heterotrophic bacteria was determined based on the Total Plate Count method, whereas bacterial productivity with Acridine Orange Direct Count method. The result indicated that the pattern of distribution and total numbers of heterotrophic bacteria at the surface layers varied between (10–10220)CFU x 10-1/ml with an average 940CFU x 10-1/ml. While at the bottom layer varied between (2–488)CFU x 10-1/ml with an average 91CFU x 10-1/ml. For the bacterial productivity in the form of Carbon biomass at the surface layers varied between (1.30– 5.84) x 10–7grC/m3 with an average 3.56 x 10–7grC/m3, at the bottom layer varied between (0.24–1.33) x 10–7grC/m3 with an average 0.64 x 10–7grC/m3. The result of numbers bacteria that in Southeast Sulawesi waters was lower than the Arafura Sea but still higher than the Aceh Sea. The fluctuation of numbers bacteria perhaps due to the factor of monsoon and environmental was influenced on the marine ecosystem. In general this paper conclude that the condition of marine ecosystem Southeast Sulawesi still relatively fertility.Keywords: Fertility, heterotrophic bacteria, productivity bacteria, Southeast Sulawesi waters
