Phytoplankton in the ocean has an important role in forming the base of food chain, responsible in primary production. Its abundance and number of phytoplankton species will indirectly affect the level of water’s fertility. This study aimed to determine the presence of phytoplankton as bio-indicators of water quality in terms of abundance, diversity index, uniformity index, and saprobic coefficient in coastal waters of South Sumatera. The study was conducted on May 2013 - February 2014, at ten stations during high and low tides. Phytoplankton samples were taken vertically using plankton nets, cone-shaped with a diameter of 30 cm, length 100 cm and mesh size 30 μm. The study found 41 genera of phytoplankton, consisted of family Bacillariophyceae (26 genera), Dinophyceae (7 genera) Cyanophyceae (7 genera) and Chlorophyceae (1 genus). The highest number of genera was recorded while low tides in November (24 genera), and the lowest was on May while high tides (16 genera). The highest abundance of phytoplankton was recorded in August during high tides (2,68 x 107 cell.m-3), and the lowest was in May during high tides (6,59 x 105cell.m-3). The diversity index (H'), the uniformity index (E), and the dominance index (D) ranged between 0,64–3; 0,15–0,71 and 0,15–0,83 respectively. Keywords: phytoplankton, abundance, diversity index, South Sumatera coast.

Fish is one of the protein sources for humans which its existence is susceptible to the contamination, one of which is the heavy metal. The lack of information regarding the content of heavy metal in the edible fish in South Sumatera makes this study important to be done. This study was aimed to analyze the concentration of heavy metal in two species of edible fishes at Musi River Estuary site. The study was conducted in the estuary section of Musi River from September to November 2014. The heavy metals of Cu and Pb in the water and in the fish organs were analyzed using AAS with a type of SpektrA A-20 Variant Plus using a mixture of Air-Acetylene flame. The result showed the variation of Cu and Pb concentrations in each of species and three organs observed. The concentration of Cu and Pb in the liver was higher than in the gills and the muscle (liver>gills>muscle). The concentration of Cu and Pb in the muscle of all fish species were not exceed the safe limit for consumption. Keywords: Cu and Pb, consumed fish, Musi River estuary

Dissipation of internal tides will cause mixing, The mixing process at sea plays a key role in controlling large-scale circulation and ocean energy distribution. The purpose of this research was to estimate the turbulent mixing values (vertical eddy diffusivity) of water mass using Thorpe analysis. The results showed that the location where strong mixing occurred in the “near-field” area around Sangihe Island with vertical diffusivity value . Even in areas far-field(far from the generating site) are found vertical diffusivity , the result of internal propagation tides dissipation. Based on the result of the observation, it shows that the level of kinetic energy of eddy turbulen dissipation (ε) in the Sulawesi Sea on all layers has an average value of . The value of ε in the thermocline layer is greatest compared to the mixed surface layer and the almost homogeneous deep layer, the increase in mixing in the area near the ridge due to the closer water column to the base topography. The average turbulent rate of , the strongest fluctuation of value occurs in the thermocline layer, ranging from to with an average of about . The value of this turbulent mixing is higher than the previous measurements in some Indonesian ocean. This is allegedly due to the existence of a strong internal tidal energy and its interaction with topography in the Sulawesi Sea.Disipasi dari pasang surut internal akan menyebabkan terjadinya percampuran, proses percampuran di laut memainkan peran kunci dalam mengendalikan sirkulasi skala besar dan distribusi energi lautan. Tujuan dari penelitian ini adalah untuk mengestimasi nilai percampuran turbulen (difusivitas eddy vertikal) massa air dengan analisis Thorpe. Hasil penelitian ini menunjukkan bahwa percampuran yang kuat terjadi di area sekitar Pulau Sangihe-Talaud dengan nilai difusivitas vertikal . Bahkan pada area yang jauh dari pusat pembangkitan ditemukan difusivitas vertikal , hasil disipasi propagasi pasang surut internal. Berdasarkan hasil pengamatan menunjukan bahwa rata-rata tingkat energi kinetik disipasi turbulen eddy Laut Sulawesi pada semua lapisan adalah . Nilai di lapisan termoklin paling besar dibandingkan dengan lapisan permukaan tercampur dan lapisan dalam yang hampir homogen, peningkatan percampuran di daerah dekat ridge disebabkan makin mendekatnya kolom air dengan topografi dasar. Rata-rata nilai percampuran turbulen sebesar , fluktuasi nilai yang paling kuat terjadi di lapisan termoklin, yang berkisar yaitu antara sampai dengan rerata sekitar . Nilai percampuran turbulen ini lebih tinggi dibandingkan dengan pengukuran sebelumnya di beberapa perairan Indonesia. Hal ini diduga karena adanya energi pasang surut internal yang kuat serta interaksinya dengan topografi yang ada di Laut Sulawesi.

Bioremediation, involving biostimulation and/or bioaugmentation, is a promising method to overcome oil spills in Cilacap coastal waters. Cilacap coastal area has high risk on oil pollution. This study investigated the stimulatory effect of nitrogen concentration, bacterial density and the composition of bacterial culture in enhancing oil degradation in this area. The applications of 4 different concentrations of Slow Release Fertilizer (SRF) and 2 different densities of bacterial cells in the form of single (RCO/B/08_008) and mixed culture were employed in microcosm experiments for 28 days. The efficacy of combining bacterial culture and fertilizer application in various concentrations was also tested. Oil degradation, bacterial growth and environmental parameters were monitored periodically during the experiments. The results showed that oil degradation rate was more influenced by nutrient concentration (biostimulation) than bacterial number or culture composition (bioaugmentation) added. The efficacy of biostimulation in degrading oil was better than that of bioaugmentation. Biostimulation increased oil degradation up to 6.4 times higher than the control. The optimum of fertilizer concentration added was 7.5 mg N/g (C:N ratio of 1,000:75), which increased depletion rate both in biostimulation-only and the combination of biostimulation with bioaugmentation up to 6.4 and 7.5 times higher than the control, respectively. It is suggested that bioremediation of oil-contaminated sandy beach in Cilacap would be optimal by employing a combination of Slow Release Fertilizer at concentration having C/N ratio = 1,000 : 75 and RCO/B/08_008 culture at density of 0.5 x 108 cells/mL (100% homology with Alcanivorax sp. TE-9).

The current marine environment has begun to be polluted and will directly affect the biota around it. The study of health conditions and spatial variations in the characteristics of the population of Rhizophora apiculata was carried out in the mangrove ecosystem around the oil and non-industrial areas of Riau Province. This study aims at a baseline for evaluating mangrove management in Riau Province. Sampling is carried out using line transects drawn from the reference point (outermost mangrove stands) in a direction perpendicular to the coastline to the mainland and sample plots made with a size of 10 X 10 m2. Samples of leaves, fruits, and flowers are taken randomly based on the sample plots made. Then preserved with 70% alcohol and labeled. The preserved samples were taken to the laboratory to measure morphometrics and calculate the number of stomats. The results showed that the population of R. apiculata at all stations was in an unhealthy condition. In addition, individual competition and adaptability possessed by the population of R. apiculata are very low, ranging from 09.53 - 17.27% and illustrating more group growth and very high competition among individuals. Furthermore, the discriminant analysis shows that the morphometric variables that most characterize the population of R. apiculata in the oil industry with non-industrial areas are the length of the stem. Based on the results of PCA analysis, the variables that most determine the poor health of the population of R. apiculata are the parameters of Pb heavy metals, pH, temperature and DO waters.

Polycyclic Aromatic Hydrocarbons (PAHs) are the most toxic pollutants among the hydrocarbon families and their existence in the marine environment are harmful to aquatic organisms and human because of their mutagenic and carcinogenic properties. The purpose of this study was to identify the component of PAHs and their concentration in the water, sediment and their accumulation in the muscle and liver of the Harpadon nehereus. Water and sediment samples were collected in the three locations and fish sample in one location surrounding the Tarakan Island in September 2010. All samples were extracted using a soxhlet apparatus, and injected to the gas chromatography-mass spectrometry (GC-MS Shimadzu QP2010, with a detection limit of 0.001 ppb) after being cleaned up for identification. Total PAH concentrations ranged from 6.36-380 ^g/l and 50-136 ng/g in the water and sediment, respectively. Total PAH concentrations in muscle and liver ranged from 605-1067 ng/g and -1679 ng/g, respectively. There was an indication that the Tarakan waters has been contaminated by PHAs which derived from coastal activities, and PHAs accumulated in the body of H. neherus.
