The objectives of the study are to describe the iron content of seagrass area ecosystem and its relation with nature of physico-chemical territorial water. The sampling of seagrass was conducted in purposive sampling technique for every status of the field and performed in three spots of the seagrass ecosystem region with reference to the depth of water and the current direction. Based on statistical tests of factorial and variance analysis indicate that the quality of physico-chemical territorial water in the coastal region of Donggala regency still very good, relatively. The result also showed, The Demand Oxygen and the turbidity gave a positive effect to Fe- seagrass improvement in its various association. Besides, the limiting factor for the low of Fe-seagrass is the height of salinity and water temperature. If the results were combined with another micro and macro mineral analysis will to become the basic for estimating the status of seagrass fertility.

Air Asam Tambang (AAT) dapat ditanggulangi dengan menggunakan sedimen sebagai sumber inokulum mikroba dalam mereduksi sulfat. Penelitian ini bertujuan untuk mengetahui pengaruh sedimen rawa dan sawah dalam peningkatan pH, penurunan kadar sufat dan jumlah mikroba pada air asam tambang. Perubahan pH diukur dengan menggunakan pH meter, kadar sulfat diukur dengan metode titrasi dan total mikroba dihitung dengan metode SPC (standar plate count). Hasil penelitian menunjukkan bahwa pemberian sedimen pada AAT dapat meningkatkan pH AAT dari 3 menjadi 6,263 pada sedimen rawa dan menjadi pH 6,557 setelah 30 hari. Pemberian sedimen juga mampu menurunkan kadar sulfat dari 563,15 ppm menjadi 327,41 ppm pada sedimen rawa dan menjadi 237,44 ppm pada hari ke-30. Penelitian ini juga menunjukkan bahwa jumlah mikroba pada sedimen rawa meningkat dari 2x105 sel/ml menjadi 37X105 sel/ml dan pada sedimen sawah juga meningkat dari 4,3X105 sel/ml menjadi 86X105 sel/ml pada hari ke-20.Kata Kunci: Sedimen, Air Asam Tambang, Bakteri Pereduksi Sulfat

The use of epichlorohydrin to improve the stability of chitosan adsorbent has been carried out. The purpose of this study was to determine the stability of the chitosan adsorbent after modified into epichlorohydrin cross-linked chitosan and ionic cobalt imprinted adsorbent chitosan cross-linked epichlorohydrin. Adsorbent prepared by homogeneous gel formation of chitosan in acetic acid medium and then modified into epichlorohydrin cross-linked chitosan beads and ionic cobalt imprinted adsorbent chitosan cross-linked epichlorohydrin. Stability of the adsorbent was determined by calculating the percentage of insoluble material after stirring the adsorbent in nitric acid medium at pH 1, 2, and 3 for 12 hours. The results of FTIR spectra show a shift of the absorption band of chitosan were compared with epichlorohydrin cross-linked chitosan and ionic cobalt imprinted adsorbent chitosan cross-linked epichlorohydrin. The use of epichlorohydrin as cross-linked agent may increase the stability of the adsorbent to maintain the percentage of insoluble material by 89% at pH 3 for epichlorohydrin cross-linked chitosan adsorbent and 96% at pH 3 for ionic cobalt imprinted adsorbent chitosan cross- linked epichlorohydrin.

Cellulase enzymes can be isolated from microorganisms that are resistant to high pH and temperature. Cellulase enzyme has a different character depending on the source and the enzyme environment. This study aimed to characterize the cellulase enzymes from bacteria isolates CC2 dan CC4 which includes the determination of the optimum pH and temperature of the enzyme activity. In this study, an enzyme produced from isolates of bacteria larva Cossus cossus by centrifugation cold 4 ° C with a speed of 3000 rpm for 15 min to obtain a crude extract of the enzyme cellulase.

Paotere port is one of port in Makassar which functions as a stopover place of ships, also serves as fish market and fishermen settlements. Various activities of transportation, commerce and households occurred in the Paotere port area can be a source of pollution of pyrene compounds to the surrounding environment. Pyrene compounds that accumulate and can not be degrade will impact the environment and marine life. Determination pyrene in sediment from Paotere Port have been carried out using GC-MS by sonication using dichloromethane as solvent. Result show that there was no PAH in sediment of the three sampling stations. Pyrene compound chemically degradation was conducted by sonication for 1 hour using an oxidant KMnO4 concentration of 0.05 M, 0.07 M and 0.1 M. Results show that KMnO4 as oxidizing agent could to degrade the whole pyrene with concentration of 87,8554 ng/g in sediment.

The toxicity of petroleum sludge is a serious threat to marine life. Necessary concrete stepspetroleum contamination reduction through a search of potential marine materials degradetoxic components hydrocarbons. The sponge is one potential material reducing toxicproperties of petroleum contamination. The research objective was to determine thepotential Callyspongia sp sponge against the degradation of petroleum hydrocarbonsludge. Four variations of treatment used to determine the potential of sponge biomass,namely: the treatment I, II, III and IV. Indicators degradation is the formation of gas, thesmell fermentation, pH changes and increase in the absorbance of the suspension of mediadegradation. The level degradation each treatment is determined gravimetric method andthe known hydrocarbon component changes by using GC-MS. Unidentified gas, the smellof fermentation and changes in media of pH on average degradation occurs on the 15 daysof contact for all treatments. Data showed degradation occurs absorbance maximum at 20-25 days to contact. The highest degradation rates indicated by IV treatment (26.93 %), III(24.84 %), II (22.59 %), and I: (18.20 %). Found 20 kinds of components in the wastesludge aliphatic petroleum to form a homologous series nC10-nC30, and two aromaticcomponents, namely the 2.7-dimethyl naphthalene and 1.4-dimethyl azulene. Callyspongiasp sponge biomass concluded at the highest IV treatment degrading aliphatichydrocarbons, then treatment III, II and I, while the aromatic components are not degradedby biomass Callyspongia sp sponge at all treatments.
