Abstract

The objectives of this study are (1) Determine the content of antrasena compound in the waste oil at the waterway of Paotere port (2) Determine the characteristics of antrasena degradation bacteria and (3) Determine the percentage of antrasena degradation. In this research an analysis of antrasena compound was conducted with sea water that had been polluted with oil. The next steps were to isolate and characterize the degrading bacteria of antrasena and to analyze the results of antrasena degradation. The results showed that (1) Concentration of the antrasena compound in the waterway of paotere port is 4,8x10-10 ppm. (2) The bacteria can degraded of the antracene is Bacillus cereus (3) There was evidence that Bacillus cereus was able to degrade antracenr compound, the highest degradation percentage is 98,11%, it was achieved on 12 day of incubation

Abstract

Algae is a plant which life in the marine with a lot of diversification such as: single and multi-cellular. Commonly, it contains chlorophyll without stem and roots. A species of algae in Indonesia which has high economic value is Eucheuma cottoni. It is cultured in Bantaeng as the central production of algae in South Sulawesi. The aim of this research is to know the concentration of heavy metals Cadmium in algae at region Bantaeng coastal. Concentration of cadmium was determined by atomic absorption spectrophotometer (AAS). This analysis was done by destruction process using concentrated HNO3. Sampling was done at 6 different location, they are: Nipa-nipa, Bakara, Boroloe, Tapaloe, Baruga village and Baruga from north to south. The experiment result show that the highest concentration of Cd is in Nipa-nipa village, with 0.2920 ppm and the lowest in Baruga village is 0.1824 ppm. The concentration of Cd in algae Eucheuma cottoni in those 6 different location had been more than limited which had been determined by the decision of national of environmental ministry number 51 year 2004, they are 0.01 and 0.05 ppm.

Abstract

The compounds pyrene is one of the polycyclic aromatic hydrocarbons (HAP) which is derived from petroleum. These compounds are carcinogenic and toxic for the marine biota. The purpose of this study to determine the levels of pyrene compounds in marine algae. In this research, analysis of pyrene compounds in marine algae Eucheuma cottonii using the method of GC - MS (Gas Chromatography - Mass spectrophotometry). Sampling was conducted in the waters the Bantaeng Regency with a 6 point sampling different locations namely Nipa-nipa, Bakara, Boroloe, Tapaloe, Baruga village and Baruga. The results showed that the concentration of pyrene compounds found in marine algae Eucheuma cottonii at 6 locations in waters the Bantaeng Regency has a concentration low enough pyrene compounds that is 0009-0063 ppm. This means that the concentration of pyrene was obtained below the threshold value determined by the decision of national of Environmental ministry for the marine life.

Abstract

Research on phytoaccumulation of Ni and Zn in Nypa fruticans plants at Tallo River has been done to know the capability of Nypa fruticans for accumulating Ni and Zn. Water, sediment, and plant tissue samples were taken at five stations on the Tallo River using a cutting tool and pipe paralon. Sediment was digested with concentrated HNO3 while plants tissue using HNO3 6M, then analyzed by ICP EOS Shimadzu 9000. The results showed the average concentration of Ni inside part of the plant from station 1, 2, 3, 4 and 5 in order following 21.759,03 ppm, 19.056,03 ppm; 36.806,25 ppm; 10.736,66 ppm dan 13.849,25 ppm. Average concentration of Zn inside the plant from station 1, 2, 3, 4 and 5 in order following 1.319,60 ppm; 1.362,93 ppm; 2.053,46 ppm; 1.591,60 ppm; dan 1.474,09 ppm. Accumulation of Zn and Ni in Nypa fruticans is grouped as hyperaccumulation plant because the ability of accumulation Ni bigger than 10.000 mg/kg and hyperaccumulation towards Zn because able to accumulate Zn bigger than 10 mg/kg. BCF and TF value show that Nypa fruticans naturally able to be used as an phytoremediation plant towards Ni and Zn, especially phytoextraction and rhizofiltration.

Abstract

Mesoporous silica SBA-15 is an interesting material having highly ordered nanopores and large surface area, which is synthesized by sol gel and hydrothermal methods. In this study, mesoporous silica SBA-15 was synthesised with two different methods and the characteris was using X-Ray Diffraction (XRD) and Differential Scanning Calorimetry (DSC). SBA-15 was prepared TEOS as precursor and Pluronic 123 as surfactant. Thermoporous mesoporous DSC thermogram results of the SBA-15A mesoporous silica is (Tg 79oC and Tc 158oC). This is relatively lower than SBA-15B (Tg 86oC and Tc 158oC). The measurement of low angle X-Ray Diffraction SBA-15A has a crystal size 9.46 nm and SBA-15B has a crystal size 9.96 nm. The synthesis of SBA-15 using the hydrothermal method needs to be studied further to obtain thermal characteristics and a more stable crystal structure
