Abstract

Biodiversity of Cyanobacteria from several ponds/lakes of Jakarta-Depok-Bogor, Indonesia. Research about the exploration on Cyanobacteria diversity from several ponds/lakes of Jakarta-Depok-Bogor area was done. Five research locations were Sunter 2 Lake of North Jakarta, Babakan Pond of South Jakarta, Ulin-Salam dan Agathis Pond at UI Campus of Depok, dan Lido Lake of Bogor. Samples were taken by purposive sampling, and samples analysis using subsample methode. The sampling times were on August to September 2006. Three types of samples which were taken were planktonic samples, epifitic samples, and waters bank soil samples. The results showed that several toxic potential Cyanobacteria were found in several waters, even they were dominant at Sunter 2 Lake dan Agathis Pond (UI Campuss). Based on similarity levels of Cyanobacteria, the five of waters could be classied into 3 group, i.e. Sunter 2 Lake and Agathis Pond, Babakan dan Ulin-Salam Pond, dan Lido Lake. Lido Lake waters was very unique on distribution and diversity of Cyanobacteria. Based on diversity Index (H’) of Cyanobacteria, several waters condition could be catagories as moderate waters, i.e. Babakan, Situ Ulin-Salam, and Situ Agathis Pond. The epifitic and waters bank soil Cyanobacteria which were found were also found as planktonik species except Oscillatoria sp. 3. At least 26 isolate of Cyanobacteria were acquired such as Miicrocystis, Oscillatoria, Gloeocapsa, Merismopedia, Planktothrix, dan Arthrospira.

Abstract

The effect of Tauge Extract Medium (TEM) concentration to the growth of Subang isolated Scenedesmus. Research on the effect of several concentration of Tauge Extract Medium (TEM) to Scenedesmus Meyen cell densities was conducted. The research was an experimental study with complete random design with 8 treatments, i.e. 1%, 2%, 3%, 4%, 5%, 6% TEM, aqua bides, and Bold Basal Medium (BBM). The results showed that TEM concentration effected cell densities of Scenedesmus. At peak condition, the highest cell density (3.981.071 sel/mL) was occurred in 4% at the day of seven, and the lowest cell density (87.096 sel/mL) in aqua bides at the day of three. Kruskal-Wallis test showed that there were differences between the mean of cell densities on all treatment media. Multiple comparison test showed that mean of cell numbers of Scenedesmus differed among treatments (p value>0,05) between aqua bides with 1%, 2%, 3%, 4%, 5%, 6%, and BBM.

Abstract

The Growth of Chlorella spp. in Tauge Extract Medium (TEM) with Various Initial pH. Research on the effect of tauge extract medium initial pH value on Chlorella Beijerinck cell densities at peak condition had been done. The research was an experimental study with complete random design with 5 treatments (tauge extract medium with initial pH 5,6,7,8, and 9). At peak condition the highest cell density (5.677.625 sel/ml) was occured in medium with initial pH 7 and the lowest (3.374.100 sel/ml) in medium with initial pH 5. Anova test shown that there was an effect (p value>0,05) of tauge extract medium initial pH value on Chlorella cell densities (cell/ml) at peak condition. Multiple comparison test showed that mean of cell numbers of Chlorella differed among treatments (p value>0,05) except between media with initial pH 8 and 9.
