Abstract

Proses fotosintesis pada mikroalga membutuhkan CO2 dan cahaya matahari serta nutrien untuk pertumbuhannya. Kultivasi Scenedesmus sp. pada medium air limbah bertujuan guna mencukupi kebutuhan mikroalga akan nutrien dan mengurangi masukan dari bahan kimia yang terkandung dalam air limbah tersebut ke lingkungan. Kultivasi Scenedesmus sp. dilakukan selama tujuh hari pada medium air limbah industri tanpa penambahan nutrien. Hasil kepadatan tertinggi pada akhir kultivasi diperoleh pada medium air effluent senilai 8,033,333 sel/ml dengan berat kering 4,60 gr. Kultivasi mikroalga tersebut juga dapat menurunkan nilai dari Total Padatan Tersuspensi dan Terlarut serta penurunan kadar dari BOD, COD, Nitrit, Sulfit, Sulfat, besi, Krom, Tembaga, dan Seng. Kultivasi Scenedesmus sp. dapat dilakukan pada medium air limbah tanpa perlu penambahan nutrien.

Abstract

Fragmented and non-fragmented soft corals showed antibacterial activities. Soft corals were gradually extracted using methanol, ethyl acetate, and hexane. Crude extract of the samples was tested its antibacterial activity, Minimun Inhibitory Concentration, toxicity (Brine Shrimp Lethality Test method), and phytochemicals. Overall, the antibacterial activity of crude extract of non-fragmented soft coral Sarcophyton sp. was higher than the crude extract of fragmented soft coral Sarcophyton sp. Crude ethyl acetate extract showed higher antibacterial activities. The ethyl acetate crude extract of non-fragmented soft coral Sarcophyton sp. is able to inhibit all tested bacteria is E. coli, S. aureus, P. aeruginosa and B.cereus, while the ethyl acetate crude extract of fragmented Sarcophyton sp. is unable to inhibit bacteria P. aeruginosa. Minimum inhibitory concentration extracts of non-fragmented Sarcophyton sp. in range 240−480 μg/disc. The 24-h LC50 extracts of fragmented and non-fragmented Sarcophyton sp. for Artemia salina were 149.50 ppm and 45.15 ppm, respectively. Bioactive compounds of fragmented and non-fragmented Sarcophyton sp. extract are steroid, flavonoid and alkaloid.

Abstract

Seagrass is one of productive and economical marine ecosystem, but recently there are indications that this area is decreasing and every kind of damage is happening. The research was conducted to reveal the change of seagrass width area and to determine the suitable location for donor and acceptor of seagrass transplantation. Methods of research were collecting and analyzing the satellite image of the research location, bathymetri mapping and water quality parameter, and also determining environment charasteristics that suitable to be performed by counting Seagrass Transplantation Suitability Index (STSI). The results show that in year 1999-2004, the derivation area of seagrass was 678.300 m2. Pari island has depth range between 0-50 metres and the physics and chemical parameter of water have a good range where the seagrass can live. According to the analysis result of STSI, suitable areas for seagrass transplantation donor is station no. 5 and 6 for seagrass species of Enhalus acoroides and station no. 2 and 7 for seagrass species Thalassia hemprichii. The implication of this research is that the seagrass needs rehabilitation to overcome seagrass ecosystem for better condition.

Abstract

The purpose of this research was to study spawning period of sponge Aaptos aaptosat Pari Island, Thousand Islands, DKI Jakarta. The result showed that spawningtime occurred at 17.00-18.00, and within that time the sponge closed their osculumto throw out the zygote leaving the body faster. The duration of spawning rangefrom 4 minutes to 41 minutes. Based on the lunar periode, spawning for spongeAaptos aaptos started from early new moon till few days after full moon. Spawningmostly took place during spring tides. Based on the PCA analysis, it was found thatwater temperature and pressure had strong correlation with spawning time.
