Aktivitas keramba jaring apung (KJA) dapat mengakibatkan penurunan kualitas air. Tujuan penelitian ini adalah menentukan dampak aktivitas KJA di Waduk Lahor terhadap perubahan Kualitas air berdasarkan beberapa paremeter fisika kimia dan indeks biotik dari Diatom sebagai bioindikator. Pengambilan sampel air dan Diatom dilakukan di muara Sungai Lahor (3 stasiun) merupakan inlet dari Waduk Lahor dan daerah sekitar bendungan (1 stasiun) menggunakan purposive random sampling berdasarkan aktivitas KJA dengan pengulangan pada masing-masing stasiun tiga kali. Pengambilan sampel Diatom dengan water sampler vertikal dan disaring menggunakan plankton net. Identifikasi dan perhitungan Diatom dengan Counting Chamber Sedgewick Rafter Cell dan buku identifikasi. Hasil identifikasi dan penghitungan Diatom digunakan untuk menentukan Trophic Diatom Index (TDI) dan Pollution Tolerant Value (% PTV). Karakter fisika kimia air (pH, kecerahan, turbiditas, DO dan BOD) diukur pada lokasi yang sama dengan pengambilan sampel Diatom. Hasil penelitian menunjukkan bahwa kualitas air terutama parameter BOD dan kecerahan di Waduk Lahor belum memenuhi standar untuk aktivitas perikanan. Aktivitas KJA di muara Sungai Lahor berdasarkan beberapa indek biotik dari Diatom telah berdampak pada penurunan kualitas air yaitu status nutrisi menjadi eutrofik sampai hiper-eutrofik (TDI) dan tingkat pencemaran bahan organik ringan sampai sedang (% PTV).

The main objective of this research was to calculate the carrying capacity and growth rate ofisolated Microcystis result in Sutami reservoir on a variety of nitrate and phosphateconcentrations in the B-12 selective medium. Research was conducted in the laboratory withpure experiments using completely randomized factorial design with factors of nitrateconcentration variation (8, 16, 32, and 64 ppm) and phosphate (0.2, 0.4, 0.8 and 1.6 ppm) in B-12medium. Repetition of the study was conducted three times at the same time. Microcystispopulation abundance which was counted every day until the stationary phase (day +30) wasused to calculate the rate of growth (Î²) and maximum abundance of Microcystis can besupported by each medium treatment (Î³). The results showed that the growth rate of Microcystiswas not significantly influenced by levels of phosphate in the medium but significantly positivelycorrelated with increasing nitrate concentration in the medium. Carrying capacity or themaximum abundance (Î³) of Microcystis was influenced by the combination of nitrate andphosphate in the B12 medium. Concentration of phosphate 0.4 ppm in medium combined withnitrate 8âˆ’64 ppm could support the highest abundance of Microcystis.

Publisher : Journal of Tropical Life Science

Diatoms or phytobenthic are often used as bio-indicators of water quality in freshwater ecosystems such as rivers, but have never been used for monitoring the quality of artificial water ecosystems. The objective of this research is to use the diatom as a bioindicator for measurement the success of phytoremediation process of irrigation water that has status hyper-eutrophic and is polluted from organic materials using polyculture of various local hydromacrophytes through batch culture system. This experimental study was conducted in a greenhouse through planting some local emergent, submerged and floating leaf hydromacrophytes on a 30 L bucket with a given substrate from sand and gravel. The experiment used a completely randomized design with two treatment included phytoremediation model and control in the form of substrate without hydromacrophyte which repeated three times at the same time. The success of phytoremediation model was determined through some biotic diatoms indices (Percentage Pollution Tolerant Value/%PTV, Tropical Diatom Index/TDI and Shannon Wiener Diversity Index) as bioindicator and the improved water physics chemical quality on days 0, six, and 13 after incubation. The results showed that phytoremediation process using polyculture hydromacrophytes through batch culture system for 13 days significantly improving the quality of irrigation water. Based on some biotic diatom indices, the water was improved from heavily organic pollution to moderately organic pollution (%PTV), from hypereutrophic to become eutrophic (TDI) and from moderately polluted become slightly polluted (Shannon Wiener Diversity Index). This results also supported from water physico-chemical parameters. Poly-culture of some local hydromacrophytes for six days significantly decreased the organic matter content of irrigation water was reflected from the decrease concentration of Biochemical Oxygen Demand/BOD (14.79 mg/L to 3.61 mg/L), Total Suspended Solid/TSS (14.6 mg/L to 0.08 mg/L), turbidity (19.97 NTU to 1.46 NTU), nitrate (1.44 mg/L to 0.03 mg/L), orthophosphate (0.24 mg/L to 0.042 mg/L), Total Kjeldahl Nitrogen (TKN) (0.93 mg/L to 0.68 mg/L), and free chlorine (0.09 mg/L to 0.05 mg/L), while concentration of Chemical Oxygen Demand (COD) decreased significantly 13 days after incubation from 48.3 mg/L to18.2 mg/L.

ABSTRACTIrrigation water in Indonesia generally has polluted by organic matter due to human activities. The aim of study was to develop a package of phytoremediation technology that can effectively reduce organic pollutants in the irrigation water in order to ensure good quality of water irrigation to support organic farming. The study was conducted in greenhouses by planting some local emergent, submerged, floating-leaf hydromacrophytes and polyculture species using a batch culture system on a 30 L bucket with sand and gravel as a substrate. The study used a completely randomized design with the treatment were five types of hydromacrophytes (emergent such as Scirpus sp., Acorus calamus, Marsilea crenata; floating leaf macrophytes included Ipomoea aquatica, Azolla sp.; submerged such as Valisneria sp., Hydrilla verticilata; polyculture of the three hydromacrophytes, and controls without plant) which repeated three times at the same time. The effectiveness of the phytoremediation model for each treatment is determined by its ability to improve water quality as reflected by several physicochemical parameters of pH, DO, conductivity, turbidity, temperature, nitrate, orthophosphate, bicarbonate, BOD, TSS, TDS and TOM six days after incubation. Research results showed that batch culture for six days significantly reduced the organic matter content of irrigation water reflected from decreasing value of BOD, TOM, TSS, turbidity, nitrate, orthophosphate and bicarbonate levels. The six-day phytoremediation process in all treatments has not been able to increase the dissolved oxygen content in the water and has not been able to significantly reduce the conductivity and TDS. Hydromacrophytes submerged and polyculture were more effectively perform phytoremediation process compared with others.Keywords: Phytoremediation, local hydromacrophytes of emergent, submerged, and floating leaves, water pollution

Publisher : Journal of Tropical Life Science

The quality of water in Spermonde Archipelago, South Sulawesi has decreased as a result of high human activities and land use, this can have an impact on the life of marine biota. Macroalgae is suitable for bioindicators because they live in a sessile manner, can accumulate metals and distributed widely. This research aimed to determine coastal ecosystem quality by using macroalgae as indicators on five islands that had different anthropogenic stresses. The research was carried out in April 2019 on Barrang Caddi, Bonebatang, Barrang Lompo, Kodingareng Keke, and Badi Islands. Community structures observed included taxa richness, diversity, evenness, dominance of macroalgae and physicochemical parameters (temperature, turbidity, pH, salinity, DO, BOD, H2S, oil, grease, total Phosphate, and nitrate) as well as the measurement of the ecological condition using Quality of Rocky Bottoms (CFR) index. The results showed that physicochemical parameters (temperature, turbidity, pH, salinity, DO, H2S, oil, grease, total Phosphate) of the water still met the quality standards of sea water based on Decree of the State Minister for Environment No. 51/2004 for marine biota and other standards for macroalgae growth. BOD and nitrate have exceeded sea water quality standards for marine biota (20 mg/L for BOD and 0.008 mg/L for nitrates). A total of nine species of macroalgae were found in Barrang Caddi and Badi Island, three species in Bonebatang, and five species in Kodingareng Keke and Barrang Lompo Island. The result of Principal Component Analysis (PCA) and Biplot showed that physicochemical water quality has an influence on the macroalgae community structure. While the CFR index shows Barrang Caddi and Badi Island have poor ecological conditions and Bonebatang, Barrang Lompo, and Kodingareng Keke have bad ecological condition.

Daphnia (water fleas) belong to the zooplankton group called Cladocerans have sexual reproduction when conditions less favorable that produce diapausing eggs are enclosed in the ephippium. Hatching ephippial eggs in the laboratory is important in ecological, toxicology, genetical, and evolutionary studies. This study aims to improve the current methods of egg hatching from ephippium. Each of 50 ephippium were treated together by placing them in a glass jar and adding 50 mL bleach solution (sodium hypochlorite). Concentrations of sodium hypochlorite used in this experiment were 0%, 0.5%, 1%, 2%, 4% and 8%. These concentration treatments were crossed with the following exposure times (1, 2, 4, 8, 16, and 32 minutes). Culturing was done in 80 mL of artificial Daphnia medium, incubated in constant light and temperatures 20Â°C for 25 days. There were two repetitions in this experiment that were run at the same time. Result of this experiment showed that pretreatment with 0.5-8% bleach solution significantly increases the yield of total hatch rate of Daphnia magna resting eggs by about 21% over unbleached control. However, there was no significant difference among the bleach treatments. Concentration of bleach solution 0.5%, 1% and 4% significantly accelerated the time period until the first hatching (first day hatching). Difference of exposure time (1 - 32 minutes) at each concentration treatments were not influence the yield of total hatch and the time period until first hatching.

Microalgae Cyanobacteria from the genus Microcystis has the potential to bloom in Sutami reservoirs that located in Malang, Indonesia at a particular time. Microcystis is a notorious species because it can produce toxins that are dangerous to other organisms. The objective of this research is to determine the influence of different ratios of Nitrate and Phosphate on the growth of Microcystis in Sutami reservoir. The study was conducted from April to November 2009 and was carried out in situ in the reservoir Sutami with quasi experiment using a completely randomized design. Sutami reservoir water which already contained plankton community therein, including Microcystis were treated with five variations ratio of Nitrate and Phosphate (10, 20, 40, 80, and 160) and untreated water as control. Experiments carried out by using a transparent plastic bag diameter 1 m and 1.5 m long, inserted into the water and be immersed in the water by using bamboo. Calculation of Microcystis abundance and physic-chemical quality of water is done every three days for a month. The results showed that the higher concentration of orthophosphate in the media water of Sutami reservoir have the maximum abundance of Microcystis. Abundance of Microcystis grown in Sutami reservoirs have positively correlated with actual levels of nitrate, nitrite, total phosphate, conductivity, pH, temperature, ratio of Nitrate to Phosphate treatment and water KMnO4 value.Keywords: Blooming Microcystis, the ratio of nutrients Nitrate to Phosphate, Sutami reservoir

The aim of this study is to find out the kind of hydromacrophyte composition having the highest capability to reduce nitrate-phosphate pollutant and Microcystis growth in phytoremediation media using Equisetum ramosissium, Typha angustifolia and the combination of both. Microcystis were obtained from Sutami reservoir, then being inoculated in a media grown by hydromacrophytes (E. ramosissium, T. angustifolia and both of the hydromacrophytes) in the batch culture system. The number of Microcystis was counted every day within fifteen days. Abiotic factors were observe, including the concentration of nitrate using brucine-colorimetry method and orthophosphate (dissolved phosphate) using stannous chloride-colorimetry method on day 0, 6th, 12th and 15th. The growth rate of Microcystis carrying capacity and orthophosphate-nitrate levels among treatments were analysed by ANOVA test. The results showed that E. ramosissium and T. angustifolia in mono and polyculture techniques had similar potentiality to reduce the nitrate and ortophosphate. The concentrations of nitrate and orthophosphate decreased over 70 % in the 6th day after incubation. All of the treatments were able to reduce the carrying capacity of Microcystis up to 46 % , but the growth rates were similar in all media, that is, around 97-170 cells/L/day. Keywords: Equisetum ramosissium, Microcystis, nitrate, phosphate, Typha angustifolia

The aim of this research was to know the effect of anthropogenic activity around the coastal Giliketapang Island to community structure of coral reef. This research used belt transect method which consist of 18 transects in three location (harbour,near the forest and transition areas)at 50-80 m from the coast, with plot size of 2x2m2. Abundance of coral reefs were observed base on the coverage. There are found 11 families of coral reefs. The percentage of coral damage was decrease and the number of species was increase at the far zone from coast. This is also affect the coverage value of coral reefs. Coral coverage at the harbour and near the forest was 53. 06 % and 65. 36 % respectively, whereas in the transition area was 38. 38%. Co-domination between Porites lobata and Chyphastrea microphthalma occurred at the harbour, while Porites mayeri and Acropora spp. co-dominate in near the forest location. Poritidae family dominate in the transition area. Anthropogenic activities at transition location cause severed damage of coral reefs.
