Abstract

The purpose of this research were to know the ability of polyculture macrophyte (Fimbristylis globulosa and Vetiveria zizanoides) and combination of both with consortium of indigenous denitrifying bacteria from Sutami reservoir that added by Microcystis spp. or not to reduce the concentration of nitrate, dissolved phosphate and the carrying capacity of Microcystis spp. Experiment was done in medium of Sutami reservoir water enriched with 16 ppm of nitrate and 0,4 ppm of phosphate. Denitrifying bacteria were used in this research were DR-14, DU-27-1, DU-30-1, DU-30-2, TA-8 and DU-27-4 isolated from Sutami reservoir. The treatments were incubated during 15 days. Microcystis spp. abundance was calculated every day, but measurement of the the concentration of nitrate and dissolved phosphate were done every six days. The results showed that both treatment and a combination of both macrophytes with a consortium of denitrifying indigenous bacteria were added or not either Microcystis able to reduce nitrate at 99% and 93-99% orthophosphoric. Combination of macrophytes with denitrifying indigenous bacterial consortium from Sutami reservoir was able to inhibit the carrying capacity of Microcystis spp. highest until 47.87%. They can also significantly reduce the abundance of Microcystis from 107 cells/mL in early of treatment to become 0.35x104 cells/mL after fifteen days incubation.

Abstract

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.

Abstract

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

Abstract

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.

Abstract

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.

Abstract

The riparian zone along the Tamiang River, Aceh Province, is an important habitat for the survival of the tuntong laut (Batagur borneoensis) which is already threatened with extinction. This study aims to evaluate the quality and role of the riparian zone as a habitat for B. borneoensis along the Tamiang River, which can then be used as a reference in conservation. Riparian habitat quality was assessed by calculating the Qualitat del Bosc de Ribera (QBR) index, which was determined based on the total riparian cover, cover structure, cover quality, and channel alteration. In addition, observations of water quality (salinity, turbidity, and dissolved oxygen (DO)) and the number of riparian vegetation species were also carried out. Monitoring was carried out at five stations: Iyu River, Kampung Baru, Batang Lawang, Pusong Kapal Dermaga, and Pusong Kapal. The results showed variations in water quality between locations with DO and turbidity levels exceeding the quality standards set by the government. The richness of the types of riparian vegetation found ranged from 0-8 species (seedlings), 2-7 species (saplings), and 1-4 species (poles). The quality of riparian habitats in all study locations experienced significant degradation, including the euhemerobic and polyhemerobic (Hemeroby) categories, Cultural assisted system and Semi-transformed system (Naturalness), and Extreme degradation to poor-fair quality (QBR). The presence of B. borneoensis in the research location can adapt to the poor quality of riparian habitat. However, the density decreases significantly at higher salinity.

Abstract

The study proposed identifying the changes in bacterial community and diversity and exploring the potential correlations among sediments parameters and benthic bacterial communities under different mangrove ecosystems rehabilitation statuses. There were three sites: 1. Banyuurip Mangrove Center (BMC) as a restoration site; 2. Pulau Lusi (PL) as a degraded site; and 3. Kampung Blekok (KB) as natural site. The physicochemical parameters and benthic bacteria from the mangrove sediment of the three locations were observed. The data were analyzed statistically to determine the sites' variation and the correlation between parameters. The results found that the physicochemical parameters among restoration sites varied. Soil organic matter (SOM) in natural and restoration sites was significantly higher than in degraded sites. Cation exchange capacity (CEC), calcium and potassium ions, and soil conductivity of the restoration site were considerably higher than the other sites. According to diversity indices and taxa richness, benthic bacteria in the restoration were the most diverse. Proteobacteria dominated in natural and restoration sites; meanwhile, Firmicutes dominated in degraded site. Sulfurovum aggregans was found abundant in natural and restoration sites; meanwhile, Mesobacillus subterraneus was the dominant species in the degraded site. Furthermore, the bacterial taxa richness was positively correlated with SOM and the bacterial diversity was correlated with CEC and conductivity.

Abstract

Coast is suitable waterbirds habitat, but land use change could negatively influence the waterbirds life. The northern coast of Situbondo Regency, East Java Province, showed variations in land use quality. This study aims to analyze interaction between coastal land use changes on waterbirds diversity and community structure in the coast. Waterbird density was recorded based on the point count along the transect 100 m2 in six stations, namely Kampung Blekok, Tanjung Pecinan, Dubibir, Cemara, Banyuglugur, and Baluran National Park as the reference site. Land use quality in coastal areas was determined by satellites imagery. Habitat preference was determined by neu index. The results showed Tanjung Pecinan and Kampung Blekok stations were favourable waterbirds habitat, dominated by agriculture and low industry areas. These stasions better supported waterbird life and closed characters to Baluran one, where was dominated by mangrove forest and agriculture. This reference site showed highest diversity (H’ 2.26) and evenness (E 0.75), while preference habitat showed lower diversity (H’ 1.39) and evenness (E 0.29). On the contrary, Banyuglugur showed an industrial area, we found a low density species. Baluran and Kampung Blekok were habitat of three IUCN red list species, such as Ciconia episcopus, Charadius javanicus, and Leptoptilos javanicus.
