Abstract

Mangrove has the most important role especially in the coastal area. The existence of mangrove habitats in Banda Aceh which got decreasing and loss after tsunami disaster in 2004. The purpose of this study was to the distribution of mangrove in Banda Aceh divided into five (5) sub districts including Jaya Baru, Kuta Alam, KutaRaja, Meuraxa, and Syiah Kuala. This study the mangrove changes after tsunami 2004, began from 2005, 2010, 2015, and 2022. The main data used in this study are Landsat 5 and Sentinel 2A images. Methods of image processing applied in this study are NDVI analysis and supervised classification-based image classification. Theresults are able to show the changes of mangrove area in Banda Aceh from 2004 to 2022. Mangrove area in 2005 is 28.89 ha, 2010 is 81.38 ha, 2015 is 180.27 ha, and 2022 is 121.34 ha. It can be seen that there is a decreasing of mangrove area from 2015 to 2022. The analysis results are also able to show that Kuta raja sub district has the largest mangrove area of 60.11 ha or 49.54 % of the overall area. According to the overall results, it can be said that remote sensing satellite images such as Landsat and Sentinel 2A are very useful in conducting the spatio-temporal research from the long-term periods. This study is hoped to be able to become a reference data in efforts to restore the mangrove in Banda Aceh in order to create the sustainable ecosystem area.Keywords:Mangrove ecosystemsRestorationNDVISupervised classificationSpatio temporal

Abstract

Kakap River Estuary plays an essential role in the life organisms, but it is vulnerable to environmental changes and pollution caused by human activities. This study aims to assess the presence of plankton species, their abundance and diversity as aquatic ecological bio-indicators in Kakap River Estuary. Plankton and water samples were taken for three months, with a frequency of one sample per month, viz. in March, April and June 2020 from four sampling stations in Kakap River Estuary, West Kalimantan. A total of 34 species of plankton were observed from all sampling sites, and identified to belong to 18 classes. Chlorophyceae had the highest relative abundance among the phytoplanktons (40.10%), followed by Bacillariophyceae (21.86%) and Cyanophyceae (19.28%). Oscillatoria sp. and Hydrodictyon sp. were the most dominant phytoplankton species. There were 8 classes of zooplankton identified from all sampling stations throughout the research period. Hexanauplia had the highest relative abundance among the zooplanktons (36.56%) followed by Euglenophyceae (24.37%). The plankton diversity index (H ′) values ranged between 2.33 -3.11. The plankton evenness index value ranged from 0.79 to 0.89 which indicates high plankton evenness at all samping stations, and this is supported by a low dominance index value at all stations ranging from 0.06-0.16. Station 1 had high Shannon-Wienner diversity index score, while for station 2, 3, 4, their scores were in the moderate level. Overall. the diversity index of the plankton from all sampling sites indicated that the quality of the water had no pollution to light pollution level.Keywords:PhytoplanktonZooplanktonWater quality

Abstract

Abstract. Tilapia is an important fisheries comodity which intesively farmed in Indonesia. However, an intensive farming system of aquatic organism often lead to disease outbreak. Ones the disease emerged, it will be difficult to combat. The curing method by using antibiotics in aquatic organism will bring negative impacts, such as causing bacteria resistance and decline of aquatic environments. Therefore control of disease in aquatic organism should be done through preventive methods such as the use of β-glucan from baker’s yeast (Saccharomyces cerevisiae). It is widely known that yeast’ cell wall contain of immunostimulant substance namely β-glucan. This research was aimed to find the effect of different dose of β-glucan in diet toward the phagocytic activity, respiratory burst which is indicated by Nitroblue Tetrazolium (NBT) activity, total of protein plasm and agglutination activity of tilapia blood. Method used in this study was experiment by complete random design using five treatments triplicate. Those treatments were β-glucan 0; 2,5; 5; 7,5 and 10 ppmkg-1 diet. Result showed that the different dose of β-glucan in diet gave a significantly effect on the phagocytic activity and total of protein plasm, but not on respiratory burst (NBT activity). The highest phagocytic activity occured in treatment E (β-glucan 10 ppmkg-1 diet) with the value of phagocytic activity was 37,67%, whereas the highest of total of protein plasm was occured in treatment B (β-glucan 2,5 ppmkg-1 diet) with the value of 123,58 mgml-1.

Abstract

Chitala lopis, also known as giant featherback, is a fully protected fish species on Indonesian official list due to the susceptibility to exploitation. Several studies showed that the conservation of aquatic resources, such as giant featherback, could be achieved through the implementation of fish farming practices and optimization of feed use. Therefore, this study aimed to determine effect of different feeding rate on growth pattern, performance, and condition factor of the first generation of giant featherback. The first generation of fish was collected from the natural reproduction of broodstock in the earthen ponds. A total of 5 samples were then randomly divided into three treatment groups and reared in the nine net cages installed in the earthen pond. The stocking density in each group was three fish per cage, and the treatments were carried out in triplicates. Feed given comprised fish bycatch as control (T0) (5% of the total weight) and freshwater shrimp, Caridina sp. with two different feeding rates, namely 5% (T1) and 7% (T2) of the total weight. The mean initial weight of all the samples in this study was 41 3.85 g. The results showed that the highest survival and absolute growth rates (29.96.38 g, 78 11%) were obtained in T1, but were not significantly different (p0.05). Furthermore, the highest average relative growth rate was also found in T1 (76.2818.61%) and significantly different compared to other treatments (p0.05). Growth pattern of fish at the beginning of the experiment was negative allometric (0.54), showing a low correlation (0.03), but became positive allometric (4.17) at the end, with moderate correlation (0.66). The results also showed that the highest condition factor was obtained in T2 (0.780.03), and there was a significant effect (p0.05). Based on the results, Caridina sp. had a positive and significant impact on the weight growth of the first generation of giant featherback compared to other studies.Keywords:CultivationFeeding rateGiant featherbackCaridina sp.Rasbora sp.

Abstract

Polycyclic aromatic hydrocarbons are very toxic and persistent environmental contaminants. This study were carried out in Gending watershed Probolinggo in March 2014, the propose of this research was to known  the concentrations and possible sources of 16 PAHs (Polycyclic aromatic hydrocarbons) classified by the United State Environmental Protection Agency as priority pollutants.   Sediment samples were taken by using a sediment sampler at 6 research stations. The concentration of PAH were determined  using Gas Chromatography-Mass Spectrometry (GC-MS)  and the sources using individual ratio diagnose method. The results show that  the concentration of PAHs in  sediment still low and fixed with the safe threshold values for waters organisms. Individual PAH dominated by high molecule weight PAHs. The results of PAHs ratio individual analysis showed that PAHs sources in sediment derived from a variety of sources such as; oil spill, oil combustion and combustion of organic materials. To reduce the level of PAHs pollution in sediment in Gending watersheds need to make efficiency in using of fossil fuel, reduce oil spill and  combustion of oil and organic materials and implementing of laws and sanctions against polluters.
