Abstract

This study aims to compare the biodiversity of ichthyofauna in seagrass meadows between the day and night periods. The study was conducted in July 2019 on seagrass habitats in the coastal waters of Wamsisi village, Buru Island, Maluku. Fish samples were collected using battom gill nets placed on seagrass meadows during the day and night periods. Data analysis includes species composition, community structure (dominance index, diversity, and uniformity), frequency of presence, and grouping similarity of fish species using the Bray-Curtis Index, which is displayed in the form of tables and dendrograms. The results obtained as many as 72 individuals, 34 species from 14 families, and 4 orders. The species composition and the highest frequency of presence were Naso hexacanthus (Acanthuridae) during the day, Caesio caerulaurea (Caesionidae), and Lutjanus gibbus (Lutjanidae) at night, diversity and equitability indexes were in the high category, whereas the dominance index was in a low category. Based on the life phase, the ichthyofauna was dominated by the pre-adult of 17 species (50,0%), adult of 12 species (35,3%), and yuwana phase of 5 species (14.7%). The similarity of species between the day and night periods is categorized as low in value, which means the presence of fish species is different between the day and night periods.

Abstract

Tilapia is one type of freshwater fish that has a lot of demand in the market. Therefore, the production of tilapia aquaculture is increasing. Increased production of aquaculture causes a decrease in water quality due to the large number of metabolic wastes. Fish farmers usually require a large amount of money to overcome the decline in the quality of aquaculture pond water. For this reason, it is necessary to apply techniques to improve the quality of aquaculture pond water at an affordable cost. Azolla sp and Ipoemea aquatica are plants that can absorb environmental contaminants. The research method used was experimental method with untreated pool water samples (control), pool water samples treated with kale (Treatment 1), pool water samples treated with Azolla sp. (Treatment 2) and pond water samples with the combination treatment of kale and Azolla sp. (Treatment 3). Ammonia levels in Tilapia pond water samples were statistically analyzed using the SPSS application. The results showed that kale and Azolla sp. tends to be effective in reducing ammonia levels in Tilapia rearing pond water. The water spinach treatment had a higher value in reducing ammonia levels in the sample water of the tilapia rearing pond, which was 5.99 compared to the Azolla sp. of 3.22 and the combination treatment of 5.95.

Abstract

Supit Urang Fecal Waste Treatment Plant (IPLT) is a facility provided in overcoming sanitation problems, the Supit Urang STP in addition to accommodating also treats fecal waste before being discharged into the river. In an effort to maximize the utilization of river water, it is necessary to monitor water according to quality standards. Water purification can be through filtration, adsorption, sedimentation, ion exchange and microbial processes using aquatic plants in wetland ponds. This study was conducted using observational descriptive by taking samples at the inlet, midpoint and outlet point. Sample testing was carried out at UNISMA Integrated Laboratory and Halal Center. The parameters observed are temperature, TDS, TSS Conductivity and turbidity. Then the value obtained from the observation will be compared with the quality standards set by the government. The effectiveness of the phytoremediation process using Indian Shot (Canna indica) is significantly able to reduce temperature, TDS, conductivity and turbidity parameters. In the TSS parameter, there was also a decrease even though the TSS value still exceeded the quality standard. The decrease and increase of the observed parameters is due to several factors both organic and inorganic factors of the waters. So this affects the phytoremediation process. The Constructed wetland method using Indian Shot (Canna indica) shows that all parameters decrease when the adsorption process by plant roots

Abstract

Phytoplankton has been known to play its role as an indicator of water quality. In the intensive cultivation system of Pacific White Shrimp (Litopenaeus vannamei), phytoplankton can respond to water quality dynamics simultaneously. However, the impact of weather differences on community structure and phytoplankton diversity has not been further investigated. Here we analyze water quality and phytoplankton diversity in ponds, including uniformity and dominance. The results showed that 12 genera of phytoplankton were found in sunny weather, whereas 9 genera were found in rainy weather. Phytoplankton diversity in sunny weather is greater. The diversity index (H') value when it rains and shines is in the medium category with a stable community structure and low polluted water conditions. The uniformity value (E') is moderate. No plankton dominance was found (C ≤ 0.5) with the highest important index value during rain being Rhizosolenia sp. and Chlorella sp. when it's sunny. Water quality in general does not differ and meets quality standards except for the nitrate and phosphate values. Nitrate and phosphate values in both weather conditions exceeded standard standards. Differences in the types of phytoplankton present in different weather can be caused by the brightness that enters the water. Apart from that, the volume of water and the dilution and mixing effect of rainwater can cause differences in the amount. The source of growth nutrients is a supporting factor for phytoplankton growth.

Abstract

Pre-harvest fish mortality was often found in polyculture vannamei shrimp and milkfish in Duduksampeyan. This is thought to be caused by declining water quality. This study aims to evaluate water quality based on physico-chemical parameters and biotic index in vannamei shrimp (Litopenaeus vannamei) and milkfish (Chanos chanos) ponds. The study was carried out in February-March 2021 in Duduksampeyan using a purposive sampling method from 3 stations, vannamei shrimp ponds (station 1), milkfish ponds (station 2) and polyculture ponds (station 3) at 3 sampling points located at the inlet/outlet, middle and edge. Data analysis using ANOVA followed Tukey's test to compare data from the three stations. Correlation analysis, PCA and cluster to determine the relationship between environmental parameters and plankton. The physico-chemical parameter values were in accordance with SNI8037.1:2014 except for salinity, suspended solids at the three stations, brightness at station 3, dissolved solids at station 2. Station 1 found 8 classes with 17 genera, station 2 contained 8 classes with 11 genera and stations 3 there are 7 classes with 14 genera. The most common genera found at station 1 were Synechocystis, Spirulina, station 2 Synechocystis, Pandornia, Chaetoceros, station 3 Synechocystis, Pandornia, Spirulina. The diversity index value is between 1.7-3.1ind/L. Human activities such as settlements, livestock and agriculture are thought to be the cause of the decline in water quality from being eutrophic to hypereutrophic (TDI). The relationship between plankton and environmental parameters shows that at station 3 the optimum results are obtained to support the life of aquatic biota.Keywords: Physics-Chemistry, Diversity Index, Water Quality, PlanktonABSTRAKKematian ikan pra panen banyak dijumpai pada tambak budidaya polikultur udang vannamei dan ikan bandeng di Kecamatan Duduksampeyan.
