Abstract

Lake Ranau is the second largest lake on Sumatra Island. This lake has a high potency for fisheries. Fisheries activities carried out in Lake Ranau are fishing and aquaculture activities with nile tilapia (Oreochromis niloticus) as the main commodity. Intensive fish farming activities will cause impacts in the form of waste caused by feces and wasted feed. This waste will increase the nutrient loads that enter the waters, triggering the nutrient enriching phenomenon known as eutrophication. Eutrophication is a process of water enrichment by nutrients, mainly nitrogen and phosphorus, which can change the community structure of phytoplankton in the waters and increase their growth. This study aims to analyze the composition of phytoplankton in the waters of Lake Ranau and to estimate the status of water fertility. Data collected was water quality data and phytoplankton data. Status of water fertility was analyzed using the saprobic index. The results show that the community structure of phytoplankton exhibits values as follows: the diversity index ranging from 1.54–3.08, the uniformity index ranging from 0.46–0.90, and dominance index ranging from 0.06–0.41. The abundance of phytoplankton is dominated by the species Nitzhia sp., Synedra, Diatoma, and Tabellaria (all are from the Bacillariophyceae class). The saprobic index obtained ranges from 0.74–1.26, thus categorized as the ?/?-mesosaprobic phase, meaning the waters of Lake Ranau are lightly polluted by a little load of organic and inorganic matters.

Abstract

Pollution caused by increasing industrial activities, particularly dye pollution in water bodies, has posed significant challenges for researchers. As a result, researchers have continued to prioritize the elimination of dyes, motivated by the necessity to protect water quality and reduce the accompanying hazards. Addressing this issue has prompted various approaches, with adsorbents emerging as a promising solution. Among these adsorbents, Poly(amidoamine) (PAMAM) has shown substantial potential in the field of dye removal. This article undertook a review of published articles in this relevant domain and conducted a bibliometric analysis. A total of 36 articles were identified up to the year 2022 and various PAMAM derivatives and the dyes they removed were cataloged. The comparative analysis encompassed articles, authors, journals and countries, highlighting the importance of the research in this area. Furthermore, the article established relationships through co-citation analysis, shedding light on the interconnectedness of research in the field. To visually represent the data, VOSviewer software was employed to create maps, making the findings more accessible and comprehensible.

Abstract

Siombak Lake is one of the tropical coastal lakes in Indonesia, which is unique and distinctive because it is directly influenced by the tidal dynamics of the Malacca Strait (7 km away) through the Belawan estuary. Therefore, Lake Siombak is brackish in its extensive pool. This lake functions as a water catchment, fishing area, and recreation area. This research aims to determine the fertility level and fisheries potential of Lake Siombak waters. The research was conducted from September 2018 to August 2019, but chlorophyll data was only taken for 4 months, namely November 2018, February, June, and August 2019. Water samples were taken during high tide and low tide conditions. Data taken to determine water fertility includes water brightness, phosphate concentration, and chlorophyll a. The fertility of lake waters is determined using various methods, namely the trophic State Index (TSI) method, Trix method, Trophic State Index Lamp (TSI Lamp), and Tropical Level Index (TLI). The brightness of Lake Siombak's waters ranges from 0.6–1.1 m. Phosphate concentrations ranged from 0.05-14.16 mg/L. The chlorophyll content in Siombak Lake ranges from 0.019 – 0.445 mg/m3. The fertility level of Lake Siombak waters is eutrophic-hypereutrophic with a TSI value of 52.0-71.9; Trix index of 2.8-4.9; TSI lamp is 53.7-68.4; and TLI of 4.76-6.32. Spatially, the most fertile lake location is Station 1 (southern region), and temporally the dry season (February) is more fertile than the rainy season (November). The fisheries potential in Lake Siombak ranges from 320 – 773 kg/ha/month. The potential for fisheries production in Lake Siombak is highest in March.

Abstract

Lamongan regency  is one of the areas in the Bengawan Solo watershed always overflow during rainy period and around 50.17 percent of the area was a flood-stricken area called bonorowo. This study aims to identify the composition, species diversity, and potential of fish resources found in the waters of Bonorowo, Kalitengah, Lamongan for 3 months from July to September 2022. The research method is purposive random sampling method. Fish samples were taken using five types of fishing gear, namely gill nets, nets, fishing rods, bubu, and strums. Data was analysed by using relative abundance of each type of fish, frequency of occurrence, the diversity index, evennes index. Also, water quality measurements was done in situ include pH, transparency, temperature, and DO. The results of research showed that there were 16 species which belong to 10 families (Cyprinidae, Channidae, Cichlidae, Claridae, Loricariidae, Belontiidae, Anabantidae, Bagridae, Synbranchidae and Macrobrachium). The structure of the fish community is as follows: the composition of the fish species with the highest percentage of relative abundance is the family Cichlidae represented by species Oreochrosmis mossambicus (18,45%), while catfish (Clarias sp) has the lowest percentage at 1.39%. The diversity index range from 2,493 – 2,540 in the medium category, the evennes index ranges from 0.395 – 0.414 in the medium category, so it is quite uniform, and the all-round dominance index is in the low category for all stations because it ranges from 0.093 to 0.104. For potential analysis, there are two types of fish that have the potential to become ornamental fish, namely Channa striata and Trichogaster trichopterus. As well as the results of measuring water quality parameters prove that the condition of bonorowo waters in Kalitengah sub-regency is good for fish life.

Abstract

Pollution of the aquatic environment can come from domestic, agricultural and industrial activities. The waters of the Teluk Kodek were suspected of being polluted by the activities of waste fuel dumped by ship moorings. This study aims to analyze lead (Pb) contamination in the waters of the Teluk Kodek and to map the distribution of Pb in Turbinaria Sp. This research method is the collection of water samples, substrate and Turbinaria Sp in the waters of the Teluk Kodek with three replications. The heavy metal content of Pb was tested using the Atomic Absorption Spectrophotometer (AAS), and then the data was processed by analysis of variance (ANOVA). At the same time, they are mapping the distribution of Pb in Turbinaria Sp using Scanning Electron Microscopy (SEM). The results showed that the waters of the Teluk Kodek had experienced accumulation of the heavy metal Pb in the substrate samples and Turbinaria Sp. While the results of water samples are still below the threshold. Mapping the distribution of Pb in the Turbinaria Sp sample shows the distribution results in each part of the sample. It is necessary to carry out early pollution prevention activities in the waters of the Teluk Kodek so that the aquatic environment remains sustainable.

Abstract

Climate change is currently a significant issue that poses a threat to the environment. Climate change can trigger increased rainfall, which promotes erosion in many areas. Erosion can lead to the depletion of nutrients in the soil, ultimately reducing the availability of nutrients for plants and causing a decline in land productivity. This can result in widespread land degradation. To avoid this risk soil conservation is needed. Soil conservation can be done to increase land productivity with chemical methods, such as using soil amendments with polyacrylamide (PAM). PAM is an anionic polymer-based material that can improve soil aggregate stability, infiltration rate, and suppress erosion. The purpose of this study is to determine the effect of PAM on erosion suppression, the loss of N nutrients, and on the growth of sweet corn plants. The results of the analysis showed that there is an effect of PAM on the suppression of erosion and loss of N nutrients in the soil. The dose of PAM of 60 kg/ha was able to suppress erosion by 53.16% and reduce the loss of nutrients N by 15.07%. The most optimal and efficient dose in optimizing sweet corn plant growth is 15 kg/ha.

Abstract

Understanding the dynamics of plankton in Kijing Taiwanese (Anodonta woodiana, Lea) cultivation is crucial for optimizing growth performance. This study aims to investigate the influence of stocking density and cultivation methods on the daily population dynamics of plankton in Kijing Taiwanese aquaculture. The experimental study tested different stocking densities in cultivation ponds, namely 5, 10, and 15 ind/m2. Descriptive analysis was employed to interpret the data obtained. The results indicate that Kijing Taiwanese absorb approximately 40 liters/day of water with particle sizes ranging from 0.1 to 5.0 µm, achieving 100% and 99.5% filtration for particles > 4.0 µm and organic matter, respectively. Various class of plankton were identified in the cultivation ponds, including Bacillariophyceae, Chlorophyceae, Cyanophyceae, Dinophyceae, Euglenophyta, and Pyrophyta, with abundances ranging from 2000-68000 ind/cell. The study observed an increase in plankton abundance by approximately 700-2000 ind/cells daily. Water quality measurements revealed pH 7.4, temperature 29.4°C, TDS 92.3 mg/L, turbidity 9-45 NTU, BOD 1-3, DO 5 mg/L, and phosphate (PO4) 0.3 mg/L. This research concludes that there is an influence between kijing stocking density and plankton population density. The interactions that occur are significantly different, because there are significant differences. The higher the distribution density of kijing, the lower the plankton population in the cultivation pond. Further research is recommended to explore the correlation between the abundance of specific plankton types and the growth of Kijing Taiwanese, considering nutrient elements.

Abstract

Challenged by global awareness of environmental problems and demands of the industrial revolution, the Ionic Liquids (ILs) approach as a cheap and environmentally friendly solvent has been explored in various chemical reactions in many industrial fields. This article aims to perform bibliometric analysis of ILs by combining mapping analysis using Publish or Pheris and VOSviewer software and to pinpoint trends in scientific research. For this purpose, an exploratory study with a quantitative approach was developed based on secondary data from journals in google scholar, between 2013 and 2023. The keywords used in the data search are Ionic Liquid, low cost, and green solvent. The bibliometric indicator refers to 1,000 different relevant articles from 52 publishers with the largest number of articles produced by Elsevier, totaling 423 articles. The results showed that the peak of production occurred in 2014 and then decreased every year. The main reason for this increase is the need for cheap and environmentally friendly solvents to replace expensive and environmentally damaging conventional solvents, while the decline is due to the shift of interest into the field of applied chemistry. From the results of the Bibliometric analysis, there are 9 clusters with 126 related terms including low-cost, green solvent, application, study, and extraction. The most popular terms in 2022-2023 are related to fuel terms. This study shows the importance of bibliometric analysis in providing analytical data about what phenomena occur. This research is expected to help and become a reference for researchers in conducting and determining research themes to be taken.
