Abstract

Microplastics (MPs) refer to plastic waste particles that measure less than 5 millimeters in size. Their presence is widespread in the environment, particularly in aquatic ecosystems, posing significant risks to coastal organisms and human health. This study aims to assess microplastic contamination in the Kombal bay estuary by conducting identification, abundance analysis, and characterization of microplastics. The method used was to characterize the area, sample extraction, observation and calculation of microplastic abundance, FTIR analysis, water quality testing, and data analysis. Originating from the Teluk Kombal river, this estuary is subjected to various human activities such as fishing, agriculture, and household waste disposal. Sampling was conducted at three representative locations: the estuary, agricultural areas, and residential areas within Teluk Kombal, North Lombok, West Nusa Tenggara, Indonesia. Samples were collected and filtered for identification using a microscope Olympus Culture Inverted, 4×100 magnification. The results revealed microplastic abundances ranging from 19.5±14.71 to 25±14.54 particles per liter in water, 9.25±8.54 to 10.75 ±9.53 particles per kilogram in sediment, and 10.25±13.28 to 10.5±10.28 particles per individual in Padina sp. across the three locations. Various types of microplastics, including fragments, films, pellets, and fibers, were identified, with dominant colors of yellow, blue, red, black, and green. The presence of microplastics in the Teluk Kombal estuary and river indicates that they have been contaminated with microplastics, which can cause serious problems for organisms inhabiting them. Therefore, further research is needed to investigate the impact of microplastics on organisms and ecosystems in the estuary.

Abstract

Agricultural activities in the Opak Watershed, especially in the upper part located in Sleman Regency, require special attention because they have the potential to have a negative impact on river water quality. The use of pesticides on agricultural land contributes to polluting river water through rainwater runoff. Runoff containing residual organophosphate pesticide residues will reduce river water quality. In order to prevent pesticide pollution in the Upper Opak Watershed (UOW) in a sustainable manner, effective management is needed. However, the lack of information regarding estimates of pesticide concentrations in runoff in the UOW could hamper the management process. Therefore, it is crucial to estimate pesticide concentrations from agricultural land in the Cangkringan and Pakem Subdistricts contained in runoff in the UOW. Estimation of pesticide concentrations in runoff can be done by conducting hydrological modeling. The Soil Conservation Service-Curve Number (SCS-CN) model is the simplest compared to other models, but this model needs to be combined with the Predicted Environmental Concentrations (PEC) model to be able to estimate pesticide concentrations contained in runoff in the UOW. The research results show that the Cangkringan Subdistrict   is the larger contributor to the concentration of organophosphate pesticides in the runoff of the UOW. The runoff contains three types of active pesticide substances, with the highest concentration in the two subdistricts being the active substance Diazinon. Active pesticide substances from rice fields in Pakem Subdistrict did not contribute too much to the pesticide pollution on the UOW runoff. Most of the pesticide concentrations in the UOW runoff came from agricultural land.

Abstract

Lake Balekambang, Dieng, has a high level of sedimentation that can affect water quality, so it is necessary to identify organisms to assess the lake's environmental conditions. The use of eDNA methods in Indonesia is minimal, especially in the Dieng area. This research aims to identify the protozoan communities in sediment samples from Lake Balekambang using the Environmental DNA (eDNA) method to assess the lake ecosystem. This study targeting the 18S rRNA gene for single cell eukaryotes. Data analysis was performed using GALAXY and RStudio. Bioinformatics analysis obtained 51,172 reads divided into 48 Amplicon Sequence Variants (ASVs). All specimens were identified as eukaryotes. Protozoa taxa that can be identified are Tritrichomonadidae, Ophryoscolecidae, Gregarinidae, Cyrtolophosididae, Hexamitidae, Isotrichidae, Oxytrichidae, Vannellidae, Vermamoebidae, and other unidentified Eukaryota taxa. Using the eDNA method this study able to identify the protozoan community found in the sediments of Lake Balekambang, Dieng. Protozoa taxa that are identified are taxa that generally inhabit the rumen of ruminants and the gastrointestinal tract of rodents, and are generally pathogens that can cause disease in humans and animals. New knowledge about Environmental DNA Metabarcoding (eDNA) can support research in identifying organisms. This study shows that the eDNA method utilizing the Next Generation Sequencing (NGS) approach are able to identify the protist more effectively, massively, and quickly compared to conventional methods based on morphological characteristics.

Abstract

Wetlands play a crucial role in community livelihood and water security management. The study was conducted in Kiat Ngong and Phapho villages inside the Beung Kiat Ngong (BKN) wetland Ramsar site, in the Pathounphone district, Champasack province. By gathering data from GIS, remote sensing, and ground study for referent and social-economic situations with communities. Farmers from two villages heavily rely on natural biodiversity resources from BKN for consumption and income. By looking at land use types, it shows farmers have paddy and crop fields inside and surrounding Ramsar sites, more than 16% of the catchment area. The majority size is broadleaf evergreen and deciduous forests at 24.9% and 24.3%, with 11.69% claimed as fallow land and located inside Xe Pain NPA. Recently, sources of income have varied, from livestock, rice, fish, cassava, and labor. People earn from aquatic resources an average of 300-400 US dollars/year. Since 2020, cassava has become a main source of income, especially for rich families. Then cassava has expanded quickly to fallow lands inside NPAs, but not yet intends to turn paddy into cassava. Agricultural activities rely solely on surface water. About 70% of paddy areas use water from wetland and rainfall; 20% of households use water from wells and rain; and 10% of people buy purified water from private companies for drinking and cooking. The experiment game to learn how people plan and manage their land and water needs shows that rich families (9% of the population in two villages) are well managed and looking for the alternative crop to grow and thinking of pumping up groundwater for gardening and rice fields, but petrol cost is a concern. While poor families (19% of the population in two villages) are lacking land, they only think of raising cattle and exchanging labor for a living. Collecting golden apple snails for sale becomes a good choice for family income.

Abstract

The Enim River in Muara Enim Regency, South Sumatra, remains vital for various community activities. However, as an open water source, it is vulnerable to waste inputs from surrounding human activities, which impact the river's overall condition. This research aims to assess the water and sediment quality of the Enim River by analyzing key parameters such as pH, TSS, Fe, Mn, and temperature. Additionally, it seeks to explore the correlation between Fe and Mn content in both water and sediment and evaluate the quality status of these elements. The methodology involves descriptive analysis, where the measured values are compared against established quality standards. Correlation analysis is used to examine the relationship between Fe and Mn concentrations in water and sediment. Furthermore, the Pollution Index (PI) and Geo-accumulation Index (Igeo) methods are applied to determine the quality status of water and sediment. The findings indicate that the water quality of the Enim River exceeds acceptable standards for TSS, Iron (Fe), and Manganese (Mn). Regarding sediment quality, the Iron (Fe) levels surpass the Severe Effect Level (Level 3), while Manganese (Mn) remains below the Lowest Effect Level (Level 2). The correlation analysis reveals a strong negative correlation (-1) between Fe and Mn in water and sediment, suggesting a tightly linked inverse relationship. Overall, the Enim River's water quality is classified as Mildly to Moderately Polluted. The sediment quality, however, varies. It is categorized as Extraordinarily to Extremely Severely Polluted for Iron (Fe) and Not Polluted for Manganese (Mn).

Abstract

Joto Reservoir is the largest reservoir in Tikung District and Lamongan District with a standard area of 113 ha. This reservoir is larger than Tuwiri Reservoir 84 ha and Takeran Reservoir 72 ha. The utilization of Joto Reservoir is currently still not optimal without proper management even though the trophic status of the reservoir waters is hypereutrophic. Therefore, the purpose of this study is to analyze the carrying capacity of Joto Reservoir and to analyze the types of fish and the right amount of seeds to be spread in the development of culture based fisheries. The analysis of fisheries carrying capacity determination uses the results of primary water productivity with the Beveridge Index. The results of this study state that the carrying capacity of natural fisheries in Joto Reservoir is 33.8 tons/year. And the right type of fish in the development of culture based fisheries in Joto Reservoir is freshwater lobster (Cherax quadricarinatus). Freshwater lobster seeds are 2 inches in size with a weight of 2-3 g/piece. The target harvest size of freshwater lobster for consumption is 4-5 inches in size with a weight of around 25-45 g/piece. So the number of freshwater lobster seeds that are spread in the development of aquaculture-based capture fisheries in Joto Reservoir is 916,902 tails/year or 305,634 tails/4 months.

Abstract

This study focuses on assessing the coastal conditions in Jambi Province both physicochemical and biological parameters. This combination of assessments previously still had limited understanding. Retrieval of physical parameter data using a multi-parameter water quality analyzer, chemical data using the APHA method and spectrophotometer, and chlorophyll-a data using the Copernicus Marine Environment Monitoring Service (CMEMS). The results, with adjustments to national quality standards and pollution index measurements, showed that the five research stations on the east coast of Jambi experienced light to moderate pollution with a score range of 1.252-5.831. Pollution is in the form of nutrients, especially nitrate. However, the trophic index of the coast is classified as oligotrophic, which ranges between 0.689278 - 0.7599 mg/m3. Otherwise, the high nutrient values are TOM and TN, which have a significant correlation, besides the correlation with DO and pH. Measurements of TN and TP in the water column and sediment have also been carried out, where the water column TN concentration is about 5 times higher than the sediment TN and the water column TP concentration is 7 times lower than the sediment TP. The results of this study will contribute to a better understanding of coastal ecosystem health and its significance for the management of the coastal environment in Jambi as a fisheries catchment area.

Abstract

Upstream of the Progo River in Temanggung Regency, it supports the daily lives of the surrounding community. As time goes by, human activities such as land conversion, deforestation, stone mining, agricultural activities and household waste slowly affect the condition of the waters in the Progo River, so it is necessary to monitor water quality. Plankton can indicate changes in water quality because it is responsive to changes in water quality. This research aims to assess the quality of the water environment using community structure and the saprobic index of plankton. Ten sampling stations were selected using the purposive random sampling method. Plankton were collected using a plankton net, water quality measurements were carried out using a Horiba water checker, and testing in the environmental engineering laboratory. As a result, 81 plankton species had an abundance per station of 805-3,981 ind/L. The diversity index (H') indicates a stable ecosystem, the Evenness Index (e) has a fairly even distribution, and the Dominance Index (D) is at all stations with no dominant species. According to PP No. 22 of 2021, the quality of the Progo River Upstream meets environmental quality standard criteria, except for DO and total N (class I). Based on the saprobic index and bioindicator species, it indicates that all stations belong to the ?-Mesosaprobic. Several types of plankton that can be used as bioindicators of water quality include Cladophora glomerata, Tabellaria sp., and zooplankton, which are Lecane sp.
