Abstract

This study aims to determine the levels of nitrogen compounds in the Mahakam river at high and low tide, and to compare it with the quality standard East Kalimantan Timur Regulation Number 02 0f 2011 concerning Water Quality Management and Water Pollution Control. The data obtained in the field and the results of the analysis in the laboratory are displayed in the form of tables and graphs. The data is presented based on a descriptive picture to get conclusions from the results of the study, with an independent sample t-test and compared the average between the two cases. The levels of Ammonia, Nitrite and Nitrate at high tide were significantly lower than at low tide. lower than at low tide. Ammonia levels at high tide ranged from 0.382- 0.424 mg/L, and have exceeded the quality standard threshold of regional Regulation of East Kalimantan Province Number 02 of 2011. Nitrite levels at high tide range from 0.027- 0.068 mg/L and ar low tide 0.04 - 0.068 mg/L, and still meet the quality standards of East Kalimantan Province Regulation Number 02 0f 2011.Nitrate levels at high tide range from 0.89 – 1.20 mg/L and at low tide 1.00 – 1.20 mg/L, which still meets the quality standards of East Kalimantan Province Regualation No. 01 of 2011. The levels of Ammonia, Nitrite and Nitrate at high and low tide were not significantly different.

Abstract

Heavy metals are compounds that can affect the quality of a waters. Various kinds and types of heavy metals that enter and settle in sediments can cause diversity to decrease to the extinction of organisms in the waters. This study was aimed to determine the content of Cd, Pb, and Cu accumulated in water, substrate, and gastropods obtained from Kersik Village, Kutai Kartanegara Regency, East Kalimantan. Samples of water, substrate, and gastropods were collected from 4 stations with 3 repetitions. Water samples, substrates, and gastropods were analyzed using AAS. Concentration ranges of Cd, Pb, and Cu in water were 0.003 - 0.011 mg/L; 0.161 - 0.731 mg/L; and 0.007 - 0.009 mg/L, respectively. The concentration ranges of Cd, Pb, and Cu on the substrate were 0.021 - 0.182 mg/kg; 19.5 - 31.12 mg/kg; and 14.29 - 15.47 mg/kg, respectively. In gastropods, the range of Cd concentrations was 0.509 - 0.675 mg/kg, while for Pb and Cu were 15.96 - 21.52 mg/kg and 57.78 - 92.4 mg/kg, respectively. The concentration of Pb in gastropods at all stations has exceeded the quality standard based on SNI-7387-2009, while the concentration of Cu in gastropods at all stations has also exceeded the quality standard based on BPOM No.03725/B/SK/89. Bioconcentration Factor (BCF) of organisms to sediment (BCFo-s), shows the ability to accumulate Cu in Gastropods which is higher than Cd and Pb. Bioconcentration Factor (BCF) analysis of organisms to water (BCFo-w), showed that the accumulation of Cd, Pb, and Cu were in the low, medium, to high categories. The average comparison of concentrations of the three heavy metals at each observation station was not significantly different (sig. > 0.05).

Abstract

Miang Island is a transportation route for coal ships and a place for loading and unloading coal, then there are also oil palm companies around this island. On this island there are also still islanders who carry out household activities in this area, such as washing activities, thus producing household waste in the waters on this island. Therefore, community activities carried out on this island can contribute to the burden of pollution of waters and reef fish in these waters, therefore it is necessary to conduct research on heavy metal levels that have contaminated organisms in these waters related to the pollution conditions that occur. This research was conducted in February 2023 in the waters of miang island and analyzed water quality and heavy metal content in the water quality laboratory and soil laboratory of mulawarman university. The parameters that will be observed are the analysis of heavy metals lead (Pb) and copper (Cu) found in reef fish meat and statistical analysis using the Chi-Square test by comparing heavy metal content in reef fish against water quality data. In this study, reef fishes that have been analyzed are Lutjanus decassatus, Pentapodus caninus, Ephnephlesu ongus, Lethrinus erythropetrus, Balistapus undulatus, Gymnocranius microdon, Plectropomus leopardus, and Priacanthus meeki. All fish species contain heavy metals lead (Pb) and copper (Cu), this can be caused by activities carried out by local communities that can disturb water conditions and have an impact on fish, In the Chi-square analysis that has been carried out on water quality at each station on Miang Island, the results obtained water quality gives an influence on heavy metals in the bodies of reef fish that have been caught in this study. This can be caused by water quality that is affected by heavy lead (Pb) and copper (Cu) from human activities in these waters, such as ship loading and unloading activities, and ship transportation routes.

Abstract

Plastic waste is the type of waste that is most commonly found in our environment. Plastic waste that decomposes and degrades into smaller particles is called microplastic. Small-sized microplastics (<5 mm) can accumulate in water sediments and are difficult to decompose, making this material remain in the environment for a long time. This research aims to determine the microplastic content in the sediment of the main gate garden pond and FEB garden pond at Mulawarman University. This research was carried out for 3 months starting from determining the research location until microplastic analysis. The research location was determined by purposive sampling in 2 garden ponds with 5 stations in each pond. Analysis of microplastic content in sediment was carried out using a separation method based on specific gravity using NaCl solution. Microplastic identification was carried out using a stereo microscope (8-16x magnification). The results of this research show that the types of microplastics found were fiber, fragments and films with the dominant type of microplastic being fiber. The highest abundance of microplastics was found in the FEB garden pond at 4,350 particles/kg, while in the main gate garden pond, it was 3,800 particles/kg.

Abstract

This study aimed to analyze the concentrations of manganese (Mn) and iron (Fe) in both water and sediment samples from the Sanga-Sanga River, Kutai Kartanegara Regency, East Kalimantan Province. The research was conducted from October to December 2024 at three stations representing the upstream, midstream, and downstream sections of the river. Sampling was performed using a purposive method based on site characteristics, and analyses were carried out both in situ and at the Water Quality Laboratory, Faculty of Fisheries and Marine Science, Mulawarman University. The concentrations of Mn and Fe were compared with the Indonesian river water quality standard (Government Regulation No. 22 of 2021) and sediment quality guidelines established by the Australian and New Zealand Environment and Conservation Council (ANZECC, 2000). The results showed that Mn concentrations in river water ranged from 0.325 to 1.181 mg/L, exceeding the permissible limit of 0.1 mg/L, while Fe concentrations ranged from 0.3475 to 0.468 mg/L, surpassing the standard of 0.3 mg/L. In sediments, Mn concentrations ranged from 42.38 to 964.47 mg/kg and Fe concentrations from 11,341.23 to 50,344.72 mg/kg, with several stations exceeding the ANZECC guideline limits. Higher concentrations were generally found at midstream and downstream stations, particularly in areas influenced by coal mining, barge transport, and ship repair activities. These findings indicate that the Sanga-Sanga River has experienced notable contamination by Mn and Fe, primarily due to anthropogenic activities related to coal industry operations. Continuous monitoring, stricter waste management, and the implementation of pollution control measures are recommended to prevent further environmental degradation and protect aquatic ecosystems.
