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

Sampah plastik merupakan salah satu dari sekian banyak jenis sampah yang cukup menyita perhatian. Kontribusi sampah plastik di perairan dalam jumlah besar akan sangat mengganggu ekosistem di perairan tersebut. Kalimantan Timur merupakan daerah yang mudah ditemukan keberadaan sampah plastik, hal ini dikarenakan produksi dan penggunaan plastik terus meningkat setiap tahunnya. Keberadaan sampah plastik di perairan disebabkan oleh ulah manusia, baik secara langsung membuang sampah ke perairan maupun secara tidak langsung terbawa arus. Penelitian sampah plastik di perairan Muara Sembilang dilakukan untuk mengetahui keberadaan makroplastik, mengidentifikasi jenis makroplastik, dan menganalisis kelimpahan dan kepadatan makroplastik berdasarkan lokasinya. Pengambilan makroplastik dilakukan dengan menggunakan alat ambil (0,3 m x 0,1 m x 0,1 m) di 4 stasiun dengan masing-masing 3 plot dengan jarak antar plot 10 m. Hasil penelitian menunjukkan jenis film merupakan terbanyak ditemukan di empat stasiun dengan total 18 item, diikuti fragmen dan fiber dengan total masing-masing 3 item. Tidak terdapat perbedaan yang signifikan kelimpahan makroplastik antar stasiun pengamatan.
