“…Sumber pencemaran ini yang berpotensi meningkatkan logam berat yang toksik seperti logam V, Mn, Fe, Cu, Co, Cd, Cr, Pb, dan Hg (Permatasari, 2017). Salah satu bahan pencemar ialah logam berat yang dapat menentukan status mutu kualitas air di suatu perairan sehingga perairan tersebut dapat dikatakan tercemar atau tidak tercemar (Yayu et al, 2015). Logam berat yang mencemari lingkungan perairan, 90% akan terendap di dalam sedimen (Amin et al, 2011).…”

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).

“…Akibat aktivitas penambangan timah, perairan ini tampak sangat keruh dan terjadi pendangkalan oleh lumpur pada dasar perairan. Aktivitas penambangan timah yang terus berlangsung dapat memberikan dampak negatif bagi lingkungan, salah satunya dapat meningkatkan kandungan logam berat seperti Cadmium (Cd) yang tidak dapat terurai dan akan terakumulasi pada lingkungan (Gerhanae & Permanawati, 2015;Kurniawan et al, 2014;Sari et al, 2017). Cadmium (Cd) merupakan logam berat berbahaya dengan tingkat toksisitas yang tinggi (Chauhan & Solanki, 2018).…”

Bangka Belitung Province is one of the largest tin producing area in Indonesia. One of the mining sites located on the Sampur Beach, Kebintik Village, Central Bangka Regency. Tin mining activities can increase heavy metals harmful to the environment, such as Cadmium (Cd). This research aimed to measure Cd levels in sediment and seawater, to isolate and identify Cd resistant bacteria from sediment. Cd metal was analyzed using Atomic Absorption Spectrophotometer (AAS). The average Cd metal level in seawater is 0,0080 ppm and in sediment is 0,0086 ppm. Bacteria were isolated using Zobell 2216E media with the spread plate method. The isolated Bacteria were tested for resistance to Cd with concentration of 20 ppm, 50 ppm, 80 ppm, 100 ppm, and 120 ppm. From 16 bacterial isolates that have been obtained, 7 isolates were resistant to all concentrations, 1 isolate was resistant to 50 ppm, 1 isolate was only resistant to 20 ppm, and 7 isolates were not resistant. Based on the results of the analyzed, the seven isolates of resistant bacteria have similarity with Halomonas sp. (R2 and R3), Neisseria sp. (R4), Cupriviadus sp. (R5), Bacillus sp. (R11), Alcaligenes sp. (R12), and Roseobacter sp. (R13).

“…Heavy metals are metal elements that have density exceeds 5 g/cm3 which are classified as pollutants and are dangerous because they will accumulate in the water column, sediments, organisms and cannot be degraded naturally [1]. Heavy metals are one of the factors in determining the status of water quality [2]. Heavy metal concentrations that have exceeded the threshold will have an impact on the ecosystem around these waters [3], [4].…”

The Rupat Strait is a water area located between Rupat Island and Dumai City. This area is growing rapidly which is characterized by increasing coastal residential areas, commercial centers, industries, ports and also increasing marine transportation. This increase in activity can lead to a decrease in the water quality of the Rupat Strait. This study aims to analyze the water quality of heavy metals Cadmium (Cd), Cuprum (Cu), Lead (Pb), Zinc (Zn) and Nickel (Ni) in the waters of the Rupat Strait. Sampling of surface water using sample bottles was carried out at 9 observation stations from the waters of West Rupat to South Rupat, then testing the water samples in the laboratory. The results of the analysis show that the lead and nickel values still meet the threshold values set by the Minister of Environment No.51 of 2014. A total of 30% of the sample points for cadmium testing water do not meet the quality standards and have been polluted. Meanwhile, the values of cuprum and zinc have exceeded the specified quality standards and have polluted the waters of the Rupat Strait. There is a need for a mechanism from various aspects to maintain water quality that still meets the threshold and certain efforts are needed to reduce heavy metal pollution, namely cuprum and zinc in the waters of the Rupat Strait and its surroundings.
