Abstract

The concentrations of Cd, Cu, Pb, Zn, Ni and Fe were determined in the marine gastropod Nerita lineata collected on May 2005 from the intertidal zone of fourteen stations in Dumai, Indonesia (mean length 21.43 – 24.04 mm) and ten stations in Johor, Peninsular Malaysia (mean length 22.61 – 26.60 mm). The results of the present study showed that metal concentrations in the shell, operculum and soft tissue of N. lineata varied at different sampling stations. The mean concentrations of Cd, Cu, Pb, Zn, Ni and Fe in the samples collected from Dumai were 4.14; 5.90; 44.43; 3.74; 20.73; 24.91 μg/g in shell; 4.16; 7.31; 51.78; 17.63; 23.52; 30.60 μg/g in operculum and 0.71; 15.16; 9.34; 94.69; 5.08; 397.96 μg/g dry weight in the total soft tissue; whilst those collected from Johor were 4.18; 5.06; 59.84; 4.8122; 19.29; 31.60 μg/g in shell; 4.73; 6.51; 60.57; 19.48; 20.68; 34.92 μg/g in operculum and 1.24; 18.02; 19.75; 95.09; 5.57; 473.56 μg/g dry weight in the total soft tissue, respectively. Samples of N. lineata from both Dumai and Johor tend to show similar trend in metal accumulation in which the concentrations of Cd, Pb and Ni decreased in the order: operculum > shell > soft tissue whilst Cu, Zn and Fe in the order of soft tissue > operculum > shell. In general, samples from Johor accumulated higher heavy metal concentrations when compared to samples from Dumai, except for Cu and Ni in the shell and operculum, which exhibited vice versa situation. Higher concentrations of metals were recorded in samples collected from the stations close to the industrial and anthropogenic activities. However, most of the concentrations were still comparable to the previous reported studies from other geographical areas.

Abstract

Heavy metal concentrations in sediment collected from Dumai coastal waters have been studied by using sequential extraction technique to determine the distribution and geochemical speciation (EFLE, acid reducible, oxidisable organic and resistant) of Cd, Cu and Ni. The results showed that the highest concentrations of total Cd was in Cargo Port area and the lowest in Penyembal, whilst for Cu and Ni the highest concentrations were in Ferry Port and the lowest in Batu Panjang.  The total concentrations of Cd, Cu and Ni ranged from 0.65 – 1.82, 1.84 – 13.16 and 7.68 – 17.98 µg/g dry weight, respectively. Higher metal concentrations were detected in the eastern and central parts of Dumai city center where most of anthropogenic activities are concentrated. However, most of the concentrations of Cd, Cu and Ni were still below the ERL and ERM values. Only at few stations, especially in the eastern and central parts of Dumai, showed Cd concentrations exceed the ERL but still well below the ERM values. Metal concentrations in 78.26% (Cd) and 91.30% (Cu and Ni) of the sampling stations were dominated by resistant fraction indicating natural origin of these metals. Non resistant fractions, however, were found higher than resistant fractions at Pelintung, Pertamina, Cargo Port, Penyembal and Batu Panjang for Cd; Penyembal and Batu Panjang for Cu and Pelintung and Guntung for Ni. These findings indicated that anthropogenic inputs of Cd, Cu and Ni occurred in these stations. For all sampling site groups, Cd, Cu and Ni were mostly accumulated in the resistant fraction (55.28 – 58.31%; 65.02 – 91.84% and 50.08 – 66.88% of the total concentrations respectively) which indicated that the mobility and anthropogenic inputs of these metals in Dumai coastal waters were quite low.

Abstract

Analisis konsentrasi logam berat Pb, Cu dan Zn dalam jaringan lunak moluska (Geloina sp dan Calliostoma sp) dan sedimen dari perairan muara Sei Jang Riau Indonesia telah dilakukan. Pada umumnya konsentrasi logam tersebut dalam jaringan lunak moluska lebih tinggi dari konsentrasi dalam sedimen, kecuali logam Pb dalam Geloina sp yang relatif lebih rendah dibanding dalam sedimen. Geloina sp mengakumulasi logam Zn lebih dari tiga kali lipat dari konsentrasi dalam sedimen, sedangkan Calliostoma sp mengakumulasi logam Cu lebih dari empatbelas kali lipat konsentrasi logam tersebut dalam sedimen. Peningkatan konsentrasi logam berat lebih terlihat jelas di sekitar kawasan bekas penambangan bauksit, galangan kapal dan di kawasan aktivitas penduduk. Akumulasi logam didapatkan lebih tinggi dalam jaringan lunak moluska yang berukuran lebih besar dimana hal ini mengindikasikan bahwa ukuran merupakan faktor penting dalam akumulasi logam berat oleh moluska. Indeks Akumulatif menunjukkan bahwa akumulasi logam tertinggi oleh moluska terjadi di kawasanbekas penambangan bauksit dan Geloina sp lebih baik dijadikan sebagai indikator untuk logam Zn sedangkan untuk logam Cu dan Pb lebih baik digunakan Calliostoma sp.Kata kunci : logam berat, sedimen, moluska, indeks akumulatifAbstractConcentrations of lead, copper and zinc were measured in molluscs (Geloina sp and Calliostoma sp) andsediment samples collected from Sei Jang estuary Riau Indonesia. Concentrations of those metals in molluscswere higher than in sediments, except for lead in Geloina sp which was slightly lower than sediments.Geloina sp accumulates zinc more than threefold of the concentration in sediment, whilst Calliostoma spaccumulates copper more than fourteen-fold of the sediment concentrations. Elevated concentrations of heavymetals in an ex-bauxite mining area, dockyard and anthropogenic activities were found. Accumulation ofmetals in molluscs varied between sizes where larger size accumulated more metals than smaller size indicatingthat size is an important consideration for metal accumulation. Average accumulative indices indicated thathighest metals accumulation by molluscs occurred in the area of an ex-bauxite mining activities. These indicesalso suggested that Geloina sp was better to be used as indicator organism for zinc, whilst Calliostoma sp wasconsidered to be suitable indicator organisms for the accumulation of copper and lead.Key words : heavy metals, sediment, mollusc, Accumulative index

Abstract

One of the interesting and environmentally friendly microbiology strategies and approaches to control the impact of microplastics is to approach bioremediation technology by harnessing the potential of microbes or indigenous bacteria (local bacteria).  Dumai sea waters currently show a high enough of microplastic pollution which allows the potential of indigenous bacteria to adapt to a plastic environment. The purpose of this study is to isolate and identify indigenous bacteria to degrade plastics from the sea waters of Dumai and to know whether or not there is a difference in the number of bacteria found between stations in this study. This research was conducted in October-December 2020 with experimental methods at the Marine Microbiology Laboratory Faculty of Fisheries and Marine Science Universitas Riau. Based on the results of the study, 12 bacterial isolates were isolated from the research stations.  Isolates of these bacteria have diamaters ranging from 0.2-1.1 cm. Microplastic degradation test results by bacteria found that ISL 10 is an isolate that shows the highest PET degradation activity, which is 17.27% and the diameter of biofilm formation 0.8 cm. Based on biochemical and morphological tests, similar results were obtained that ISL 10 bacteria are a bacterium of the genus Bacillus. The most bacterial colonies were seen in statiun IV (TPI) with an average number of bacteria of 214.9 x 104 CFU/ml.

Abstract

In Indonesia, almost all clean water supply for the community is carried out by the government-owned drinking water company, namely the Regional Drinking Water Company (PDAM) and is directly under the auspices of the city government. For Pekanbaru City, the provision of clean water services is carried out by the Regional Owned Enterprises, Regional Drinking Water Company (PDAM) Tirta Siak which is under the auspices of the Pekanbaru City Government. . Until now PDAM Tirta Siak still has problems relating to the amount of drinking water production. Clean water management by PDAM Tirta Siak Pekanbaru City has various problems. These problems include technical and non-technical problems. However, problems often occur due to the condition of the water source itself, often the condition of water quality, quantity and continuity is unstable. Water management problems occur due to many factors that influence it. The purpose of this study was to determine the status of the sustainability of the Tirta Siak Regional Drinking Water Company in Pekanbaru City based on 3 dimensions, namely ecology, economy and social. The analytical method uses a multi-disciplinary rapid assessment with MDS (Multidimensional Scaling) analysis. The results of the analysis show that the sustainability index value in the ecological dimension is 53.6% with a fairly continuous status where the sensitive factor is water availability, the economic dimension is 50.9% with a fairly continuous status where the sensitive attribute is collection effectiveness, while the social dimension is 49.9% with status less sustainable where the sensitive attribute is the employee training ratio.
