Abstract

Microplastics are particles that have a size of 5 mm, where its existence might be able to contaminate the biota in the aquatic environment. This research was conducted in the coastal waters of Bengkalis Island in December 2020 with the aim to determine the types and analyze its abundance of microplastics in each area with different sources of anthropogenic input in the north and south Bengkalis Island. Sampling of sea water for microplastic analysis was done using plankton net (diameter 30 cm and mesh size 30 μm) from six sampling stations. Thirty six individual samples of Duri (Arius maculatus), Lomek (Harpodon nehereus), and Biang (Setipinna breviceps) fish were obtained with the help of local fishermen in each sampling location. The results showed that the types of microplastics found in seawater samples are fiber and film with average abundance ranges between 9.58 particles/m3 - 40.42 particles/m3. The highest abundance was found in station 6 (60.83 ± 8.61 particles/m3 and 20.00 ± 8.94 particles/m3) for fiber and film, whilst the lowest abundance was found in station 3 (12.50 ± 5.24 particles/m3 and 6.67 ± 6.06 particles/m3) for fiber and film, respectively. The average abundance of microplastics found in the digestive tract of fish was 62.96 particles/ind. which consisted of fiber, film and fragment. The highest microplastic abundance was found in Duri fish (72.22 particles/ind.), whilst the lowest was found in Lomek fish (55.56 particles/ind.). Although the abundance of microplastic in coastal waters of north Bengkalis were higher than that in the south of Bengkalis Island, statistically they were significantly different. This was presumably due to differences in oceanographic influences such as current and waves between the two water masses as well as anthropogenic activities in both areas that can affect the spread and distribution of microplastics.Keywords: plastic waste, Bengkalis waters, demersal fish, pelagic fishABSTRAKMikroplastik adalah partikel yang memiliki ukuran 5 mm, di mana keberadaannya dapat mencemari biota di lingkungan akuatik. Penelitian ini dilakukan di perairan pantai Pulau Bengkalis pada Desember 2020 dengan tujuan untuk menentukan jenis dan menganalisis kelimpahan mikroplastik di setiap wilayah dengan berbagai sumber input antropogenik bagian utara dan selatan Pulau Bengkalis. Pengambilan sampel air laut untuk analisis mikroplastik dilakukan menggunakan plankton net (diameter 30 cm dan ukuran jala 30 μm) dari enam stasiun pengambilan sampel. Tiga puluh enam sampel individu ikan Duri (Arius maculatus), Lomek (Harpodon nehereus), dan Biang (Setipinna breviceps) diperoleh dengan bantuan nelayan lokal di setiap lokasi pengambilan sampel. Hasil penelitian menunjukkan bahwa jenis mikroplastik yang ditemukan dalam sampel air laut adalah fiber dan film dengan kisaran kelimpahan rata-rata antara 9,58 partikel/m3 - 40,42 partikel / m3. Kelimpahan tertinggi ditemukan di stasiun 6 (60,83 ± 8,61 partikel / m3 dan 20,00 ± 8,94 partikel / m3) untuk fiber dan film, sedangkan kelimpahan terendah ditemukan di stasiun 3 (12,50 ± 5,24 partikel / m3 dan 6,67 ± 6,06 partikel / m3) untuk fiber dan film. Kelimpahan rata-rata mikroplastik yang ditemukan dalam saluran pencernaan ikan adalah 62,96 partikel / ind. yang terdiri dari fiber, film dan fragmen. Kelimpahan mikroplastik tertinggi ditemukan pada ikan Duri (72,22 partikel / ind.), sedangkan yang terendah ditemukan pada ikan Lomek (55,56 partikel / ind.). Meskipun kelimpahan mikroplastik di perairan pantai Bengkalis utara lebih tinggi daripada di selatan Pulau Bengkalis, secara statistik mereka berbeda nyata. Ini mungkin karena perbedaan dalam pengaruh oseanografi seperti arus dan gelombang antara dua massa air serta aktivitas antropogenik di kedua daerah yang dapat mempengaruhi penyebaran dan distribusi plastik mikro.Kata kunci: sampah plastik, perairan Bengkalis, ikan demersal, ikan pelagis

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.

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

The aim of this research was to find out the relationship between metals Pb, Cu, Zn concentration in sea water and in snail C. montagnei, to determine the pollution level of Desa Gemuruh coastal waters of Kundur Island, as well as to evaluate the safety level of the snail for human consumption. The research was conducted in February – March 2017 by collecting samples from three different stations from Desa Gemuruh coastal waters. Metal concentration analysis was done in Marine Chemistry Laboratory, Faculty of Fisheries and Marine Sciences University of Riau. The results showed that the average Pb, Cu, Zn concentrations in sea waters were 0,0408 mg/L; 0,0438 mg/L; and 0,1424 mg/L, while in snails were 1,0315 μg/g ; 0,9261 μg/g ; 54,1507 μg/g respectively for Pb, Cu, and Zn. The linear regression showed that the raising of Pb and Zn concentration in sea waters, were followed by increasing metal concentrations in snails, but Cu concentration in sea waters were not followed by its increasing concentrations in snails. The larger the body size of the snail the higher metals were accumulated by the snail. This study also showed that MPI values obtain from Desa Gemuruh coastal waters of Kundur Island 3,7260 were classified as lower than other research locations. Snails from this coastal waters are still considered to be safe to be consumed by human with safety level were 6,7864 Kg per week for Pb, 1079,7840 Kg per week for Cu, and 36,1953 Kg per week for Zn.Keywords: Heavy metals, marine pollution, Cerithidea montagnei, Kundur Island

Abstract

Abstract Increased CO2 content causes an increase in greenhouse gas emissions in the atmosphere that cause global warming which then trigger climate change. One of the marine resources that acts as an absorber of CO2 in mitigating global warming is the seagrass ecosystem. In the waters of Nirwana Beach of West Sumatra, seagrass (Thalassia hemprichii) is one and only important types of seagrass. This study was conducted in December 2017-February 2018 in Nirwana Beach of Padang City West Sumatra, which aims to estimate the biomass, the average C-organic content and to identify the seagrass body part as the largest carbontrap as well as to estimate the relationship between the carbon storage and density of seagrass T. hemprichii. Sampling andmeasurement of water quality was done byusing quadratic transect at 3 stations. The results of the study showed that the largest biomass and largest carbon storge from all study sites were at the Bottom of Substrate (roots and rhizomes) with 315.46 gdw/m2 and 81.95 gC/m2. The highest average C-organic content in all sites was forwad on the root of the seagrass with a value of 27.76%. Relationship between carbon stroge and density of seagrass is best stronge y =16.11+15.56x;R² = 0.89; r = 0.79. Keywords: Global Warming, Seagrass, Biomass, C-organic
