Abstract

A preliminary study on the response of amphipod exposed to contaminated sediments of Jakarta Bay was carried out in October 2009. The objective of the study was to determine the mortality rate of amphipod in response to exposure of contaminated sediments. Seven sediment samples were taken from the bay, i.e, reference site (St. A), and six-contaminated sites (St. B3, B5, C3, C5, D3, and D5). Amphipod (Grandidierella sp.) was collected from reference site. The study showed that average of mortality rate of amphipod ranged between 50.0 and 76.3% at contaminated sediments and 38.3% at reference sediments. There was significant difference on mortality rate of amphipod exposed to sediments of reference site and that of contaminated sites. The mortality of Grandidierella sp. was not strongly correlated with the concentration of Pb and Cu in contaminated sediments. The critical mortality factor of amphipod in this study might be due to variation in grain size of sediments and short period of acclimatization.

Abstract

Chronic sediment toxicity tests could be used to evaluate the effects of sediment on critical stages in the life of an organism like invertebrate larvae and microalgae. Microalgae play an important role in aquatic ecosystem due to their role as producer in food chain producing organic matter and oxygen through photosynthesis process. This paper aimed to assess sediment quality of Semarang water using chronic sediment toxicity test. Research was conducted by testing 13 sediment samples from Semarang coastal region in August, 2010. Results showed that sediments exposed for 96 hours were still able to stimulate the growth of C. gracilis eventhough the copper concentration was above standard value provided by the CCME. The conclusion from this research was that sediment in Semarang still in good condition and can support growth of C. gracilis as primary producer. Chronic sediment toxicity test using C. gracilis could be combined with heavy metal measurement for sediment quality asessment.

Abstract

Penggunaan organisme uji yang sesuai dengan bahan yang diuji adalah faktor yang sangat penting dalam bioassay. Berbagai organisme uji tropis telah banyak digunakan di Indonesia seperti ikan, bulu babi, dan fitoplankton. Fitoplankton seperti Chaetoceros gracilis, Tetraselmis sp., Isochrysis sp., Pavlova sp., yang hidup di kolom air telah dimanfaatkan dengan baik untuk bioassay. Namun, fitoplankton bentik seperti Nitszchia sp. belum dikenal secara luas. Tulisan ini bertujuan untuk menguji potensi Nitzschia sp. sebagai biota uji sedimen. Parameter yang diteliti adalah kurva pertumbuhan dan sensitifitas terhadap kadmium dan tembaga. Hasil penelitian menunjukkan bahwa pertumbuhan Nitszchia sp. meningkat pesat pada hari keempat hingga hari keenam. Setelah hari keenam, pertumbuhannya cenderung menurun. Kepekaan terhadap toksikan diindikasikan dengan nilai IC50 (Inhibition Concentration) sebesar 0,078 mg/Luntuk tembaga dan 0,26 mg/L untuk kadmium. Kesimpulan dari penelitian ini adalah Nitszchia sp. dapat digunakan sebagai organisme uji untuk bioassay sedimen karena memenuhi persyaratan kepadatan minimum uji serta sensitif terhadap kadmium dan tembaga. Nilai LOEC dan NOEC untuk tembaga berturut-turut sebesar 0,056 dan 0,032 mg/L sedangkan untuk kadmium sebesar 0,18 dan <0,18 mg/L. Nitzschia sp. tiga kali lebih sensitif terhadap tembaga dibandingkan dengan kadmium.

Abstract

In Copper (Cu) based antifouling (AF) paints Cu was largely used as booster biocide after organotin was banned. Cu is micronutrient which is important in photosynthesis process because Cu is an essential metal as component of enzyme and electron transport chain. But in certain dosage, Cu could be toxic to marine organism. Chaetoceros gracilis and Isochrysis sp. are dominant microalgae in aquatic ecosystem. In this study the effect of Cu and Cadmium (Cd) on two marine microalgae, C. gracilis and Isochrysis sp. were compared. Toxicity test was based on American Standard for Testing Material (ASTM). IC50-96 h of Cd as reference toxicant was 2,370 mg.L-1 for C. gracilis and 490 mg.L-1 for Isochrysis sp. IC50-96 h of Cu to growth of C. gracilis was 63.75 mg.L-1 and Isochrysis sp. was 31.80 mg.L-1. Both Cd and Cu were inhibited growth of microalgae. Based on IC50-96 h value, it could be concluded that Cu was more toxic than Cd. Toxicity of Cu was 37 times stronger than Cd for C. gracilis and 15 times for Isochrysis sp. It was estimated that at concentration 10 mg.L-1 Cu does not show observable effect (NOEC) to C. gracilis and 5 mg.L-1 to Isochrysis sp. The lowest observable effect of Cu (LOEC) to C. gracilis was at concentration 17 mg.L-1 and 10 mg.L-1 for Isochrysis sp.

Abstract

Indication of accumulation of heavy metal in sediments will lead to problem for shore and sea ecosystems, biota living in that area and human’s health. The research is aiming to analyse the toxicity of sediment from thirty one locations in Jakarta Bay using Perna Viridis. High amount in larval abnormality found in sediments from the area near mainland and estuary are an indication of high influence of waste from anthropogenic activities from Jakarta mainland. These areas are down stream of Cengkareng Drain, Kamal River, Grogol River and Cakung River, area around sea transportation and North Jakarta Integrated Industrial Area. Sediment of Jakarta Bay, especially coming from estuary area and near to the land area causes an increase in green mussel larval abnormality. This indicates the high of waste influence from anthropogenic activity from Jakarta land area.

Abstract

Sediment of 16 sites in the Kelabat Bay were monitored for metal contamination and toxicity in 2006. Two patterns of metal contaminants distribution in the sediment were observed. Higher concentrations of lead and copper were found in March than those in July, and so was in the inner bay than those observed in the outer bay, while different pattern was observed for cadmium concentration. The highest lead concentrations were observed at site 7 (inner bay) both in March and July. Although elevated levels of cadmium, lead and copper were observed in sediments, they were still in the tolerable level for marine life. Sediment of the bay was also evaluated for its toxicity using marine phytoplankton, Chaetoceros gracilis and sea urchin, Tripneustes gratila. Results of the tests reveal that no toxic effects of sediment to the growth of phytoplankton were observed, but to sea urchin fertilization of the sediment may have toxic effect.

Abstract

Nowadays, contamination monitoring in Indonesia still focused on traditional method like only depend on measurement of chemical and physical parameter.  In addition, the use of organism, known as bioindicator brings some advantages such as knowing about habitat alteration and relationship between organism and environment. Fish from genus Oryzias had been known in Malaysia and Japan as a sensitive bioindicator. One of species, O. javanicus, was found in Kramat Kebo estuary, West Java, Indonesia. This preliminary study aims to determine metal distribution in water and sediment in Kramat kebo estuary, as a habitat of O. javanicus. It is also a preliminary study to assess possibility of O. javanicus as a bioindicator of heavy metal contamination in coastal area.  Sampling was conducted on March and September, 2014 and analysis of total metal was done by Atomic Absorbance Spectrophotometry. Result showed that metal in water still below the threshold value by Ministry of Environment. Metal in sediment analyzed by Sediment Quality Guidelines Quetiont (SQG-Q) index, showed that all stations has SQG-Q value < 0.1, which is means that Kramat Kebo estuary is unimpacted area. We conclude for this preliminary study that existence of O. javanicus were related to less polluted of heavy metal in estuary and it suitable for bioindicator of uncontaminated heavy metal area.

Abstract

Penggunaan TBT sebagai cat antifouling telah dilarang di dunia, oleh karena itu diperlukan bahan alternatif yang dapat menggantikannya. Fase awal dari fouling adalah pembentukan biofilm yang melibatkan bakteri. Cymodocea serrulata dan Syringodium isoetifolium diketahui berpotensi antibakteri terhadap Vibrio harveyii dan Bacillus subtilis. Sebelum dikembangkan lebih jauh sebagai bahan aktif cat antifouling, perlu diteliti keamanan dari lamun tersebut terhadap produsen primer perairan, salah satunya Chaetoceros graclis. Ekstrak kedua jenis lamun tersebut dipaparkan terhadap diatom selama 96 jam pada kondisi laboratorium dan dianalisis pengaruhnya terhadap pertumbuhan fitoplankton. Ternyata, S.isoetofolium menunjukkan penghambatan pertumbuhan diatom. Hasil dari uji anti bakteri dan bioassay menunjukkan bahwa lamun C. serrulata lebih potensial untuk dikembangkan sebagai bahan aktif cat antifouling daripada S. isoetifolium.

Abstract

Jakarta Bay coastal ecosystem is known suffered from water pollution and habitat degradation. Solid and fluid waste from households and several industrial areas flow and ended up in the bay. Ecotoxicological studies are needed to assess the effects of pollutant on marine organism, including phytoplankton as the primary producer. Therefore chemical analysis and toxicity test were performed to investigate the impact of Jakarta Bay Sediments to marine diatoms Chaetoceros gracilis. Heavy metals concentration especially Cu, Pb, Cd, and Hg in the sediments were lower than in previous studies. It could be related to the stricter environmental regulations which started enforced at the end of 1990s. Meanwhile, PAH and pesticide were higher than in previous studies. Increasing activities and maritime traffic in surrounding area of Tanjung Priok Port area and most likely comes from other adjacent harbors (Muara Baru, Muara Angke, and Marina Ancol harbor) and the massive usage of the pesticide compound in the households of the Jakarta City area were suspected to be the reasons. Estuaries area and locations <10 km were identified and predicted would produce harmful effects since the concentration of Zn and Hg in those area exceeded Probable Effects Level (PEL) of Sediment Quality Guidelines (SQG). The growth responses of Chaetoceros gracilis were varied greatly. Most of the sites (24 from 31 sites) showed inhibition effects on the growth of diatoms, ranged from 1.75-35.33 % (17.75±9.59 %) relative to control, with the highest inhibition value was at Cengkareng Drain estuary (M2). The relationship between the concentration of contaminants and the inhibition response could not be clearly explained, however, there is an assumption that low concentrations of some heavy metals were suspected to give adverse effects on diatom’s growth.Keywords: sediment, toxicity, marine diatoms, Chaetoceros gracilis, Jakarta BayEkosistem Teluk Jakarta dikenal mengalami pencemaran air dan degradasi habitat. Limbah cair dan padat berasal dari perumahan dan industri mengalir dan berakhir di teluk tersebut. Kajian ekotoksikologi diperlukan untuk mengetahui pengaruh pencemar terhadap organisme laut termasuk fitoplankton sebagai produsen primer. Analisis kimia dan uji toksisitas dilakukan untuk mengetahui dampak sedimen Teluk Jakarta terhadap diatom laut Chaetoceros gracilis. Konsentrasi logam berat terutama Cu, Pb, Cd, dan Hg dalam sedimen lebih rendah dari penelitian sebelumnya. Hal tersebut berkaitan dengan peraturan lingkungan ketat yang mulai diberlakukan pada akhir 1990-an. Namun demikian, konsentrasi PAH dan pestisida lebih tinggi dari penelitian sebelumnya. Hal tersebut diduga kuat akibat dari peningkatan aktivitas dan lalu lintas maritim di daerah sekitar Pelabuhan Tanjung Priok, juga kemungkinan besar berasal dari pelabuhan lain yang berdekatan (Muara Baru, Muara Angke, dan pelabuhan Marina Ancol) serta akibat penggunaan besar-besaran senyawa pestisida kegiatan rumah tangga di wilayah Kota Jakarta. Daerah dan lokasi estuaria <10 km diidentifikasi dan diprediksi akan menghasilkan efek berbahaya karena konsentrasi Zn dan Hg di area tersebut melebihi Probable Effects Level (PEL) dari Pedoman Kualitas Sedimen (SQG). Respon pertumbuhan diatom laut Chaetoceros gracilis sangat bervariasi. Sebagian besar stasiun (24 dari 31 stasiun) menunjukkan efek penghambatan pada pertumbuhan diatom, berkisar antara 1,75-35,33% (17,75 ± 9,59%) relatif terhadap kontrol, dengan nilai penghambatan tertinggi di muara Sungai Cengkareng (M2). Hubungan antara konsentrasi kontaminan dan respon penghambatan tidak dapat dijelaskan dengan lebih pasti namun terdapat asumsi konsentrasi rendah dari beberapa logam berat diduga memberikan efek buruk pada pertumbuhan diatom.Kata Kunci: sedimen, toksisitas, diatom laut, Chaetoceros gracilis, Teluk Jakarta
