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

Amphipods inhabit many marine benthic habitats and have an important ecological role. However, there is a lack of information about Indonesian amphipod diversity and distribution, especially in the shallow subtidal sediments of Probolinggo and Tangerang. During the transition to the monsoon season in September 2014, eight subtidal stations were sampled in Bayeman (Probolinggo) on East Java and seven subtidal stations were sampled in Kramat Kebo (Tangerang) in West Java. A total of 7346 amphipods individuals were collected, comprising five genera. Genus Photis was the most abundant group, followed by Grandidierella and Synchelidium. Multivariate analyses of these data indicated that sampling location and sediment granulometry were major determinants of distribution and composition of amphipods in Probolinggo and Tangerang.

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

Abstract

FACTORS THAT AFFECTING THE TOXICITY OF POLLUTANTS TO AQUATIC ORGANISMS. There are a large number of pollutants in aquatic environment with various characteristics and factors that can modify and affect the toxicity of pollutants in this environment. The major factors affecting pollutant toxicity include physicochemical properties of pollutants, mode of exposure, time, environmental factors, and biological factors. Moreover, organisms in an aquatic ecosystem are seldom exposed to only single pollutant, and most cases the stress of pollution on aquatic ecosystems is related to the interaction and combined effects of many chemicals. The combined effects may be synergistic or antagonistic, depending on the pollutants and the physiological condition of the organism involved.

Abstract

Rapid developments of industry and population growth have lead to ecological pressures on coastal areas. Semarang as capital of Central Java and port city, has an environment sensitivity which is important to be investigated. Sediment is an important part in aquatic environment because acts as sink or source of pollutant and could be used to assess coastal environment health. Three locations had been studied, i.e. Tanjung Mas Port, estuaries of Banjirkanal Barat and Banjirkanal Timur. These locations were compared to assess their health of sediment through elutriate sediment toxicity test. Eighteen grams of sediment from each locations were weighed and placed in 1 L Beaker glass.  Eggs and sperm are taken from spawning of adult green mussel in laboratory.  Thirty mL of sperm was added to the eggs and fertilized eggs were observed microscopically. Fertilized eggs were exposure to elutriate water-sediment from each location for 48 hour. Statistical analysis showed that there are significantly different abnormalities larvae percentage of sites 5, 8 and 13. The highest percentage of abnormality larvae occurred in Port Tanjung Mas, followed by Banjirkanal Timur and Banjirkanal Barat. Lead concentrations in sediments of coastal Semarang was ranged from 10.9 to 15.62 mg.kg-1, with an average of 13.69 mg.kg-1. Lead concentration was decreased form Port, Banjirkanal Timur and Banjirkanal, respectively. The abnormalities of green mussel larva may related to lead contamination. It could be concluded that sediment quality in Port area was very poor compare than other site. Keywords: bioassay, green mussel larvae, sediment, Semarang coastal area
