(Pb) Pollution in the River Estuaries of Jakarta Bay
The Sustainable City IX, Vol. 2 1555 Analysis of lead (Pb) pollution in the river estuaries of Jakarta Bay M. Rumanta Universitas Terbuka, Indonesia Abstract The purpose of this study is to obtain information about the level of Pb in the sediment of the estuaries surrounding Jakarta Bay and to compare them. Samples were taken from 9 estuaries by using a grab sampler at three different location points – the left, right and the middle sides of the river. Then, samples were collected in one bottle sample and received drops of concentrated HNO3. The taking of samples was repeated three times. In addition, an in situ measurement of pH and temperature of samples was taken as proponent data. The Pb concentration of the river sediment was measured using an AAS flame in the laboratory of Balai Penelitian Tanah Bogor. Data was analyzed statistically (one way ANOVA and t-test student) by using SPSS-11.5 software. The results show that Pb concentration in the sediment of the estuaries surrounding Jakarta was quite high (20–336 µg/g). The sediment of Ciliwung River in the rainy season was the highest (336 µg/g). Pb concentration of sediment in the dry season was higher than that in the rainy season, except in Ciliwung River. It was concluded that all rivers flowing into Jakarta Bay make a significant contribution to the Pb pollution in Jakarta Bay, and the one with the largest contribution was Ciliwung River. Keywords: Pb, sediment, estuaries, dry season, rainy season, AAS flame. 1 Introduction Jakarta Bay (89 km of length) is formed as a result of the extension of Karawang Cape in the eastern region and Kait Cape in the western region into the Java Sea (Rositasari [1]). -

View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Wageningen University & Research Publications EVALUATION OF URBAN POLDER DRAINAGE SYSTEM PERFORMANCE IN JAKARTA CASE STUDY KELAPA GADING AREA By Kalmah 1), F.X. Suryadi 2) Bart Schultz 3) Abstract Kelapa Gading area is located in the plains of North Jakarta about 6 km from the coastline of Jakarta Bay. Kelapa Gading area covers 1288 ha it consists of three large compartments and next to that the Kodamar Unit separated system from Kelapa Gading excess water of the area is discharged to Sunter river and Pertukangan River. The area is regularly flooded, especially during the wet season. Kelapa Gading area is in particular facing flood problem since Jakarta __ the capital city of Indonesia __ became the primary growth machine of the nation. Among others, this has resulted in suburbanization in Jakarta’s neighbouring regions. Land subsidence, which occurs due to huge groundwater extraction, and climate change are also contributing to flooding problem due to hydrologic changes that alter the magnitude and frequency of peak flows and sea level rise. Four main objectives are the basis for this research. First is describing the existing urban drainage and flood protection systems in Kelapa Gading area and other satellite cities (JABODETABEK). Second is analysing the possible impacts of land subsidence and sea level rise on inundated area. Next are some measures that would have to be taken into consideration in order to reduce the flooded area and provide adequate urban drainage and flood protection especially when the impacts of land subsidence and sea level rise are taken into account. -

Water Quality of Angke River: Microbiological Point of View
82 Tjampakasari and Wahid Med J Indones Water quality of Angke River: Microbiological point of view Conny Riana Tjampakasari, Mardiastuti H Wahid Abstrak Penelitian ini merupakan bagian dari penelitian multidisiplin di Kali Angke. Tujuan dilakukannya penelitian ini adalah untuk mengetahui kualitas air sungai ditinjau dari aspek mikrobiologik di beberapa lokasi sepanjang Kali Angke. Lokasi yang diteliti meliputi: Duri Kosambi, Pesing Poglar, Teluk Gong, Pantai Indah Kapuk dan Muara (4 titik). Pemeriksaan dilakukan berdasarkan petunjuk standar Departemen Kesehatan, Republik Indonesia dan hasilnya disimpulkan sesuai Peraturan Pemerintah Republik Indonesia. Parameter yang digunakan dalam uji mikrobiologi adalah most probable number (MPN) dari total dan fecal coliform, yang dilakukan dalam 2 langkah: uji presumtif dan uji konfirmasi. Uji lengkap dilakukan untuk mengkonfirmasi adanya E.coli dan bakteri lain dalam air. Hasil yang didapat menunjukkan bahwa mutu air Kali Angke kurang baik dan tidak dianjurkan sebagai air minum. Berdasarkan parameter mikrobiologik, kualitas air sungai ini dikategorikan sebagai kelas 2 yang artinya hanya dapat digunakan untuk rekreasi air, pembudidayaan ikan air tawar, peternakan, mengairi pertanaman dan atau peruntukkan lain yang memper syaratkan mutu air yang sama dengan kegunaan tersebut. Most probable number dari total coliform di daerah Pantai Indah Kapuk dan bagian luar daerah Muara lebih rendah dari daerah lainnya. Masyarakat yang tinggal di Pantai Indah Kapuk memiliki tingkat ekonomi yang lebih tinggi, dengan demikian dapat diasumsikan bahwa masyarakat ini memiliki tingkat pendidikan yang lebih tinggi dan memiliki kesadaran tentang kebersihan lingkungan yang lebih baik. Selanjutnya, air di daerah paling luar dari Muara memiliki kadar garam yang tinggi sehingga dapat membunuh bakteri-bakteri patogen. Akhir kata, kualitas air di sepanjang Kali Angke adalah air kelas dua yang tidak layak minum kecuali di daerah Pantai Indah Kapuk dan Muara yang layak minum sesudah dididihkan. -
Metal Speciation in Sediment from Muara Angke, Jakarta Bay Using of BCR Sequential Extraction Procedure
ILMU KELAUTAN: Indonesian Journal of Marine Sciences March 2019 Vol 24(1):23-30 ISSN 0853-7291 Metal Speciation in Sediment from Muara Angke, Jakarta Bay Using of BCR Sequential Extraction Procedure Lestari* and Fitri Budiyanto Research Centre for Oceanography, Indonesia Institute of Science Jl. Pasir Putih I Ancol Timur Jakarta Utara 14430, Indonesia Email: [email protected] Abstract The assessment of the biological availability of metals is rarely used only by knowing the total concentration of the metal. Therefore, six sediment samples from Muara Angke, Teluk Jakarta were assessed the chemical speciation of heavy metals. This study aims to determine metal speciation using the BCR sequential extraction procedure and to determine metal speciation to evaluate bioavailability in the sediments of Muara Angke, Jakarta Bay. In sediment from Muara Angke, the ability to move sequence of heavy metals studied was Pb>Zn>Cu>Ni. The mostly accumulated in the non-residual fraction of the total concentrations are Cu, Ni, Pb and Zn which indicated that the mobility and anthropogenic inputs of these metals in Muara Angke were quite high. The Risk Assessment Code (RAC) reveal that Zn and Ni at almost station exist in exchangeable and a fraction of carbonate-bound and therefore high-risk category. Most of the Cu at most of the station is in the oxidizable fraction, except a small portion found at all station is in the exchangeable fraction and fraction of carbonate-bound thus posing a low risk for the waters environment. The patterns of Pb speciation show no to low risk to the waters environment. -
Numerical Simulation of Cohesive Sediment Transport in Jakarta Bay
International Journal of Remote Sensing and Earth Sciences Vol. 6: 65-76 (2009) © IReSES NUMERICAL SIMULATION OF COHESIVE SEDIMENT TRANSPORT IN JAKARTA BAY I. M. Radjawane1 And F. Riandini2 Abstract. The 3D-numerical model has been applied to simulate the current circulation and cohesive sediment transport in the Jakarta Bay, Indonesia. Sediment load comes from 3 river mouths i.e. Angke River, Karang River, and Ancol River. The model was simulated to analyze the effect of tidal current and river discharge. A constant westerly and easterly wind was used as input of the model to see the influence of monsoonal season. The numerical results showed that the tidal current flows from east to western part of the bay during ebb tide and vice versa during flood tide. The surface current circulation was dominantly influenced by the tidal current compared with the wind and river discharge effects. High turbidity level was found near the river mouths with the range of 50 to 100 mg/l. This high sediment concentration was caused by the effect of sediment load from the river upstream. In the offshore area of the bay the sediment concentration decreases up to 10 mg/l. The movement of sediments followed the current circulations. During the flood tide, the sediment concentration from the mouth of Angke River moved to the western part of the bay. Model simulated for increasing the river discharge into two times showed that the sediment distributed to the offshore direction two times longer compare with the normal debit. The transport of sediment from the Angke and Karang Rivers to the offshore area reached > 6 km, while it just reached + 2,5 km from the Ancol River . -
Development Characteristics of a Coastal Slum Area in Indonesia: a Case Study of Fishermen Settlements in Muara Angke, North Jakarta
LIFEWAYS 37 International Journal of Society, Development and Environment in the Developing World Volume 3, Issue 1, April 2019 (37-54) Development Characteristics of a Coastal Slum Area in Indonesia: A Case Study of Fishermen Settlements in Muara Angke, North Jakarta RATNAWATI YUNI SURYANDARI1, LAILI FUJI WIDYAWATI1 1Department Urban and Regional Planning, Esa Unggul University, Jakarta, Indonesia Correspondence: Ratnawati Yuni Suryandari (email: [email protected]) Abstract As a fast developing and urbanizing country, the problem of slums those unplanned and unorganized settlements - does not only hit big cities, but almost every region in Indonesia. One such example can be found in the coastal areas of– Muara Angke, a fishing settlement area located in North Jakarta. This study identifies and analyses the characteristics of slum areas in Muara Angke based on seven physical criteria, namely, buildings, roads, drinking water, drainage, waste, garbage and fire protection. Primary data were obtained from a questionnaire survey of 70 local respondents supplemented by field observations. Secondary data were gathered from published and unpublished documents. Results of the study revealed that improvements of living conditions in the fishing slum village of Muara Angke were at moderate-to-very high levels. While buildings in the Muara Angke slums were of irregular quality, the quality of the fire protection service in the slums was moderately low. By contrast, the scores for building density was high as was the supply of drinking water and the provision of local drainage. In terms of environmental quality in the slums, road conditions, waste water management and solid waste management received very high scores. -

2016 Field Report Tracking Jakarta’S Waters
FreshWaterWatch 2016 FIELD REPORT TRACKING JAKARTA’S WATERS Ir Hendri Sosiawan We are very grateful for your care, let’s keep on training citizen scientists, collecting water samples Dear Citizen Science Leaders, and continue our efforts to disseminate knowledge We really appreciate your enthusiasm and about the importance of caring for water. Together commitment. we can secure a significant step in sustaining water availability and quality. You have put your Citizen Science Leader training in the classroom and in the field to practice by Ir Hendri Sosiawan collecting many water samples along the Ciliwung Agroclimate and Hydrology Research Institute River. REPORT FIELD You all are the ambassadors who care about the environment, especially the river ecosystem. This ecosystem is particularly vulnerable to pollution. You are all environmental researchers. Your commitment, passion and concern for the quality of the river water is admirable, thank you! Amazon Riverboat Exploration—2012 1 HIGHLIGHTS The highest concentration of nitrate and phosphate in the Ciliwung River is found during the dry season (July-October) and when the agricultural practices for vegetable crops is very intensive. We have found that the fluctuations of nitrate and phosphate concentrations in Ciliwung river are not only influenced by agriculture practices, but also depend on rainwater discharge during the rainy season or dry season. In a tropical country like Indonesia the water river discharge is significantly different between the rainy and dry seasons. So the abundance of nitrate and phosphate in the water during the rainy season was diluted by increased rainwater discharging into the river, even though the agricultural practices along Ciliwung river were at their peak.
