(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]). -

TIRTANINGTYAS¹ & KHALEB YORDAN² ¹ Burung Laut Indonesia, Depok, East Java 16421, Indonesia ([email protected]) ² Jakarta Birder, Jl. Betung 1/161, Pondok Bambu, East Jakarta 13430, Indonesia Received 17 August 2016, accepted 20 October 2016 ABSTRACT TIRTANINGTYAS, F.N. & YORDAN, K. 2017. Updating the seabird fauna of Jakarta Bay, Indonesia. Marine Ornithology 45: 11–16. Jakarta Bay, with an area of about 490 km2, is located at the edge of the Sunda Straits between Java and Sumatra, positioned on the Java coast between the capes of Tanjung Pasir in the west and Tanjung Karawang in the east. Its marine avifauna has been little studied. The ecology of the area is under threat owing to 1) Jakarta’s Governor Regulation No. 121/2012 zoning the northern coastal area of Jakarta for development through the creation of new islands or reclamation; 2) the condition of Jakarta’s rivers, which are becoming more heavily polluted from increasing domestic and industrial waste flowing into the bay; and 3) other factors such as incidental take. Because of these factors, it is useful to update knowledge of the seabird fauna of Jakarta Bay, part of the East Asian–Australasian Flyway. In 2011–2014 we conducted surveys to quantify seabird occurrence in the area. We identified 18 seabird species, 13 of which were new records for Jakarta Bay; more detailed information is presented for Christmas Island Frigatebird Fregata andrewsi. To better protect Jakarta Bay and its wildlife, regular monitoring is strongly recommended, and such monitoring is best conducted in cooperation with the staff of local government, local people, local non-governmental organization personnel and birdwatchers. -

Two vessels of a domestic shipping line appear to have served as a transport vector for the Asian green mussel Perna viridis (Linnaeus, 1758) between regions. This species is indigenous in the western but not in the eastern part of the archipelago, separated historically by the Sunda Shelf. The green mussels collected from the hulls of the ferries when in eastern Indonesia showed a significantly lower body condition index than similar-sized individuals from three different western-Indonesian mussel populations. This was presumably due to reduced food supply during the ships’ voyages. Although this transport- induced food shortage may initially limit the invasive potential (through reduced reproductive rates) of the translocated individuals, the risk that the species will extend its distributional range further into eastern Indonesia is high. -
Heavy Metal Concentration in Water, Sediment, and Pterygoplichthys Pardalis in the Ciliwung River, Indonesia 1Dewi Elfidasari, 1Laksmi N
Heavy metal concentration in water, sediment, and Pterygoplichthys pardalis in the Ciliwung River, Indonesia 1Dewi Elfidasari, 1Laksmi N. Ismi, 2Irawan Sugoro 1 Department of Biology, Faculty of Science and Technology University Al Azhar Indonesia, Jakarta, Indonesia; 2 The Center of Isotope and Radiation Application (PAIR), The National Agency of Nuclear Energy (BATAN), Jakarta, Indonesia. Corresponding author: D. Elfidasari, [email protected] Abstract. Ciliwung River is one of the most polluted freshwaters in Indonesia, shown by its color, smell, and the wastes. Generally, the presence of heavy metals is an indicator of pollution in any river. Furthermore, the survival of waters biota is determined by the pollution levels of the water and sediment, including the Pterygoplichthys pardalis fish dominating the river. The purpose of this study therefore was to record the concentration of heavy metals in water, sediment, and P. pardalis in the Ciliwung River from upstream in Bogor to its downstream in Jakarta. The X-Ray Fluorescence (XRF) spectrometer was used to analyze the metals. The results showed that the concentrations of heavy metals such as Cd, Hg, and Pb were relatively high in the water and sediment of the river, exceeding the threshold of Indonesian Government Regulation. The highest concentration of these metals was found in the samples from Ciliwung River Jakarta area. The concentrations of these metals were quite high in the P. pardalis flesh exceeding the threshold set through the provisions of National Agency of Drug and Food Control (BPOM) and Indonesia National Standard (SNI). On analysis, there was a strong correlation between the metal content of fish flesh and sediment. -
An Analysis of Water Security Issues in Jakarta City, Indonesia Destinee Penney & Mandie Yantha
A Megacity’s Hydrological Risk: An analysis of water security issues in Jakarta City, Indonesia Destinee Penney & Mandie Yantha [email protected] (corresponding author) MDP Student, University of Waterloo Abstract Water is the most important and arguably the most crucial resource on the planet. As it is the necessity for life, the need to improve sustainability and reduce the scarcity of water around the globe, while ensuring equal access and quality is imperative for the survival of millions of individuals. Overpopulation, overconsumption, and globalization continues to increase the demand for the resource. Efforts to achieve global water sustainability and security will fail if appropriate sustainable management methods and practices are not addressed and implemented. This paper examines water security in the megacity of Jakarta, Indonesia. Research outcomes indicate that water security in Jakarta City is impacted by inadequate infrastructure, unequal use by a growing population, and inadequate governance structures. It is important to identify water security issues to achieve sustainable, safe, and affordable access for all current and future users. To address the water security issues in Jakarta, it is being recommended that effective and good governance strategies be implemented within Jakarta’s social, political, and economic structures with the investment of adequate infrastructure and management systems, the improvement of integrated water resource management (IWRM), the adoption, alignment and enactment of the New Agenda and National Action Plan principles, in addition to the improvement of education, public awareness, and collaboration of all stakeholders. These recommendations are both essential and vital if Jakarta wishes to meet growing water security demands.

Major Sources and Monthly Variations in the Release of Land-Derived
www.nature.com/scientificreports OPEN Major sources and monthly variations in the release of land- derived marine debris from the Greater Jakarta area, Indonesia Muhammad Reza Cordova * & Intan Suci Nurhati As marine debris becomes increasingly prevalent and induces cascading impacts on marine ecosystems, monitoring of land-derived debris is key for identifying efective mitigation strategies. Indonesia plays a pivotal role in reducing land-derived debris into the oceans considering its extensive coastline, large population and high waste production. We present the frst marine debris monitoring data from Indonesia’s capital, the Greater Jakarta area, by characterizing major sources and monthly variations of debris release at nine river outlets into Jakarta Bay between June 2015-June 2016. Our data show plastics as the most common debris entering Jakarta Bay representing 59% (abundance) or 37% (weight) of the total collected debris. Styrofoam was dominating among plastic debris, highlighting the urgency of reducing plastic and styrofoam uses. Higher debris releases during the rainy season (December-February) highlight the need to intensify river clean-up activities. We estimated an average daily debris release of 97,098 ± 28,932 items or 23 ± 7.10 tons into Jakarta Bay with considerably lower inputs from the capital compared to its neighboring municipalities. Within the plastics category, feld monitoring data yield a daily plastic debris release of 8.32 ± 2.44 tons from the Greater Jakarta area, which is 8–16 times less than global-scale model estimates. Te presence of marine debris − a persistent, solid discarded waste in the marine environment, is pervasive in beaches, coastal waters and open oceans mainly due to land-based human activities. -
Water Quality in Three Reservoirs on the Citarum River, Indonesia
WATER QUALITY IN THREE RESERVOIRS ON THE CITARUM RIVER, INDONESIA Simon Sembiring * *Reseacher, Research Institute for Water Resources Development Jl. Ir. H. Juanda No. 193 Bandung – 40135, Indonesia Fax : + 62-22-2500163 ABSTRACT Three large reservoirs have been built on the Citarum River in West Java over the last two decades. Saguling (completed 1985), Cirata (1988) and Jatiluhur (1967) are the first, second and third reservoirs respectively downstream from Bandung city. Saguling and Cirata were built primarily for hydroelectric power and Jatiluhur primarily for rice irrigation. Subsequently all three are used for industrial, domestic, fisheries, recreation and transportation purposes. Jakarta city, about 130km from Jatiluhur, plans to use the water from this reservoir as its main water supply. It has been known for more than a decade that the water of all three reservoirs is polluted by inflows of domestic sewage, industrial and agricultural wastes. In addition, considerable organic pollution comes from fish farming in the reservoirs. In year 1998 Saguling had 2500 floating cage nets, Cirata 2700, Jatiluhur 720 . A number of pollutants exceed the limits of the official water quality regulation standards of the government of Indonesia, particularly dissolved oxygen, zinc and iron. This paper give some updated information about the level of pollution. Unless the sources of pollution are controlled the effects of it presently seen in macrophyte plant infestation, algal blooms, fish kills and degradation of potable and industrial water will increase. KEYWORDS: Citarum , reservoir ,Cirata, Jatiluhur,Saguling, pollution, water quality. INTRODUCTION The Citarum is one of the main rivers in Indonesia, with a length of about 315km.
