(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]). -

Seeing the importance of water quality because it is the only source of mineral water Bengkulu city in which the water flowing from the fountain in Central Bengkulu Regency. Context territory that includes two administration (city of Bengkulu and Central Bengkulu District) causing the water quality is not controlled and there is no valid data for data management of the waters of the river basin. So, the purpose of this study to analysis the quality of river water in the river watershed segmentation Bengkulu. In order to obtain the level of water quality and water pollution index of a river that became a trend among regions and be detail data for watershed management policies. This study was conducted to test the water quality of the physical parameters, chemical and biological by comparing the results of laboratory tests of water quality 2 seasons. This method is very good for being able to analyze and describe the trend of changes in water quality in the watershed Bengkulu. Data obtained from secondary data and primary data. -

The structures of 1a and 1b were elucidated by extensive 1D and 2D NMR spectroscopy and confirmed by mass spectrometry. β-amyrin and α-amyrin were also obtained as the major constituents of the resin. Keywords: Canarium asperum , Burseraceae, asperol a, asperol b, β-amyrin, α-amyrin _____________________________________________________________________________________________ INTRODUCTION Canarium asperum subsp. asperum var. asperum Leenh. (Burseraceae) constitutes a highly polymorphous variety of the species that is endemic in the Malesian region, where it grows apparently well both in the primary and secondary forests or even in savannahs but mainly at low altitudes [1]. -
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. -

Using Grindle model (1980), we analyzed the performance of the policy and figure out its supporting and constraining factors. As a result, in general, implementation of decentralized water resources management based on “Integrated Water Resource Management (IWRM)” principles at Cisadane river basin has been running well. Nevertheless, some problems related communication among stakeholders, public participation, and limited resources are the main issues of decentralized water resources management in Indonesia and can hamper the policy to reach its goals.

Biodiversitas 17: 832-846. Bawean Island which located between Borneo and Java islands possessed unique and distinctive abiotic and biotic resources. Botanical survey has been conducted in Bawean Island Nature Reserve. This paper reported the results of inventory study of plant bioresources in 13 montane forests of Bawean Island, discussed their conservation status, bioprospecting on some wild plant species and potential development subjected to some conservation areas. Inventory results in montane forests showed that it was registered about 432 plant species under 286 genera and 103 families; comprised of 14 growth habits in which tree plants were the most dominant with about 237 species. Conservation status evaluation showed that there are at least 33 species of plants included in IUCN list comprised of 30 species categorized as least concern and 3 species considered at higher risk of extinction i.e. -

First print: July 2007 For copies write to: Forest Resources Officer FAO Regional Office for Asia and the Pacific Maliwan Mansion Phra Atit Road, Bangkok 10200 Thailand E-mail: [email protected] ii FOREWORDS Large extents of the coastlines of Southeast Asian countries were once covered by thick mangrove forests. In the past few decades, however, these mangrove forests have been largely degraded and destroyed during the process of development. The negative environmental and socio-economic impacts on mangrove ecosystems have led many government and non- government agencies, together with civil societies, to launch mangrove conservation and rehabilitation programmes, especially during the 1990s. In the course of such activities, programme staff have faced continual difficulties in identifying plant species growing in the field. Despite a wide availability of mangrove guidebooks in Southeast Asia, none of these sufficiently cover species that, though often associated with mangroves, are not confined to this habitat. -
