"This book is designed to provide concepts, methodologies, and approaches for river basin studies with respect to water resources and environment. The book is not limited to the Yamuna River basin, but will help in the study of various other river basins for integrated water resources management. The book covers the essential components of integrated water resources management, including analysis of climatic variables, climate change detection, analysis of natural resources, geology, geomorphology, socio-economics, water budgeting, flood estimation, river pollution, etc. Furthermore, the book addresses recent issues pertaining to water quality, water quality indices, environmental flows, water resources management through cropping pattern change, etc. along with methodologies and application to the Yamuna River system. However, the main objective of this book is to address important issues of water resources management of river basins. "

"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 mempersyaratkan 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.

AbstractThis research is a part of a multidisciplinary research in the Angke River. The aim of this research is to study the river?s water quality from the microbiological point of view in several locations along the Angke River. The locations under this study included: Duri Kosambi, Pesing Poglar, Teluk Gong, Pantai Indah Kapuk and Estuary (4 points). The examinations were held in term of microbiological aspects, based on the guide published by the Ministry of Health, the Republic of Indonesia and concluded according to Government Regulation. The parameter of microbiological tests was the most probability number (MPN) of total and fecal coliform. The method used was done in 2 steps: presumptive and confirmed test. Completed test was conducted to confirm the presence of E.coli and other bacteria in water. The result showed that the water quality of the Angke River was poor; therefore, it is not recommended to be used as drinking water. It is categorized as the 2nd class quality that means it can only be used for water recreation, veterinary, showering plants and or other purposes that require the same quality of water. The MPN of total coliform at Pantai Indah Kapuk and the outer side of river mouth (estuary area) was lower than other areas. People who live in Pantai Indah Kapuk are having a higher economic level. Therefore, it can be assumed that they are more educated people who have more insight about hygiene. Further, the water at the outer side of river mouth contains a higher salt concentration that can kill pathogenic bacteria. In conclusion, the water quality of the Angke River is categorized as 2nd class quality not recommended to be used as dringking water except the water from Pantai Indah Kapuk and estuary area that can be used as dringking water after boiling."

"This project is motivated from environmental degradation and pollution problems caused by the outboard motors. Environmental and safety constraints are an increasingly necessity which enforces the demand for new technologies and development. Therefore, this research aims to provide velocity field data correlated to water quality measurements taken during the field tests and used to establish the effect from the outboard motor. Acoustic Doppler Velocimeter (ADV) is widely used for field measurement of two and three dimensional water velocity. The implementation of the ADV measurement technique is accomplished by measuring the phase change in the acoustic signal reflected of the scattering particles in the flow, than by looking at the data that the ADV gave I?ll be using a lot of statistical method in order to identify the outboard velocity signature, the are 9 statistical method that I?m going to use which is: One second average of mean velocity One second average of standard deviation One second average of resultant velocity One second average of skewness One second average of kurtosis One second average of angle of resultant velocity make with x axis Wavelet FFT One second average of Backscatter Intensity (BSI) After using all of the statistical analysis mention above, than I will identify the best statistical method in order to identify the outboard velocity signature. Further analysis will be done by looking at the changing value of mean velocity and backscatter intensity, this than will help to identify the behaviour of different types of outboard motor that used in this research."

"Fecal contamination is a serious environmental problem at Angke River Jakarta. A cross-sectional study was conductedduring April-June 2007 and the aim of the study is to assess the water quality of Angke River by detection of Ascarislumbricoides eggs and the protozoan cysts. A total 24 L water of Angke River was collected from 8 sampling locationsconsisted of Kembangan/Duri Kosambi (upper reaches of river), Pesing Polgar (lower reaches of river), Teluk Gong(lower reaches of river), Pantai Indah Kapuk (estuary), River Mouth, left side of River Mouth, right side of RiverMouth, and outer side of River Mouth. The water specimen was examined microscopically for A. lumbricoides eggs andprotozoan cysts using a concentrated technique. Of 8 locations, 4 locations (50 %, 4/8), Kembangan/Duri Kosambi,Teluk Gong, Pantai Indah Kapuk and left side of river mouth were positive for A. lumbricoides eggs and 2 locations(25%, 2/8), Kembangan/Duri Kosambi and Pesing Polgar positive for Entamoeba histolytica cysts. Overall, 60 A.lumbricoides eggs and 2 E. histolytica cysts were found in 24 L water specimens. Among sampling locations, the mostnumber of A. lumbricoides eggs were found at eastuary. The water of Angke River, Jakarta, has been contaminated byhuman feces contained A. lumbricoides eggs and E. histolytica cysts. The water was unsafe for drinking water."
