Abstract
East Kalibaru River is one of the thirteen rivers flowing through Jakarta. East Kalibaru River has an important role in development of the region. Considering the increasing activities of people, settlements and number of industries along the East Kalibaru River, it is necessary to calculate contaminants load that discharged into the water body East Kalibaru. This study conducted to determine the point source and domestic waste pollution loads, using parameters of BOD, COD and TSS. The analysis showed that the total pollution loads such are calculated as 43.714 kg/day for BOD, 60.107 kg/day for COD and total 41.529 kg/day for TSS. Total pollution load discharged into river from point source effluent is amounted of 249 kg/day for BOD, 1.505 kg/day for COD and total 411 kg/day for TSS. Effect of domestic waste is very insignificant compared to the effect of point source that went into the river. The result suggest that approach that need to be done to reduce the burden of domestic waste water pollutants is by performing additional production or communal Wastewater Treatment Plant (WWTP) in densely populated areas.

Assessment of Point and Nonpoint Sources Pollution in Songhua River Basin, Northeast China by Using Revised Water Quality Model
Summary
Sumber pencemaran dapat dikategorikan dalam dua jenis, pencemaran point source dan non-point source. Kemampuan air untuk membersihkan diri secara alamiah dari berbagai kontaminan dan pencemar dikenal sebagai pemulihan diri atau self purification (Imholf, 1979). Air hujan yang jatuh di permukaan jalan dapat terkontaminasi dengan minyak mobil, debu, kotoran hewan, tanah, sedimen Di daerah perkotaan curah hujan sebagai run-off (aliran air permukaan) adalah salah satu sumber nonpoint source utama pencemaran yang dapat mempengaruhi kualitas air sungai. Pengaturan jumlah bahan pencemar yang dapat dibuang ke sungai didasarkan atas kajian ilmiah tentang daya tampung beban pencemaran pada sungai. Hal ini dilakukan untuk memastikan bahwa bahan pencemar yang dibuang ke sungai tidak melampaui kemampuan air sungai untuk membersihkan sendiri. Penelitian bertujuan untuk mengetahui nilai beban pencemaran point source dan limbah domestik dengan perhatian khusus pada parameter BOD, COD, TSS dengan melakukan perintegrasian dengan Geographic Information Systems (GIS) di sepanjang aliran sungai Kalibaru Timur
