Abstract

Water of the Riam Kanan reservoir is used for irrigation, the supply of raw water, fishery, and hydro-powered,and transportation, etc. Domestic activities of domestic , agriculture, livestock and gold mining gold in the catchment area of Riam Kanan and acitivity fishery activities in the reservoir could be may degrade its water quality .The objective of this research is to know find out more on the pollution potential from catchment area and fishery activity, the characteristics of water quality , the trophic status and stratification of Riam Kanan reservoir. The research was conducted in May, 2009 and August, 2009. The descriptive study method applied had collected secondary data and water samples for analysed analysis. Evaluation was done based on PP no 82/2001 (Government Regulation no 82/2001) and trophic status according to the criteria stated in KepMen LH No:28/2009. Research results on pollution emission potential in the Riam Kanan Reservoir comprised: total Nitrogen 488 kg/day, and total phosphate 158 kg /day, and BOD 3,394 kg/day respectively. The conclusion of It can be concluded that water quality in the Riam Kanan reservoir suitable is in conformity with the criteria of Class 1 (PP 82/2002). The trophic status throphic was identified in the range of mesotrophic - eutrophic or medium fertile. The Stratification of Riam Kanan reservoir is oligomictic.

Abstract

In order to find out the level of acid deposition especially in West Java's inland water aquatic, and inline with the active participation of the Research Center for Water Resources in the Network for AcidDeposition Monitoring in East Asia, a study was conducted on the degree of inland water aquatic acidity inLake Patengan from 1999 to 2007. This study was based on descriptive method, observations, includingthe collection of secondary data and field sampling and sample analysis in the laboratory of theExperimental Station for Water Resources Environment according to the 1996 compendium of IndonesianNational Standard (SNI), SNI 2004 and the Acid Deposition Monitoring Network in East Asia (EANET)2001. Results of study show that from 1999 until 2007, average pH value of each year had increased from 7.7to 8.3, but from 2002 up to 2007, average pH of water in Lake Patengan had decreased each year from 8.3 to7.8. In general, the ion balance is still good. From 1999 to 2007, pH in Patengan lake increased from 7.1to 8.4 with average 7.8 and standard deviation 0.3865. However, acid deposition was not identified by theinland water aquatic conditions at Situ Patengan, West Java , Indonesia.
