Abstract

Cimanuk is one of considerable potential river in West Java besides the Citarum River and Citanduy. Associated with the use of river water as raw water Cimanuk for various uses, needs to be monitoring thewater quality conditions continuously. Cimanuk water quality assessment conducted to determine compliance with its allocation, state of water quality status and trends of water quality changes from time to time. The research method involves sampling, measurement of field parameters, testing the water quality in the laboratory, evaluation and assessment of water quality conditions. Based on water quality data during the period of years 20052009, showed that the characteristic Cimanuk water quality is better. This can be seen from the level of freshness still meet water quality criteria with dissolved oxygen content greater than 3 mg/L. Potential of Cimanuk water quality in the rainy season is the Class I of Government Regulation no. 82/2001 (water that can be used for various uses), Class III and Class IV i n the dry season. Assessment of water quality status were calculated using STORET method. If the assessment carried out on B,C,D Class ofState Java Governor no. 38/1991, Cimanuk River conditions are "lightly polluted" upstream and "medium polluted" in the downstream. When using the classification of Class I Government Regulation no. 82/2001, then the condition is "medium polluted" upstream and "heavily polluted" in the downstream. When using Class II, the condition is "medium polluted" in upstream to the downstream.

Abstract

River water quality at various places in Indonesia continues to decline due to pollution by domestic, industrial, and agriculture waste. The Pollutant Index of Solo River is showing conditions from “lightly polluted” to “medium polluted”. These conditions cause the river water quality to be no longer appropriate to its designation. This study aims to assess the level of water pollution of the Solo River using the chemical-physical index. By knowing the level of water pollution, the water resources management can prioritize certain sections for improved water quality, so that it can be developed as a source of raw water for a variety of purposes. The chemical-physical index can be limited to one data measurement (grab sampling data), so its use may be another alternative to rapid determination of water pollution level (WPL). The WPL in the Solo River is “very lightly polluted” to “lightly polluted” during the rainy season, but during the dry season varies greatly. The WPL of the Solo River from upstream to downstream in the period 1995 was identified from “lightly polluted” to “critically polluted” and from, “lightly polluted” to “very heavy polluted” in the period 2002-2011. Decline in water quality had significantly increased as was observed by the rising WPL value in the upstream segment during the period 2006 to 2011.
