Abstract

The Brantas Generating Unit operates 13 Hydro Power Plants (PLTA) along the Konto River and the Brantas River. This study aims to see the effect and impact of the hydroelectric power generation unit on river quality in terms of Biological Oxygen Demand (BOD), oil and fat, and phenol levels. Sampling was carried out at the intakes and outlets of 10 hydroelectric power generation units along the Brantas River. From the research results obtained that the levels of BOD, oil and fat, and phenol levels have decreased in most of the hydroelectric power generation units in the Brantas River in East Java. The average reduction in BOD content was about 50%, the average reduction in oil and grease content was around 29%, and the average decrease in phenol content was around 44%. From the data obtained, it can be concluded that the existence of a hydroelectric power generation unit has a positive impact on the quality of river water used.
