Abstract:
In the Pidie Regency area in general, there are still problems with its watershed (DAS), namely pollution due
to domestic and non-domestic waste disposal and illegal mining which is part of the population's activities
(anthropogenic) which continues to increase as a form of the population's efforts to meet their needs. In PIDIE
District the watershed consists of the Teunom River Watershed, the Baro River Watershed, and the Krueng
Baro River Watershed. With the increasing anthropogenic activity in the Watershed in PIDIE Regency,
especially in the Kreung Baro River Watershed, this indicates the need to take action through the
identification, mapping and assessment of the Watershed as an important effort to prevent further pollution
and decrease water quality and sedimentation. This study uses the Pollution Index (PI) method so that the
quality of water in the watershed will be easily controlled and in accordance with water quality standards and
in accordance with what has been set by the government. and the Sediment Quality Guidelines (SQGs)
method which can determine the appropriate levels in sediments in the watershed. The water quality of the
Krueng Baro River, Pidie Regency using the Pollutant Index (PI) method with a value of 3.8062 for drinking
water designation (class 1) is moderately polluted, different when compared to data obtained from the Aceh
Provincial Government in 2022 with a value 2.5496 classified as moderately polluted. The water for
agricultural purposes (class IV) with a value of 0.4569 is classified as fulfilling the water quality standard
requirements. Likewise, the data carried out by the Government of Aceh with a value of 0.2848 is classified
as fulfilling the water quality standard requirements for agriculture. Sediment quality in Krueng Baro, Pidie
Regency with data processing using the Sediment Quality Guidelines (SQGs) method with a value of 0.0002,
this value is the same as the value carried out by the Aceh Provincial Government, which is classified as a
moderate negative effect of heavy metals on biota. |
