STATUS MUTU DAERAH PENAMBANGAN PASIR DI PERAIRAN SUNGAI SERAYU DENGAN MENGGUNAKAN METODE STORET

Abstract

The quality of river water is strongly related to human activities in it. Changes
in the condition of water quality in the river flow are the effects of the discharge
from existing land use. One of them is sand mining activities along the Serayu
River, especially around Tumiyang, Kebasen, Banyumas Regency. Activities
from sand mining will cause a decrease in river water quality. From this activity,
it is necessary to study the status of water quality using the STORET method to
determine the quality of river water so that the river can be utilized in accordance
with the applicable designation.
The STORET method is one method for determining water quality data with
water quality standards in accordance with the appointment of Minister of
Environment Decree No.115 2003. This research is a quantitative descriptive
study to determine the water quality of the Serayu river in the sand of mining
areas precisely in Banyumas Regency. The parameters measured in this study
were measurements of Total Disolved Solid (TDS), temperature, pH, and
Electrical Conductivity. Determining the location of taking water using a
purposive sampling method.
Based on the results of data analysis using the Storet method and refers to the
quality standards of Government Regulation No.20 of 1990 Group D. Water
quality in Serayu River has a total score of 9 after sand mining. This shows the
quality status of the lightly polluted Serayu river (-1 to -10). But still in class B
and the river water quality level is still in good condition. There are temperature
parameters that exceed the threshold of 25 - 32oC, but the TDS, DHL and pH
parameters are still within the threshold of designation in Group D.
