Kajian Status Pencemaran Sungai Batang Gangsal Indragiri Provinsi Riau

---

Along the banks of the Batang Gangsal River there are many tributaries
and ditches which have a major influence on the entry of pollutant sources from
various activities in the mainland, activities carried out by the community are
agricultural activities, coal mining and C excavation, land clearing and industries
that dump their waste into the waters. rivers and domestic waste from
anthropogenic activities as well as waste from transportation that passes through
the Batang Gangsal River.
The aim of this research was to determine the river water quality and
pollution index, the pollutant load entering the Batang Gangsal River and to see
the ability of the Batang Gangsal River to receive pollutant loads. The method
used in this study was direct observation in the field, laboratory analysis to test
water quality and in-depth interviews to analyze social and economic conditions.
The water quality conditions of the Batang Gangsal River from 8
parameters that have been analyzed include: temperature 270C-300C, TSS 26-
1172 mg/L, Ph 5.33-6.36, BOD 0.8-4.7 mg/L, Nitrate 0.4-1.4 mg/L, Total
phosphate 0.02-0.06 mg/L, Zn metal 0.01-0.15 mg/L and total coliform 13.0-3500
MPN/100 mL. The Batang Gangsal River receives pollutant loads in the order of
total P < metal Zn < Nitrate (NO3-N) < BOD5 < TSS. The Batang Gangsal River
is still capable of decomposing total BOD5, total phosphate and nitrate. While the
parameters of TSS and Zn metal have exceeded the assimilation capacity where
the amount of pollutant load is higher than the assimilation capacity. The
pollution index values of the Batang Gangsal River in the upstream, middle and
downstream sections have varied values, ranging from meeting the IP value of
0.61 (upstream) to being moderately polluted with an IP value of 5.67
(downstream).
The condition of the water quality of the Batang Gangsal River has
affected the social and economic changes of the people who live around the
Batang Gangsal River. If in the past many people used river water for their daily
needs, now it is only used by the community for water transportation. In addition,
the decline in water quality also causes a decrease in the income of fishermen in
the Batang Gangsal River, because the types of fish and shrimp that fishermen get
are getting less so that many fisherman choose to switch livelihoods to become
farmers.
