| Summary: | Water is essential in the agriculture sector; its quality and management contribute
to better harvest yield, regional economy, and social wellbeing. However, several
substances used in agriculture like fertilizers are detrimental to the environment if
utilized excessively. At the agriculture-focused village Lebakmuncang located at
Bandung Regency, the water used for irrigation is studied to evaluate the influence
of fertilizers on its quality as it travels down the agriculture fields. Twelve samples
of water are taken along six sampling points of the field’s tertiary irrigation channel.
These samples are examined for nine water quality parameters: temperature, pH,
TDS (Total Dissolved Solids), COD (Chemical Oxygen Demand), total phosphate,
total nitrogen, nitrite, nitrate, and ammonium. The results are then compared with
two water quality standards: Class 2 (Government Regulation 22/2021) and
Excellent (Water Resources Research and Development Center). The result of the
analysis shows that not only does the concentration of COD, total phosphate, total
nitrogen, and nitrite exceed at least one of the standards, but the pollution occurring
in the irrigation water is moderate in severity according to the calculated pollution indexes.
