| dc.description.abstract | The most important stage for managing an irrigation system is
irrigation water requirements. The research aims to obtain the
amount of irrigation water required for the Kedunggupit Kulon
Irrigation Area (DI) and to evaluate the balance between
demand discharge and water availability discharge. The data
used for water availability is Kedunggupit Kulon Dam intake
data and Wadaslintang Reservoir supply discharge for 4 years,
namely from 2019-2022, then calculating water needs requires
data on percolation, water needs for plant consumption, water
layer replacement and effective rainfall. The results of this
research were obtained in 3 periods, namely from 2019-2020,
2020-2021, and 2022-2023. It seems that irrigation water needs
have not reached a good balance. Water availability in August,
September and October or in the third growing season
(palawija). The dam and supplement intake were observed to be
completely unable to supply water because the intake at the
Kedung Gupit Kulon weir and the supplement intake from the
Wadaslintang Reservoir were closed for maintenance of the
irrigation network. Because MT III, namely secondary crops,
does not require too much water, another alternative is for
farmers to use ground wells at several points in the rice fields or
fields, apart from that, farmers also utilize the remaining
drainage using water pumps to distribute it to the rice fields. | en_US |
