Analisa Efisiensi Dan Kehilangan Air Pada Saluran Tersier -2 Daerah Irigasi Simandolak -2 Desa Rawang Binjai, Kecamatan Pangean, Kabupaten Kuantan Singingi
ABSTRACT
The purpose of this study was to analyze the amount of water loss and the value of
irrigation efficiency that occured in the Tertiary -2 Channel of the Simandolak -2
Irrigation Area without taking into account the process of water loss. The water loss
was analyzed using the inflow – outflow method. The data needed in this research
is primary data in the form of water velocity, water depth, and water surface width.
In addition, secondary data is also used in the form of building schemes and
irrigation networks, as well as a map of the location of irrigation areas obtained
from the Sumatra River Region III. From the calcution analysis, it was found that
the value of water loss due to evaporation was not too significant. Meanwhile, based
on measurements made for 15 days, it was obtained that the analysis of the overall
calculation of water loss in the tertiary channel with a percenage of 38,5 % and the
efficiency valu of the tertiary channel of 61,5 %.
