dc.description.abstract | Recently, agricultural production in the Sampean Baru Irrigation
area has not shown optimal cropping production. The average
percentage of planted areas in the first (November-February),
second (March-June), and third (July-October) planting seasons
for the upstream area was 93.67%; 98.02%, and 76.76%, and for
the downstream area was 83.54%; 80.81%; and 89.36%. This
research aims to optimize the water distribution system based on
the calculation of water requirements for plants and the
availability of channels to obtain the maximum planting area
and amount of agricultural production. This optimization
method uses a Dynamic Program with three scenarios. The first
scenario is the dry season. The second scenario is a normal
season. The third season is the wet season. This calculation is
based on effective rainfall, crop water requirements, and water
discharge availability. The percentage of the planted area
obtained from the dry year calculation for the first, second, and
third planting seasons, respectively, were 100%, 100%, and
90.36%. Based on the existing condition, the potential profit
obtained for a year is IDR 170.08 billion. After optimization
using Dynamic Program, potential profits in the dry year,
normal year, and wet year are IDR 213.52 billion, IDR 215.92
billion, and IDR 228.50 billion, respectively. | en_US |
