| Summary: | Mayo Swamp so far is used for irrigating the agriculture area of Kampung
Kurik II (Harapan Makmur), Kampung Kurik (Wonorejo) and Kampung Kurik I
(Rawasari). The benefit of Mayo Swamp water source is hoped to answer the
demand of water irrigation towards the potency of area�s width. Research is
needed to be conducted first in order to get the maximal benefit of the
accommodated water in Mayo Swamp for irrigation water supply area which of
width is 2038Ha.
In this research, some shifted schedule and planting pattern is done in
order to maximize the area potency and the available swamp water. The three
alternative which simulated based on the planting schedule include Alternative I
which is started in January, while Alternative II and Alternative III are started in
November and December with the planting pattern Rice plant-Rice plant-Seasonal
Plants. The best decided alternative is determined by using the method Analytical
Hierarchy Process (AHP) by considering the sufficiency factor which is
represented by the indicator of Relative Irrigation Supply (RIS), while efficiency
and effectiveness are represented by the efficiency system (Esistem) and planting
intensity (IT). The priority determination (the best alternative) is done by
choosing the biggest weight from the three planned alternatives.
Based on the method Analytical Hierarchy Process (AHP), the three
alternative are conducted by considering the planting schedule which refers to the
factor of area�s width, water efficiency, and planting intensity. The most ideal
planting schedule based on AHP has to be conducted in November. In the planting
width of the first alternative on MT-I, MT-II and MT III is 236 Ha, while on the
second and third alternative of planting width on MT-III (seasonal plants) are 50
Ha and 75 Ha. Referring to the second and third alternative then the planting
width of MT-I and MT-II are 316 Ha and 306 Ha. The pump which is used to
irrigate the farmers� rice fields includes 2 units of pump machines with the
capacity 0.75 m3/sec with the duration of optimal operation approximately 7
hours/day.
