    (2013-06-20) Rahmi; Fauzi Manyuk; Sandhyavitri Ari
    Agriculture is an area that requires special attention, where food insecurity is often seen in Indonesia and the world at large. Food insecurity happen because agriculture is not handled well. Parameter optimalization is planned based on the decision-making system method of Analytical Hierarchy Process (AHP) which are : Technical, Economic, Environmental, and Social/Cultural. The results of the AHP analysis with the help of Expert Choice program 2000 found that the most influential criteria in optimizing the use of irrigation water is technical criteria. The percentage of some criteria are technical criteria 39.9%, economic criteria 36.0%, environmental criteria 15.9%, and the criteria of social/cultural 8.1%. In addition, sub-criteria that most affect the optimal use of irrigation water are the cost of development and rehabilitation work of irrigation channel, the performance of the channel, and cooperative farmer groups P3A, where the three sub-criteria above must be maintained well. While the sub-criteria which need to be improved are the presence of a water keeper, the availability of funds to finance the annual operation and maintenance of irrigation, as well as the condition and function of irrigation channel.
