Studi Perencanaan Jaringan Irigasi Daerah Irigasi Pitab Kabupaten Balangan Provinsi Kalimantan Selatan

The aims of irrigation network planning is to determine the mainstay of irrigation water needs, cropping planning patterns, as well as the discharge needed for agricultural areas. Indonesia itself isan agrarian country so it is natural that the first priority in the national development agenda iscentered in agriculture. Based on that, the availability of agricultural diarrhea water is one of theguarantees of food availability to increase national food production. So that the success of rice selfsufficiencyinordertoimprovefoodsecuritycannotbeseparatedfromtheroleofwater.Variousattemptshave been made to increase the yield of food production, including the opening ofagricultural land. In Balangan Regency, South Kalimantan Province, especially Awayan District,has the potential of water resources and the potential of undeveloped agricultural land. Therefore, inan effort to improve and meet the food storage needs of the Balangan Regency, the BalanganRegency Water Works Public Works Department plans to carry out the planning work of the 4000hectare pitap irrigation area to serve the technical irrigation plan area. This is done so that thedevelopment of irrigation networks in locations can be optimally and sustainably well, so that it istechnically feasible, economically, and environmentally. In writing this final project, which isplanning the rebuilding of pitap irrigation networks in the awayan sub-district so that all sub-districtscan be irrigated properly. So that the final results obtained are the mainstay discharge with areliability of 80% that is 112.5 m3 / sec and the magnitude of the mainstay discharge with a reliabilityof a percentage of 20% is 185.41 m3 / sec. And from the plan of calculating the alternative 2 croppingpatterns with the rice-palawija cropping pattern, the water requirement in the paddy field (NFR)used is 13.3772 lt / sec / ha.
