PERENCANAAN JARINGAN IRIGASI AIR GILAS KABUPATEN OKU TIMUR PROVINSI SUMATERA SELATAN

The final report is about the planning of irrigation network at Air Gilas area East Oku regency. This report discusses the planning and calculation of the dimensions of the primary line SPG with a total channel length of 410 m and secondary line SSG1KI until SSG4AKI with a total channel length of 2628 m. The planning of the irrigation network is planned to meet or support the food production and food production is increasing. Planning data for the writing of this final report includes rainfall data, map, and others. The method used is the method of rata-rata Aljabar and methods Penmann and others. Based on calculations derived dimensions of each trapezoid-shaped primary channel for SPG ( b : h = 1 : 2, v = 0,50 m/det , I = 0,00050612 L = 410 m ), SSG1KI ( b : h = 1 : 2, v = 0,50 m/det , I = 0,00046949 L = 567 m ), SSG2AKI ( b : h = 1 : 2, v = 0,40 m/det , I = 0,00030256 L = 826 m ), SSG2KI ( b : h = 1 : 2, v = 0,50 m/det , I = 0,00057405 L = 329 m ), SSG3KI ( b : h = 1 : 2, v = 0,50 m/det , I = 0,00049247 L = 395 m ), SSG4AKI ( b : h = 1 : 2, v = 0,45 m/det , I = 0,00036447 L = 808 m). In implementing this project requires funding budget of Rp13.933.480.000,00. Key words: Irrigation, Air Gilas,Aljabar method
