PERENCANAAN JARINGAN IRIGRASI DAERAH BAKALAN GAJAH KABUPATEN MUARA

The Planning of Irrigation Network at Bakalan Gajah Area Muara Enim Regency The final report is about the planning of irrigation network at Bakalan Gajah area Muara Enim regency. This report discusses the planning and calculation of the dimensions of the secondary line SSBGKi 1 until SSBGKa 4 with a total channel length of 5806,52 m. In addition to planning, there are 9 tertiary channels. 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 secondary channel for SPSB 10 ( b : h = 1 : 1, v = 0,3 m/det , I = 0.00258, L = 412 m ), SPSB 9 ( b : h = 1 : 1, v = 0,3 m/det , I = 0.00116, L = 466 m ), SPSB 8 ( b : h = 1 : 2, v = 0,3 m/det , I = 0.00208, L = 430 m ), SPSB 7 ( b : h = 1 : 1.5, v = 0,3 m/det , I = 0.00159, L = 407 m ), SPSG 6 ( b : h = 1 : 1.5, v = 0,3 m/det , I = 0.00087, L = 1073 m ), SPSG 5 ( b : h = 1 : 2, v = 0,3 m/det , I = 0.00079, L = 1073 m ), SPSM 4 ( b : h = 1.5 : 2, v = 0,3 m/det , I = 0.00072, L = 883 m ), SPSM 3 ( b : h = 2 : 2, v = 0,3 m/det , I = 0.0050, L = 1602,5m ), SPSM 2 ( b : h = 2 : 2, v = 0,3 m/det , I = 0.00036, L = 1041 m ), SPSM 1 ( b : h = 1.5 : 2, v = 0,3 m/det , I = 0.00090, L = 99 m ). In implementing this project requires funding budget of Rp. Rp 12.517.651.022. Key words: Primary Channels, Irrigation, rata-rata Aljabar method
