Abstract

Planning a tertiary irrigation network in desa Jejawi, located in Kecamatan Jejawi Kabupaten Ogan Komering Ilir, is an effort to reduce the impact of floods and severe droughts experienced by farmers in desa Jejawi. The planning in this study uses primary data derived from field observation and secondary data in the form of rainfall data from the Giovanni satellite and climatological data from Kenten BMKG Station. This study uses two analysis, hydrology analysis that consists of Irrigation water demand (NFR), Discharge Modulus (Dm) and Planned Debit (Qt, Qd). While the hidraulic analysis consist of Tertiary Irrigation Channel Dimension Design. The results of channel planning are maximum NFR of 1,171 lt/sec/ha, Dm of 1.91lt/sec/ha, Qt ranging from 0.0148 m3/s to 0.0246 m3/s, Qd ranging from 0,026 m3/dt to 0,042 m3/s, with the design channel in the form of a double-function open-trapezoidal channel, with b ranging from 0.15 m to 0.2 m, h ranging from 0.23 m to 0.29 m, P ranging from 0.80 m to 1.01 m, w of 0.4 m and planned slope from 0.001042445 to 0.001388927.
