Sekampung Batanghari Irrigation Area is included in Sekampung Irrigation System located in Lampung Province, Indonesia. The irrigation system is classified as technical irrigation network which one of the indicators is permanent headworks and supporting irrigation structures. Sekampung irrigation system is in national priority as this area provides the most paddy rice for Lampung province. The irrigation performance of Sekampung irrigation system including Sekampung Batanghari Irrigation Area impacts on food security for this province and the country in general. This study aims to investigate the irrigation performance of Sekampung Irrigation System based on the canal density, structure density, complexities of canal section and canal length and gate coefficient. Research method includes calibrations of irrigation gates and collecting secondary data about network density and network complexity. Result of this study show that the densities of canal and structures are insufficient in some networks. The complexities of canal sections are insufficient for all networks. On the other hand, the complexities of canal lengths are sufficient for all networks. The gates perform good water delivery during the calibration experiments. Some recommendations to improve the irrigation performance can be addressed such as improving network density and network complexity in order get the irrigation water distributed efficiently and uniformly until the tertiary and quaternary canals.
