EVALUASI KINERJA JARINGAN IRIGASI BANJARAN UNTUK MENINGKATKAN EFEKTIFITAS DAN EFISIENSI PENGELOLAAN AIR IRIGASI

Abstract

Area Irrigation of Banjaran is Area Irrigation Technical wide of number three in of Banyumas Regency. Intake structure of Network Irrigation of Banjaran is on River of Banjaran. System Irrigation of Banjaran planned to irrigate agriculture area in four Districts residing in Banyumas regency that is District of West Purwokerto, South Purwokerto, Patikraja and Kalibagor. In his growth, it is believed have happened water insuffiency especially at in Banjaran downstream and dry season. Intention of research is to evaluate irrigation network performance of Banjaran in Banyumas regency to improve management of efficient and effective irrigation water. Analysis method the used is to study balance irrigate in intake structure in Banjaran, Ratio Comparison between planning discharge with network capacities discharge, and Ratio comparison between realize discharge with planning discharge. Difference of characteristic management of irrigation water done conducted perceived at upstream, middle, and downstream. Results of research indicate that, availability of banjaran river water still can answer the demand of irrigation amount of water required in Banjaran irrigation area. Exploiting of Network Irrigation for the supply irrigation water was less optimal. Efficiency management of irrigation water was very low. Usage of irrigation water in upstream area tends to excess of water and in middle area and go downstream area water insuffiency.
