Determinant study for improvement priorities of irrigation assets (a case study of Kedungrejo irrigation network in Pilangkenceng sub-district, Madiun regency – Indonesia)

Abstract

Irrigation plays an important role for increasing agricultural production in order to achieve national food sovereignty. However, in reality, requests of funding for the purpose of irrigation network management from year to year are not always fulfilled according to needs. As such, to resolve this issue, it is necessary to determine improvement priorities for repairs of irrigation assets so that management may be optimally carried out. The aim of this research is to determine and analyse the improvement priorities of irrigation assets in one of the irrigation areas of Madiun Regency. This study utilized the modified Irrigation Network Performance Evaluation Criteria and Weightings for the year 2018. In addition, statistical tests as the Kruskal-Wallis and Mann-Whitney tests were utilized, as the obtained data were in the form of rankings. Google Earth and ArcGIS software were utilized to facilitate the understanding of the conditions and management of all the assets. The required data was the inventory of the irrigation network. The results of the study showed that the Kedungrejo Irrigation Network has 10% of irrigation assets in very good condition, 37% in good condition, 49%, in fair condition, and 4% in poor condition. The highest ranking (ranking 1) was for the spillway, while the lowest ranking (ranking 82) was for a bridge.
