This paper presents the results of the study of one of the alternative decision support systems in determining the priority of irrigation maintenance. One of the obstacles in maintaining irrigation assets is the limited budget, hence the need for priority maintenance of irrigation. Batu City as an agricultural area, has not applied objective assessment criteria in determining the priority scale of irrigation asset maintenance to support the success of agriculture. Especially the irrigation area of Kali Brantas Sub Watershed which is the downstream area of Batu City, there are still many damaged irrigation assets infrastructure.
