Irrigation Maintenance Priority Analysis (Case Study: Irrigation Areas in Salatiga City)

Abstract

The absence of a standard reference and limited funds for determining the classification of irrigation maintenance and rehabilitation activities in the Salatiga become an important research nowadays. Budget funds for 14 irrigation areas come different sources. Those funds are limited only to support the maintenance activities, while the rehabilitation activities rely on funds from the provincial and central governments that are not easily to be approved. Therefore, it is necessary to analyse the classification and the priority of irrigation activities. In this research, the grouping analysis employs two assessment criterias, namely; physical condition of irrigation networks and irrigation performance indices. Assessment of irrigation performance indices according to PU Minister’s Regulation Number 32/PRT/M/2007 is for technical irrigation status, therefore it is necessary to identify adjustments to existing conditions. The priority analysis of irrigation maintenance activities in this research uses Analytical Network Process (ANP) method. The criterias that are investigated are irrigation performance indices, area width, irrigation status, estimated cost and distance of warehouse to intake. In this research, 4 groups of identifying the classification of irrigation status, i.e. i) technical irrigation, ii) semi-technical irrigation with weir main building, iii) semi-technical irrigation with spring pond main building and iv) simple irrigation, are used. The results of the grouping analysis showed that 11 irrigation areas are included in irrigation maintenance activities. The results of the priority analysis of irrigation maintenance activities from the first to the last priority are; Kedungkopyah, Cengek, Kedawung, Andong, Banyuputih, Siluwing, Sijamban, Bonorejo, Siandran, Sijambe, and Plampeyan. By determining the priority of irrigation maintenance, the budget allocation will be more targetted.
