Priority Handling of Teurebeh Irrigation Assets, Aceh Besar District, Aceh Province

Abstract

Teurebeh Irrigation scheme is one of the promising irrigation areas in Aceh Besar District, Aceh Province. It is also one of the buffers in the agricultural sector, covering 750 hectares of agricultural area. However, the construction has shrunk over time, and the evaluation at the end of 2020 classified it as "Poor Performance and Requiring Attention." This study aims to determine the handling priority for the irrigation networks at the Teurebeh Irrigation scheme. Data on irrigation network inventory was used as input. The determination of handling priority was conducted using the Mann-Whitney method. The ranking for determining the importance of irrigation assets is based on the condition and function of the irrigation assets. ArcGIS and Google Earth software were used to determine the condition and handling of all assets. The results show that the handling priority levels are between the primary and secondary channels. The tapping structure of BDT.8, BDT.6, BDT.4, BDT.1, and BDT.7 are ranked 1 to 5, meaning they must be fixed immediately as the conditions are severe to moderately damaged and not functioning to functioning poorly. BDT.1 to BDT.3 is in the Primary Channel, while BDT.4 to BDT.8 is in the Secondary Channel. The handling priority for irrigation construction in the primary channel (BDT.1, BDT.1a, and BDT.1c) and the secondary channel (BDT.8, BDT.6, and BDT.7a) are within priority 1 to 3. The Mann-Whitney test on the proposed hypothesis comparing the urgency level between the two channels is insignificant, indicating no significant difference between the handling of primary and secondary channels, as both have similar conditions and functions. The results are expected to contribute to decision-making at the Irrigation Department in designing proposals for renovating irrigation networks.
