T The availability of supporting facilities and infrastructure for the agricultural sector, such as a quality irrigation system, is very neccessarry. The need for the availability of irrigation networks in Ngada is the main factor for the government to excecute the development of irrigation networks in Ngada district. One of them is through the construction of an irrigation network in the Hobotopo irrigation area in 2020. The main obstacle to the implementation of this project The impact of Covid 19 on the implementation of the continued construction of irrigation channels in D.I Hobotopo and social constraints and extreme weather made the project implementation completely obstructed. This study aims to analyze how much the cost and time performance of the project development project and to find out the cost and time predictions until the completion of the project so that it can be used as an evaluation material regarding corrective actions for further performance. This study uses the Earned Value method to examine the data in order to obtain conclusions in the form of project time and cost performance. The result of this research is that this project is experiencing delays, where until the end of the review period, namely until the end of the week under review, which is the 14th week, the SPI value is 0.18. the progress planned until the 14th week of 30,15%, just realized by 6.89% where this means there is a delay in schedule by 23,26%. Apart from that, in terms of cost, this project has experienced an increase in costs. This is indicated by the CPI value of 0.64 (lower than 1) until week 14. With the cost and time performance calculated until the end of week 14, the time prediction value is obtained at 158 weeks. This result is very far from the target time of 36 weeks. Meanwhile, the cost prediction value until the end of the project is IDR 40.859.622.397. The final project cost prediction has swelled to almost double the value of the project budget, which is IDR 19,320,242,454.70.
