Abstrak. Daerah Aliran Sungai (DAS) Krueng Aceh memiliki jaringan irigasi permukaan teknis untuk mengairi 7.450 ha lahan sawah di Kabupaten Aceh Besar. Peningkatan tekanan pada sumber daya air yang tersedia untuk irigasi dan kebutuhan lainnya, terutama selama musim kemarau, membutuhkan jaringan irigasi yang memiliki efisiensi yang tinggi untuk menyalirkan air irigasi. Penelitian ini bertujuan untuk mengetahui efisiensi penyaluran dan jumlah kehilangan air di saluran sekunder dan tersier dari jaringan irigasi pilihan yaitu Jaringan Lam Raya.Hasil penelitian menunjukkan bahwa efisiensi penyaluran rata-rata untuk BKA Kn 16 Lam Raya adalah 52,47%. Rata-rata kehilangan air dan efesiensi penyaluran air di saluran sekunder berturut-turut adalah 0.048 m3/dtk dan 81,11%. Kehilangan tersebut disebabkan oleh penguapan 2,73 x 10-7 m3/dtk, rembesan 0,00212 m3/dtk dan faktor lainnya 0,04548 m3/dtk. Kehilangan air rata-rata di saluran tersier adalah 0.01 m3/dtk yang merupakan kehilangan akibat adanya penguapan 5,046 x 10-8 m3/dtk, rembesan 0,00033m3/dtk dan faktor lainnya 0,00994 m3/dtk. Hal tersebut menyebabkan efisiensi penyaluran air di saluran tersier sekitar 71,88%. Namun, kinerja jaringan irigasi masih dikategorikan baik karena memiliki efisiensi penyaluran air yang lebih besar dari 60%. Kehilangan air di saluran tersier sebagian besar disebabkan oleh banyak bagian dinding dan dasar saluran yang rusak, dan adanya vegetasi dan sedimen pada saluran yang memperlambat aliran air. Conveyance Efficiency Of Irrigation Water At BKA Kn 16 Lam Raya Krueng Aceh Irrigation Area Abstract. Krueng Aceh Watershed has technical surface irrigation network to irrigate 7.450 ha of paddy fields in Aceh Besar District. Increasing pressure on available water resources for irrigation and other needs, particularly during dry season, requires an irrigation network having a higher level of efficiency to deliver irrigation water. This study aims to determine the delivery efficiencies and amount of water loss in secondary and tertiary channels of selected irrigation network. Lam Raya network was selected for the study area. Results showed that average delivery efficiency for BKA Kn 16 Lam Raya was 52.47%. The average water loss and water delivery efficiency in secondary channel were 0,048 and 81,11%, respectively. The loss was caused by evaporation 2.73 x 10-7 m3/s, seepage 0.00212 m3/s and other factors 0.04548 m3/s. The average water loss in tertiary channels was 0,01 m3/s contributed by losses from evaporation 5.046 x 10-8 m3/s, seepage 0.00033 m3/s and other factors 0.00994 m3/s. It caused tertiary channel's water delivery efficiency was approximately 71,88%. However, performance of irrigation network was classified as good since it has water delivery efficiency greater than 60%.  Water loss in tertiary channel largely due to many parts of wall and base of the channels were broken, and the presence of vegetation and sediment in the channel slowed the water flow.

Cikarang Bekasi Laut (CBL) is a fixed-dam river-flow that flows through the building for upstream srengseng channel. Srengseng Hilir Secondary-Channel has 32 buildings for watering the rice fields in the Sukatani sub-district. The problem happened in the distribution of water when there is a loss of irrigation water due to infiltration of water into the soil where the soil is saturated. This causes a shortage of debit for field irrigation due to water loss in the secondary channel. The method used in Water Supply Evaluation of Irrigation Cikarang Bekasi Laut (CBL) for the Secondary Channel Srengseng Hilir D.I. Jatiluhur are the maximum discharge data, minimum discharge, and average discharge of the Fixed Cikarang Bekasi Laut (CBL) Dam in 5 year-period and calculating water requirements and water availability in D.I. Jatiluhur. Result showed that the P1 channel has an irrigation area of 105 ha and a channel length of 1906 m with an actual discharge of 2714 liters/sec and has irrigation efficiency of 5.71%.

The Kelingi Tugumulyo Irrigation Area is a permanent weir irrigation that runs through the building for the Satan Muara Beliti Water channel. Secondary Air Satan Muara Beliti channel has 5 buildings with the main function to flow the water through the rice fields in the Mara Beliti sub-district. Problems that arise in the distribution of water are the loss of irrigation water due to the pool of swift water and infiltration of water into the soil if the soil is saturated. These problems cause a lack of discharge for the fulfillment of irrigation water due to water loss in the secondary channel. The method used in assessing the Evaluation of Irrigation Water Provision from the Watervang Dam for Satan Water Secondary Channels was by analyzing the data of maximum discharge, minimum discharge, and average discharge of the Watervang Dam as well as calculating water demand and water availability in the Satan Muara Beliti Water Irrigation Area. There are three results about Tanah Priuk 1 weir channel (BTP1) condition. First, based on the plan discharge, according to the Kelugi Tugumulyo Irrigation network scheme, debit from BTP 1 to BTP 2 was 30.10 l/s, whereas the result from field calculation through the use of current meter was 7.89 l/sec; it means the lack of water from the plan for BTP 1 - BTP 2 which is 22.21 l/sec. Second, the debit from BTP 2 to BTP 3 was 10.80 l/sec, whereas the result from field calculation through the use of current meter was 6.20 l/s; it means the lack of water from the plan for BTP 2 - BTP 3 was 4.60 l/sec. Third, the debit from BTP 4 to BTP 5 was 11.10 l/sec, whereas the result from field calculation through the use of current meter was 6.92 l/s; it means the lack of water from the plan for BTP 4 - BTP 5 was 4.18 l/sec . It concluded that the secondary channel from BTP 5 to the village of Bali has insufficient water.

The Cubo Trienggadeng Irrigation scheme has a potential area of 1,545 Ha while the functional area is 1,090 Ha. Based on the Irrigation Network scheme, Cubo Trienggadeng Irrigation Area consists of 3 (three) zones: Zone I, Zone II and Zone III. In Zone III of the Cubo Trienggadeng Irrigation Area which is the latest area receiving water from the Cubo Trienggadeng Weir often occurs in water shortages especially during the Gadu planting season (second planting season). Embung Paya Sepat is the reservoar found in Zone III D.I. Cubo Trienggadeng that is not being fully optimized in use. This study aims to optimize the utilization of Paya Sepat Reservoar so that it can meet irrigation water demand in Zone III D.I Cubo Trienggadeng by using the Water Balance method. This reservoar does not have a channel that supplies inflow discharge, so rainwater harvesting becomes a parameter in analyzing the supply of water to the reservoar. The optimization technique used uses a non-linear program using the Solver facility in Microsoft Excel software. Based on the results of the calculation of irrigation water requirements for an area of 204.50 Ha in the Gadu planting season, the maximum volume of irrigation water demand is 40,461,55 m3 at first periode in June, from the results of the optimization using the Maximize Release method, the results show that the water reservoar in Paya Sepat Reservoar can meet the water requirements in the Gadu planting season with an average reliability of 100%.. Therefore it is necessary to regulate the release of irrigation water that is well regulated and coordinated between the reservoar management and water users/farmers.

Irrigation water shortages have the potential to limit agricultural development otherwise arable land. To resolve such irrigation water shortages, accurate evaluations focusing on the assessment of the irrigation system’s physical condition, the functionality of the infrastructure components, and the irrigation efficiency are all needed. The assessments of physical condition and functionality are metrics used to establish the performance index value of the irrigation system. The performance index value can be used to identify sections that need maintenance and to define the level of damage that has impacted the irrigation network infrastructure. The irrigation network’s overall performance is analyzed based on the weight of each criterion as defined in the Minister of Public Works Regulation No.32 Year 2007. This research location is Tlatak Irrigation Area, in the District of Parang, Magetan Regency. The results of the analysis showed that the efficiency of irrigation was 74.24%, and the irrigation system performance was only 61.11%. These numbers indicate that the Tlatak irrigation network is categorized as ‘Requiring Attention.' Efforts should be made to resolve the irrigation issues by conducting periodic maintenance, constructing one or more deep wells, and enhancing the role of the Water User Farmers’ Association.

Assessing available water resources and their potential for irrigation water use is vital for sustainable agricultural development and planning. This is particularly of interest in developing countries like Ethiopia, where a small portion of largely accessible land for surface irrigation applications has been utilized, despite the majority of the population relying on agricultural productivity. This study utilized the Dhidhessa River Basin (Ethiopia) as a case study and analyzed the main challenges to balance the sustainable water resources utilization and enhance agricultural productivity of the basin. The study mainly focused on estimating the available water resources and their potential for surface irrigation water use in the basin. This was achieved by utilizing Geographic Information System (GIS)-based tools, a hydrological Soil and Water Assessment Tool (SWAT) model, and a Crop Water and Irrigation Requirements Program of FAO (CROPWAT) model. While the SWAT estimated the water availability in the basin, GIS-tools such as Model Builder were used to map the irrigation potential of the basin. For irrigation water potential assessment, we selected six crops (cabbage, maize, tomato, pepper, groundnut and sugarcane) and estimated their irrigation water requirements using the CROPWAT model. We developed the SWAT model for the period from 1986 to 2012 using the available hydro-meteorological and geo-spatial data. Due to many parameters used in the model, we first performed a parameter sensitivity analysis and identified the most essential/sensitivity parameters via Sequential Uncertainty Fitting-II (SUFI-2). The identified sensitive parameters were subsequently used for model calibration (1989–2000) and validation (2001–2012) procedures achieved via SUFI-2. SWAT was able to reproduce the observed monthly streamflow values with a coefficient of determination (R2) and Nash-Sutcliffe Coefficient (NSE) of 0.85 and 0.87 for the calibration period and 0.91 and 0.89 for the validation period, respectively. The findings generally indicated a “good” performance of the model in simulating the hydrology. The annual available water of the basin is 9.26 billion cubic meters (BCM) whereas the 70% and 80% dependable flow is 7.56 and 6.97 BCM, respectively. Based on the Model Builder of ArcGIS, the SWAT estimated available water can potentially irrigate an area of 259,028 ha for slope less than 8%, 643,162 ha for slopes less than 15% and 1,023,581 ha for slopes less than 30%. Moreover, the irrigation water requirements were calculated by the CROPWAT model for the six selected crops indicated that although the need for irrigation water varies depending on the season, the potential irrigation area of the Dhidhessa River Basin is greater than its irrigated land. Therefore, it is concluded that the basin’s surface irrigation systems need to be expanded to enhance the agricultural productivity and improve the livelihood of the basin’s communities and similar basins elsewhere.
