Earthquake incident in Sigi District, Central Sulawesi has damaging the Gumbasa Irrigation Scheme. Rehabilitation of irrigation network will be carried out gradually starting at firtst stage from the intake until the canal section of BGKn 8 (Sibalaya) which affected by the liquefaction. Irrigation operations need to be carried out gradually for the section which has been rehabilitated and ready to be operated so that the local community can immediately grow crops and not lose their livelihood. Nevertheless, the service area and required canal discharge will be much lower than the design so it will cause some water distribution problems. This research was conducted to formulate a pattern of irrigation operations in Gumbasa Irrigation Scheme in emergency situations where the canal discharge is much lower than the designed. Research was conducted by means of data collection and formulation of irrigation operation scenarios through hydraulic analysis. Simulated scenario was an operation without optimization, optimization by using existing sluice gate, and optimization using the skot beam. The results showed that irrigation operation without optimization can not be done because the elevation of water can not rise and flows to the secondary canal due to the large primary canal dimension. The use of a sluice gate optimization can only elevate water elevation by ±1 m from the base of the canal. In addition, closing the sluice gate can result in overflow in some canal segment. In the last scenario, utilization of the skot beam for optimization is the best solution. Skot beams can elevate water at the required height. Skot Beam is a infrastructure which quite good for a temporary irrigation operation where the water level can be adjusted even though the discharge is relatively small.

In carrying out irrigation system management in the irrigation area managed by the East Java Province in Mojokerto, PU Department of Water Resources of East Java experienced some constraint, namely irrigation infrastructure had expired, less of irrigation services and there was a decrease in storage capasity. Another constraint is population growth which has led to an increase in water use needs, food needs, conversion from agricultural land to settlements and industries and critical watersheds. In an effort to overcome these constraint, in addition to the operation, maintenance and rehabilitation, a comprehensive reform is needed, both institutional, technical, managerial, and human resources, known as irrigation modernization. Before carrying out irrigation modernization activities, it is necessary to have an assessment to measure the readiness levels of an irrigation area in carrying out modernization activities. First, determine the criteria that affect the modernization of irrigation, in this case there are 5 criteria and 34 sub criteria. Criteria weights were calculated using Fuzzy Analytical Hierarchy Process method. Then, priority scale of readiness irrigation area in carrying out irrigation modernization activities was determined using Simple Additive Weighting method. From 7 irrigation area managed by the East Java Province in Mojokerto, the resulting priority scale showed that modernization of irrigation can be applied to Kromong Irrigation Area. Modernization of irrigation should be postponed and carried out after revitalization on the Irrigation Area of Mernung, Sinoman, Penewon, Candi Limo, Jatikulon and Subontoro.

More efficient irrigation management is needed in the face of limited water availability and the increasing water requirements for other than agricultural sectors. This can be done by improving the accuracy of irrigation water through the optimizing of irrigation operation intervals. One effort which can be done is minimizing the time needed to report irrigation operation activities. using web-based application Irrigation Operations Management System (SMOPI). Research is conducted to identify the minimum time required for the reporting of irrigation operations, either manually or using SMOPI. The research was conducted as a case study in the Bondoyudo irrigation area by means of the collection of data through discussions and questionnaires as well as analysis of the time needed to report irrigation operation activities using the Critical Path Method. The result showed that the manual irrigation operations take 43 hours at the crop planning stage, 41 hours at the water delivery management, and 45 hours at the result recapitulation stage. The requirement of about 5 days at the implementation stage indicates that the operating interval of existing irrigation every 10 days is quite feasible. SMOPI is able to accelerate so that the operation time at the crop planning, water delivery management, and result recapitulation stage are 24.5 hours, 14 hours, and 31,5 hours. This indicates that SMOPI can be used to help shorten the interval of irrigation operations to support irrigation modernization.

One of the important programs to support the national food security is the development and rehabilitation of the irrigation network infrastructure. Spatial data on the location of existing irrigation networks becomes very important information for the policy of regional expansion of irrigation and monitoring of the damage of irrigation network infrastructure. High spatial resolution satellite imagery such as SPOT 7 and the Pleiades is capable of visually exposing the earth's surface objects, such as roads, rivers, and irrigation canals. Research was conducted to develop an irrigation canal identification procedure using high-resolution imagery. The identification procedure is done by combining the RGB composite image with false color, the canal index, and visual interpretation by recognizing the characteristics of the irrigation canal. Development of RGB composites and canal index was conducted based on the spectral pattern differences from the irrigation canal with spectral patterns of some similar objects. RGB composite imagery combined with canal index can clarify and isolate irrigation canals from surrounding object with some constraints in the canal width and crop shadows. Imagery interpretation techniques can ensure precise identification and distinguish irrigation canals with crop shadows. An image of SPOT 6/7 can be utilized for canal identification of more than 4 m in width, and the image of Pleaides for canal of less than 4 m in width. The total accuracy of the irrigation canal identification results using Pleaides imagery was around 82%.

The System of Rice Intensification (SRI) has been known in Indonesia since 1999. However, there are some difficulties in utilizing SRI water management recommendations in the field, particularly in combination with organic nutrient management. While many demonstrations have given impressive gains in productivity, many farmers remain skeptical about applying this system. The current study was carried out to analyze water balance components in SRI paddy fields when applying intermittent irrigation. The experiment was conducted in Gabus Wetan village, Indramayu District, West Java, Indonesia from 17 Nov 2016 to 1 March 2017. We involved a local farmer who had been trained in SRI methods at an Organic SRI Center on how to conduct organic SRI management in his fields. Weather and soil sensors were set up in the fields to acquire data on daily field conditions as well as on plant growth. Data on weathers such as precipitation, air temperature, relative humidity, and wind speed were collected automatically during the season every 60 min, as well as the soil water depth. Analyzing the data collected, water balance analysis was well performed with low error (1.00%) in which the water inflows through precipitation and irrigation were 560 mm and 865 mm, respectively, while the outflows by crop evapotranspiration, percolation, and runoff were 430, 306 and 675 mm, respectively. Compared to conventional rice farming as commonly practices by applying continous flooding irrigation, water productivities of organic SRI were 30% and 27% higher with respect to total water input (WPIR) and with respect to the amount of evapotranspiration (WPET, respectively. Organic SRI produced 33% higher yield than that the average of conventional methods in the same subdistrict. The key was intermittent irrigation by maintaining shallow water depth (nearly soil surface) in the vegetative and generative stages. Therefore, it is an attractive option to farmers in irrigated areas where water resources is limited due to regional climate change effects. Keywords:

Managing water in the paddy fields, water balance analysis is usually performed to determine the effectiveness of water used. However, with limited advanced instrumentation, time and cost, some water balance components are not measured. This study proposed a novel method, Linear Programming (LP) model, to estimate non-measurable water balance components. The aims of this study were to develop LP model in estimating non-measurable water balance components such as irrigation, runoff and percolation with measured soil moisture data in non-flooded irrigation, and then to evaluate performance of the model by comparing measured and estimated soil moisture. This study was carried out based on two season field experiments of non-flooded irrigation with System of Rice Intensification (SRI) in NOSC, Sukabumi West Java during 20 August to 15 December 2011 (first season) and 22 March to 5 July 2012 (second season). The developed LP model has the objective function by minimizing the differences between total measured and estimated soil moisture. In addition, the LP model has also constraint function and initial condition that were formulated based on actual field conditions. The results showed the LP model estimated non-measurable water balance accurately with the indicators of R2 > 0.85 (p value < 0.01) and percentage error less than 8%. Based on the estimation model results, irrigation only contributed 34-38% of inflow, while crop evapotranspiration and percolation contributed of 40-44% and 11-15%, respectively. Precipitation and runoff were the most contributors of inflow and outflow from the fields. By the current model, water use efficiency and water productivity can be determined with estimated irrigation.

The management of conventional irrigation system, which is still being applied in the recent time is probabilistic, especially in analyzing discharge for planning of irrigation operation and maintenance. It can be seen from the process of exerted data analysis, which is two-week or ten-days empirical data analysis. Therefore, to change the management of conventional irrigation system into modern requires flexibly and real-time based due to climate change in Indonesia. The available discharge prediction analysis is done using mathematic model analysis as the replacement of probabilistic model and the use of real time observation data by utilizing automatic weather observation technology. This new concept has been attempted in Irrigation Area of Wadaslintang and Banyumas Regency, showing that automatic weather observation worked successfully and can be used as the data within mathematic model analysis. The result indicates that telemetry instruments work well as expected. The difference between the use of mathematic method of Artificial Neural Network (ANN) with probabilistic method of P80 shows that ANN method is closer to real compared to the probabilistic P80. It is shown with the validation result measured from January to August 2015. Overall, errors between water surcharge prediction with ANN and realisation is 77%. According to the results, it is suggested that dynamic mathematic measurement method is needed, due to dynamic condition of climate in spite of not neglecting probabilistic method as comparison.

Irrigation system is very complex aspects, including irrigation water, irrigation area, the physical infrastructure of irrigation, human resources, irrigation institutional, management, financing, and technology which are interrelated to support agriculture. To increase agricultural production, the efforts made need to be formulated by considering the performance of the irrigation system and the influence of each related factor. This study aims to analyze the factors that influence of performance of the irrigation systems the irrigation area of district/municipality, province, central government in the semi-arid regions of Timor Island through the Principal Component Analysis (PCA) approach. Principal component analysis method uses fifteen indicators from 345 irrigation areas. This study concludes that fifteen variables showed a significant relationship both positive and negative towards the performance of the irrigation systems. The order of the biggest contribution of influences affecting the performance of the irrigation system in the main model component is the institutional aspects of the authority of the district/municipality irrigation area, productivity of rice, availability of supporting facilities for operation and maintenance, damage rate of drainage system, damage rate of secondary canals and damage rate of primary canals. The total cropping intensity shows a negative relationship to the performance of irrigation systems in semi-arid areas which water is limited. Meanwhile, the area of irrigation scheme, rice productivity, level of the participation of water user association, availability of supporting facilities for operation and maintenance, ratio of the number of operation and maintenance officers to irrigation area, frequency of maintenance of infrastructures, operation and maintenance costs, rehabilitation costs, authority of provincial irrigation areas show a positive relationship to system performance irrigation.

The Irrigation Area of Sumber Pakem has an irrigation service area of 1,151 ha, located in Jember Regency and Bondowoso Regency in the Province of East Java. The existing water supply system in the study area has not been implemented effectively and efficiently. Thus, there are problems in the water distribution during the dry season and fluctuations of water availability between the rainy season and the dry season in Banyubang River. The excess discharge in the rainy season can be stored and used to increase the supply of irrigation in the dry season. Therefore, the purpose of this study is to propose alternative irrigation operational method through the optimization of the surplus discharge of Banyubang River, the application of connected wells, and intensive rotation system. In this study, the proposed method was planned and its impact were evaluated on increased cropping intensity.The result showed that the utilizing of river surplus discharge in the study area can increase rice planting intensity during the Planting Season 1 by 2.03% and Planting Season 2 by 27.28%. The surplus discharge is also utilized to fill the 6,599 connected wells (103 network) with the addition of a discharge intake of 6.00 l/s for 135.33 days. The connected wells is filled during abundant river discharge when the irrigation was carried out continuously so as not to interfere with irrigation water distribution in the study area. Water which is stored in the wells can be used in Planting Season 3 to meet the water needs of tobacco plants covering an area of 467 ha. Thus, rice planting area in this period can be increased to 684 ha. The application of a connected wells and intensive rotation system in the Planting Season 3 can increase rice cropping intensity by 38.02%.

Increased awareness of precision agriculture in water management, requires various ideas and methods for its application in the fields. One idea that can be categorized into precision farming as well as appropriate technology, is evaporative irrigation. Evaporative irrigation is an idea to control the provision of irrigation water based on the direct response of plant water needs, namely evapotranspiration. The objectives of this study were to: (1) examine the theoretical aspects of the evaporative irrigation to be applied to plots of rice fields in a plot of plots with irrigation units, (2) laying out design principles for evaporative irrigation valve closures. The results showed that, theoretically, a controller pipe was needed which would be an indicator for thick water in the plot of rice fields. The pipe controller regulates the opening of the irrigation lid to the plot based on the float-ballast principle. The design principle is carried out by simulating the reduction in the controller water level of the controller which illustrates the decrease in thick water plots. Water depth that is still tolerated for rice growth will be the limit for the provision of irrigation water to the plots. Amount of irrigation water provided is equal to the value of plant water needs in the ongoing rice growth phase. One example of the design of the controller pipe water level to start and stop irrigation is at 117.8 mm water level and 300 mm respectively. The total water needs of one crop-season is calculated to be 625 mm. With the application of evaporative irrigation, the initial conditions of sufficient water do not require the provision of irrigation water until the 31st day. Irrigation water application after that, until harvesting, requires only 477 mm. Giving this water follows the plant water requirements calculated on a day-to-day basis.
