It is possible for farmers, through Federation of Water Users’ Association (WUAF), as direct users to participate in the management of the irrigation system main network. The government of Yogyakarta Special Region (DIY) encourages WUAF to participate in the main network management so farmers understand the system comprehensively so that irrigation will be better managed and sustainably. This paper aimed to assess WUAF participation in irrigation system management as well as to identify factors influenced the participation level and to formulate strategies to improve WUAF participation. Based on their performances, WUAFs were clustered into three clusters, namely cluster 1 for WUAFs with good performance in all aspects, cluster 2 for WUAFs with financial weakness, and cluster 3 for WUAFs financial and institutional weaknesses. Strategy proposed for cluster 1 was minor government intervention to maintain WUAFs performance. Strategy proposed for cluster 2 and cluster 3 was pursuing independent funding source. Additional strategy for cluster 3 was institution strengthening through routine meetings and field workers. General strategies applicable for all clusters were improvement of WUAF role in the management of main network supported with appropriate training and selection of high-value agricultural commodities.

Organic vegetables grown special in planthouses require special irrigation practice to maintain the optimum range of soil water content throughout the cultivation season. The problem of irrigation is the absence of parameter that used to determine schedule and water irrigation. This research was to figure out whether the sprinkle irrigation used for Kailan vegetable in a planthouse could fulfil the water demand and the total water consumption based on change of water content. Herewith, the daily soil moisture was observed and analyzed the water flow in the soil based on the soil physical and hydraulic properties. The result showed that the soil water content was always within field capacity and permanent wilting point but 87% of cultivation period was lower than readily avaiable water (RAW). This condition indicated that the water irrigation is not optimal. Based on change of soil water content analysis, water consumption for kailan was 55 mm during cultivation with the consumption rate was 1.1 mm/day. The water requirement to attain RAW condition was 130 mm.

The development of an irrigated area is strongly influenced by water availability, water demand and availability of infrastructure. Water balance is the key to whether the water system in the irrigation area development plan can be realized according to currently existing condition because of an availability of water surplus, without needing improvement of existing dam efficiency and effectiveness. If there is a deficit of water, it still may require an amount of water through the construction of a reservoir upstream. In support of the development plan, a simulation between the extent of proposed irrigated area and water available is required, so that weir capacity for any alternative to the irrigation area development can be identified to meet the needs of development. Some simple methods and calculations can be used to simulate the required capacity of a weir upstream.

Limited water availability needs to be handled by water-efficient irrigation methods. JIAT which is built in Ponorogo has not been optimally utilized yet. So, it needs to be revitalized using both drip irrigation and solar energy system to operate the submersible pump. This study uses 51 solar panels covering area of 120 m2. Evaluation resuts of the technology application shows that solar energy can generate 7,873.5 watts, maximum discharge 14.17 liter/second, average CO2 emission reduction 4.1 kg/day, 96.51% irrigation uniformity, drip uniformity of 97.72% and emitter rate of 3.99 mm/hr. CO2 emission can be reduced until 1.29 tons for one pump operation on 10 consecutive months. Moreover, potential reduction of CO2 will reach 4.506 tons in a year if 50% of JIAT pumps from 7,000 existing pumps can be converted to be solar-based pumps. Water productivity for the cultivation of watermelon plants can be achieved as 35.63 kg/m3 water. The water-use efficiency is 60% - 92% compared to the similar research. In addition, pump-operation costs can be decreased to 94.92% compared to the cost of diesel-fueled pump.Â

Government Regulation No. 82 year 2001 regarding Water Quality and Water Pollution Control containing water quality criteria based on water quality classes, so water quality objectives with the wide range utilization become less specific then the quality of the irrigation raw water must meet class II, class III and class IV. On the other hand, the need of water for agricultural irrigation sector is a very large ammount and their needs is getting increase in line with population growth, while the availability of water is on the wane and more aggravated due to the presence of an increasingly severe pollution. Therefore, to meet the needs of large amounts of water with good quality increasingly difficult. It is very burdensome of raw water providers, “what the water quality criteria is needed for irrigation ? “ Based on the analysis of benchmarking several references and then to compose a propose of irrigation water quality criteria. Furthermore, evaluating water quality data of raw water irrigation in Walahar weir of Citarum River-Karawang, Pamarayan weir of Ciujung River-Serang and irrigation canal in Garang River Semarang. Based on the propose of water irrigation criteria resulted in good and very good classification, however, based on class II of water quality criteria resulted not suitable classification, however, it has good productivity that higher then the national average productivity. Indeed, the water quality criteria of Government Regulation No. 82 year 2001 is still prevailed for water quality standards determination and water quality objective standards is set up by other relevant regulations such as: Regulation of Government/Governor/Mayor based on their obligation.
