The main problem of the application of pressurized pipe irrigation on flat land is not enough energy, so it may cause problem during the operation of the network. Basically, the flow in the pipe can be designed as open flow, so energy requirement can be reduced. However, the application of pipe irrigation system has not been widely studied so it can not be applied to the field scale. This study aims to create a network of pipe irrigation design by gravity with open flow. The research was done by designing pipe irrigation on flat land in Pasir Salam 3 kiri tertiary area. Afterwards the analysis and evaluation of the design requirements was performed in order to get technical feasibility of implementation. As the results, the diameter of the primary pipelines ranging from 8 inches (200 mm) to 10 inches (250 mm) at a flow rate of 0.35 m/s to 0.50 m/s. While the diameter of the secondary and tertiary pipelines between 1 inch (25 mm) to 6 inches (150 mm) with a flow velocity of 0.25 m/s to 0.46 m/s. These results indicate that the design of the application of irrigation pipe networks on flat land in Pasir Salam 3 kiri tertiary area in the Panulisan Irrigation Area was technically feasible considering the results of hydraulic calculation. Thus the water can flow by gravity at velocity ranging from 0.25 to 0.5 m/s and energy availability 0.09 m larger than requirement.

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.

Regional development is targeted to make better growth in the rural area, by improving farmer’s welfare and minimizing the gap among the regions. In particular, the developement aims to increase farmers income percapita as an income indicators of development in rural area. In the irrigation area, the regional development can also increase the domestic revenue by providing value added program in this region. The existing regional plan (RTRW) of Cianjur in 2013 –2031 a part of the study area (Cihea irrigation system) are planned to be converted in to industrial area, it reaches 4209.903 ha. This research aims to provide an irrigation system based development strategy for guiding to the implementation of the RTRW. In the irrigation system, there are water resources and agricultural activities, mostly in food comodities. These resources will be considered in the study in order to achieve the target of rural development as for the implemention of RTRW. In this research, it analyzed supply and demand of irrigation, based on water balance calculation and farm production, the prospective industrial area in the region for processing the raw product of farming. As the result, the agricultural land convertion should be targeted into processing plant for rice. By these scenarios, the water resources were able to irrigate area of 5.484 ha with cropping pattern of rice-rice -secondary foodcrop as the minimum discharge occured in September its about 0.553 m3/second. The total production of this raw agricultural product can be processed to rice snack and cereal beside of rice, thus being able to gave rise in income of farmer to Rp 2.461.706,00 per planting season. Based on spatial analyze, the area which is can be developed are Ciranjang, Sukaratu, Sindangjaya, Mekargalih, Bojongpicung, Kertajaya, dan Cibiuk.

Penilaian Kinerja Irigasi berdasarkan Pendekatan Permen PU no.32/2007 dan Metode Masscote dengan Evaluasi Rapid Appraisal Procedure (RAP) di Daerah Irigasi Barugbug - Jawa Barat - Mulyadi; Indratmo Soekarno; Suardi Natasaputra

Irrigation performance is an indicator to description irrigation system management, Assesment Performance based on Permen PU 32/2007 made to the 6 (six) parameters including; Physical Infrastructure, Plant Productivity, Supporting Facilities, Personnel Organization, Documentation and Water User Association (P3A), whereas the assessment is carried out by evaluation method of MASSCOTE with Rapid Appraisal Procedure (RAP) which is a set of systematic procedures to diagnose obstacles, performance and level services in the system irrigation to 4 (four) main indicators include; Service Indicator, P3A Indicator, Human Resource of Operator Indicator, and Channel Operations Modernization indicator, performance assessment are taken by surveyor of respondents Operator irrigation, and farmers P3A, Show performance index by Permen PU 32/2007 gave the value 74.24% which has Well Performance Operations and Maintenance of Barugbug Irrigation, while the MASSCOTE methode show Performance 2.7 in level of Service which has Less Well Performance of Service and Operations Irrigation Channels. Based on the path analysis found significant influence with 4 (four) main indicator variables X1, X2, X3 and X4 to irrigation system performance variable (Y) of 0,701 or 70.1% with a residual error of 0.299 or 29.9%.

Increasing of land use changing causes more limited agricultural land. Micro irrigation is one of the solutions to increase agricultural productivity on a limited land. This study aims to design a micro irrigation system using mini-sprinkler in limited area of outdoor laboratory in Experimental Station of Irrigation, Bekasi. The plant will be cultivated is tomato. The results of design calculations obtained micro sprinkler type that will be used is HADAR 7110 Inverted Rotor as much as 12 units, wetting diameter of 10,2 m, the distance between the lateral and sprinkler 5 m x 5 m. Irrigation water requirement is 26,25 mm/ application. Time of the maximum irrigation is 5,13 hours, with the maximum irrigation interval is 5 days. Total dynamic head (TDH) required is 28,66 m. Considering to fulfillment greater requirement, the selected pump will be has a 0,25 KW BHP, discharge 1,25 liter/second, with total head of 60 m.. Schedule of irrigation water supply is designed based on the needs of water per growth period between 2,22 to 5,07 hours with an interval of 3-5 days.

Irrigation water provides on agricultural land should be used optimally, that automatic irrigation system that is able to provide crop water with the expected conditions are needed. For wide area the automatic irrigation system a use wireless sensor network system (WSN). The advantages of this system such as easy data download and the device is easy to install so the user will convenient to monitoring the entire irrigated area. In this research, XBee / XBee pro was used as wireless system devices with radio communication system and GSM modem device for SMS communication system. The objective of this research is to improve the efficiency of irrigation systems for wireless control. The benefits of this study is to provide an alternative automatic irrigation system for the region with limited water availability because the system is able to regulate irrigation water allocation according to crop needs (efficiency of irrigation water use).
