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.

The Pandrah Irrigation Area is a technical irrigation network whose water source comes from the Krueng Pandrah river. Pandrah Weir was built in 1987 located in Samagadeng Village, Pandrah District, Bireuen Regency. It has an area of 1,203 hectares of irrigated rice fields. In its development, the damage that occurs in the Pandrah irrigation area also cannot be ignored. It is necessary to review it by assessing the performance of the irrigation system. The purpose of this study was to determine the performance index of the Pandrah irrigation system using the MASSCOTE (Mapping System and Service for Canal Operation Technique) method approach. The assessment of the performance index of the Pandrah irrigation system using the MASSCOTE method approach is carried out by evaluating the Rapid Appraisal Procedure (RAP) on four main indicators, namely service indicators, indicators for Farmers Using Water (P3A), indicators for the operator's Human Resources (HR). In the evaluation of the RAP, it is the value of observations of the respondents of OP officers and P3A farmers who are presented in a questionnaire to cross-assess each respondent in irrigation management. The results of the research on the performance appraisal of the Pandrah irrigation system based on the MASSCOTE method with RAP evaluation showed that the performance index of the absolute value (Level of Service) was 3.05. Hence, the performance index of the Pandrah irrigation system in the existing conditions was in the Good classification. This index and classification value shows the value of irrigation operations in fulfilling services from irrigation management carried out by operators / OP officers and felt by irrigation service beneficiaries, namely P3A farmers.

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.

At the stage of water treatment for irrigation systems, the efficiency capture coarse and fine mechanical impurities, as well as oil products and organic compounds affects the reliability of the equipment of the irrigation network and the safety of energy exchange processes in irrigated agricultural landscapes. The violation of work irrigation system can cause disruptions in irrigation schedules of agricultural crops, crop shortages, degradation phenomena on the soil and ecological tension. For the combined irrigation system, a water treatment unit has been developed, representing a hydrocyclone apparatus with a pipe filter in the case. For the capacity of 250 m3/h the main geometrical dimensions of hydrocyclone have been calculated. To organize the capture petroleum products and organic compounds, it has been proposed a modernization of a hydrocyclone unit, consisting in dividing the cylindrical part of the apparatus into two section. The first is section is for input irrigation water, the second one is for additional drainage of clarified irrigation water after sorption purification by the filter, placed on the disk and installed coaxially with the drain pipe and the pipe filter.

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.

Sistem subak adalah merupakan salah satu bentuk sistem irigasi yang mampu mengakomodasikan dinamika sistem sosio-teknis masyarakat setempat. Air irigasi dikelola dengan prinsip-prinsip keadilan, keterbukaan, harmoni dan kebersamaan, melalui suatu organisasi yang fleksibel yang sesuai dengan kepentingan masyarakat. Sistem irigasi erat kaitannya tentang pendistribusian air irigasi pada subak yang berdasarkan luas lahan. Salah satu aspek yang akan dinilai dalam sistem irigasi adalah Rasio Prestasi Manajemen (RPM) irigasi Tujuan penelitian ini adalah untuk mengetahui klasifikasi RPM di suatu subak dengan pemberian skor pada masing-masing klasifikasi RPM. Perolehan data sekunder dilakukan dengan metode survey, pengamatan secara langsung dan pengukuran. Data yang telah dikumpulkan selanjutnya akan dianalisis menggunakan metode Rasio Prestasi Manajemen (RPM) Irigasi. RPM irigasi setiap subak dinilai dengan menggunakan empat rentang nilai yaitu Baik bila 0.75 < RPM <1.25, Cukup bila 0.60 < RPM < 0.75 atau 1.25 < RPM < 1.40, Kurang 0.40 < RPM< 0.60 atau 1.40 <RPM<1.60 dan Sangat kurang bila RPM < 0.40 atau RPM >1.60 Hasil metode analisis rasio prestasi manajemen irigasi pada distribusi air di subak diperoleh RPM daerah hulu yaitu Pama Palian, Aya I dan Aya II memiliki RPM yang Baik yaitu rata-rata 100%. Ketersediaan air yang begitu melimpah karena subak daerah hulu, subak yang pertama kali mengambil air di daerah irigasi. Dan yang paling penting adalah sistim pengaturan pemberian air yang sudah optimal. Untuk subak daerah tengah RPM sedikit berbeda dengan di daerah hulu. Rata-rata RPM daerah irigasi tengah yang mempunyai kreteria Cukup yaitu sebesar 15,5% sedangkan Baik 84,5%. Untuk daerah irigasi tengah yang memiliki kriteria RPM cukup dengan nilai 15,5% disebabkan oleh pendistribusian air tidak seoptimal seperti daerah irigasi hulu. Untuk Subak daerah irigasi hilir rata-rata RPM secara keseluruhan yaitu 100% baik, ini disebabkan karena pembagian pendistribusian air daerah irigasi hilir sudah optimal sesuai dengan luas lahan.   Subak system is one form of irrigation system that is able to accommodate the dynamics of the socio-technical system of the local community. Irrigation water is managed with the principles of justice, openness, harmony and togetherness, through a flexible organization that is in accordance with the interests of the community. Irrigation systems are closely related to the distribution of irrigation water in subaks based on land area. One aspect that will be assessed in an irrigation system is the Irrigation Management Achievement Ratio (RPM). The purpose of this study is to determine the RPM classification in a subak by scoring in each RPM classification. Secondary data acquisition is done by survey method, direct observation and measurement. The collected data will then be analyzed using the Irrigation Management Achievement Ratio (RPM) method. Irrigation RPM for each subak is assessed using four ranges of values, namely Good if 0.75 <RPM <1.25, Enough if 0.60 <RPM <0.75 or 1.25 <RPM <1.40, Less 0.40 <RPM <0.60 or 1.40 <RPM <1.60 and Very less if RPM <0.40 or RPM> 1.60 The results of the analysis method of irrigation management achievement ratio in the distribution of water in the subak obtained by the upstream area RPM namely Pama Palian, Aya I and Aya II have a good RPM that is an average of 100%. The availability of water is so abundant due to the upstream subak, the first subak to take water in an irrigation area. And the most important thing is the optimal water supply management system. For the subak area the RPM is slightly different from the upstream area. The average RPM of the central irrigation area that has sufficient criteria is 15.5% while 84.5% is good. For the central irrigation area which has sufficient RPM criteria with a value of 15.5% caused by the distribution of water is not as optimal as the upstream irrigation area. For Subak downstream irrigation areas the overall average RPM is 100% good, this is because the distribution of downstream irrigation water distribution is optimal according to the area of ??land.

Krueng Baro Irrigation Area is one of the irrigation areas which is focused on increasing food crop productivity in Pidie District. To support the existence of the irrigation, of course, it must be supported by a well-organized irrigation system, so an effective irrigation network management system is needed through the O M program. O M activities require a truly real value or cost figure which is the result of the search for irrigation networks known as the real operation and maintenance demand value. The physical condition of the Krueng Baro Irrigation Network if viewed from the results of the irrigation network inventory still has many obstacles that hamper the fulfillment of rice water needs, including physical damage to buildings and irrigation channels. The evaluation of irrigation network performance is the first step in the preparation of the real operation and maintenance demand value, the rate of performance of the Krueng Baro Irrigation Area network is 68.06% (BWSSI, 2017) which falls into the less category and needs attention. This study aims to identify Irrigation Network O M activities and the real operation and maintenance demand value Krueng Baro irrigation. The research method is in the form of observations / field observations and documentation to obtain the existing conditions of irrigation networks which subsequently identify O M plans and preparation of the real operation and maintenance demand value. After the preparation of the real operation and maintenance demand value was obtained the output of the value of the real cost requirement in carrying out routine operations was only 0.53% (IDR 529,180,000.00), Routine Maintenance 6.52% (IDR 6,510,464,300.00), while for Periodic Maintenance is very large, namely 92.95% (IDR. 92,764,196,192.00) compared to the overall total cost (IDR. 99,803,840,492.00). In order to achieve the full O M Plan and the real operation and maintenance demand value Krueng Baro Irrigation Network due to the limited budgetary budget so is divided into a 5-year priority program plan reference to Minister of Public Works and Housing Regulation No. 12 / PRT / M / 2015 with the first year priority carried out on the main building which greatly influences performance and function of the irrigation system such as turnover of intake doors, olak ponds and upstream weir sediment excavation and some buildings and channels that have been destroyed and not functioning on the carrier channel.

<p>Abstract<br />Perkumpulan Petani Pengguna Air (P3A) coordinate with the users of irrigation water for other purposes through irrigation area coordination forum. Institutional financing irrigation management by irrigation farmers secaa a whole is still very limited ability to provision of funds operation and maintenance of irrigation networks when compared with the needs of maintenance of irrigation networks managed. The results showed that this indicator is quite good, although not all of them are active in every activity P3A. Some farmers feel that once a member but do not know the activities that will be implemented so that the benefits are still lacking at the farm level.Considering the amount of irrigation service charges under the authority of the local government, in this case the local government bureaucracy, we need a model of partnership with farmers. The main elements are dominant in this model is the behavior of (i) the farming community, (ii) participation of irrigation management, (iii) the physical condition of the irrigation network, (iv) of irrigation water services, and (vi) the management of irrigation networks.<br /><em>Keywords: farmer, water, irrigation, food.</em></p><p>Abstrak<br />Perkumpulan Petani Pemakai Air (P3A) melakukan koordinasi dengan para pengguna air irigasi untuk keperluan lainnya melalui forum koordinasi daerah irigasi.

One of the main factors for supporting development in the agricultural sector is the irrigation infrastructure management. Infrastructure is essential because it is a basic prerequisite for development and growth and requires very large costs. Therefore, the infrastructure must be managed properly according to Asset Management principles. This study aims to implement asset management in the management of Irrigation Area in the Salaman Technical Implementation Unit (UPT). The irrigation assets in question are the physical infrastructure of irrigation networks. This study requires an inventory of data on irrigation network which is used as input in analyzing the performance appraisal of irrigation assets. The assessment of the Irrigation Area Performance index is carried out through the weighting of each component according to the technical instructions set by the government. While the evaluation is carried out by determining priorities and types of handling irrigation areas through ranking and classification of aset condition index value. The evaluation show that 3 (three) Irrigation Areas get a condition index value of ≤ 60 (poor). The three irrigation areas are MA Depok, DI Pakem I, and MA Mudal. MA Depok is an irrigation area that is the first priority for treatment in the form of rehabilitation.
