Abstract Swampy Irrigation Area (DIR) Technical Implementation Unit (UPT) Dadahup is a swampy irrigation area that needs serious handling of flood control. This flood is resulting in crop failure in several blocks. Furthermore, the malfunctioning of the main gates in controlling the entry and exit of water resulted in a long-standing inundation for the land. This paper presents the hydraulic system of the irrigation network of DIR UPT Dadahup by reviewing secondary data and documentation of field observations. Based on these parameters, the authors simulate the main primary channel using HEC-RAS to perform hydraulic analysis. The flow simulation results show that water entering the land inundated the three canal segments. One has the highest embankment elevation of 1,778 m, with the highest tide on the channel section of 2.25 m. Other results showed that water entering the land also inundated one channel section. The highest embankment elevation was 1,233 m, with the highest tide on the channel section being 1.4 m. From these results, the overflow of water was then eliminated by the heightening of the embankment.

The development process and flood control effects of the open-levee system, which was constructed from the mid-18th to the mid-19th centuries, on the Kurobe Alluvial Fan—a large alluvial fan located on the Japan Sea Coast of Japan’s main island—was evaluated using numerical flow simulation. The topography for the numerical simulation was determined from an old pictorial map in the 18th century and various maps after the 19th century, and the return period of the flood hydrograph was determined to be 10 years judging from the level of civil engineering of those days. The numerical results suggested the followings: The levees at the first stage were made to block the dominant divergent streams to gather the river flows together efficiently; by the completed open-levee system, excess river flow over the main channel capacity was discharged through upstream levee openings to old stream courses which were used as temporary floodways, and after the flood peak, a part of the flooded water returned to the main channel through the downstream levee openings. It is considered that the ideas of civil engineers of those days to control the floods exceeding river channel capacity, embodied in their levee arrangement, will give us hints on how to control the extraordinary floods that we should face in the near future when the scale of storms will increase due to the global climate change.

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.

Principles Of Justice

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.
