Abstract

Within this physical hydraulic model of spillway of the Pidekso Dam, the experiment consisted of 9-series of testing; 4-series were testing of narrowing the angle of transition channel by 24 degree while 5others were by 12 degree. For the testing of series No.0 (original design) to No.8, the flow capacity was adequate for various discharges over spillway and outlet structure. Overall, the best hydraulic performance of the model was achieved by series No.4 in term of flow condition (uniformly distributed). This was a model of transition channel with angle of transition of 12 degree and no baffle apron used.Basically, all of testing of the model series No.0 to No.8 brought the positive impact to the downstream-part (section No.36) by considering the dissolved oxygen (DO) level. It was ranging from 11.1 mg/l to 14.2 mg/ l. According to the results of DO level, then only the series No.0 to No.3 were chosen as alternatives design for the case of transition channel with the angle of 24 degree combined with various dimensions of baffle apron. There were regular changes of DO level but the values were still lying above the minimum requirement level and were not harmful for fishery.By respecting to the eco-hydraulic concept, the downstream waterway was designed to be the stone pitching combined with vegetation. It was suggested that the bare floodplain at downstream-part need to be greening by mean of vegetation.Keyword: dam, spillway, baffle apron, dissolved oxygen

Abstract

Research attempts to understand the potential and demand of water and the water balance, the review on water balance at Watershed Renggung to ensure the satisfaction of the demand of irrigation and domestic waters at Central Lombok District. In this research water potential is 243.34 millions m3 comprising to 22.59 millions m3 river water, 252.51 millions m3 HLD supplement, and 1,309 mm rainfall or equaled to 252.51 millions m3. River water supply is calculated based on 80 % (Q80) dependable discharge from AWLR Renggung- Ponggong in the period from 1992 to 2011. Discharge is used as the guidance to determine water availability at Watershed Renggung. Result of analysis indicates that the maximum discharge is available at 3.658 m3/ second on March. The average debit is 0.721 m3/second, while the minimum discharge is 0.608 m3/second on October. The current water demand for multi-sectors is 225.11 millions m3. These multi-sectors include domestic, irrigation, animal husbandry, fishery and industry. For the industry, the water is supplied only to the industry in the sub-district at the Watershed. The analysis devices for water availability involve the analysis of rainfall and the analysis of surface water.The water demand total at Watershed Renggung for the next 25 years is estimated in the average as 227.58 millions m3. This total figure consists of: 208.40 millions m3 for irrigation water, 7.59 millions m3 for domestic water, 5.40 millions m3 for animal husbandry, 4.90 millions m3 for fishery, and 1.30 millions m3 for industry. The prediction of water demand total from 2011 to 2031 based on Water Demand Index (IKA) Standard of NSAD at NTB Province is 94.75 % in average, meaning that the water use rate is critical. By 2036, IKA is assumed as 101.87 meaning that the water use rate will be deficit.Keywords: water demand, water availability, water balance

Abstract

Dalam rangka menuju kemandirian dan ketahanan pangan ,maka pemerintah berupaya untukmeningkatkan produksi beras dan taraf hidup petani sehingga diperoleh manfaat penghematan devisa nasionaldan membuka kesempatan kerja serta mengurangi kemiskinan. Tujuan dan manfaat studi adalah penyusunansrtategi dan kebijakan pemberdayaan Lembaga Pengelola Jaringan Irigasi di tingkat desa dan sebagai pedoman untuk meningkatkan keberadaan HIPPA sebagai lembaga pengelola jaringan irigasi yang mandiri dalam pengelolaan maupun pemeliharaan jaringan irigasi . Metode yang dipergunakan adalah analisis SWOT untukmenentukan Strategi kebijakan pemberdayaan HIPPA. Hasil studi menunjukkan bahwa keberhasilan pemberdayaan HIPPA diperlukan strategi dan kebijakan sebegai berikut : organisasi HIPPA harus berbentuk badan hukum, pemerintah sebagai fasilitator, motivator, mengadakan kerja sama pengelolaan, menyediakan tenaga pendamping, menyediakan sarana produksi dan memfasilitasi pembentukan koperasi serba usaha.Kata kunci : Pemberdayaan, irigasi, HIPPA

Abstract

Di Jaringan Irigasi Prambatan kiri terjadi kekurangan air pada penerapan pola tata tanam eksisting penyebab utama terjadinya kekurangan air tersebut karena adanya penyimpangan dalam pelaksanaan pola tata tanam yang telah ditetapkan , misalnya pada saat musim kemarau yang seharusnya diperuntukkan untuk tanaman polowijo oleh petani diganti menjadi tanaman padi. Tujuan dari penelitian ini adalah untuk mengetahui berapa luas tanam dan keuntungan yang diperoleh pada kondisi eksisting dan kondisi setelah dioptimasi, sedangkan manfaatnya adalah sebagai informasi bagi instansi terkait dan petani setempat tentang pola tata tanam yang sesuai dan hasilnya maksimal. Metode yang digunakan dalam penelitian ini adalah optimasi pola tata tanam dengan program linier dengan menggunakan pakket program solver. Hasil optimasi dari beberapa alternatif pola tata tanam yang dicoba dipilih alternatif ke II (Padi/Apel - Padi/Palawija/Apel - Padi/Palawija/Apel), karena diperoleh keuntungan yang paling maksimumKata kunci : pola tata tanam, pemberian air irigasi, optimasi program linier
