Abstrak : Analisis Laju Angkutan Sedimen di Sungai Luas Bengkulu Dengan Menggunakan Metode Shen Hungs Dan Engelund Hansen. Sungai Luas yang berada di Provinsi Bengkulu mengalami permasalahan sedimentasi pada alur sungai sehingga alur sungai menjadi rusak dan terjadi pendangkalan yang mengakibatkan sering terjadi banjir, dimana sungai tersebut tidak mampu menampung air hujan yang ada. Selain itu, delta delta di hilir sungai yang membentuk pulau-pulau kecil. Tujuan dari penelitian ini adalah untuk mengetahui besarnya laju angkutan sedimen yang terjadi di Sungai Air Luas. Metode yang digunakan untuk menghitung besarnya laju transpor sedimen adalah Metode Shen Hungs dan Engelund Hansen. Hasil pengukuran di lapangan rata-rata lebar sungai bisa 67,5 meter dan kedalaman 0,45 meter, debit 56,9 m3/detik. Hasil perhitungan dengan menggunakan metode Shen dan Hungs, diperoleh laju sedimen sebesar 1.742.040 ton/tahun dan. Sedangkan Metode Engelund dan Hansen menghasilkan laju angkutan sedimen sebesar 1.643.760 ton/tahun. Kesimpulan dari penelitian ini menunjukkan bahwa laju transpor sedimentasi di Sungai Air Luas terjadi secara terus menerus akibat rusaknya DAS bagian hulu yang menyebabkan terjadinya erosi dan sedimentasi di alur sungai. Sedimentasi yang ada menyebabkan alur sungai menjadi dangkal dan sering terjadi banjir. Untuk itu diperlukan pengelolaan DAS dan pengerukan sedimen secara terpadu secara berkala agar tidak mengganggu aliran air yang terjadi di air Sungai Luas, Bengkulu. Abstract : The Analysis Of Sediment Transport Rate In Luas River of Bengkulu by Using Shen Hungs And Engelund Hansen Methods. The River of Luasis located in Bengkulu Province, which experiences problems with sedimentation in the river channel so that the river channel becomes damaged and siltation occurs, which results in frequent flooding, where the river cannot accommodate existing rainwater. In addition, the delta delta in the lower reaches of the river that forms small islands. The purpose of this study is to determine the magnitude of sediment transport rates that occur in the Air Broad River. The method used to calculate the amount of sediment transport rate is the Shen Hungs and Engelund Hansen Method. The results of field measurements in the average width of the river can be 67.5 meters and a depth of 0.45 meters, a discharge of 56.9 m3 / sec. The results of calculations using the Shen and Hungs method, obtained sediment rate of 1.742,040 tons / year and. Whereas the Engelund and Hansen Method produces sediment transport rates of 1.643,760 tons / year. The conclusion of this study shows that the rate of sedimentation transport in the Air Luas River occurs continuously due to damage to the upstream watershed which causes erosion and sedimentation in the river channel. Existing sedimentation causes the river channel to become shallow and frequent flooding. for this reason, integrated management of watersheds and sediment dredging is needed regularly so as not to disrupt the flow of water that occurs in the River water of Luas, Bengkulu.

Irrigation efficiency is a major determinant in the system of scheme irrigation . Irrigation efficiency is assumed as part of water would be lost either in the channel or at the rice terraces. Water loss estimate in efficiency include loss of water efficiency tertiary and secondary level, water loss is influenced by the length of the channel, the surface area of the channel, the wet cross section and the position of groundwater. The analysis in this study is to calculate thevalue of the efficiency the secondary and the tertiary canals of irrigation of Kemumu, North Bengkulu. Efficiency is accounted based on the length of the channel, sectional area of wet channel, water velocity, water loss, evaporation and seepage channel. The water loss average of secondary channel is 26,12 mm3/sec. seepage average for secondary channel is 5,06 x 10 mm/day. Evaporation in one year is 0,05 mm/day. The results of this study stated that the efficiency of the secondary channel efficiently deliver water from the primary channel to channel tertiary the average of efficiency is about 11,92%. The result of this analysis is expected that not efficient channels in Kemumu North Bengkulu can be fixed, so thewater that rice field needed can be fulfilled. The channels can be fixed with some ways, such as making theconcrete irrigation and doing the rutine maintenance.
