Abstract

Bendungan Marangkayu ini terletak di Kecamatan Marangkayu, Kabupaten Kutai Kertanegara, Provinsi Kalimantan Timur. Pembangunan Bendungan Marangkayu diharapkan mampu mensuplai kebutuhan air irigasi dan kebutuhan domestik penduduk disekitar Desa Sebuntal, Kecamatan Marangkayu. Perencanaan Bangunan Pelimpah (Spillway) ini direncanakan tegak lurus dengan tubuh Bendungan terletak disamping Bendungan. Spillway direncanakan dengan Ogee tipe I lengkap dengan bangunan pelengkap yaitu saluran pengarah, saluran transisi, saluran peluncur, dan saluran peluncur terompet serta bangunan peredam energi dengan tipe kolam olakan USBR Type IV. Analisa biaya minimum dilakukan terhadap pekerjaan tanah urugan dan pekerjaan beton K-300 untuk mendapat lebar optimum Bangunan Pelimpah. Dari hasil perhitungan yang telah dilakukan diperoleh curah hujan rencana periode ulang 1000 tahun adalah sebesar 201,17 mm, debit rencana periode ulang 1000 tahun adalah sebesar 402,37 m3/dtk. Dari hasil perhitungan analisa biaya didapat lebar optimum spillway 34 meter dengan total biaya Rp. 105.631.581.367,98. Mercu spillway dengan lebar 34 meter telah memenuhi syarat uji seperti gaya-gaya/ yang bekerja dan kontrol stabilitas. ========== Marangkayu dam is located in Sub-District Marangkayu, Kertanegara Kutai Regency, East Kalimantan Province. The construction of Marangkayu Dam is expected to supply the needs of irrigation and domestic needs of residents of the village of Sebuntal, Sub-District Marangkayu. The Spillway construction is planned perpendicular the body of Dam in addition Dam. Spillway is designed using Ogee type, complete with complement building: direction channel, transition channel, launcher channel, trumpet channel, and stilling basin USBR Type IV. The Minimum cost analysis conducted on earthworks and concrete work K-300 to obtain the optimum width of the spillway. From the results of the calculations that had been done, obtained rainfall return period of 1000 years is 201.17 mm, the planned flood discharge return period of 1000 years is 402.37 m3/ dt. The cost analysis calculation results obtained optimum spillway width is 34 meters with a total cost of Rp. 105,631,581,367.98. The top point of spillway with a width of 34 meters to qualify the test such as the forces or working and stability control.
