Jayanti, Nurul Dwi and Ir. Heri Suprijanto, MS. and Ir. Dian Sisinggih, ST., MT., Ph.D. (2023) Kajian Hidrolika Pelimpah Samping Dilengkapi Pintu Geser Bendungan Cabean Kabupaten Blora Provinsi Jawa Tengah Model Tes Skala 1:25. Sarjana thesis, Universitas Brawijaya.
Abstract
Pembangunan bendungan Cabean ditujukan utama sebagai upaya konservasi air di lokasi tersebut khususnya pada sektor pertanian yang membutuhkan suplai air yang cukup, maka direncanakan bendungan Cabean yang berlokasi di Sungai Galuk DAS Juana Desa Karanganyar Kecamatan Todanan Kabupaten Blora Jawa Tengah. Untuk penyempurnaan desain rencana, maka diperlukan model test (uji fisik) pada bangunan pelimpah samping dengan 2 pintu geser) untuk menyelidiki atau mengetahui perilaku hidraulika dan untuk menguji keamanan bangunan Pelimpah Bendungan Cabean. Pengukuran ini dilakukan 3 kali pengulangan yaitu seri 0 (original design), seri 1 (modifikasi design) dan seri 2 (final design). Analisis hidrolika dilakukan untuk melihat bagaimana kondisi aliran pada model pelimpah dan melihat kondisi gerusan lokal pada hilir sungai yang nantinya akan dibandingkan antara hasil pengukuran model, perhitungan analitis dan numerik menggunakan iRIC Nays2Dh 3.0. Hasil pengujian final design menunjukkan bahwa bangunan telah aman dari bahaya kavitasi, aliran getar dan kondisi gerusan sungai telah ditangani dengan penambahan perkuatan bronjong pada tebing sungai.
English Abstract
The construction of the Cabean dam is intended primarily as an effort to conserve water at the location, especially in the agricultural sector that requires sufficient water supply, so the Cabean dam is planned to be located on the Galuk River, Juana Watershed, Karanganyar Village, Todanan District, Blora Regency, Central Java. For the improvement of the plan design, a model test (physical test) is needed on the side spillway building with 2 sliding doors) to investigate or determine the hydraulic behavior and to test the safety of the Cabean Dam Spillway building. This measurement was carried out 3 times, namely series 0 (original design), series 1 (modification design) and series 2 (final design). Hydraulics analysis is carried out to see how the flow conditions in the spillway model and see local scour conditions in the downstream of the river which will later be compared between the results of model measurements, analytical and numerical calculations using iRIC Nays2Dh 3.0. The results of the final design test show that the building has been safe from the dangers of cavity, vibrating flow and river scouring conditions have been handled by the addition of gabion reinforcement on the river bank.
