Abstract

Spillway adalah salah satu komponen bendungan yang berfungsi untuk meluapkan debit aliran air lebih atau banjir. Di Provinsi Bali sekarang sedang dibangun bendungan di perbatasan Desa Titab dan Desa Ularan, Kecamatan Busungbiu, Kabupaten Buleleng. Bendungan multi-fungsi tersebut memiliki spillway yang dapat dimanfaatkan sebagai PLTA 2 x 0,75 MW. Spillway yang akan direncanakan adalah spillway submersible. Adapun bendungan yang direncanakan memiliki periode ulang 1000 tahun dengan luas DAS Saba sebesar 69,54 km2 dan panjang sungai 15 km serta data hujan harian sebanyak 18 tahun. Proses perencanaan dengan menggunakan metode curah hujan rata-rata polygon Thiessen, distribusi frekuensi log pearson tipe III, hidrograf banjir GAMA I, dan perencanaan dimensi spillway dengan tinggi yang disesuaikan untuk menghasilkan daya listrik. Berdasarkan kajian diperoleh debit banjir maksimal 379,962 m3/dt. Rencana elevasi puncak bangunan adalah +131,2 Mdpl, elevasi inlet +102,88 Mdpl, dan elevasi outlet +96 Mdpl. Tinggi bangunan 35,2 meter dengan diameter puncak 4 meter dan diameter konduit 3 meter. Panjang terowongan konduit 231,52 meter. ========== Spillway is one of dam component that serves to vent discharges are more or flood. In Bali is being built dam now, at the border Titab Village and Ularan Village, Busungbiu subdistrict, Buleleng regency. Dam multifunction has a spillway that can be used as a 2 x 0.75 MW hydropower. Spillway to be planned is the spillway submersible. The planned dam has a return period of 1000 years with extensive DAS Saba of 69,54 km2 and a length of the river is 15 km and daily rainfall data as much 18 years. The planning process by using the average rainfall Thiessen polygon, frequency distribution of the log Pearson type III, flood hydrograph GAMA I, and planning dimensions with high spillway adapted to produce electrical power. Based on the study obtained the maximum flood discharge 379.962 m³/sec. Top elevation plan of the building is +131.2 mdpl, +102.88 mdpl inlet elevation and +96 mdpl outlet elevation . Building height 35.2 meters with a top diameter 4 meters and 3 meters of diameter conduit. Conduit tunnel long 231.52 meters.
