Abstract

Bandara Internasional Ahmad Yani merupakan bandara yang melayani penerbangan di Jawa Tengah dan kota Semarang khususnya. Meningkatnya kebutuhan akan transportasi yang memadai, mendorong perlunya akan perluasan bandara. Proyek pengembangan Bandara Ahmad Yani bertujuan untuk menambah kapasitas bandara, dari pengembangan bandara maka diperlukan sistem saluran drainase yang mampu mengakomodir debit limpasan air yang ada. Pengerjaan Tugas Akhir ini dilakukan dengan metode analisa hidrologi dan analisa hidrolika untuk menghitung debit banjir rencana yang akan terjadi di area bandara. Pertama menghitung Intensitas hujan dari periode ulang hujan 5 tahun. Selanjutnya menghitung luas total cathment area dihitung untuk mengetahui luas DAS saluran. Setelah itu ditetapkan nilai koefisien rembesan untuk masing-masing cathment area. Setelah itu akan didapatkan debit hidrologi yang akan diproyeksikan ke debit hidrolika. Kemudian baru direncanakan dimensi saluran sesuai perhitungan yang tersedia. Dan yang terakhir akan direncanakan alternatif solusi jika diperlukan untuk mengatasi pengaruh backwaternya. Perhitungan debit rencana saluran akhir diperoleh 8,48m3/dt sehingga saluran direncanakan lebar 7m dengan tinggi saluran 1,2m. Adanya pengaruh backwater dari data pasang yang ada menyebabkan direncanakan kolam dengan dimensi 150m x 80m yang dioperasikan dengan pintu ketika surut dan penggunaan pompa kapasitas 2m3/dt sebanyak 3 buah ketika adanya pasang air laut dilevel +0.95. ========================================================================================================== Ahmad Yani International Airport is the airport which serving flights in Semarang city of Central Java particular. The growing needed for availabling transportation will spur the expansion space of the airport. The purpose of Ahmad Yani Airport development project is to increase the capacity of the airport, from airport development will require a drainage channel system which able to accommodate the existing discharge water runoff. The execution of this final project is done by analysis of hydrology and hydraulics analysis method to calculate the flood discharge plan that will occur in the area of airport. Firstly, calculate the intensity of the rain of the annual rainfall on 5 years. Secondly, calculate the total of cathment area which calculate for determining the channel basin area. After that set the value of the coefficient of seepage for each cathment area. And than to obtain hidrologic discharge that would be projected to discharge hydraulics. After the planned new channel dimensions according to the calculation provided. And the last one planned alternative solutions if essential to cope with flooding. Calculation of the final discharge channel plan which obtained 8,48m3 / dt planned. So that the channel width 7m by 1.2m channel height. The influence of tide data backwater causing the planned pool with 150m x 75m dimensions which operated by the door when it was receded and the pump which having capacity of 2m3 / second 3 pieces when the tide level +0.95.
