Abstract

Pada tugas akhir ini memakai 3(tiga) desain bendungan antara lain desain eksisting, desain alternatif I, dan desain alternatif II. Pada semua desain tersebut ditentukan permodelan MAB +223,11, MAN +221,30 dan Surut Cepat dari kondisi MAN sampai Mercu Intake +198,00. Analisis desain menggunakan program bantu Geo-Studio 2012 dan akan menghasilkan analisis berupa pola rembesan, kecepatan rembesan, debit rembesan dan angka keamanan pada lereng hulu dan hilir yang mana angka tersebut mengacu pada SNI 2016.
Hasil analisis desain menunjukkan bahwa rembesan yang terjadi tidak terlalu banyak perbedaan pada setiap desain. Namun, pada stabilitas lereng, desain alternatif 2 paling stabil dibandingkan dengan desain eksisting dan desain alternatif 1 dengan angka keaman di bagian hulu sebesar 4,628 dan di bagaian hilir sebesar 4,074. Dan ditinjau dari ketersediaan material yang letaknya paling dekat dengan lokasi proyek, desain alternatif 2 dapat dikatakan paling efektif karena material yang dibutuhkan semuanya tersedia pada 3 (tiga) quarry (Quarry Bendo, Quarry Bondrang, Borrow Area Ngindeng) dengan jarak paling jauh (quarry Bondrang) hanya 3,5 km dari lokasi proyek.
================================================================================================
This study used three dam designs including an existing design, an alternative design I, and an alternative design II. In all of the designs, MAB +223.11, MAN +221.30 and Rapid Lowness were determined from the condition of MAN to the Mercu Intake +198.00. The design analysis used the Geo-Studio 2012 auxiliary program. It produced an analysis in the form of a seepage pattern, a seepage speed, a seepage discharge and a safety figure on the upstream and downstream slopes where the numbers refer to the SNI 2016.
The results of the design analysis showed that the occurred seepage was not too much difference in each design. However, on slope stability, the alternative design II was the most stable design compared to the existing design and the alternative design I with 4.628 in upstream security numbers and 4.074 in downstream area. In terms of the closest material availability to the project location, the alternative design II could be said as the most effective design because the needed material was all available in three quarries (Bendo Quarry, Bondrang Quarry, and Ngindeng Borrow Area) with the longest distance (Bondrang Quarry) only 3.5 km from the project location.
