Abstract

Dalam perancangan desain breakwater, salah satu metode yang dikembangkan
ialah metode konvensional. Metode ini didasarkan pada konsep beban, dimana
beban desain tidak boleh melebihi daya tahan (carrying capacity) struktur. Beban
desain itu sendiri dapat diidentifikasi dengan menggunakan cara probabilistik,
contohnya seperti mencari nilai rata-rata dari periode ulang gelombang 60 tahun
sehingga diperlukan data gelombang yang nantinya akan diolah lebih lanjut.
Sebagian besar formula desain yang tersedia hanya memberi hubungan antara
karakteristik gelombang dan beberapa respons struktural, seperti run up, limpasan
(overtopping), kerusakan lapisan pelindung (armour layer), dan lain-lain. Dalam
Tugas Akhir ini, dilakukan analisa keandalan terhadap stabilitas hidraulik dengan
simulasi Monte Carlo. Formula yang digunakan dalam perhitungan stabilitas
hidraulik yaitu formula Hudson dan Van Der Meer. Hasil yang didapatkan adalah
struktur breakwater yang ada di PLTU Pacitan sudah memenuhi kriteria desain
stabilitas hidrolik sesuai dengan formula Hudson dan Van Der Meer dengan
keandalan diatas 98,8% (Hudson), 95,12% (VDM). Untuk keandalan desain
penulis dengan batu pelindung Dolos, BPPT Loc dan Tetrapod masing-masing
memiliki nilai keandalan sebesar 94%, 94,03%, dan 94,1% (Hudson) serta
79,28%, 79,11%, dan 78,94% (VDM).
======================================================================================================
In calculating of breakwater design, one of the methods developed is conventional
method. This method is based on the concept of load, where the design load
should not exceed the carrying capacity of the structure. The design load itself can
be identified using probabilistic means, such as looking for the average value of a
60-years wave return period so that wave data is needed that will be further
processed. Most of the design formulas available only provide a link between
wave characteristics and some structural responses, such as run up, runoff
(overtopping), armor layer damage, etc. In this Thesis, a reliability analysis of
hydraulic stability is performed with monte carlo simulation. The formulas used in
hydraulic stability calculations are the Hudson and Van Der Meer formulas. The
result is the breakwater structure in Pacitan Power Plant already meets the
hydraulic stability design criteria in accordance with Hudson and Van Der Meer
formula with reliability 98.8% (Hudson), 95.12% (VDM). For author design
reliability with Dolos protective stones, BPPT Loc and Tetrapod have reliability
values of 94%, 94.03%, and 94.1% (Hudson) and 79.28%, 79.11%, and 78.94%
(VDM) respectively.
