Abstract

Floating breakwater biasa diaplikasikan sebagai solusi alternatif terhadap fixed breakwater konvensional dan dapat digunakan secara efektif di daerah pesisir pada lingkungan dengan gelombang yang ringan, kondisi tanah yang kurang baik, kedalaman laut yang cukup dalam, dan fenomena erosi pantai yang intens. Karena struktur floating breakwater merupakan struktur terapung, digunakan mooring system untuk menjaga floating breakwater tetap pada posisinya. Penelitian ini bertujuan untuk mengetahui tegangan mooring yang terjadi pada tiap tali mooring dengan pengujian model fisik dalam skala laboratorium. Peneltitian dilakukan pada floating breakwater tipe pontoon dan floating breakwater tipe gergaji berpori. Dalam penelitian ini didapatkan bahwa pada floating breakwater tipe gergaji berpori, tegangan maksimum terbesar terjadi pada kombinasi sudut mooring 30⁰ dan elevasi muka air 45 cm yaitu 3,983 N sedangkan tegangan maksimum terkecil terjadi pada kombinasi sudut mooring 60⁰ dan elevasi muka air 41 cm yaitu 0,731 N. Floating breakwater tipe pontoon juga memberikan hasil yang sama dimana kombinasi sudut mooring 30⁰ dan elevasi muka air 45 cm memberikan nilai tegangan maksimum tertinggi sebesar 4,913 N sedangkan kombinasi sudut mooring 60⁰ dan elevasi muka air 41 cm memberikan nilai tegangan maksimum terkecil sebesar 1,273 N. Selain itu, floating breakwater tipe gergaji berpori dapat memberikan nilai tegangan lebih kecil yaitu berkisar antara 7 – 50 persen.============================================================Floating breakwater is commonly used as an alternative solution to conventional fixed breakwaters and can be used effectively in coastal areas in environments with relatively small waves, poor soil conditions, deep sea depth, and shore with intense erosion rate. Because floating breakwater is a floating structure, mooring system is used to maintain the floating breakwater stay in its position. This study aims to determine the mooring tension occurs on each mooring rope on a laboratory scale by physical model tests . The research was conducted on pontoon type floating breakwater and porous saw type floating breakwater. In this study it was found that on a porous floating breakwater type, the greatest maximum tension occurred in a combination of 30⁰ mooring angle and 45 cm water level elevation which was 3,983 N while the smallest maximum tension occurred in a combination of 60⁰ mooring angle and 41 cm water level elevation which was 0,731 N. Pontoon type floating breakwater also gives the same results where the combination of 30⁰ mooring angle and 45 cm water level elevation give the highest maximum tension value of 4,913 N while the combination of 60⁰ mooring angle and 41 cm water level elevation give the smallest maximum tension value of 1,273 N. Porous saw type floating breakwater can provide a maximum tension between 7 - 50 percent smaller than porous type floating breakwater.
