## Abstract
Abstract Breakwater is a structure that builds parallel to the coast, and located within some distance from the coastline. The breakwater that is currently and widely used is Rubble Mound Breakwater; a large dimension coastal structure with also come in high price. Due to this matter, a Hanging Sheet Pile type breakwater can be one of good solution. This research was conducted at Ocean Technology Laboratory, Faculty of Engineering, Universitas Hasanuddin, in a flume thank with 1:25 model scale, and equipped with wave generator and probes as measurement apparatus. The purpose of this study is to identify the effect of wave parameters (H i /gT 2 ) and structure parameters (draft relative, s/d) on fluctuated wave transmission coefficients produced. The waves are in the form of irregular waves that generated using JONSWAP spectrum. There were 5 variations in wave height (H) and wave period (T), while variations of structure in the form of draft (s) are in 3 variations. The results of this study indicate that the value of K t will decrease when H i /gT 2 value increase; so that the greater the value of s/d, the smaller value of K t will be.
