    Abstract
    In framework of effort to overcome the coastal damage, this article try to lay open the alternative choice form of construction which serve later the purpose of reduce water wave before arrive into the surf zone. The construction model test has six tooth of saws which form angle 0O38’37” and installed in the water level equal to flatten the water, ten, twenty, three centimeter water dept, water wave high is given on model test have four type between 5 up to 14,8 cm with regular waves type. This experiment could result have to reduce water wave come from deep water before arrive at coastal, with approach refraction effect principal from tooth of saw model test. Result of study with graph analysis depends on relation between independent variable wave hydraulics with transmission coefficient and relation between independent variable water level on the weir of the model test with hydraulics with transmission coefficient(KT), have result make up a function of wave slope and water level on weir of the model. From the six tooth saw model test with angle 0O 38’ 37” have resulting is best for reduce water wave and capable reducing 55%- 75% transmission wave. Effect Orthogonal wide wave (B2) of the angular shape the tooth saw that happened good enough between 2 – 3 times wide spread of the model test (L) or (B2/L) equal to 200%- 300% specially the water level on the weir (h2/d)= 0.125, so that of course will made coastal protected happened abration/ erosion and even coastal line will be able to experienced of acresi.
