The construction sector still has a low achievement in safety issues. Fatal accident rate in construction is higher than average rate in other industries. Because of it, need some attention to minimize the rate of accident in construction. This research examined the key factors of safety planning in the pre-construction stage, and it was based on the theories of accidents causation having the upstream approach. Some theories were: Constraint-Response Theory (CR); Construction Design Management (CDM), and the Process Protocol (Pp). This research broke down the three theories above (CR; CDM; Pp) into the concept of the key factors of safety planning in pre-construction. Then, the concept was verified by construction practitioners and academician, using Delphi method three rotations. During the verification, from the first to the third round, there were reduction and the addition concept and language appropriateness. The findings of this research were assessment models of maturity safety planning in the pre construction stages. There were two models, the model of "radar chart" or MISAP 1 and the model of "worksheet" or MISAP 2.

Protection of beaches for tourism development, protection planning in addition to aiming to keep the damage to the beach will also need to think about the authenticity and beauty of the beach area . Building protective beaches that can meet these objectives include low threshold breakwaters (submerged breakwater). Some of the excessuse of low threshold breakwaters are: 1. No disturbing beauty of the beach; 2. because construction is under water, then when the wave comes partially absorbed wave energy, will be partially reflected, and the rest will be transmitted; 3. can become breeding grounds for fish, because the construction is hollow. The disadvantages are: 1. requires a large stone with a large number, 2. in the assembly requires a supporting infrastructure such as transport equipment, long bridge, lifting equipment etc, thus requiring a lot of cost. Based on that research conducted by the title of the transmission and reflection of waves on double sumerged breakwater. Methodology of research, conducted with with physical models, and then continued with theoretical studies in order to obtain the equation for calculating the coefficient of wave  transmission and wave reflection coefficient. The results showed that to calculate the magnitude of the coefficient of wave transmission and wave reflection coefficient can be approximated by the following equation: , .
