Abstract:	This research aims to obtain new foundation dimensions and also use rubber dampers as the most straightforward solution in overcoming the problem of excessive vibration in the system, according to permitted standards. From the calculation analysis, it can be concluded that to overcome the excess vibration that occurs can be done by enlarging or changing the shape, dimensions of the foundation, and damping (c) of the foundation. The magnitude of the vibration amplitude in the driving motor foundation system on this ship is 0.078 mm for the SR1110 type and 0.069 mm for the S1100 type and the vibration level that occurs is stated to exceed the limits still. With the change in the dimensions of the new foundation, the amplitude of the SR1110 type diesel engine becomes 0.0245 mm and the S1100 type becomes 0.0238 mm. A comparison of these results with the Barkan table shows that the value of this amplitude is still within the allowable limit of less than 0.02 mm to 0.05 mm.
