- Foundation plan to shore up machine load, the foundation system influenced by shaking load, the load caused by imbalance machine force and static system load (foundation and machine). Reminding the change shaking load, according to time and tempo function which long and working in repetition, it caused the structure would be difference compared with structure which accepted static load only. Foundation type used in this planning was block type foundation where in its calculation to find out the condition fulfilled dimension, using trial and error. In general, the foundation weight was the multiple times of machine weight (Prakash dan Puri, 1969). Foundation attitude which got dynamic load caused by machine was moving into vertical, horizontal, combination and torque. In this calculation, dimension which able to resist the machine dynamic load by length 9,2 m, wide 4,8 m and deep 2,8 m, where direction amplitudo z = 0,127 mm, amplitudo direction x = 0,142 mm, amplitudo direction y = 0,19 mm, amplitudo vertical combination = 0,0083 rad, amplitudo horizontal combination = 0,0027 rad and turque amplitudo = 0,00159 rad, smaller than conditioned amplitudo = 0,8 mm. Existing supporting force = 28,226 t/m2, maximum decreasing= 10 mm and tension worked under of foundation was = 7,65 t/m2 smaller than qizin = 9,41 t/m2.
