Abstract This study focuses to analyze mechanical properties of Salak Pondoh fruit on maturity periods through non-linear viscoelastics model from Lichtensteiger. Using a pneumatics impacter provided by piezoelectrics force sensor BK 8200 and acceleration sensor BK 4374, the history of the impact force and impact acceleration is recorded on microcomputer system. Thirty-three Salak Pondoh fruits with seven maturity levels were evaluated through impact impulse on one side. The deformation velocity and deformation level of Salak Pondoh fruit due to impact are analyzed and differentiated from impact acceleration data. The result of this study shows impact force, deformation, and deformation velocity histories are able to describe levels maturity of Salak Pondoh .
