The improvement quality of oil palm trunk could be done by compression. As based on to determining of compressing level, it was need to study the density distribution and stress-strain curve of oil palm wood. The three of oil palm trunk at 23 years old were cut. The specimen for density distribution was taken from 1 m, 3 m and 5 m of height of oil palm wood with dimension 2 cm x 2 cm x 2 cm. The interval of it was 2 cm from the outer on the left to the right side. Then the specimen for stress-strain curve was taken from 1 m of height with interval of 2 cm from the outer to center of trunk. These specimens were taken at water saturated conditions. The result showed that density of oil palm wood was around 0.19-0.43 g/cm 3 . The density distribution at outer side was high, then decreasing toward the center of trunk. The compressing level increased from the outer side to the center of oil palm trunk. In the outer side of oil palm trunk can be compressing until 58% and the center side can be compressed until 71%.
