This study sought to determine the relationship between cracking energy and palm kernel nut nominal diameter and their masses. Large sample of palm kernel nut were cracked using the static impact method, after characterization of the kernel based on the nominal diameter into d<12mm; 12mm≤d<15 mm; 15mm≤d<17mm; 17mm≤d<19mm; 19mm≤d 20mm and d>20mm.

the nut [1]. The palm kernel is the palatable seed of the oil palm organic product. The natural product yields two unmistakable oils: palm oil and palm kernel oil. The palm oil is gotten from the external piece of the natural product, while the palm kernel oil is gotten from the nut. The oil palm tree is an enduring plant.

The fruit from the betel nut palm tree is the areca nut. The mature palm nuts are brown and egg-shaped and measure up to 2" (5 cm) long. Although called a nut, this brown palm fruit is a hard-shelled drupe. When ripe, the outer layer develops a hard, fibrous shell like a nut. The areca palm nut is commonly called the betel nut.
