Abstract
ABSTRACT Seed germination is quite difficult, because the seeds have a thick and hard shell and dormancy. To accelerate germination, it is necessary to shell removal for seed germination. The objective of the research is to machine design for the shell removal of palm seed.. Cracking of shell palm seed required a force of 0.8-3.0 kN. The working mechanism of the palm kernel shell crusher applies to the compressive force. The force is produced from two cylinders rotating in opposite directions. The oil palm seeds are divided into 3 parts based on the size of oil palm seed in 3 dimention of large, medium and small. The testing of cracker machine is a loose shell of the kernel, the kernel is not defective and is mechanically defective. The result of this cracker testing is that the shell still attaches to the kernel for small, medium and large seed sizes of 30%, 23% and 20%, no kernel at shells of 52%, 61% and 64% and defective kernels of 18% 14% and 16%. Kernels that can be germinate with small, medium and large seed sizes are 70%, 77% and 80%. The cracker testing for one cylinder are that the shell still attaches to the kernel 10%, damage kernel 4% dan whole kernel 86%. Keywords : shell, cracking, seed, germination, and kernel
