Abstract

Kernel recovery plant is one of main divisions in palm oil mill industry. The main function of the kernel recovery plant is to process nut separation to recover kernels. The kernel recovery plant consists of several machines that produce an excessive noise. This working condition can lead to discomfort and hearing loss to workers. The objective of this study is to determine workstations that produce noise at the kernel recovery plant. Consequently, this study assesses the noise level of each workstation. The third objective is to design a noise insulator for ripple mill machine at the kernel recovery plant. A questionnaire survey has conducted among the workers to determine workstations that produce noise at the kernel recovery plant. A sound level meter was applied to assess the noise level at each workstation. The ripple mill machine has been identified as main contributor to excessive noise. This study developed a noise insulator prototype for ripple mill machine using combination of oil palm fiber and cardboard. A pre-post noise assessment proved that the prototype of noise insulator can reduce the noise level by 14.4%. Based on this finding, this study concluded that application of noise insulator made of oil palm fiber and cardboard is effectively reduce the noise level at the kernel recovery plant.
