The effectiveness of the palm kernel separation process is of paramount significance, as it directly influences the quantity of palm kernels obtained. This efficiency forms the core of the decision-making process when considering how to best use palm kernel shells, which are a byproduct of the palm oil industry. These versatile shells have various applications, including their role as a fuel source, their use in producing activated carbon, and their utility as an alternative material in lightweight concrete. The primary aim of this investigation is to examine and enhance the efficiency of this innovative segregation technique, with a specific focus on identifying the optimal conditions for achieving effective segregation, particularly the ideal concentration of salt (NaCl) in a batch process. The research methodology comprises a wellstructured series of steps designed to systematically evaluate the segregation process. In the initial stages, samples of palm kernel and shell were collected from a local palm oil industry and meticulously prepared for experimentation. Subsequently, salt solutions with varying saturation percentage of salt solution beetwen 12 g/L and 380 g/L were prepared. As the samples were immersed in the solution, the denser palm kernel shells settled at the base, whereas the lighter palm kernels rised to the top, simplifying the separation of these two elements. The highest level of segregation efficiency was achieved at the 380 g/L of Consentration of salt solution. This suggested method offers advantages, including the capability to achieve a 100% separation of palm kernel and palm kernel shell. © Published under licence by IOP Publishing Ltd.
