Abstract
The aim of this study was to determine the effect of particle size and pressing pressure on the quality of biopellets from oil palm dregs. The pressing pressure used is 0.4882 kg/cm², 0.9764 kg/cm², 1.4647 kg/cm². Particle size passes mesh 10, passes mesh 20, and passes mesh 40. Biopellets are made using a hydraulic shop press and produce biopellets with a length of 2.5 cm and a diameter of 1.2 cm. The quality of the biopellets was assessed by SNI 8021: 2014. The results of the study showed hemicellulose with a value of 25.7% -34%, cellulose with a value of 27.1% -47.6%, lignin with a value of 7.2% -10.2%. Water content with a value of 6.49%-9.39%, ash content with a value of 5.00%-7.32%, heat with a value of 4380.43 cal/g-4621.86 cal/g. The quality of the biopellets meets the standard requirements of SNI 8021: 2014, except for the ash content. The best results were obtained for particles with a mesh size of 10 with a pressure of 4621.86 cal/g and a positive added value > 0, namely 38.91%. Keywords: Biopellets, palm oil, value added.
