The objective of this research is to investigate the characteristics of an organic nanoparticle produced from Gmelina wood bark using ball milling with liquid nitrogen treatment. In this study Gmelina wood bark was converted into nanoparticles using the ball milling method for 96 h and then filtered using four types of sieves (T77, T90, T120, and T200). These nanoparticles were characterized by particle size, morphology, chemical components, functional groups, and crystallinity using TEM, SEM, SEM-EDS, FTIR and XRD. The process resulted in nanosized organic material produced from Gmelina wood bark, with diameter sizes less than 1000 nm. The existence of carbon, oxygen, potassium, and calcium were observed from the SEM-EDS analysis. The FTIR analysis showed the presence of C-O-C in a plane and symmetric band at 829 cm−1 for the nanoparticle produced from the T200 sieve type, while not observed in the nanoparticle produced from T77, T90 and T120 of sieve types. The crystalline structure as obtained from the XRD analysis contained calcium oxalate hydrate (C2CaO4.H2O) with a 20 nm crystalline diameter size that was produced using the T77 and T200 sieve types.
