Abstract

The properties of barium titanate (BaTiO₃) nanoparticles synthesized with rambutan leaf extract (Nephelium lappaceum L.) were analyzed using Fourier transform infrared spectroscopy (FTIR) characterization techniques. Rambutan leaf extract contains bioactive compounds that have the potential to enhance unique physical and chemical properties. This study aims to analyze the properties of the nanoparticles and to characterize the functional groups present in BaTiO₃ nanoparticles synthesized using rambutan leaves. The nanoparticle synthesis process involved extraction, followed by the preparation of a BaTiO₃ solution and doping. The FTIR spectrum displayed characteristic peaks identifying the presence of functional groups. The results indicated that the region 3500 – 3200 cm^-1 corresponds to O–H groups (alcohol and phenolic), the region 1700 – 1600 cm^-1 to C=O groups (carbonyl), the region 1600 – 1500 cm^-1 to C=C groups (alkene), and the region 1200 – 1000 cm^-1 to C–O groups (ether). Each functional group exhibits distinct properties.
