Advances in nanotechnology today vary widely when viewed from the background of its application, the volume of nanoparticles has become the focus of researchers in the last decade. Hybrid nanoparticles are advances in the world of nanotechnology in which nanoscales of different sizes are added to each other using either the one-step method or the two-step method. This study intends to examine the hybrid titanium oxide-aluminium oxide (TiO2-Al2O3) nanoparticles by looking at the ratio of the volume to mass of different nanoparticles with different proportions of TiO2 (80%) and Al2O3 (20%) nanoparticles added with basic liquid with a fixed volume concentration of 0.1%. Ultrasonic testing and magnetic stirring ensure the stability of nanofluids as well as a way to synthesize nanofluids. Characterization of hybrid nanoparticles using x-ray diffraction (XRD), fourier transform infrared (FTIR) and scanning electron microscopy (SEM) analysis to determine the phase of the crystalline material and see the morphology of the microstructure. The incorporation of TiO2+Al2O3 nanoparticles when viewed from the thermal conductivity and viscosity testing efficiently shows that the thermal conductivity has increased compared to the decreased viscosity, therefore hybrid nanofluids have a potential influence on the heat transfer system for increasing thermal conductivity and low viscosity. © 2024 American Institute of Physics Inc..
