One-dimensional (1-D) zirconia nanomaterial (ZrO2) is a promising material fo many applications, such as for sensors, catalysts, and as a reinforcing element in composites. The template-precursor method is one way of making 1-D ZrO2 nanomaterial. This research focuses on the synthesis of one-dimensional ZrO2 nanomaterial based on Zr(OH)4 precursors with nanocellulose-assisted. Sugarcane bagasse and pineapple leaf as a source of nanocellulose are used because it has a lot of cellulose content compared to other biomass. Isolation of sugarcane bagasse nanocellulose and pineapple leaf using strong acid hydrolysis (H2SO4) method. Microstructure characterization of Transmission Electron Microscopy (TEM) of sugarcane bagasse nanocellulose showed fibers with 20-50 nm in diameter, while nanocellulose pineapple leaf shows fibers with 10-40 nm in diameter. 1-D ZrO2 nanomaterial is made in pH 3 and calcination temperature of 800oC. Spectra test results (FTIR) showed an interaction between the precursor Zr(OH)4 with the sugarcane bagasse nanocellulose template or pineapple leaf. They forming –ZrO bond and typical monoclinic –ZrO bond at wave numbers below 750 cm-1. The XRD of 1-D ZrO2 nanomaterial produced has a tetragonal-metastable phase and a monoclinic phase. While ZrO2 microstructure without nanocellulose-assisted has a bulk form of sphere and cubic. Sugarcane bagasse nanocellulose template produces one-dimensional ZrO2 nanomaterial in the form of nanorods but not yet perfect for growth. Meanwhile, the pineapple leaf nanocellulose template produces a better microstructure of 1-D ZrO2 nanomaterial in the form of nanorods with 30-60 nm in diameter and 100-400 nm in length.
