## Abstract
The aims of this study are to analyze the effect of acidity and rotational speed in the synthesis of TiO 2 using the sol-gel method and to analyze the morphology of synthesized TiO2 nanoparticles and commercial TiO 2 using XRD to produce semiconductors for Dye-Sensitized Solar Cell (DSSC) applications. The sol-gel method was used to synthesize TiO 2 Nanoparticles. Titanium tetra-isopropoxide (TTIP) was used as a precursor with the variable of the magnetic stirrer rotation speed of 500, 1000 and 1500 rpm. Acidification was achieved by adding acetic acid to Sol-gel solution to produce a pH number of 1, 2, and 3. Nanomaterial was observed with an optical microscope and X-ray Powder Diffraction (X-RD) to determine the morphology and phase of TiO 2 crystalline. The results showed that the rotational speed and acidity level of the Sol-gel solution ware played an important role to get the best form of a nanoparticle. At a rotation speed of 1500 rpm with pH 3 and 1000 rpm with pH 2 ware shown characteristics similar to commercial TiO 2 . In addition to that, the results of XRD characterization of synthesized TiO2 was shown a crystal phase of anatase structure with 18,046 nm crystal size compared to commercial TiO 2 with anatase structure and crystal size of 15,554 nm.
