The purpose of this research is to obtain optical energy band gap value by adopting Tauc plot method with various composition and temperature. Obtaining of such information could be through identifying the degree of absorbance, degree of transmittance, the extent of refractive index, the usage of thin film and its quantified coefficients. Subsequently, the optical properties of thin film are characterized by using Ultraviolet-Visible Spectrophotometer with a thin film of Ba<sub>1-</sub><sub>x</sub>Sr<sub>x</sub>TiO<sub>3</sub> subjected to temperatures of&nbsp; 650ºC. Upon subjected to temperature stated above, the wide energy band gap optical thin film Ba<sub>0,6</sub>Sr<sub>0,4</sub>TiO<sub>3</sub> is in the range of 2.0 eV for Ba<sub>0,5</sub>Sr<sub>0,5</sub>TiO<sub>3</sub> is in the range of 1.55 eV and for Ba<sub>0,4</sub>Sr<sub>0,6</sub>TiO<sub>3</sub> is in the range of 2.0 eV.</p> <p><strong>Keywords</strong>: <em>Thin Film BST, Composition, Temperature, Energy Band Gap.</em></p&gt;}, journal={PROSIDING SEMINAR NASIONAL FISIKA (E-JOURNAL)}, author={Dewi, Rahmi and Krisman, Krisman and Hidayat, Taufiq}, year={2016}, month={Oct.}, pages={SNF2016-MPS} }
