      Abstract
      ASIH. Sruktur kristal dan sifat optik di dalam keramik SrTiO3 didadah Ferrum (II) Asetat. Dibimbing IRZAMAN dan ARDIAN ARIF SETIAWAN. Keramik SrTiO3 dengan variasi konsentrasi pendadah Fe(CH3COO)2 (0%, 0.5%, 1%), telah berhasil dibuat menggunakan metode Solid State Reaction. Keramik SrTiO3 di-annealing dengan kelajuan suhu sebesar 1,6°7C/menit dan pada suhu 85°C ditahan selama 8 jam, lalu mengikuti proses pendinginan hingga suhu kamar selama 13 jam. Keramik SrTiO3 didadah Fe(CH3COO)2 (0%, 0.5%, 1%), dikarakterisasi menggunakan XRD, Spektrofotometer FTIR, dan Spektrofotometer UV-Vis sehingga menghasilkan parameter kisi a sebesar 3,909 Å; 3,906Å; dan 3,899Å dengan struktur kristal berbentuk kubus (a=b=c). Hasil analisa menggunakan perangkat lunak MAUD sebagai data pembanding didapatkan parameter kisi a sebesar 3,899Å. Analisa hasil menggunakan perangkat lunak MAUD diperoleh visualisasi struktur kristal kubus. pada keramik SrTiO3 Menentukan nilai Optik Transversal (TO) dan Optik Longitudinal (LO). Hasil nilai energi bandgap secara berturut-turut sebesar 3,54; 3,48; 3,23 eV.
       
      ASIH. Crystal structure and optical properties of Ferrum-dopped SrTiO3 ceramics dopped. Supervised by IRZAMAN dan ARDIAN ARIF SETIAWAN. SrTiO3 Ceramic with the variation of Ferrum doping concentration (0%, 0,5%, 1%) has been successfully made on Solid State Reaction method. SrTiO3 ceramic was annealed with an increase in temperature of 1,67°C/minute and at 850°C for 8 hours, then follow the cooling process to room temperature for 13 hours. SrTiO3 ceramic with Ferrum doped (0%, 0.5%, 1%, was characterization using a XRD, ectrophotometer FTIR and spectrophotometer UV-Vis, The result of the lattice parameters obtained based on XRD characterization are 3,909 Å; 3,906 Å; and 3,899 Å with a cubic crystal structure (a = b = c). The results of the analysis using MAUD software as comparison data obtained lattice parameters a of 3,899 Å. Analysis of the results using MAUD software obtained visualization of the cube crystal structure on the SrTiO3 ceramic. Determine the Transversal Optic (TO) and Longitudinal Optic
