Abstra ct : Preparation of Barium Titanate thin film (BaTiO3) has been done on Quartz substrate using sol gel method with spin coating technique. A thin film BaTiO3 wase made with a mole variation of 0.4 mol and 0.8 mol at a rotation speed of 3000 rpm. The samples were annealed at 400 ° C with 30 minutes stand-up time and at 900 ° C with 2 hours stand-up time and a heating rate of 5 ° C per minute. Characterization of optical properties samples was performed using UV-Vis spectrometers and characterization of microstructure samples using X-Ray Diffraction (XRD). The particle size was calculated by Scherer's formula. Based on the results of the analysis it was found that mole variation of the solution influenced the absorbance value, intensity, crystality level and BaTiO3 thin film particle size. The greater mole of BaTiO 3 solution the higher then absorbance value. The fewer then number of layers the greater then diffraction peak intensity. More number of layers the greater the level of crystallinity and particle size. Abstra k: Pembuatan lapisan tipis Barium Titanat (BaTiO 3 ) telah dilakukan diatas substrat Quartz menggunakan metode sol gel dengan teknik spin coating. Lapisan tipis BaTiO 3 dibuat dengan variasi mol 0.4 mol dan 0.8 mol pada kecepatan putar 3000 rpm. Sampel diannealing pada suhu 400 o C dengan waktu tahan 30 menit dan pada suhu 900 o C dengan waktu tahan 2 jam dan kenaikan suhunya 5 o C per menit. Karakterisasi sifat optik sampel dilakukan menggunakan spektrometer UV-Vis dan karakterisasi struktrur mikro sampel menggunakan X-Ray Diffraction (XRD).Ukuran partikel dihitung dengan formula Scherer. Berdasarkan hasil analisis didapat bahwa variasi mol larutan mempengaruhi mempengaruhi nilai absorbansi, intensitas, tingkat kekristalan dan ukuran partikel lapisan tipis BaTiO 3 . Semakin besar mol larutan BaTiO 3 maka semakin tinggi nilai absorbansinya. Semakin sedikit jumlah lapisan maka intensitas puncak difraksi semakin besar. Semakin banyak jumlah lapisan maka semakin besar pula tingkat kekristalan dan ukuran partikel .
