× Membrane films PVA were grown on Pt electrodes using Spin Coating method. The electrodes were made using Ladd evaporator research with 1.7cm depocite distance, 5 x 10-6 torr pressure, minimum slith width of wire cut filter ( 1mm ). Electrodes resistance are (1.620 ± 0.315) W, (1.640 ± 0.295) W and (1.560 ± 0.254) W. The act of growing PVA used 1.5 minute spin time, used water as soluble with three concentrate variation of PVA, that are 33%PVA, 20%PVA, 14%PVA. At 33%PVA concentrate, the maximum absorbance is 3.3, resistance PVA is ( 1.0 ± 0.1 ) x 108 W and angular velocity optimize is 4000rpm. At 20%PVA concentrate, the maximum absorbance is 2.3, resistance PVA is ( 2.3 ± 0.2 ) x 108 W and angular velocity optimize is 1500rpm. At 14%PVA concentrate, the maximum absorbance is 2.1, resistance PVA is ( 7.0 ± 0.8 ) x 108 W and angular velocity optimize is 1250rpm. More concentrad of PVA concentrate, the angular velocity optimize is more faster, and the resistance became smaller. Key words : Spin coating, Evaporator, PVA, Pt, Absorbance, Resistance
