THE CHARACTERISTICS MEMBRANE PVA-ENZYME AND COATING PVC-PLATICIZER WITH SEM-EDX

This study aims at PVA membrane-coating enzyme characteristics PVCplasticizer through the SEM absorption spectrum and completeness of elements using EDX. The method used membrane immobilization at the indicator electrode derived from Wolfram material. Selection phase of indicator electrode by dyeing tungsten electrode with PVA - enzyme, then coating with PVC - plasticizer and dyeing tungsten electrode using PVA – enzyme, then in coating with PVC – plasticizer. Membrane and electrode membrane are varied by respectively (1) PVA 0.5040 g + enzyme, (2) PVA 0.0350 g + enzyme, (3) PVA 0.5040 g + enzyme and coating I, (4) PVA 0.0350 g + enzyme and coating I, (5) PVA 0.0350 g + enzyme and coating II. The approach used for analysis is the morphology and EDX
spectrum analysis. The result of the research was obtained with a 0.0350 g PVA membrane of the best Coating II Coating on 2x 1x coating dyeing, to be shown by difference morpologi of coating II and coting I, where coting II completely flatten at the indicator electrode.
