Abstract

All living things need O2 for breathing. O2 was functioned to establish the metabolism process or the exchange of substances which were produced the energy for the growth and reproduction. The purpose of this study was to analyze the spatial distribution of O2 content at the region of Gili Iyang by using chemical electro method. The content of O2 analyzing was identified by vegetation index value using Enhanced Vegetation Index (EVI) algorithm through Landsat 8, and it relationship with Digital Elevation Model (DEM) data. The result of the study was obtained the average of oxygen content at Gili Iyang of 20.9 %. The relationship between EVI and O2 showed the low correlation with R2 = 0.2236. The low correlation was also shown in relation between DEM and O2 content (R2 = 0.1962). It means there was not relationship between EVI, DEM and O2 content in the Gili Iyang.
