The damage or deterioration of the material due to reaction with the environment is called corrosion. The corrosive of soil can cause natural disasters such as landslides. Soil corrosivity is a serious problem in industrial and infrastructure activities. Soil corrosivity is also a problem at PT. IPMOMI, because of the large number of metal pipes that are planted underground which functions to drain fluid in the form of seawater as the main material for steam production. PT. IPMOMI wants to install metal pipes underground, Therefore PT. IPMOMI requires information about the status of soil corrosivity at that location. To overcome soil corrosivity, PT. IMOMI will install cathodic protection on the soil with high corrosivity. One of the efforts to deal with this problem is by mapping the subsurface corrosion zone. Before mapping the corrosion zone, it is necessary to know the level of soil corrosivity whether it is very high, high, medium, low, or very low. So that to determine the level of soil corrosivity whether very high, high, medium, low, or very low, a classification method is needed. In this study, the classification method used is the nonparamteric classification method, namely K Nearest Neigbors. The results of classification accuracy were 83.3% and variable chargebility had a higher contribution than the depth level in the classification model.
