| Summary: | Carbon steel, which is commonly used as a construction material, cannot
be separated from atmospheric corrosion damage, especially in Southeast Asia.
That region has a tropical climate with high temperature, relative humidity, wind
speed, and other weather factors. Many researches are conducted to predict the
corrosion rate so the problem can be prevented, but with conventional
experciment method it will spend much time and cost. One of the methods to
predict the corrosion rate is machine learning. To make an optimal model, first
the environment factor and corrosion rate data were collected. Then the dataset
was analyzed so the correlation between parameters was known. This machine
learning process uses Gradient Boosting and Decision Tree Regression model,
and their accuracy and error calculation are pretty similar. But from the validation
model and prediction, Gradient Boosting is more sensitive with input data. The
prediction of corrosion rate in several places in Southeast Asia are carried out,
and the result of corrosion rate for Gresik 18,4; Bandung 15,7; Phuket 17,8; Phra
pradaeng 16,0; and Yangon 16,1 all in ?m/year. To make the machine learning
prediction more accurate, it is necessary to collect more good quality data. |
