Implementation of Inverse Distance Weighting (IDW) and Kriging method for distribution pattern humidity and temperature data on weather changes in the Bangka Islands

Abstract

Weather is one indicator of climate change on Earth that affects various aspects of life. The role and influence of the weather are also very influential on the elements that influence it. Moreover, the air temperature on Bangka Island has changed from previous years. This research is used to look at the pattern of temperature and humidity distribution in the Bangka Island region by implementing the IDW and Kriging methods. This research provides information on temperature and relative humidity changes from 2019 to 2021. Based on the results of the IDW and the Kriging method, an increase in temperature on Bangka Island occurs in the downtown area to the south of Bangka Island. As for relative humidity, there tend to be more changes from the northeast to the southwest of Bangka Island. In general, there is no significant difference in the implementation of both methods, but if we look at the prediction errors, it can be said that the kriging is better than the IDW method. With this research, it is hoped that it can become a consideration for related parties related to climate change in the Bangka Island Region.
