Clustering of disaster prones areas in Java Island

What is it about?

Indonesia is one of the countries that has a high level of disaster risk index. This is caused by many factors, including geographical location, climate and weather conditions, and population density in some regions. Java Island is an area that has a high population density, especially in the capital city of Jakarta. In addition to its geographical location, Java Island has a higher disaster intensity than other regions. The high intensity of natural disasters that occur is in line with the level of casualties and losses caused. This is certainly a responsibility and a concern for all of us to be able to understand the importance of disaster mitigation steps that need to be taken to minimize casualties and material losses. Therefore, clustering is carried out to group and see which areas have the highest to lowest level of disaster vulnerability, especially on the Java Island based on the number of events, the number of victims, and the amount of damage to facilities.

Why is it important?

Furthermore, the relationship between the level of disaster vulnerability in each region and the potential risk of losses incurred will be analyzed using the K-Means Clustering method. The results obtained are for the flood disaster category obtained two clusters, and the category of disasters such as landslides, tornadoes, and earthquakes as many as three clusters. The most flood-prone areas are West Java, and Jakarta with the highest level of potential loss in Jakarta. The most prone areas for landslides and earthquakes as well as having the highest level of potential loss are West Java and for the tornado disaster the most prone area with the highest level of potential loss is Central Java.
