Clustering of Planted Area, Harvested Area, and Rice Production in Each Village of Jember Regency Using K-Means Clustering and the Davies Bouldin Index
Abstract
Rice (Oryza sativa L.) is a cultivated crop that serves as the primary staple food for the majority of Indonesia’s population. East Java Province is one of the regions with the highest rice production in the country. Therefore, increasing rice production is essential to meet national food demands. This study aims to classify villages in Jember Regency based on the variables of planted area, harvested area, and rice production, using data obtained from the official publications of the Jember Regency Central Bureau of Statistics for 2022 and 2023, covering a total of 248 villages. The data were processed using the K-Means Clustering algorithm, followed by determining the optimal number of clusters using the Davies Bouldin Index. The clustering results were visualized in an interactive web-based map through a Geographic Information System. Based on testing cluster counts from 2 to 10, the optimal number of clusters was found to be three, with a Davies Bouldin Index value of 0.605. This study is expected to provide benefits for the Jember Regency Central Bureau of Statistics, the community, and farmers in storing, managing, and disseminating information regarding rice crops in Jember Regency.
