Cocoa Land Mapping Based on Geographic Information System in East Kalimantan Using Leaflet JS and GeoJSON

East Kalimantan Province holds significant potential in developing cocoa commodities, a key sector in regional plantation development. However, there is a lack of an effective, web-based information system to visualize and manage data related to cocoa land distribution. This limitation hampers access for both the public and policymakers. To address this issue, a web-based Geographic Information System (GIS) application was developed using Leaflet JS and GeoJSON. This application aims to provide an interactive map that can display the location of cocoa plantations in the distribution of East Kalimantan Province, especially in Kutai Kartanegara, East Kutai, West Kutai, Mahakam Ulu, Penajam Paser Utara, Paser, Berau, Samarinda, Balikpapan, and Bontang, as well as providing information about the land area and cocoa production. Spatial data and cocoa production data are integrated into this application so that users, including farmers, entrepreneurs, and governments, can obtain comprehensive information about cocoa commodities in the East Kalimantan Province. By visualizing cocoa land distribution, the GIS tool is expected to support informed policymaking aimed at improving productivity and land use efficiency. It also serves to raise public awareness of cocoa potential in local communities.
