Abstract

The emergence of smoke caused by forest and land fires has very specific characteristics because most of it is on peatlands. Efforts to prevent forest and land fires are essential considering the prevalence of forest and land fires in Kubu Raya Regency, West Kalimantan Province. Therefore, this study aims to analyze the spatial pattern of spatial modelling of forest and land fire hazard areas with the Hybrid Fire Index and determine the correlation between forest and land fire hazard areas and the function of forest areas in Kubu Raya Regency. The Hybrid Fire Index method is used to weight each variable used. There are two factors that affect forest and land fire hazard areas, namely topography and human activities. Based on the results of the raster overlay analysis with the Hybrid Fire Index weighting, it was found that Kubu Raya Regency is dominated by moderate-level forest and land fire hazard areas of 654,901.50 hectares or 76.55%. The results of spatial modelling of forest and land fire hazard areas have been validated with hotspots in 2021 using the AUC/ROC curve and the area under the ROC curve value is 0.862 which indicates that the score of this model is very good. The results of the nearest neighbor analysis show that the ratio value is more than 1, which means that the distribution of forest and high-level land and forest fire hazard areas has a spreading pattern throughout the district. The results of the chi-square statistical test of the hazard area with the forest and land area functions yielded a significant value of less than 0.05 with a contingency coefficient of 0.603, which means that there is a moderate correlation between forest and land fire hazard areas and the function of forest and land areas.
