“…Unfortunately, research on flood disasters in this province is still very limited. Some of the studies that have been done such as [6] about Flood Disposal Analysis of The Uru Ino River, East Halmahera Regency Using Synthetic Unit Hydrograph Approach (HSS) Gamma I And HSS Nakayasu; [7] about Flood Vulnerability Analysis in The Mede Watershed Region, North Halmahera Regency; [8] about Normalization of The Aru River to Complete Flood In Galela District, North Halmahera Regency; [9] about Use Of Hec-HMS To Delineate River Watershed Causes Flooding In The Kelurahan Rua Sub-District Of Ternate Island City Of Ternate; and [10] about Evaluation of The Tugurara River's Cross-Crossing Capacity For Flood Disposal In The City Of Ternate. most of the research was conducted in relation to flood disasters in urban districts in North Maluku, however, the Kobe-river in Central Halmahera district of this type of research is still lacking.…”

The objectives of this study are to mapping the hazard-prone area and to analyse the flood vulnerability index in Kobe Watershed, Central Halmahera District. In order to determine the optimal selection of weights for the factors that contribute to flood risk, GIS and multi-criteria decision analysis (MCDA) were used in conjunction with the application of the analytical hierarchy process (AHP) method to create the flood hazard map. The flood hazard map was generated by using selected hazard factors including land use, topography, slope, and rainfall pattern. The result shows that the Kobe River basin is a flood-prone area, with 77.46 percent of its land classified as less prone to flooding and 21.41 percent classified as flood-prone. However, only 21.41 percent of its land is classified as flood-prone. Only 1.13 percent of the land is protected from the danger of floods, compared to the whole country. The altitude factor is the most important element influencing flood susceptibility in Weda District, where the majority of the land (16.34 percent) is located at or below sea level, making it particularly vulnerable to flooding.
