Abstract

Flooding is one of the recurring hydrometeorological disasters in Manado City, influenced by the interaction between environmental physical conditions and urban development. This study aims to map flood risk levels in Manado City using a Geographic Information System (GIS). The method employed is quantitative spatial analysis using a weighted overlay technique that integrates eight variables, namely rainfall, elevation, slope, soil type, proximity to drainage basins, land use, population density, and building density. The results show that high-risk areas cover 566.32 ha, or 3.49% of the city’s total area, with an estimated 126,780 exposed residents. High-risk areas are predominantly concentrated in Wenang, Singkil, Tuminting, and parts of Paal Dua Districts. These conditions are associated with high rainfall, low elevation, gentle slopes, proximity to the Tondano River Basin, a predominance of built-up areas, and high concentrations of population and buildings. The resulting flood risk map can serve as a basis for disaster mitigation, land-use control, and risk-based urban planning.

Abstract

Population growth and spatial planning dynamics in Manado City require the provision of inclusive and equitable social infrastructure, including mosque worship facilities. Given the demographic characteristics of Manado City, where Muslim communities are distributed across various areas alongside the expansion of residential settlements, the availability and spatial distribution of mosques need to be systematically mapped to prevent spatial inequity and ensure compliance with urban spatial planning standards. This study aims to identify the level of availability of mosque worship facilities in Manado City based on established demand standards and to analyze the spatial distribution pattern of mosque worship facilities in the city. This study employs a quantitative approach using Geographic Information System (GIS)-based spatial analysis. Data were collected through field observations to record the geographic coordinates and existing conditions of mosques, complemented by secondary data on population and administrative boundaries. The availability analysis was conducted descriptively and comparatively by comparing the Muslim population and the required number of facilities with the existing number of mosques. Subsequently, the spatial distribution pattern was analyzed using the Average Nearest Neighbor (ANN) method. The inventory results identified a total of 199 mosques in Manado City. The availability analysis revealed variations in facility conditions, ranging from surplus and adequate to deficit across the study area. Furthermore, the ANN analysis produced a Nearest Neighbor Ratio of 0.95, a Z-score of −1.30, and a p-value of 0.19, indicating that the spatial distribution pattern of mosques in Manado City is classified as random.
