Abstract

Flood hazard modeling in watersheds is an important step in natural disaster risk mitigation, especially in vulnerable areas such as Ambon City. This research focused on the Wai Batu Gantung, Wai Batu Gajah, Wai Tomu, Wai Batu Merah, and Wai Ruhu watersheds, using JRC Global Surface Water Mapping Layers data, NASA SRTM Digital Elevation 30 m data, and USGS Landsat 8 Level 2, Collection 2, Tier 1 data analyzed on the Google Earth Engine (GEE) platform. Prediction of built-up land in flood-prone areas was conducted by utilizing flood history analysis, hydrological modeling, and flood zone mapping. The results show that flood hazard modeling provides a better understanding of flood risk, assists in the development of safer land use planning, and increases public awareness of flood risk in Ambon City. It is hoped that the results of this research can contribute to flood risk management and sustainable regional development in the future.

Abstract

Kupang City, as the capital of Nusa Tenggara Timur Province, faces significant challenges in land management and settlement development due to rapid population growth and urbanization. This study aims to analyze and evaluate land suitability for sustainable settlement development, considering relevant environmental factors. The method used is Spatial Multi-Criteria Analysis (SMCA), which integrates geospatial data from the Digital Elevation Model (DEM), including slope, road networks, rivers, economic activity centers, and coastlines. The analysis results indicate that out of the total area analyzed, 7,227.04 hectares have high suitability, 4,341.12 hectares have moderate suitability, and 3,967.85 hectares have low suitability. Areas with high suitability are generally located near roads, economic activity centers, have lower slope gradients, and are far from rivers and coastlines, making them ideal for infrastructure development. The discussion emphasizes the importance of spatial and participatory-based spatial planning, as well as the need for monitoring low-suitability areas to prevent disaster risks. In conclusion, this study provides policy recommendations for more sustainable settlement development in Kupang City, integrating land suitability analysis and involving the community in the planning process, thereby creating

Abstract

This study aims to analyze vegetation density in Ternate City, Indonesia, using the Modified Soil-Adjusted and Atmospherically Resistant Vegetation Index (MSARVI) algorithm and Sentinel-2A images processed through Google Earth Engine. The analysis results show that the vegetation density index values range from -0.54 to 1.16, with normalization resulting in four density classes: low, medium, dense, and very dense. Ternate Island sub-district had the largest area of very dense vegetation (4,133.12 hectares), while Ternate Tengah sub-district showed the lowest vegetation density, reflecting the significant impact of urbanization. This study revealed that despite anthropogenic pressures, Ternate Island remains an ecologically critical zone. These findings emphasize the importance of conservation efforts and afforestation initiatives to improve environmental resilience amidst the growing challenges of climate change and urban development.
