Abstract

This study aims to identify the condition of drainage channels located along Jalan Pangeran Antasari in Samarinda City and to present the data interactively through a WebGIS platform. Drainage issues in this area often cause waterlogging and flooding during heavy rainfall. Therefore, accurate and accessible mapping of drainage conditions is crucial. The research method involved physical measurements of drainage dimensions, such as top width, bottom width, channel height, and concrete width. The collected data were processed using ArcGIS Pro software by digitizing the drainage paths in the form of polylines, which were then published through ArcGIS Online in a dashboard format. Field documentation was also supported by geo-tagged photos that were converted into coordinate points on the map. The findings of the study revealed that several drainage segments have inadequate dimensions to accommodate stormwater during heavy rain, indicating the need for improvement or normalization. The developed WebGIS successfully presents spatial and descriptive information about the drainage conditions in an interactive format, making it a valuable reference for technical evaluation and drainage management planning in the area

Abstract

The coastal area has dynamic characteristics that continuously change due to the influence of complex interactions between natural factors and human activities. These changes are triggered by pressures from natural phenomena (such as erosion and flooding) as well as human activities on land and at sea, such as the development of settlements and the conversion of forests into agricultural land or aquaculture. The impacts of these activities can disrupt the stability of coastal ecosystems. In the coastal area of Manggar Village, which is home to several tourist destinations, the presence of tourist attractions and the development of supporting tourism infrastructure have the potential to alter the structure of the coastline. This activity necessitates research to conduct periodic monitoring in the form of determining the coastline affected by the extent of erosion and accretion from 2016 to 2024 every two years. The objective of this research is to present biannual data related to the dynamics of coastline changes and to measure the area affected by erosion (degradation) and accretion (sedimentation addition) in the coastal area of Manggar Village during the period of 2016-2024. The method used leverages remote sensing technology through Sentinel-2 image analysis with the NDWI (Normalized Difference Water Index) algorithm and land-sea segmentation techniques to accurately separate water and land areas. The results of this research are expected to serve as a scientific reference for sustainable coastal area management. This study shows results indicating that the coastline length in 2016 was 6,222 m or 6.2 km, and in 2024 it was 6,130 m or 6.1 km. The erosion from 2016 to 2024 covered an area of 115,770 m², while the accretion covered an area of 14,600 m². The findings of this research provide a clear picture
