Abstract

The Karang Mumus sub-watershed is located in an urban area, making it vulnerable to development pressures and land use changes. Morphometric analysis of the Karang Mumus sub-watershed plays a crucial role in understanding the physical characteristics of the area and their relationship to water resource management and flood disaster mitigation in Samarinda City and its surrounding regions. This study aims to examine the morphometric characteristics of the Karang Mumus sub-watershed through the processing of DEMNAS data using the HEC-HMS 4.10 application. The results show that the Karang Mumus sub-watershed is divided into 15 sub-sub-watersheds, with a total area of 318.98 km². The sub-sub-watershed with the longest river channel is sub-sub-watershed 1, with a channel length of 18.57 km, while the shortest is sub-sub-watershed 12, with a channel length of 1.05 km. The average slope/gradient of the main river channel in the Karang Mumus sub-watershed is 0.15 m/m. The drainage density index of the Karang Mumus sub-watershed falls into the medium classification (0.25–10 km/km²). In terms of shape, the Karang Mumus sub-watershed is classified as elongated, with a Roundness Coefficient (RC) of 0.03 km.

Abstract

The GNSS survey method is currently widely used for various purposes, both scientific and practical, due to its advantages in terms of accuracy, speed, simplicity, and lower cost. Today, a wide range of GNSS survey instruments are available for benchmark point observations. Therefore, it is necessary to obtain information regarding the accuracy that these different instruments can provide. This study compares the results of benchmark point observations using the same method, namely the static method, but with two different instruments: Spectra SP80 and Comnav T300. The aim of this research is to determine the accuracy level of benchmark observations using the Spectra SP80 and Comnav T300, processed with the Trimble Business Center application. The comparative analysis shows that the Spectra SP80, when processed using Trimble Business Center, produces a smaller average difference in X and Y coordinates compared to the Comnav T300. However, in the Z coordinate, the Comnav T300 shows a smaller average difference than the Spectra SP80. Data analysis from the processing summary images provides information on the precision levels of both instruments. At benchmark point BM 2, the Comnav T300 demonstrated superior horizontal and vertical precision compared to the Spectra SP80. Conversely, at benchmark point BM 5, the Spectra SP80 showed better horizontal and vertical precision than the Comnav T300.

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
