Abstract

This study aims to analyze the geomorphological characteristics of the Hulonthalangi area and the Tanjung Keramat Coast in Gorontalo City, which serve as part of the supporting region of the Gorontalo Geopark. The study encompasses variations in topography, slope gradients, river flow patterns and stages, as well as the classification of geomorphological units. In general, the study area is classified into four main morphometric types: Lowland, Inland Lowland, Low Hills, and Hills. Slope analysis indicates variations ranging from flat to steep zones, reflecting differences in slope stability and highlighting areas with high erosion potential. Analysis of river flow patterns shows a dominance of parallel patterns, with valleys shaped like a “V” in the youthful stage and a “U” in the mature stage. Geomorphological characteristics were identified through remote sensing analysis using SRTM DEM data processed with ArcGIS software, and subsequently verified through direct field observations for geomorphological mapping and lithological distribution. This procedure was carried out according to scientific standards to integrate image analysis results with field data. The geomorphological units identified in the study area include Intrusive Hills, Volcanic Hills, Denudational Hills, and Alluvial Plains. Each unit possesses distinctive lithological and topographical characteristics that influence land-use patterns and environmental stability. This study provides significant contributions by supplying geomorphological data that can serve as a reference for planning, development, and sustainable environmental management in the Tanjung Keramat coastal area. The results also support efforts to mitigate potential environmental risks and promote wiser land-use practices in the Hulonthalangi area and Tanjung Keramat Coast.

Abstract

This study aims to analyze the geomorphological conditions of Bajo Village and its surroundings, Tilamuta District, Boalemo Regency. The methods used include slope analysis, river flow patterns, and geomorphological units. The data employed consist of topographic maps, satellite images, and the National Digital Elevation Model (DEMNAS), processed using ArcGIS software. Slope analysis was conducted to determine the steepness of the land, while river flow patterns were classified according to Howard (1967). Determination of geomorphological units was carried out through the interpretation of morphology and lithology, referring to Van Zuidam (1983). The results show four geomorphological units, namely fluvial lowlands, marine lowlands, low structural hills, and inland volcanic lowlands. The study area has slopes ranging from flat to steep, with rectangular river flow patterns dominant in the northeastern part. Overall, the geomorphological conditions of this area are influenced by lithology, geological structures, and fluvial processes that actively shape the local morphology.

Abstract

This study aims to describe and interpret the geomorphological characteristics of the Tapadaa region and its surroundings in Boalemo Regency, Gorontalo Province. The research focuses on identifying landforms, slope gradients, river flow patterns, and geomorphological units that develop within the study area. The methods used include analysis of the National Digital Elevation Model (DEMNAS) data, interpretation of topographic maps, and field verification. The results show that the area is divided into four main geomorphological units, namely marine plains, fluvial plains, volcanic hills, and denudational hills. The volcanic and denudational hills are characterized by steep slopes and structural control of trellis and rectangular drainage patterns, while the fluvial and marine plains are dominated by flat to gently sloping morphologies resulting from sediment deposition. Overall, the geomorphological condition of the Tapadaa region reflects a dynamic balance between endogenic and exogenic processes that shape the coastal and upland landscape of Boalemo Regency. The results of this study provide a basis for assessing geomorphological hazards such as erosion, flooding, and slope stability, and support sustainable coastal management in Boalemo Regency.

Abstract

The Bolihutuo area and its surroundings, in the Botumoito District, have geomorphological characteristics that are interesting for research, as they feature complex geomorphological conditions influenced by volcanic activity, fluvial processes, and structural factors. This study aims to map and classify the geomorphological units in the research area. The methods applied include spatial analysis and field observation. The results of this study indicate that the area has four main geomorphological units: structural hill units, volcanic hill units, fluvial plain units, and marine plain units. The morphography of the research area consists of lowlands and low hills with elevations ranging from 0 to 187.5 meters above sea level. Slope gradients vary from flat to very steep, while the river flow patterns are sub-parallel with young and mature river stages.The lithology consists of gabbro, andesite, granodiorite, granite, dacite, and alluvial deposits, and the land can be utilized for settlements, agriculture, and infrastructure development, adjusted according to its slope.
