Abstract

Gorontalo Province has areas that are prone to landslides, especially in North Gorontalo Regency. This study has two main objectives, namely identifying the lithology that makes up the research area and analyzing the level of landslide vulnerability in area. This study uses the Multi Criteria Evaluation (MCE) method with the use of GIS analysis to achieve its objectives. Determination of the level of landslide vulnerability is carried out by overlaying parameters such as lithology, straightness density, slope gradient, soil type, rainfall and land use. The lithology that makes up the research area consists of andesite, agglomerate, sandstone and alluvial deposit units. Based on the results of the analysis, landslide vulnerability in the research area can be categorized into 3 classes, namely. Low landslide susceptibility class (34.13 km2), medium landslide susceptibility class (66.89 km2) and high landslide susceptibility class (19.65 km2)

Abstract

The research is located in Gorontalo Province located between 0°48'0”- 0°58'0” N and 122°36'0” - 122°44'0” E. The location of this research is in Monano District, North Gorontalo Regency, Gorontalo Province. This geological mapping aims to map the geological conditions of the research area. The methods used are field surveys and spatial data analysis. Based on geomorphological data, 4 units were obtained in the form of Volcanic Hills Units, Denudational Hills Units, Marine Plains Units, Fluvial Plains Units. On the geological map, the lithology of the research area consists of andesite, agglomerate, sandstone alluvial sediment units. The results of the lineament density consist of 3 density classes, namely low, medium and high.
