Abstract

In simple terms, geodiversity is defined as the diversity of non-living natural components in the form of lithology, minerals, fossils, structures and landforms in an area that forms the earth's surface which has differences, thus forming diversity. Geodiversity can be an important factor in developing the tourism industry and local community identity by conducting special research in the form of investigating geological heritage and cultural heritage and integrating the results for educational outcomes in education, promotion and tourism infrastructure. Gorontalo Province has many locations that show great geological diversity, but many of them have not been explored, studied, or not yet established for geotourism. The extraordinary geo-diversity together with the deep ecological resources and cultural heritage provides a valuable basis for the development of geotourism and geoparks. Geological research at Dulanga Beach has never been carried out to assess the existing geological features. Research on Dulanga Beach generally only focuses on the tourism promotion sector. The aim of this research is to determine the potential geodiversity potential of Dulanga Beach. The method used in this research is the main method, namely geological observation and geodiversity assessment methods. Based on research results, the Dulanga beach location has 3 geological features in the form of geomorphology, lithology and fossils or paleontology. The results of the geodiversity assessment show that the Dulanga Beach research for the Scientific Assessment aspect is in the Moderate class, the Educational Assessment is in the High class, the Tourism Assessment is in the Moderate class, and the Assessment Degradation (Degradation Value) is included in the High class.

Abstract

One of the natural resources commonly utilized as raw material in industries—particularly for piling foundations, construction base mixtures, and other basic building materials—is igneous rock. The quality of the rock used as a construction material plays a crucial role in determining its suitability for various infrastructure applications. Therefore, specific physical and mechanical properties of the rock must be evaluated to assess its feasibility for construction use (Yuwanto and Araujo, 2020). This study aims to analyze the characteristics and quality of the rock at the research site and assess its suitability based on the classification from the Indonesian Industrial Standard (SII) 0378-80. The methods used include the Geological Strength Index (GSI) and Unconfined Compressive Strength (UCS). Data were obtained from field observations using the scan line method and laboratory testing of rock mechanical properties. The GSI analysis shows that the rocks have Structure Condition Rating (SCR) values of 6, 10, and 7, indicating structural influence ranging from blocky/disturbed to disintegrated conditions. The UCS analysis results show compressive strength values ranging from 233.351 kg/cm² to 1.161 kg/cm². According to the SII 0378-80 classification, these values reflect the varying levels of suitability of the rock for construction purposes.
