Abstract

The southern coast of Gorontalo has complex geological conditions. This is indicated by the strong tectonic influence with the uplift of the Quaternary limestone at high elevations. The distribution of this limestone is very unique because it is located between the dominance of volcanic and plutonic rocks that form the northern arm of Sulawesi. The purpose of this study was to focus on the characteristics of limestone on the south coast of Gorontalo based on specific gravity and water absorption tests. The research methods used to achieve these objectives consist of field geological surveys and laboratory analysis of the specific gravity and water absorption tests of coarse aggregate. The field geological survey consisted of taking limestone samples for laboratory analysis and petrological analysis. The results showed that the limestone on the southern coast of Gorontalo is dominated by the coralline floatstone facies. Characteristics of the coralline floatstone facies based on laboratory analysis showed an average specific gravity of 1.74 and an apparent specific gravity of 2.04. While the average percentage of limestone water absorption is 8.41%.

Abstract

Education is the pillar and foundation of nation building and in the digital era that must develop rapidly, technology integration is a must. In an era filled with advanes in digital technology, new challenges have emerged in the world of education, especially in building professionalism for educators. This research aims to identify challenges and transformation efforts in building the professionalism of geography teachers in the digital era in the five best schools in Gorontalo City. This study uses a qualitative approach with an in-depth interview method with 10 geography teachers from each school. Data will be collected through learning observations, interviews with geography teachers, and document analysis. Teaching patterns, important findings, and emerging trends in the digital era related to challenges and changes in building the professionalism of geography teachers in the digital era will be analyzed thematically.  The results show that despite significant challenges, such as limited technological infrastructure and resistance to change, teachers are actively trying to integrate digital technology in learning. This transformation is seen in the use of Geographic Information Systems (GIS) and digital project-based learning that have improved student engagement and learning effectiveness. These findings highlight the importance of institutional support and continuous professional development to strengthen teacher professionalism in the digital era.
