Abstract

The development of scientific subjects in geography at the secondary school level has an impact on knowledge about geology, including rocks and their formation processes, the origin of the earth, to how to plan urban planning in a geographic information system. Geography books generally refer to the international earth science curriculum, making it very difficult for high school students to understand it. The main problem revealed by teachers and students who are interested in OSN in the field of earth is that the material being contested is quite complex. The basic problems of geology, spatial planning and disaster become national and even global issues. Through the Community Service Program activities, the Faculty of Engineering in this case is represented by a team of lecturers from the Geological Engineering Study Program offering Student Centered Learning methods to facilitate understanding of the National Science Olympiad material in the field of Earth Sciences. Besides that, it can also motivate and competitiveness to take part in competitions, especially for students of SMA Negeri 8 Gowa. The purpose of community service activities is to: a) Provide basic geological knowledge as part of earth science; b) Providing knowledge of Indonesian geology; c) Provide material tested in the national earth science olympiad; d) Provide the practice of identifying minerals and rocks, geological structures, fossils, and topographic map readings.

Abstract

The need for building materials is increasingly felt and expanded in line with the development of cities and regions, on the other hand mining activities can affect and damage the environment, such as what happened in the Barru, Sabangnaeri and Bottolai Rivers, where the former mines were left without reclamation. Based on this, a team from the Department of Geological Engineering, Hasanuddin University Makassar conducted counseling on batugunung mining to stone mining entrepreneurs in the Kamara - Bottolai area, Barru district in the form of Tri Dharma Perguruan Tinggi. This activity is expected to contribute, especially to stone mining entrepreneurs, to increase income and environmental safety. From the results of the field survey, several alternative materials of higher quality than currently managed (ultramafic rocks) were obtained for the community, namely dacite, andesite - trachea, diorite and limestone, scattered in several places in Barru Regency. The objectives of this community service activity are to: a. provide knowledge of rock quality and alternative locations; b. Provide technical guidance and mining work safety; c. Provide an understanding of environmental issues and the impact of mining

Abstract

The development of a geopark in the region should be initiated by the determination of geoheritage collected from the geological diversity inventory. The geoheritage initiation and preparation should be involved the educational institutions, we have assisted stakeholders of Bone Regency through the university community services (PkM) program in the form of the socialization of geoheritage in order to prepare and proposed Bone Geopark of South Sulawesi. To get an initial baseline of the geoheritage potential of Bone Regency and to measure participants' abilities, it begins with an FGD and a pre-test assessment, the results of the first FGD and pre-test activities showed that in general stakeholders have limited knowledge of the preparing document, characterization, and inventory of geoheritage, and geoheritage assessment. We have mentored geoheritage characterization, geodiversity inventory, and geoheritage assessment as problem-solving, which were conducted through surveys, desk study, and geoheritage assessment value methods. At the end of the activity returned to conduct FGD and post-test with involved all of the stakeholders. The results of the socialization program show a significant increase in the understanding of participants, especially the PERWIRA La Patau's was an increase of 28.5% (from 31.5% to 70%). Whereas representatives of the government, education institutions, and other non-government organizations still have limited understanding, increasing by 19.5% (from 17.0% to 36.5%). We still further proposed socialization and mentoring to prepare and propose geoheritage in the future. The geodiversity and landscape characteristics of the Bone regency can be divided into three morphology domains, namely: 1) The western part is demonstrated by the morphology domain of the highland of the volcanic complex that consists of non-volcanic, caldera, tower karst landscape features, 2) The central part is demonstrated by morphology domain of the Walanae valley that consisting of Walanae Depression and Walanae fault escarpment landscape features, 3) The eastern part is demonstrated by morphology domain of the Walanae structural lineament, the Kalamiseng volcano, the Taccipi cone karst and coastal line of the Bone Gulf landscape features. The results of the geodiversity inventory and geoheritage assessment of Bone Regency generally have suggested high scientific and educational values, moderate tourism potential, and low degradation potential. We concluded that this area has geodiversity potential and deserves to be submitted its geoheritage to the government.

Abstract

North Galesong District, an area located in Takalar Regency, is a coastal area with abundant natural resources and significant economic potential. Coastal areas are areas where sea and land meet. Despite this, people living in the coastal areas of North Galesong sub-district still face economic challenges that need to be addressed. Therefore, it is important to empower coastal communities in North Galesong Sub-district so that they can improve their economy and achieve sustainable development. Empowerment is an effort to increase the capacity and independence of individuals or communities in meeting their own needs. The goal of this paper is to propose a coastal community empowerment model that can be implemented in North Galesong District. The research was conducted by combining a literature review of empowerment models that have been successfully implemented in other coastal areas and analyzing the local situation in North Galesong District. The results show that an empowerment model suitable for North Galesong Sub-district should consider local characteristics and existing economic potential.

Abstract

Mass movement is one of the major natural disasters that claim many lives and property. The Kelara watershed, which is the research area, often encounters land movements that often cause casualties. The problem of mass movement often occurs in the upstream - midstream part of the Kelara watershed with mountainous to hilly morphology with moderately steep to steeply sloping relief. The parameters used in this analysis are lithology, distance from faults, distance from rivers, distance from streets, land use, rainfall, soil type, slope, profile curvature, and slope aspect. The analysis was conducted by giving weights based on the comparison of soil movement events to the class of each parameter using the Weight of Evidence method. Based on the Weight of Evidence method, the mass movement vulnerability zone is divided into five zones, very low vulnerability zone occupies 7.75%, low vulnerability zone occupies 27.11%, medium vulnerability zone occupies 31.76%, high vulnerability zone occupies 21.72%, and very high vulnerability zone occupies 11.66% of the total study area. Based on validation using the AUC value, the Weight of Evidence Method has a value of 0.771 (Fairly Good Model).

Abstract

In laterite nickel exploration, PT.Vale Indonesia Tbk, initialy relied solely on drilling methods to define profile boundaries based on mineral content and rock characteristics, but discrepancies of around 2% between reserve estimates and actual mining outcomes led to the adoption of geophysical methods as a complementary approach in 2014. This study aims to determine the characteristics of laterite nickel profiles by correlating resistivity values with geochemical data. Using Datamine and Leapfrog software, a 3D model of laterite nickel profiles was generated, identifying limonite (0–10 m depth, 201–250 Ohm.m resistivity), saprolite (0–10 m depth, 101–200 Ohm.m resistivity), and bedrock (>10 m depth, 101 to >801 Ohm.m resistivity). Variations in resistivity are influenced by factors such as mineral content and morphology. The volume estimated from resistivity correlation and drillhole data is 1,625,300 m³ for limonite and 1,902,600 m³ for saprolite, compared to 1,523,100 m³ and 1,390,100 m³ based on drillhole-only data, showing discrepancies of 6% and 27%, respectively. This study provides a clearer understanding of geological modeling using drillhole and ERT data to support laterite nickel ore mining and correlation modeling.
