Abstract

In searching for a track record of earth formation, people tend to interpret field data in a way that limits the potential of history and explanation, which is often less influenced by theory and available facts, this requires valid data gathered intellectually. Geocomputing, which is the digital processing of geographic data, is a relatively recent field that reflects a wide range of research methodologies and their application to help solve problems in machine learning, geostatistics, image processing, and spatial analysis, among other areas. The purpose of this study was to assess the effectiveness of using geocomputational methods with Avenza Map and ArcGIS. This study uses geocomputation and spatial analysis to carry out geological mapping at a scale of 1:25,000 located in the Battang area, West Wara District, Palopo City, South Sulawesi. Two aspects are the main focus in implementing this research method, namely when mapping by relying on Avenza with a base map sourced from the Rupa Bumi Indonesia (RBI) map and on data management using the ArcGIS application to become a 3D map. Lithological of the study area showed basalt, porphyry basalt, and phyllite. The geological structure that develops in the research area is joint and fault. Avenza Map work with spatial analysis in ArcGIS is obtained cognitively, involving the relationship between individual conditions, tools, and terrain conditions. It can be stated that the use of avenza on smartphones in this modernization condition is more effective. This research allows for a review of the practical level of use of computer methods ranging from mapping to data management. Regarding implementing cognitive mapping, Avenza Map and ArcGIS can be recommended tools in geo-computation techniques as more effective support for recording and managing data while still paying attention to noise that may occur as a barrier to data accuracy.

Abstract

Pulau Sulawesi khususnya Sulawesi Selatan dibeberapa lokasi merupakan daerah yang rumit menentukan susunan batuannya terutama penyusunan urutan stratigrafinya, sehingga penelitian ini diharapkan dapat mengungkap sejarah panjang fenomena geologinya. Riset dilakukan di Wilayah Tondong Tallasa, Pangkajene, Sulawesi Selatan, letak geografis berada pada koordinat 119°40’00” – 119°4’30” BT (Bujur Timur) dan 4°45’00” – 4°47’00” LS (Lintang Selatan). Penelitian ini dimaksudkan untuk pemetaan singkapan olistostrom dipermukaan secara detail menggunakan skala 1:2.000. Tujuannya untuk mengetahui karakteristik olistolith dari olistostrome dan menentukan lingkungan tektoniknya, sehingga dapat diperoleh hasil kesimpulan yang baik. Metode penelitian yang digunakan terdiri atas pemetaan traversing dan labo analysis. Berdasarkan hasil analisis geokimia berupa analisis unsur utama menggunakan metode Flouresensi Sinar-X (XRF), maka diperoleh jenis olistolith olistostrome pada daerah penelitian yaitu batuan Granit dan batuan Granodiorit. Susunan batuan tektonik terbentuk pada lingkungan tektonik Continental arc (busur kontinen).

Abstract

Indonesia is a country that has many islands and is rich in tourist destinations such as natural tourism, history, religion, culture, and so on. This attracts foreign tourists to visit or travel to Indonesia. One of the leading destinations in South Sulawesi which attracts foreign and domestic tourists is the Rammang-Rammang Karst in Maros which is known as the largest karst in Indonesia and is also a Global Karst Geopark Area approved by UNESCO. Rammang-Rammang Karst is an area that has a unique panorama, namely the type of karst, namely, tower karst with the natural landscape shape (geomorphology) of the Maros-Pangkep Karst area. Increasing the capacity of the Salenrang Village community is urgently needed so that the dissemination of geology-based information is more optimal. Therefore, the Department of Geological Engineering, Faculty of Engineering, Hasanuddin University, in collaboration with the Salenrang Village Government, organized a Laboratory Based Education (LBE) Service to increase the capacity of the people of Salenrang Village, Maros Regency. The methods used in this LBE event are observation, socialization and presenting information on tourist destinations through pamphlets and brochures. The observation method is carried out with the aim of systematically obtaining data on objects that will be socialized at the LBE service location in detail. Socialization was carried out to the Salenrang Village community about the tourism potential and geological conditions of the Rammang – Rammang Karst by distributing brochures and pamphlets to the Salenrang Village community in the LBE event area. Based on the results of the questionnaire, around 63% of visitors understand geological information in the tourist area, making it a challenge to disseminate better information. Through this LBE event, the people of Salenrang Village have proven that scientific information related to geological characteristics is very helpful in managing the geoheritage of the Rammang Rammang Area so that the increase in visitors will increase.

Abstract

Bulukumba Regency experienced a geological disaster caused by land movement in the form of landslides and horizontal ground shifts on 24 May 2023. Damage to several government buildings and facilities occurred due to the geological disaster. The government of Bulukumba Regency is aware of the geological disaster that is signalled to continue. Therefore, the Labo-Based Education (LBE) service activity of the Faculty of Engineering was carried out in the Herlang sub-district, Bulukumba Regency. This LBE activity was carried out with the Department of Geological Engineering, Hasanuddin University, and the Government of Herlang District, Bulukumba Regency. This LBE service activity aims to increase the capacity of government and community to introduce geological natural disasters and mitigation efforts. The methods used are making socialisation documents and socialisation of geological disasters to the Herlang sub-district government. Assessment of programme achievement was conducted during the socialisation and by giving short questionnaires before and after the socialisation (post-test). Socialisation on geological hazard potential and mitigation was conducted with the sub-district government, community leaders, community organisations, and the general public, with 46 participants. Based on the questionnaire result, about 85% of the participants understood the geological information in the Herlang sub-district, Bulukumba Regency. The socialisation activity is expected to be sustainable in educating the community to achieve responsive and well-coordinated disaster mitigation.
