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

Administratively, the study area is located in Wolo District, Kolaka Regency, Southeast Sulawesi Province. This research aims to assess the relationship between the serpentinization process and the grades and distribution of laterite nickel. The methods employed include data collection through drilling, which involves logging procedures and laboratory analyses such as petrographic and geochemical analyses (X-Ray Fluorescence). The geocomputational method, Inverse Distance Weighting (IDW), is subsequently applied to determine the distribution of laterite nickel. Observations indicate that the bedrock in the study area consists of ultramafic rock types, including Lherzolite, Olivine Websterite, and Serpentinite. Some of these rocks have undergone serpentinization, while others have not. The serpentinization levels in the study area are classified into three categories: weak serpentinization (≤15%), moderate serpentinization (35%-50%), and strong serpentinization (55%-75%). Nickel grades in strongly serpentinized rocks are 0.22%, in moderately serpentinized rocks 0.50%, in weakly serpentinized rocks 0.32%, and in rocks that have not undergone serpentinization 0.30%.

Abstract

The research area is administratively located within the PIT Z area of PT. Ceria Nugraha Indotama's mining permit (IUP) in Wolo District, Kolaka Regency, Southeast Sulawesi Province. This study examines the correlation between topographic features and laterite deposit characteristics in the study region. The research methodology incorporated fieldwork, data processing using ArcMap 10.8 and Surpac 6.3 software, and laboratory analyses including petrographic and geochemical examinations. Analysis revealed two primary topographic features in the research area: steep hills and undulating hills. Steep hill topography exhibited high concentrations of MgO compounds and relatively thin laterite deposits. Conversely, undulating hill topography demonstrated optimal laterite deposits characterized by thicker laterite horizons and elevated Fe and Ni content. The distribution pattern of laterite deposits throughout the study area indicates that slope gradient significantly influences water drainage, which serves as the principal medium for the lateritization process, thereby establishing a direct relationship between topographic features and laterite deposit profiles.
