Mineral exploration is one of the important activities to obtain location information about where the minerals are, but this exploration process takes years and costly especially when carried out over a wide area. Therefore through this study the application of Geographic Information Systems and Remote Sensing for mapping the distribution of potential mineral deposits of lateritic nickel (Ni) is tested. The method used is the analysis of digital data Landsat 7 ETM +. Rocessed image data by performing a technique sharpening contrast, filtering, creation of a composite image and image fusion. Image data processing is for the interpretation of visual straightness, limit unit morphology and the estimation of mineral lateritic nickel. The data as well as analysis techniques NDVI in order to obtain the pattern of vegetation density on the surface. The results showed that the presence of lateritic nickel mineral formed on ultramafic rocks undergoing the process of weathering and serpentinization. Characterized with the appearance of geological structures identified as robust and fault structures. Which are also represent on the remote sensing images as rectangular flow patterns.Ultramafic rocks are located in the morphological undulating hills. Vegetation is identified growing on ultramafic rocks are categorized as dense vegetation. Vegetation that grows in the form of a single tree with an average diameter ≤30 cm. result generating estimates of mineral potential areas of lateritic nickel has an area ranging 6.3 ha.

The fast growth of population, the increased flow of transportation, industry spread in Padang Municipality, and thermal inverse effect can trigger air pollution leading to acid rain in the municipality. The aims of this study are to analyze the nitrate, sulfur and pH contents of rain water and to analyze the effect of rain intensity, air temperature, air pressure, and wind direction and speed on the acidity of rain water in Padang Municipality. The study was conducted using a field measurement and a laboratory test. The sample of rain water was collected by a purposive sampling technique as displayed in Thiessen polygon. The sample of rain water was collected in ten times of sampling in six regions of Thiessen polygon in Padang Municipality. The data collected were analyzed by climate data analysis, rain intensity analysis, multiple linier regression analysis, spatial analysis, and descriptive analysis. The results of the laboratory test showed that sulphate and nitrate contents in rain water in Padang Municipality was still under the threshold of clean water quality No. 416/MENKES/PER/IX/1990, i.e. 400 mg/l for sulphate and 10 mg/l for nitrate. The effect of rain intensity on the acidity of rain water was inversely proportional to sulphate and nitrate contents and directly proportional to pH. The results of validation test and multiple linear regression analysis about the effect of sulphate, nitrate, and pH contents and independent variable as the selected factor displayed in classic assumption test showed that sulphate and pH contents had a significant effect, while nitrate content had no significant effect

This research aims to improve the skills of GNSS usage by students in Geomatics Engineering Department of SMKN 1 Bukittinggi. Training on the use of GNSS will be conducted using the latest GNSS device owned by the school. The students will be taught about the operation and programming of GNSS devices, as well as methods of analyzing the data generated. After the training, the students will be evaluated through tests and field projects. The results show that most students initially have a limited understanding of GNSS and difficulty in using GNSS devices. The improvement of this ability has positive implications for the preparation of students in facing the increasingly complex demands of the job market. The ability to use GNSS is becoming more important in various fields such as construction, mapping, surveying, precision agriculture, and environmental monitoring. Students who have been well trained in the use of GNSS will have a competitive advantage in seeking employment or pursuing further education.

This study aims to identify and analyze the impact of the Galodo disaster in Sungai Jambu (Pariangan, Tanah Datar, West Sumatra) using PlanetScope satellite imagery. Galodo disasters, which are flash floods that transport materials such as soil and rocks, often occur in mountainous areas and cause significant damage to the environment and infrastructure. Located on the slopes of Mount Marapi, Sungai Jambu is one of the areas prone to galodo due to its geomorphology and high rainfall. The research methodology involved using PlanetScope images before and after the Galodo accident on May 13, 2024. Data processing included radiometric and geometric correction as well as image composite analysis to detect changes in land cover and river flow. The 3-2-1 and 4-3-2 composite images were used to detect changes in vegetation, stream conditions and degraded open land. The results showed significant changes in land cover and river flow due to the Galodo disaster, characterized by increased water turbidity and damaged vegetation. This study confirms the effectiveness of PlanetScope images in monitoring and identifying the impacts of the Galodo disaster. These findings provide important information for post-disaster mitigation and recovery planning and help identify areas that require restoration. Thus, the use of PlanetScope images can improve our understanding of environmental damage caused by disasters and support more effective and sustainable mitigation measures

The beach is a form of geology composed of sand located in coastal areas and the position of the coastline is dynamic. Identification of shoreline changes is important information that can be obtained from Remote Sensing Data and Geographic Information Systems (GIS) which has advantages and speed in the results of the process. This research was carried out in the Pasir Baru Beach area, Nagari Pilubang, Sungai Limau District using Landsat 8 OLI Satellite Images in 2014, 2018, and 2022 with the aim of determining changes in coastlines in the 2014-2018 and 2018-2022 ranges and knowing the extent of coastline changes in the 2014-2018 and 2018-2022 ranges. The method used to extract the coastline is obtained from the extraction results from the Landsat 8 OLI Satellite Image using the BILKO algorithm method, for the calculation of distance and rate of change of coastlines using a digital coastline analysis system (DSAS) with two statistical methods, namely Net Shoreline Movement (NSM) and End Point Rate (EPR) and for calculating the area of coastline change using the Calculate Geometry menu using attribute information in the software ArcGIS 10.5 in square meters (m2). Based on the results of the study that the coastal process that occurred in the research area from 2014-2022 was an erosion or abrasion event. The amount of erosion increased from 2018 to 2022 with an average erosion rate of 2.11 m / year, while the average abrasion distance was 7.49 m / year which was characterized by the formation of abrasion gawir and the fall of new trunk trees around the beach due to soil erosion. Meanwhile, the average rate for sedimentation or accretion events in 2018-2022 is 0.04 m/year while the average distance of change due to accretion events is 0.15 m/year. With a total area of erosion or abrasion events in 2018-2022 of 48,220.4 m, with an average annual area change of 12,055 m. Meanwhile, the total area of sedimentation or accretion events in 2018-2022 amounted to 449.3 m with an average annual area change of 112.3 m.
