The increase in population and urban development leads to higher energy consumption, which adversely affects environmental quality. The resulting impacts include a reduction in green open spaces, an increase in air pollution, and a rise in surface temperatures. This leads to the phenomenon known as the Urban Heat Island (UHI), where urban areas experience higher temperatures than their rural surroundings. This research aims to identify the UHI in Padang City using Landsat multitemporal data over a 5-year observation period from 2019 to 2023. The method involves converting digital numbers from Landsat 8 OLI/TIRS and Landsat 9 satellite images in the Thermal Band to generate Land Surface Temperature (LST) data. Subsequent processing is carried out in GIS software, such as QGIS or ArcGIS, to obtain the distribution of UHI. The research findings indicate fluctuations in land surface temperatures, with both increases and decreases observed over the study period. Each year witnesses an expansion of the UHI area, indicating worsening heat conditions in various regions of Padang City. The findings suggest that land surface temperatures will continue to rise with further urban expansion, highlighting the need for proactive measures. Therefore, it is crucial to develop and implement policies to control and mitigate the negative impacts of UHI in urban spatial planning.

Land Surface Temperature (LST) is widely utilized in current studies, particularly as an initial survey tool to assess geothermal activity in locations suspected to have geothermal sources. The research method involves geometric correction of Sentinel-3 imagery and conversion of temperature units from Fahrenheit (F) to Celsius (C) to ensure accuracy in temperature measurement. Image data processing from Sentinel-3, including thermal band analysis, is carried out to generate land surface temperature values. The field-measured temperatures are then compared to the land surface temperature data obtained through processing. The temperatures in the location, ranging from 23°C to 35°C, fall within the minimum geothermal temperature range, indicating potential geothermal activity. However, the LST values from the image data exhibit some differences compared to the on-site measurements. These discrepancies are categorized into classes I (23.7 – 24°C), II (24 – 24.3°C), and III (24.3 – 24.8°C), marked by red areas in the LST values. These discrepancies are attributed to various factors during image recording and processing, such as atmospheric interference and sensor calibration.

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
