Abstract

This study aims to map the conversion of agricultural land into built-up areas in Padang Panjang City during the period 2019 to 2025. The transformation of agricultural land into built-up areas is driven by urbanization, population growth, and infrastructure development. The research method employed is spatial analysis based on Geographic Information Systems (GIS) and remote sensing, utilizing Landsat 8 and 9 satellite imagery processed using the supervised classification method and overlay analysis. The results indicate a significant decrease in paddy fields from 817.156 ha in 2019 to 562.264 ha in 2025, while residential areas increased from 414.442 ha to 702.863 ha over the same period. Accuracy assessment using the Confusion Matrix method yielded an overall accuracy of 92% with a Kappa coefficient of 0.85, categorized as very good. The study concludes that there is a significant conversion of agricultural land into built-up areas, highlighting the need for land-use control policies to prevent negative impacts on food security and environmental sustainability.

Abstract

Sijunjung Regency is one of the regencies in West Sumatra Province which is located in an area prone to landslides, earthquakes, fires and floods. Floods and landslides often occur due to changing river flow patterns, erosion and sedimentation in the Batang Ombilin, Batang Sukam, and Batang Palangki rivers, as well as the geology of Sijunjung Regency which mostly consists of rocks. This study aims to map the spatial distribution of areas prone to floods and landslides in Sijunjung Regency based on Geographic Information Systems (GIS) using scoring and weighting methods as well as parameters that compose the vulnerability which are then overlay. The parameters used in the analysis include land use, slope gradient, land elevation, rainfall, soil type, rock type and river network. The data used comes from administrative maps, spatial data, and regional hydrological and climatological information. The research found that flood-prone areas in Sijunjung Regency are dominated by moderate areas 68%, high areas 9%, and low areas 23%. The verification rate was 75%.

Abstract

Mount Marapi is one of the active volcanoes in West Sumatra, which erupted on December 3, 2023, followed by heavy rainfall that triggered a cold lava flood. This event caused damage to land, infrastructure, and vegetation around Sungai Pua Subdistrict, Agam Regency. This study aims to analyze vegetation density changes before and after the lahar event and to map the affected areas using Sentinel-2 satellite imagery, applying the Normalized Difference Vegetation Index (NDVI) and spatial overlay methods. The results show a decrease in very dense vegetation from 623.127 ha (42.38%) to 199.095 ha (13.54%), and an increase in poor vegetation from 354.269 ha (24.09%) to 551.566 ha (37.50%). The total vegetation density change reached 734.03 ha out of 1,470.32 ha. Identification of affected areas also indicates that the lahar spread along river channels from the summit to the slopes, with an affected area of 110.832 ha. These areas include agricultural land, plantations, and settlements along the riverbanks that were damaged by volcanic materials.

Abstract

Tourism is a strategic sector in regional development. Agam Regency offers a variety of tourism potential, including natural, cultural, religious, and artificial attractions. However, information about these attractions is still fragmented and unintegrated. This study aims to identify the distribution of tourist attractions and design a WebGIS-based tourism information system. Primary data were collected through field observation and documentation, while secondary data were obtained from government agencies. Spatial data were processed using QGIS and ArcGIS, non-spatial data were stored in MySQL, and the system was developed using HTML, CSS, JavaScript, PHP, and XAMPP. The results indicate that the system successfully displays interactive maps, provides detailed descriptive information, and is compatible across devices. The user feedback has been positive, indicating high satisfaction with the system. This WebGIS-based system proves to be an effective tool for tourism promotion and management, helping Agam Regency integrate its tourism potential and make it more accessible to tourists and stakeholders alike.
