Abstract

Urban growth, both physical and non-physical, continues to increase, particularly in non-agricultural sectors such as settlements. Between 2000 and 2020, Jambi City experienced rapid and dense urban growth (Nugroho et al., 2022). Development must be carried out in accordance with the Regional Spatial Plan (RTRW) as stipulated in the Spatial Planning Law. This study aims to evaluate the current land use in Jambi City in 2024 to determine whether it aligns with the Jambi City RTRW for the period of 2013-2033. The method used in this research is overlay analysis, which involves combining attributes from the land use map and the spatial planning map of the RTRW. The results indicate that land use in Jambi City is predominantly residential (6,144.76 ha), followed by fields/cultivated land (5,468.64 ha), and shrubland (1,455.97 ha). The spatial utilization compatibility rate reaches 89.11%, demonstrating that the land use in Jambi City is in accordance with the established RTRW.

Abstract

The majority of Indonesians work as farmers, and oil palm plantations have become one of the key pillars in Indonesia's economy. This commodity contributes significantly to the country's foreign exchange, employment opportunities, and economic growth across various regions, particularly in Sumatra. Dharmasraya Regency, located in West Sumatra, is one of the areas with a substantial area of oil palm plantations. Therefore, it is essential to conduct a detailed land suitability mapping to ensure that the development is carried out sustainably and does not harm the environment. In this study, the overlay method was applied, considering several parameters such as slope, surface temperature, rainfall, soil texture, and elevation. The results of this study produced a land suitability map for oil palm plantations, which indicates the suitability levels of the land. (S1) Highly Suitable with an area of 57,107.17 ha, (S2) Suitable with an area of 53,217.43 ha, (S3) Less Suitable with an area of 167,281.13 ha, and (N) Not Suitable with an area of 25,211.35 ha.

Abstract

Land capability encompasses soil characteristics, topography, drainage, and environmental factors that support activities in a given area. Improper land use without conservation efforts can accelerate erosion and reduce productivity. Padang City is classified as a disaster-prone area due to its coastal location, low-lying land, high rainfall, and numerous rivers. Population growth increases the demand for built-up areas and water absorption land. This study analyzes land capability classifications in Padang City using a Geographic Information System (GIS) with a descriptive quantitative approach. The results indicate four land capability categories: very high, relatively high, moderate, and low. The majority of the area (45.88% or 31,843.30 ha) falls into the moderate category, allowing development with proper management. Areas with very high (22.79% or 15,816.54 ha) and relatively high (19.32% or 13,409.84 ha) capability are generally found in stable lowland areas, making them suitable for urban activities. Meanwhile, low-capability areas (12% or 8,328.52 ha) are located in steep hilly regions that require special management attention.

Abstract

Urban Heat Island (UHI) is a climatological phenomenon where urban areas exhibit higher temperatures than their surrounding region due to land use changes and increased built-up areas. Medan, as the third-largest metropolitan city in Indonesia, has experienced rapid population growth, leading to land-use changes and rising surface temperatures. This study aims to map the spatial distribution of UHI in Medan based on Land Surface Temperature (LST) using the Mono Window algorithm on Landsat imagery through Google Earth Engine (GEE) from 2014 to 2023. The results indicate a significant increase in UHI intensity, particularly in highly urbanized areas. Although UHI intensity temporarily decreased in 2017 due to the La Niña phenomenon and haze from forest fires in Sumatra, the overall intensity continued to rise, especially after 2020. In terms of spatial coverage, the Non-UHI area decreased by 630.13 ha, while low, medium, and high-intensity UHI areas increased by 167.41 ha, 437.23 ha, and 26.46 ha, respectively.

Abstract

Transportation infrastructure is essential for economic development and social activities. In areas like the Koto Tangah Batu Hampa–Barulak road in Akabiluru District, severe road damage hampers accessibility. Traditional manual inspections for assessing pavement damage are time-consuming and inefficient. This study utilizes Unmanned Aerial Vehicles (UAVs) to observe the distribution and classification of road surface damage through aerial imagery.A descriptive quantitative method was applied by comparing direct field measurements with UAV-captured photos. The process included aerial image acquisition, field validation, and spatial analysis using on-screen digitization. The study identified 55 damage points along a 350-meter road segment, with a total road surface of 2,087.61 m² and damaged area of 578.94 m². Four types of damage were detected: Edge Cracks, Potholes, Alligator Cracks, and Patches. The results confirm that UAV-based photogrammetry offers a fast, accurate, and efficient approach to monitoring road conditions. This method provides valuable data for infrastructure planning and maintenance, especially in remote or large-scale areas.

Abstract

Accurate elevation determination is one of the crucial aspects in oil and gas exploration activities, especially in the planning and management of well areas. This study aims to identify and compare the elevation of the Digital Terrain Model (DTM) obtained from aerial photography with terrestrial measurements, and to convert Digital Surface Model (DSM) data into DTM. The urgency of this study is driven by the need for accurate, efficient, and economical mapping methods, as well as validation of the methods used in topographic mapping. Digital Terrain Model (DTM) is a virtual model that adds elements such as fault lines and observations to correct artifacts from the original data, while DSM includes the height of all objects on the ground surface. The results showed that the largest elevation value in the aerial photo DTM was 14.416 meters at point L06 and the smallest elevation value was 6.567 meters at point A46, with an average elevation of 13.716 meters. Meanwhile, the comparison results of DTM elevation of aerial photography with terrestrial measurements showed the largest difference of 5.513 meters at point A46 and the smallest difference of -2.682 meters at point L21, with an average difference of 0.072 meters. The level of vertical accuracy (Z) based on the LE90 value is 0.2076 meters, which meets the geometric accuracy standard of 1:1000 class 1 scale according to BIG Regulation Number 15 of 2014. The results of this comparison are also supported by a 3D model of DTM elevation of aerial photography. This study provides an important contribution to the validation and improvement of the efficiency of topographic mapping methods based on aerial photography, as well as providing an overview of the accuracy of the data produced.
