Urban Heat Island (UHI) adalah sebuah fenomena lingkungan di mana suhu (misalnya bangunan, beton, aspal dan aktivitas industri) di daerah perkotaan secara signifikan lebih tinggi daripada di daerah pedesaan di dekatnya. Banyak bukti telah membuktikan bahwa itu dapat menyebabkan beberapa efek buruk bagi masyarakat, seperti peningkatan konsumsi energi. Suhu permukaan tanah (LST) diambil dari tiga perekaman data Landsat multitemporal untuk menganalisis pola spasial termal dan intensitas permukaan. UHI tidak dapat diketahui hanya melalui pemrosesan citra tanpa mengidentifikasinya dan analisa spasial melalui Sistem Informasi Geografis (SIG), proses penelitian ini ditandai dengan mengkonversi digital number pada citra satelit Landsat 7ETM+ dan Landsat 8 OLI/TIRS pada Band Thermal untuk menghasilkan LST, proses selanjutnya dilakukan di lingkungan perangkat lunak SIG untuk memperoleh sebaran UHI. Hasil analisa sebaran suhu permukaan daratan (LST) menunjukkan bahwa suhu maksimum kota padang tahun 2007 hingga 2013, terjadi kenaikan nilai suhu maksimum daratan kota padang sebesar 3.840C. Sedangkan untuk tahun 2013 hingga 2017 terjadi kenaikan suhu permukaan daratan 1.570C. Sementara itu untuk sebaran UHI kota padang pada periode pengamatan mengalami peningkatan yang signifikan, terdistribusi hampir keseluruh wilayah pinggiran kota dengan luas awal tahun 2007 yakni 31, 37 Ha menjadi 8.754,60 Ha pada tahun 2017.Kata kunci: Landsat, LST, UHI

The movement of the Sumatran fault is triggered by plate activity in the western subduction zone of Sumatra, namely the Indo-Australian plate which moves down the Eurasian plate, causing pressure to push the Sumatra region towards the north. The purpose of this study is for the results of Ascending and Descending data on the impact of faults that occur on the Semangko Segment Sianok fault from 2020-2023 and to map the Land Displacement of the Semangko Segment Sianok fault from 2020-2023. Based on the results of data processing in this study, it can be concluded that in this study using ascending and descending direction data that experienced land movement (Land Displacement) due to this movement the impact of faults that occurred due to seismic activity along the segment resulted in the impact of natural disasters such as landslides, and earthquakes. This impact was triggered due to land movement because the effects of surface faults and ground shaking did cause most of the damage in several events. The ascending data explains the annual uplift of 15.28 mm marked in dark blue and the red color on the map shows the subsidence of -30.55 mm per year, while the light bitu color dominates in urban areas or areas inhabited by many people. While in the descending data, changes in land movement show an annual uplift of 6.74 mm and the red color shows subsidence of -13.47 mm per year. From the color change of each data shows ascending and descending data experiencing land subsidence uplift and subsidence.

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.

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.

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.
