Abstract

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

Abstract

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.

Abstract

Aerial photo mapping requires Control Points (CP). The Indonesian National Standard 8202:2019 regulates the number of CPs needed. The smallest area regulated is less than 250 km². Projects with an area of less than 1 km² have the same number of CPs as those with an area of less than 250 km². This is neither effective nor efficient because the CP work depends on the number of workers and requires time based on access to the project site. This study aims to identify the minimum number of CPs and the appropriate distribution of CPs for aerial photo mapping at a scale of 1:2,500 class 1 that is effective and efficient in terms of time and cost. The study uses seven schemes. Schemes 1 and 7 use 4 Ground Control Points (GCP) and 5 Independent Control Points (ICP). Scheme 2 uses 5 GCPs and 4 ICPs. Schemes 3, 4, 5, and 6 use 3 GCPs and 6 ICPs. Each scheme will be evaluated based on CE90 and LE90 values. The maximum CE90 value is 0.75 m, and the LE90 value is 0.5 m. The effective and efficient scheme in terms of time and cost is determined by the number of GCPs used, as well as the CE90 and LE90 values. The results indicate that all schemes have CE90 and LE90 values below the maximum standard. Scheme 4 is identified as the most effective due to having the highest CE90 and LE90 values among the schemes, with CE90 at 0.028 m and LE90 at 0.448 m. Scheme 4 is also identified as the most efficient because it uses a minimal number of GCPs—only three—distributed diagonally from the Southeast to the Northwest in the project area.

Abstract

The development of spatial data utilization has increased dramatically in the past decade. This is related to the widespread use of Geographic Information Systems (GIS) and the advancement of technology in acquiring spatial data. High-tech tools like UAVs (Unmanned Aerial Vehicles) are increasingly integrated with Geographic Information Systems (GIS) and other surveying and mapping technologies, and are therefore used in various surveying, mapping, and spatial analysis projects. One of the advantages of UAVs is that the captured data can be processed through software, producing images with high spatial and temporal resolution. The use of this technology demonstrates that mapping can be performed using photographic data. The purpose of this research is to analyze and map the distribution of cultural tourism sites in detail using UAV and GIS in Nagari Tuo Pariangan, Tanah Datar Regency. Based on the results of the research, it can be concluded that data collection was carried out using a DJI Mavic Pro drone, capturing 228 aerial photos which were then exported into orthophotos. Orthophotos function as a reference for the distribution map of cultural tourism sites. In addition, a database was created, integrating spatial (geographic) and non-spatial (attribute) data, containing the necessary information for tourism objects, such as the owner's name, year of construction, function, and history of the object. There are 31 cultural tourism objects in Nagari Pariangan, Tanah Datar Regency, consisting of 8 Rumah Gadang (traditional houses), 11 Surau (small mosques), 3 hot spring pools, 3 stone inscriptions, 1 hot spring pool, 1 Tuo Pariangan Mosque, 1 river, 1 Tabuik Mosque, and 1 Saruang Hall. Most of these cultural tourism objects are well-maintained by their owners, while a small number are neglected due to a lack of adequate human resources.

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.
