Abstract

Remote Sensing is a way to provide information efficiently both in terms of cost and time. In addition, the use of remote sensing in mapping the burned area can be carried out on a large scale but with a fast time for the prevention of land fires. Monitoring of forest fires is carried out to see locations that often become fire hotspots every year and to prevent frequent land and forest fires.The method used in this study is to map the burned area using multi-temporal data using the Normalized burning Ratio and Normalized burning Ratio 2 indices from Sentinel-2 images in May and September 2019. The trend data can be used to evaluate the moratorium on forest business permits or a peatland. Sentinel 2 has a higher spatial resolution of 20 meters compared to other multispectral images that can be accessed easily and free of charge, so it is suitable to be applied in areas that are not too large and minimizes the value of estimation errors, using Sentinel 2 imagery which has 13 channels will Selected several channels that can be used for index transformation, namely the NBR (Normalized Burn Ratio) and NBR2 (Normalized Burn Ratio2) indexes, both indices utilize Near Infrared, SWIR1, and SWIR2 channels which can provide information about the area after land fires,The research results obtained that burned areas are often identified as barren land, such as peat canals or vacant land. This is because the spectral reflection characteristics of objects in burnt areas are the same as those in non-vegetated land areas when the NBR index is transformed using the NIR, SWIR1 and SWIR2 channels. Keywords: Forest and land fires, NBR Indices, Sentinel-2.

Abstract

The city of Banjarbaru has been designated as the capital of South Kalimantan Province, a status that has the potential to trigger changes in land cover as part of regional development. Therefore, a study of land cover changes supervised the classification approach. The remote sensing data used were Landsat images from 2015 and 2025, with classification classes applied to vegetation, bare land, built-up land, and water bodies. Accuracy testing was carried out using a confusion matrix, the result of which indicated that the accuracy value was within the range permitted (>75%) by the Indonesian National Institute of Aeronautics and Space, so the classification result was considered satisfactory for further analysis. The dynamics of land change in the city of Banjarbaru have been quite significant over the last 10 years. The changes are visible in built-up land, which has changed by around 307.81%, followed by a decrease in bare land area in 2025. These changes indicate that a significant amount of open land has been converted into built-up land. This phenomenon indicates the potential for classification bias. Areas with sparse vegetation or hardened soil, such as post-fire land, former mining sites, or dry rice fields, may be misclassified as built-up areas because their spectral characteristics resemble surfaces like concrete or asphalt. For example, dry rice fields during the dry season or after harvest often show high reflectance and a homogeneous texture, making them appear similar to open land. These conditions were further influenced by the El Niño event in 2015.

Abstract

Kegiatan pengabdian ini bertujuan untuk meningkatkan kapasitas perangkat kalurahan di Kapanewon Pandak, Kabupaten Bantul dalam memahami, mengelola, dan memanfaatkan data digital terkait Tanah Kalurahan dan Sultan Ground. Permasalahan utama yang dihadapi ialah data pertanahan yang masih berbentuk arsip manual, tidak terstandardisasi, serta belum terdigitalisasi sehingga menimbulkan potensi kesalahan administrasi, tumpang tindih pemanfaatan lahan, dan lemahnya pengawasan aset desa. Melalui pendekatan partisipatif, kegiatan ini dilaksanakan melalui identifikasi dokumen legal, survei lapangan, Focus Group Discussion (FGD), pengolahan data spasial, serta sosialisasi pemanfaatan peta digital. Hasil kegiatan berupa peta digital Tanah Kalurahan dan Sultan Ground untuk empat kalurahan, Gilangharjo, Wijirejo, Triharjo, dan Caturharjo, serta rekapitulasi persil yang lebih akurat dan mudah diverifikasi. Kegiatan ini juga meningkatkan pemahaman perangkat desa mengenai pembacaan peta digital, verifikasi batas, dan pemanfaatan teknologi GIS sebagai instrumen tata kelola aset. Secara keseluruhan, digitalisasi peta terbukti mendukung transparansi, akuntabilitas, serta efektivitas pengelolaan tanah kalurahan dan Sultan Ground secara berkelanjutan.
