“…The land that converted land cover change to non-forest experienced increased fire activity. Based on study [8,9] also confirmed that non-forest land namely shrubs, reeds and dryland farming, are the main source of land fires in North Sumaetra region. A study by [10] found that land cover change after forest and land fires, where forest and shrub cover turned into plantations.…”

Gunung Leuser National Park (GLNP) is home to Indonesia’s native species, the Sumatran orangutan (Pongo abelii). The GLNP in some of its areas has experienced forest degradation, one of which is by land clearing activities by burning. The purpose of this study is to analyze land cover changes due to forest fires in the habitat of Sumatran orangutans in GLNP, Langkat Regency, North Sumatera Province. This study used temporal and spatial analysis of fire hotspot data with land cover. Temporal analysis of land cover changes was conducted between before and after forest and land fires in the study area. There are at least 6,783 ha of forest fires, of which 1,541 ha were habitat distribution areas for Sumatran orangutans. From 2000-2019, 158 hotspots were detected, of which 36 hotspots were in the distribution area of Sumatran orangutan habitat. Land cover in the study area has mostly changed from primary dryland forest to plantations. The primary dryland forest that remained in the study area only 483.51 Ha in 2019 after converting since 2000. Communities around GLNP need to be assisted in the process of ecosystem restoration through a conservation partnership pattern to restore the function of the area, one of which is as a habitat for Sumatran orangutans.

“…The land cover in the Dieng Kulon village was classified using the Geographical Information System (GIS) (Thoha and Triani 2021). The method starts with retrieving the Dieng Kulon boundary and Landsat 8 Operational Land Imager (OLI) images of this village with a spatial resolution of 30 m per pixel.…”

Abstract. Lestari F, Tua IN, Muzanni A, Nugroho DF, Wibowo AA, Wartono T, Widanarko B, Saepullah A, Modjo R, Farida M, Erwandi D, Aryani DD, Kadir A, Widiatmoko AI, Hendra, Herwanto ZJ, Tejamaya M, Hamid RA, Fatmah, Gunawan EL, Setyowati DL, Hafids MF. 2023. NDVI, suitability, and carrying capacity of Dieng Plateau Forests to sustain Dieng Kulon Village tourism. Biodiversitas 24: 282-289. Village tourism is a form of tourism that can support the conservation of an ecosystem. On the Dieng Plateau, Dieng Kulon is one of the tourism villages located in Banjarnegara district, Central Java, Indonesia. Despite the rapid growth of tourism in Dieng and its potential environmental consequences, information on tourism carrying capacity in Dieng is still limited. Here, this study aims to measure the suitability and carrying capacity of Dieng Kulon Village. The suitability for tourism is measured based on the Normalized Difference Vegetation Index (NDVI). Equation was used to calculate the carrying capacity. According to the findings, forest areas with a size of 23.9% and high NDVI values ranging from 0.87 to 0.91 were deemed very suitable for birdwatching and hiking activities. Agricultural land made up nearly half of the village (57.1%) with high NDVI values (ranging from 0.36-0.86) was deemed ideal for sightseeing activities. In comparison to other types of land, agricultural land had the highest carrying capacity, followed by forest land. Agricultural land can support 84.8-155.2 people per day for sightseeing activities. Forest areas are suitable for hiking and birdwatching activities. At least 51.6 to 334.9 people per day are allowed for hiking activities. Birdwatching in the forest is limited to 3.1-19.9 people per day. To conclude, carrying capacity information is very important for managing village tourism in a sustainable manner.

“…The data shows that almost all areas included in the Miu sub-watershed are on steep to very steep slopes. This is one of the factors causing the rapid flow of water into rivers which causes high flood intensity [21,22]. The scoring slope map can be seen in Figure 1 (a).…”

Frequent floods and droughts, which cause significant material and intangible losses, are a result of watershed destruction especially in Central Sulawesi. Flash floods have been a common occurrence in portions of Central Sulawesi in recent years, and Miu Sub-watershed is one of those watersheds. Both the material and non-material effects were fairly significant, especially for the local population. The biophysical conditions of the area must be known in order to identify flood target areas and flood causes. The application of Geographic Information Systems is the technique used to assess floods. This study’s objective is a spatial examination of the Miu sub-watershed flood susceptibility. Flood-prone areas are analyzed using a variety of techniques, including overlaying, categorization, scoring, weighting, and modeling. The three types of flood danger classes are non-prone, medium, and prone. The Miu sub-watershed region has an area with a flood hazard class for the non-prone category of 64,255.173 ha, a medium category of 57,909.003 ha, and a vulnerable category of 4,838.917 ha. Bangga Village in Dolo Selatan Sub-district, Tuva Village in Gumbasa Sub-district, and Bolapapu Village in Kulawi Sub-district are the Miu Das regions with the widest category of high flood threat.
