Taman Lenteng Agung is located in Lenteng Agung Village, Jagakarsa District, South Jakarta, DKI Jakarta. The park, which has an area of 14,000 m2, is a riparian zone. The riparian zone is a transitional space between rivers and land, which in the zone serves as a buffer from land. Several points in the Pingkal Park area are landslide-prone areas. One of the causes of intense soil movement on sloping land is a land management system that is not based on soil conservation principles. Perennials that can accommodate the soil are very limited in population on the slopes due to massive development. This community service activity aims to convey information about the function, benefits of riparian zones, erosion potential, and soil movement that can occur in Taman Pingkal. The method used in the implementation of this activity is in the form of socialization through booklet media. Participants were collected in the park and then given material through socialization by distributing booklets to activity participants. The socialization participants amounted to 15 people from the community and park managers who used the park for sports activities and recreational activities. The result obtained from this activity is that the manager and the community still do not know the functions and benefits of riparian zones, with this activity the community becomes aware of the functions and benefits of the park and has the desire to keep the park from being damaged. The use of booklet media can be an alternative for the community to obtain information about the functions and benefits of the park. Based on the results obtained from socialization activities, the dissemination of information to the community around the park needs to be expanded. The community needs to be involved in the management of the park as an open space. In addition, the attention of the local government to the sustainability and comfort of the park as an open space for the community is expected to be increased.

The occurrence of landslides in Indonesia has been consistently increasing over the years, particularly in mountainous regions during the rainy season. The country's tectonic conditions, easily brittle volcanic rocks, and wet tropical climate contribute to the heightened potential for landslide disasters. The combination of anthropogenic and natural factors, leading to changes in land use, further exacerbates the risk of landslides, resulting in loss of life and property. This research focuses on the Purabaya Subdistrict, Sukabumi Regency, with the aim of analyzing landslide vulnerability. The analysis results in the creation of a Landslide Vulnerability Map for Purabaya Subdistrict, utilizing a scoring method overlaying rainfall maps, rock type maps, slope inclination maps, land use maps, and soil type maps. A total of 156 land units are identified with classifications of low, moderate, high, and very high landslide vulnerability. Areas with high and very high vulnerability levels encompass 49.52% of the total area, while low vulnerability areas constitute only 6.19%. Purabaya Subdistrict stands out with a dominant high vulnerability level, contributing 49.52% to the total area, whereas low vulnerability areas only cover 6.19%. These findings provide a foundation for landslide disaster risk management in the region.

Bandung Regency experiences significant dynamics of surface temperature change due to rapid development and land use change. This study aims to analyze the dynamics of Land Surface Temperature (LST) in Bandung Regency during the 2018-2022 period and identify the factors that influence it. The method used is the analysis of Modis Terra Land Surface Temperature and Emissivity 8-Day Global satellite image data using Google Earth Engine to produce average surface temperature distribution data presented in the form of graphs and temporal maps. The results showed surface temperature variations ranging from 18°C to 32°C, with distribution patterns influenced by topography and land cover. The mountain-dominated southern region has temperatures of 18-20°C, while the northern and northeastern regions reach 28-32°C. There is a seasonal pattern where the September-October period shows the highest temperatures, while June-July is relatively stable. Land conversion, which accounts for 34,327.48 hectares (49.25%) of total land change in the BMA, contributes significantly to surface temperature dynamics. It can be concluded that land cover change, infrastructure development activities, and topographic factors have a major influence on surface temperature variability in Bandung Regency, so that stricter spatial management and integrated afforestation programs are needed to mitigate the impact of increasing surface temperatures.
