One of the regions in Indonesia with a relatively high risk of landslides is West Bandung Regency, West Java Province. Given its active land use and dense population, this area becomes more vulnerable to the impacts of natural disasters. The objective of this research was to identify the elements and contributing causes of landslide vulnerability, especially for West Bandung Regency's tourism sector. The robust vulnerability scenarios were generated by using Spatial Multi-Criteria Evaluation (SMCE). Four scenarios of equal vulnerability, social vulnerability (SV), physical vulnerability (PV), and environmental vulnerability (EV) are produced using the SMCE technique. According to the scenario results, three districts, Rongga, Cipatat, and Parongpong, show dynamic vulnerability, whilst the remaining districts show consistent classes. The quantity of visitors and physical infrastructure, such as access to the road, are examples of social elements that significantly impact the degree of vulnerability. The study's findings led to the creation of three vulnerability classes in West Bandung Regency: low class, with values between 1.34 and 1.78, medium class, with values between 1.79 and 2.07; and high class, with values between 2.08 and 2.36. The photo-tagged map of road access and tourist destinations in West Bandung Regency provides in-depth insight into the factors that influence the vulnerability of tourist destinations, taking into account disaster risks due to geographical conditions, infrastructure readiness, and the effectiveness of mitigation efforts in balancing tourism development and environmental resilience.

Indonesia is located between four major tectonic plates, making it vulnerable to various natural disasters, including floods caused by high rainfall, river sedimentation, and land-use changes. Malang City, as a growing urban area, has experienced an increasing frequency of floods over the past five years. This study aims to evaluate the factors contributing to flood vulnerability and produce a risk zoning map using Geographic Information System (GIS) technology. A quantitative approach was employed by analyzing parameters such as rainfall, soil type, slope gradient, elevation, land use, and river proximity using the weighted overlay method. The results indicate that high-risk areas include the districts of Klojen, Blimbing, Sukun, and Lowokwaru. Key factors include high rainfall intensity, limited infiltration areas, and proximity to major rivers. This zoning map is expected to assist the government in disaster mitigation planning, improving drainage infrastructure, and enhancing community resilience to floods.

Malang City is one of the regions in Indonesia with significant flood risk due to a combination of natural factors and human activities. This study aims to map flood-prone areas using Geographic Information System (GIS) technology by considering six main parameters: slope, elevation, rainfall, soil type, land use, and river buffer. Using the weighted overlay method, the flood risk zoning map is classified into three categories: low, medium, and high. The results show that 67.22% of Malang City falls under the high-risk category, particularly in Klojen, Blimbing, Sukun, and Lowokwaru districts. Dominant factors contributing to flood vulnerability include high rainfall, dense settlements, and a lack of green spaces. The study recommends mitigation measures such as improving drainage systems, increasing green areas, and implementing risk-based spatial planning to minimize flood impacts. The flood risk zoning map serves as a crucial tool for the government to plan and manage floods more effectively.

Merapi Volcano is one of the most active volcanoes in Indonesia, which poses a primary eruption hazard in the form of pyroclastic flows. Pakem District is one of the areas affected by the eruption. Vulnerability is the situation where a community experiences a decrease in resilience due to a threatening event that jeopardizes their survival and livelihood. Vulnerability analysis aims to reduce disaster risk. The purpose of this research is to map and analyze the social, physical, and total vulnerability resulting from the eruption of Merapi Volcano in Pakem District using the SMCE method. This research employs the Spatial Multi Criteria Evaluation (SMCE) method to create scenarios based on specific criteria. The results indicate that each village has various classifications of social and physical vulnerability classes. Population density is the most significant variable affecting social vulnerability, whereas the estimated losses from housing damage are the most significant variable influencing physical vulnerability. The results of total vulnerability scenarios, including social, physical, and equal, show the same and consistent class classifications. Candibinangun Village, Harjobinangun Village, and Pakembinangun Village are classified as low total vulnerability. Meanwhile, Hargobinangun Village is classified as low and medium total vulnerability, while Purwobinangun Village is classified as low, medium, and high total vulnerability.

This study aims to analyze the spatial distribution of the population of disaster-vulnerable groups in Bantul Regency in 2022. This study used secondary data from the Central Statistics Agency (BPS) with data on infants, toddlers, children, pregnant or breastfeeding mothers, people with disabilities, and the elderly. The collected data is then processed to determine the density intervals of high, medium, and low vulnerable groups. The study results are presented as a spatial distribution map of the density of vulnerable groups. The results showed that areas with a high density of vulnerable groups were in Kasihan and Piyungan sub-districts. Sites with a moderate density of vulnerable groups are in the Banguntapan, Sewon, Bantul, Jetis, and Imogiri sub-districts. Meanwhile, areas with low density of vulnerable groups are in Sedayu, Pajangan, Pleret, Dlingo, Pandak, Bambanglipuro, Srandakan, Pundong, and Sanden Districts. Mapping the spatial distribution of vulnerable group density can determine areas in Bantul Regency classified as highly vulnerable group density to be prioritized first, then medium to low vulnerable group density. Thus, this research can be helpful for Bantul Regency policymakers in carrying out earthquake disaster risk reduction programs for vulnerable groups referring to the results of spatial distribution maps, and it is hoped that this research can be implemented for other regions in Indonesia.Keywords: Spatial Distribution, Disaster-Vulnerable Groups, Bantul Regency.

The construction of the JJLS (Southern Cross Road Network) project in Kulon Progo Regency passes through Kapanewon Galur, Panjatan, Wates, and Temon to connect the Provinces of DIY and Central Java. The development of JJLS infrastructure can lead to the development of residential land and other functional buildings in the surrounding areas (Hendry, 2021). This study attempts to determine changes in land use variability due to the construction of JJLS in Kulon Progo Regency. Based on this information, changes in land use that occur intensively in certain areas can be monitored and detected early, so that appropriate policies can be formulated to prevent uncontrolled changes in land use. The research method used in this study is the interpretation of digital sentinel 2 imagery, which is then overlayed with a land use map to determine land changes that occurred in 2016, 2020 and 2024. Statistical analysis was carried out to determine the effect of JJLS development on land use changes in Kulon Progo Regency, especially in the sub-districts through which JJLS passes. The results of the study showed that there were significant changes in land use in the range of 2016, 2020 and 2024. Based on the results of the RCI calculation in 2016 to 2020, the lowest RCI value was 0,2917 and the highest value was 3,156. While the RCI value for 2020 to 2024 had the lowest value of 0.3862 and the highest was 2,1791. Based on the RCI value, it is divided into 3 classes, low, medium, and high, in order to represent the intensity of change in each village. Based on the results of statistical calculations, it can be concluded that there is a strong influence between the JJLS variable and the growth of built-up land in the research area.
