Abstract

Natural disasters such as droughts occur gradually and last until the start of the rainy season. Meteorological drought happens when a region experiences periods of below-average rainfall, resulting in lower water availability in the soil compared to its needs. The Tangsi Sub-Watershed traverses the districts of Kajoran, Salaman, Kaliangkrik, Borobudur, and Tempuran. It is part of the Progo Watershed, which is under the administrative boundary of Magelang Regency. The variation in climate and the landforms of the Tangsi Sub-Watershed, which are dominated by materials that are less permeable to water, make this area prone to drought. This research analyzes meteorological drought in the Tangsi Sub-Watershed, Magelang Regency by using the Standardized Precipitation Index (SPI) and Drought Hazard Index (DHI). The analysis from quarterly SPI from 1994 to 2023 indicates that the Tangsi Sub-Watershed experienced a medium drought hazard level with a score of 14. The Tangsi Sub-Watershed experienced extreme drought events at 2.22%, high drought at 3.89%, and moderate drought at 6.94%. Long-term drought risk analysis can be used by communities and governments to plan and implement mitigation measures ahead of time by revealing patterns and intensities of recurrent droughts.

Abstract

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.
