Abstract

The Semeru Volcano eruption on December 4, 2021 caused damage to social, economic and environmental aspects. The Rejali Watershed (DAS) is one of the areas severely affected due to the eruption. The eruption resulted in 51 deaths, 10,565 displaced people, 1,027 houses damaged, two connecting routes and 43 public facilities damaged. This study mapped the disaster risk areas due to the eruption of Semeru Volcano. This research used Laharz to analyze the lava flow hazard map and weighting for social, economic, physical, environmental, and capacity vulnerability parameters. The results showed that the risk level of Semeru Volcano eruption is divided into three classes: high,  medium, and low risk. The high-risk area is 8915.09 Ha (14 %), the medium-risk area is 2174.74 Ha (17 %), and the low-risk area is 1885.60 Ha (69%). The high and medium risks were located on the upper and middle slopes of the Rejali watershed because the upstream area experiences a narrowing of the river flow (bottleneck) due to direct borders with structural land. The Semeru Volcano disaster risk map results can be used as a reference in sustainable risk management efforts in the Rejali watershed to reduce the impact and damage caused by the eruption.

Abstract

The series of volcanic activities of Mount Raung triggered primary and secondary hazards in the area around the volcano. Kalibaru watershed is one of the areas prone to landslides due to secondary hazards of eruption activity in the direction of west and northwest part of this region. This study aims to optimize tourism by mapping landslide hazard using Spatial Multi-Criteria Evaluation (SMCE) around Mount Raung. This research used 46 points of landslide data through remote sensing, field observation. Ten landslide triggering factors, namely TPI (Topographic Position Index), TWI (Topographic Wetness Index), SPI (Stream Power Index), slope, distance to river, rainfall, geology, land use, distance to road, and soil type was used to map the landslide hazard. This study used ROC (Receiver Operating Characteristic) analysis to validate the landslide susceptibility mapping with an AUC (Area Under Curve) value of 0.93, which indicates that the mapping has a high accuracy value. The results showed that the landslide susceptibility is divided into three classes: high susceptible, moderate susceptible, and low susceptible. The high susceptible area covers 151.62 km2 (21%), the moderate susceptible area covers 407.99 km2 (56%), and the low susceptible area covers 166.79 km2 (23%). Based on the results of the mapping, tourism development in the area of Mount Raung is recommended in areas that are classified as medium and low landslide susceptibility.Keywords: Mount Raung, Landslides, SMCE, Tourism Development

Abstract

Aims: This study aimed to develop an approach for disaster risk reduction in urban communities of the indigenous community in Kampung Kuta, West Java, to enhance disaster literacy. The primary issue addressed was the insufficient integration of traditional knowledge into formal disaster education, limiting the effectiveness of disaster preparedness in local communities. Methodology and Results: The study highlighted the inadequate integration of traditional knowledge into formal disaster mitigation, hampering the effectiveness of disaster preparedness in indigenous communities. A qualitative approach was employed, involving interviews, observations, and focus group discussions (FGDs) with local indigenous leaders and community members. The results reveal that Kampung Kuta's indigenous knowledge offers valuable practices for disaster mitigation, such as environmental management and communal responsibility, which could be integrated into formal mitigation frameworks. Transforming these traditions into resilience learning strategies could significantly enhance disaster literacy, fostering greater awareness and resilience within the community. The novelty of this research lies in the fusion of traditional and modern educational strategies, creating culturally relevant disaster education approaches that preserve indigenous knowledge and enhance its application in contemporary disaster management. Conclusion, Significance, and Impact: This strategy provides a viable model for other regions with strong traditions of local wisdom, contributing to the global discourse on integrating indigenous practices into disaster risk reduction (DRR) frameworks, especially in areas prone to natural disasters.
