  • Role of Coastal Vegetation Belts in Mitigating Tsunami Waves: Bibliometric Analysis, Numerical, and Spatial Analysis Reviewed

    Tsunami is a catastrophic natural disaster that is difficult to predict and often results in significant loss of life and property damage. This study examines the role of coastal vegetation belts in mitigating tsunami wave impacts through numerical and spatial analyses. This study also used bibliometric analysis to support the discussion. Numerical simulations using CADMAS Surf 2D were conducted for various scenarios to assess the effect of vegetation belts on wave speed and height. Spatial analysis using ArcGIS was employed to map tsunami-affected areas, and grid-cell analysis was used to calculate the volume of water entering inland areas during a tsunami event. The results demonstrate that vegetation belts with specific thicknesses and densities significantly reduce wave speed and height, thereby mitigating tsunami energy as it approaches land. These findings emphasize the critical role of vegetation belts in coastal management strategies. Future research should explore integrating natural barriers with artificial infrastructure, such as embankments, to provide comprehensive protection against tsunami impacts.

  • Evacuation route during a disaster with health protocol in the new normal era Reviewed International coauthorship

    The southern coast of Java Island, one of which is Sumbermanjing Wetan District, Malang Regency, is considered prone to the geological disaster tsunami. Sumbermanjing Wetan District is directly adjacent to the Indian Ocean, a seismic gap zone that produces geological processes and high-intensity seismic activity that can trigger tsunami waves. On June 13, 2021, the COVID-19 outbreak in Sumbermanjing Wetan District recorded 90 suspected cases (two were hospitalized and the other 88 were self-isolating at home), and 38 were confirmed positive for COVID-19 (34 recovered and 4 died). This research focuses on evacuation plans for coastal areas from the threat of a tsunami during the pandemic and the new normal era. The sub-variables for determining the shelters include building area, type of building, ease of access, building construction, and capacity. The sub-variables for determining the evacuation route include road class, pavement type, and road width. Meanwhile, the sub-variables for implementing health protocols in the new normal era are maintaining distance, wearing masks, washing hands, special treatment for symptomatic refugees, and implementing other health protocols. The implementation of health protocols in evacuation activities will bring an impact on the reduction of the available shelter's capacity. The study results indicate the need for additional new shelters to implement health protocols in the new normal era. With this addition, it will impact the travel time from the residential areas at risk of tsunami impacts to the shelters. One of the reasons is that the closest shelter to the residential area is already full of refugees, so the refugees have to move and evacuate to the other shelters that can still accommodate them.
