Analysis of Tidal Flood Management in the Coastal Region, West Aceh Regency

Abstract

Tidal flooding in Gampong Pasir Village, West Aceh Regency, reached 100 cm in July 2020, submerging 42 houses. Efforts like buis concrete, sandbags, and tetrapods have been used to address the issue. This study aims to determine the public’s perception of the efforts to overcome tidal floods that have been carried out in Gampong Pasir. This study uses primary data to assess the response efforts and secondary data, including population, research location, and building data. The first questionnaire processes public perception using a Likert scale, while the second processes expert opinions using Analytical Hierarchy Process (AHP). This study interviewed 81 respondents from a total of 418 residents in the community with three expert opinions. The study results indicate that the efforts made have had a positive impact on mitigating tidal flooding in Gampong Pasir, but they are still not optimal. Using the AHP method, the study prioritizes resilience as the highest criterion with a value of 0.75 and identifies Tetrapod as the top-performing alternative with a value of 0.76. Therefore, Tetrapod has been built as a priority structure to address tidal flooding in Indonesia.
