Assessing Environmental Physics: Tidal Flood Impact with Multidiscipline Approach (Case Study Coastal Cities Semarang Indonesia)

Abstract

Tidal floods and land subsidence often occur in the coastal areas of Semarang, Central Java. The coastal area of Semarang has an essential role in the economy of the city of Semarang, especially the Port of Tanjung Emas. Research with a multidisciplinary approach is expected to obtain conclusions on technical and non-technical problems to prepare mitigation measures and reduce the risk of tidal flooding. This study aims to determine and analyze the impact of tidal flooding in the city of Semarang using a multidisciplinary approach. The data used for the analysis came from literature studies and field observations. This research method is descriptive analysis. The results showed that the tidal flood caused damage to infrastructure, houses, and other public facilities. This damage makes the infrastructure not function optimally. Other impacts the community feels are disruption of economic activities, lower productivity, and increased maintenance costs, thereby reducing overall community income. Therefore, tidal flood prevention is needed from all stakeholders, both individually and collectively.
