Abstract

Sea level rise due to climate change and land subsidence in coastal areas have increased the frequency of tidal flooding, especially in Indonesia. Conventional embankments that are generally used to hold back seawater have limitations in adapting to fluctuations in water levels. This study evaluates a floating fiber embankment as an innovative solution for tidal flood mitigation. The embankment is designed to automatically adapt to changes in sea level using elastic and corrosion-resistant fiber materials. Numerical simulations based on the finite element method (FEM) were performed using ANSYS software to analyze the stress, strain, and deformation of the floating fiber embankment under hydrostatic pressure. The simulation results showed a maximum stress of 8231 x 10^6 Pa with a maximum deformation of 0.43 meters. Laboratory experiments using a 1:20 scale prototype validated the simulation results, with a maximum stress of 8210 x 10^6 Pa and a maximum deformation of 0.41 meters. The results showed that the floating fiber embankment has good adaptive capabilities in resisting hydrostatic pressure and functions automatically without requiring manual intervention. This technology has the potential to be an effective and sustainable solution for tidal flood mitigation in coastal areas, especially in areas that often experience land subsidence and sea level rise due to climate change.

Abstract

Inaccuracy in planning project activities during project implementation greatly affects implementation delays in the field. The purpose of the study is to determine and analyze: (1) the causal factors that contribute to project completion delays, (2) the causal factors that contribute to the dominant delay in project completion, and (3) delay risk management. In the Sports facilities (Eastern Tribune Development) project. Cirebon Regency. This study is a type of quantitative descriptive study. Data collection was done through FGD, interviews and questionnaires distributed to 10 qualified respondents in the construction sector. The resources of this study are the cause of the delay in the completion of the projects. A House of Risk (HOR) approach was used to analyze the data. Research results show that (1) Cirebon Regency Sports Facilities Building (Eastern Tribune Development) project has 14 risk events and 17 identified risk causes that cause delays. (2) Control factors that cause delays in project completion include: material factors, contract document factors, project owner factors, and contractor and design consultant factors, and (3) delay risk management options, including: (a) good communication and coordination. with the owner; (b) apply a comprehensive planning approach to procurement of materials, (c) coordinate current project drawings between consultants and field workers, (d) contact consultants and supervisors.
