Abstract
During floods disaster in the heavy populated residential area, the lack of existing life saving appliances system such as rubber boat and wooden boat were not able to evacuate the disaster victims spontaneously in mass. The condition might be explained since the rubber boat and wooden boat have limited occupant capacity. Based on the conditions, the main objectives of the research are focused on the evaluation of the application of modular floating pontoon as multipurpose floating equipment to support floods disaster evacuation process. The investigation of the modular floating pontoon performance such as hydrostatics characteristics, the equilibrium condition and the intact stability was studied using strip theory and Krylov’s method. Furthermore, the strength analysis of the modular floating pontoon structure was calculated using finite element method. The results show that the modular floating pontoon is reliable to support the evacuation process.
Highlights
Indonesia has many regions which are very susceptible to floods
The second group was the curves that indicating substantially constants that used to determine the characteristics of initial stability and the equilibrium condition of the modular floating pontoon, such as: W (Displacement), WPA (Water Plan Area), TPC (Ton per Centimeter Immersion) and MTC (Moment to change trim one centimeter)
These curves were part of the documentation that must present the characteristics of the pontoons and were used in calculations related to the operation of the modular floating pontoon
Summary
Indonesia has many regions which are very susceptible to floods. In 2013, the Jakarta business center area such as Thamrin and Sudirman Street were swamped by floods. The extremely high rainfall may lead to ecological disasters such as: floods, the shutdown of economics activities and crisis of freshwater. The floods in Jakarta, instead of the heavy rain since December 2012, was caused by the poor drainage systems, the many embankments collapse and the water current volume increased through the 13 rivers across the city. The surrounded regions such as: Bogor, Bekasi, Depok, Tangerang undergo the same circumstances. It is confirmed that the total of disaster victims became 20 persons died, and 62.819 persons were relocated, [2]
