| Summary: | PT. Kereta Api Indonesia (Persero) operates aling-aling train to provide
protection for trains passenger in case of collision between trains is occur. Alingaling
Train functioned as a protective cover collision energy absorber operated in
Indonesia. The operational of aling-aling train has several weaknesses, among
other: aspects of technical, operational and economical. United States has
developed a train collision energy absorbing devices, named Crash Energy
Management (CEM). CEM tool has conducted trials on collision between a train
and obtained results that are very effective tools to reduce the damage level of the
train when the collision occures. This research compares aling-aling train with
CEM equipment with the aim of analyzing the impact of a collision that occurred
on the level of damage to the train/carriages, examined the technical operation of
aling-aling train, and the advantages and disadvantages then evaluate the results
oft he comparison between aling-aling train with CEM equipment
Comparison between aling-aling with CEM equipment using Multi
Criteria Analysis method to determine the advantages and disadvantages of each
as a train collision energy-absorbing technology. Criteria used in this comparison
is the impact of a collision, ease of implementation, the basic application and the
economic impact. Comparisons were made with two scenarios namely in the first
scenario each criterion is given equal weight 25% and in the second scenario are
given different weights according to the scale of priorities (40% collision impact,
ease of application of 30%, the basic application 15% and the economic impacts
15%).
Comparison of the first scenario generate the value 15.042 for CEM and
11.708333 for aling-aling train. Comparison of the second scenarios produce
values 14.075 for CEM and 9.975 for aling-aling train. Based on these
assessments the CEM equipment has advantages over the aling-aling as the train
collision energy absorber.
