Summary: | A bridge is one of land-base transportation facilities that has important role as
a connector between two regions separated by river or sea, so that it is fitting to do
planned and scheduled preventive maintenance on bridges.Mistakes in
determining interval preventive maintenance on bridges will result in the high
level of damage on bridges� components. The high level of damage on bridges�
components will impact directly on the maintenance costs incurred and low level
of bridges� reliability, thus it is appropiate to determine interval optimum
preventive maintenance on bridges to preserve bridges� reliability and minimize
maintenance costs. There are several methods that is possibly used in determining
interval preventive maintenance such as algorithm, genetic, markov chain and
sensor using.The method used in this research is markov chain because markov
chain can predict components� damages in the future periods, besides that,
application requirements of markov chain in reliability system are able to be
fulfilled by bridges� components damage characteristics.
The result of this research is in the form of software that is named
BRIPMAC. BRIPMAC is a manifestation of modeloptimization that is developed
to determine the interval optimum preventive maintenance on bridges based on
markov chain analysis.This research succeeds in building a model to determine
interval optimum preventive maintenance on bridges based on markov chain
analysis by considering minimum maintenance costs and critical components
reliability this research also facilitates this model in the form of software.
Software making is done by using MATLAB R2010a software and for the model
physical apperance is made using Graphic User Interface (GUI) contained in
MATLAB software.The developed software testing was done in Krasak bridge
that is one of bridges that is managed by National Road Implementation Unit
Daerah Istimewa Yogyakarta Province Region (SATKER PJN DIY). The result of
BRIPMAC testing on the case study of Krasak bridge shows 3 critical
compontens which are pillar, girder, and abutment. Result analysis that is done by
BRIPMAC software determines the interval of regular maintenance Krasak bridge
in the year of 2013 is 280 days. After comparing the regular maintenance cost and
critical components reliability between interval optimum that is recommended by
software and regular maintenance that is set by the government in the year of
2013, the efficiency of the regular maintenance cost is in the amount of
23,44%.Besides that, reliability improvement is resulted in every components in
the amount of 6.269% for pillars, 5.247% for girder, and 5.52% for abutment. |
