Abstract: PT Pertamina Gas is a company involved in the midstream and downstream sectors of
gas industry in Indonesia that unreleased from problems that have a relation with level of gas
transmission availability which determines the quality and productivity of company in
transmitting gas until arrive to the end users. However, maintenance in turbine machines
frequently conduct reactively which machines fixed if occured a damage (breakdown
maintenance). This is can be seen at availability levels that very fluctuative and declining in
march 2013 and also december 2013. Therefore, maintenance improvement is required with
Total Productive Maintenance approach so that the gas transmission availability will reach the
target. TPM is an innovative approach to maintenance that optimizes equipment effectiveness,
eliminates breakdowns and promotes autonomous maintenance. According to the primary and
secondary data analysis, planned maintenance programs (one of pillar in TPM) are the main
cause of declining the equipment availability in PT Pertamina Gas Western Java Area especially
because of spare part problems.Based on this, in order to have gas transmission avalability reach
the target, company needs to conduct Total Productive Maintenance program which include
focused maintenance, autonomous maintenance and planned maintenance.
