Abstract — PT Pudak Scientific is a company engaged in the
manufacture of aircraft parts industry. Meeting the precise and
timely demand of aerospace parts from customers becomes a
major corporate responsibility. However, Loss Revenue often
occurs due to engine breakdown. So that cause because the
production target is not achieved, the product reject, and the
delay of delivery. One of the machines that often experience
breakdown is Mori seiki NH4000 DCG. Mori seiki NH4000
DCG is the finishing machine for Blank fork End product. The
demand for this part is quite large, making it a tough task for
the Mori Seiki NH4000 DCG machine. But because the
breakdown of the machine is high enough to cause production
targets every month are often not met. In addition,
Maintenance activities that have not noticed the characteristics
of engine damage, as well as the distribution of historical data
of the machine causing less effective and efficient actions
resulted in substantial Maintenance costs. Based on the results
of risk analysis of Mori Seiki NH4000 DCG engine damage, in
terms of performance loss system caused by a large enough
that is 3.773% of machine production capacity per year. This
figure exceeds the risk acceptance criteria by the company that
is 2%. Therefore it is necessary to find the appropriate
Maintenance policy for the Mori Seiki NH4000 DCG machine.
The approach is to use Reliability Centeres Maintenance and
Risk Based Maintenance. Based on the above two approaches
obtained the appropriate interval time so that the Maintenance
activities more effective and can improve the efficiency of
treatment by reducing the cost of care previously
Rp167.506.286, - per year, to Rp 96.147.061, - per year. With
the policy is expected to reduce engine breakdown and
performance loss caused. So the number of risks that arise for
the future are within the criteria of acceptance set by the
company.

I. INTRODUCTION
PT Pudak Scientific is one of the growing companies
and engaged in manufacturing industry. The company
produces aircraft parts that will be rafted at an aircraft
assembly company later. In the early stages, pudak
company is a company that produces educational
props and laboratory equipment. With a strong
background of "Engineering Department" In the early
years of 2000 PT Pudak Scientific established the
CNC Division to continue to support the quality and
productivity of the products in production. Started
with only 1 CNC machine PT Pudak Scientific
continue to do development by investing for new
machine procurement. In 2005 PT Pudak Scientific is
actively seeking customers and getting some
companies that entrust to Pudak to reproduce the
components they need. In 2006 Pudak Scientific
continues to add high precision turning center
machines, achining centers, measuring instruments
and high precision gauges. In 2007 PT Pudak
Scientific started entering manufacturing for
Aerospace products. In 2008 it was awarded the
Quality Management System - ISO 9001: 2000
certification within the scope of "The Manufacture of
Precision Metal Parts" 2012. Pudak Scientific
successfully obtained certification from NADCAP for
Aerospace Quality System (AQS AC7004) in 2013.
In 2013 Pudak Scientific was awarded the AS9100
Rev .C, which is the Standard Quality Management
System for the Aerospace Industries of the world.
Meeting the precise and timely demand of aerospace
parts from customers becomes a big responsibility of
the company to improve performance from various
aspects especially the production and maintenance of
the production machine itself. However, conditions in
the field are not as easy as schedules and plans that
have been arranged. Loss Revenue occurs frequently
due to engine damage resulting in Product reject,
production targets not achieved, and delivery delay.
The production supervisor says that optimization needs
to be done for resources, especially in production
machinery facilities. Machines that produce the
