ABSRTAK
PT. Putra Nugraha Sentosa (PNS) merupakan perusahaan yang bergerak dibidang
percetakan buku dan packaging. PT PNS memiliki 2 lantai produksi yang berfokus pada
cetak offset sheat dan roll. Lantai cetak offset sheat memiliki permintaan yang stabil pada
jenis produk kemasan dan sampul sehingga intensitas produksinya cukup padat. Pada
lantai produksi cetak offset sheat memiliki 2 mesin cetak yang memproduksi produk cetak
sampul buku dan kemasan. Berdasarkan observasi yang dilakukan bahwa mesin yang
sering mengalami permasalahan dan menggangu production timing yaitu mesin Heidelberg
CD 102. Mesin cetak Heidelberg CD 102 pada Tahun 2021 mengalami kegagalan selama
81,63 jam dan frekuensi kerusakan sebanyak 54 kali dengan sumbangsi sebesar 77% dari
total downtime lantai offset sheat di tahun 2021. Meskipun penerapan perawatan preventif
telah diterapkan oleh PT. Putra Nugraha Sentosa, namun fakta di lapangan belum
maksimal. Penelitian ini diharapkan dapat meningkatkan keandalan mesin.
Reliability Centered Maintenance adalah metode yang digunakan pada penelitian
ini. Metode perawatan ini menggunakan informasi yang berkaitan dengan keandalan suatu
mesin/komponen untuk memperoleh strategi perawatan yang optimal dan mudah untuk
dilaksanakan. Informasi tersebut diantaranya sistem kerja, batasan sistem, fungsi sistem
dan kegagalan fungsional pada mesin. Berdasarkan hasil analisis kegagalan dan
perhitungan Risk Priority Number menggunakan Failure Mode and Effect Analysis
didapatkan komponen yang paling kritis.
Hasil analisis metode Reliability Centered Maintenance diperoleh komponen
paling kritis adalah SLT card modul, Selenoid valve, Selang pneumatik, Pneumatik impresi
dan Bearing. Setelah dilakukan perhitungan interval waktu perawatan komponen diperoleh
interval perawatan SLT card modul 279,19 jam, Selenoid valve 250,38 jam, Selang
pneumatik 235,03 jam, Pneumatik impresi 183,07 jam dan Bearing 622,57 jam. Setelah
dilakukan reliability pada komponen tersebut maka terjadi peningkatan pada komponen
SLT card modul sebesar 66,65%, Selenoid valve sebesar 98,91%, Selang pneumatik
sebesar 89,09%, Pneumatik impresi sebesar 97,84% dan Bearing 74,04%.

ABSTRACT
PT. Putra Nugraha Sentosa (PNS) is a company engaged in book printing and
packaging. PT PNS has 2 production floors that focus on sheet and roll offset printing. The
offset sheet printing floor has a stable demand for types of packaging and cover products
so that the production intensity is quite dense. On the offset sheet printing production floor,
there are 2 printing machines that produce book covers and packaging. Based on
observations made that the machine that often experiences problems and interferes with
production timing is the Heidelberg CD 102 machine. The Heidelberg CD 102 printing
machine in 2021 failed for 81.63 hours and the frequency of damage was 54 times with a
contribution of 77% of the total floor downtime. offset sheet in 2021. Although the
implementation of preventive maintenance has been implemented by PT. Son of Nugraha
Sentosa, but the facts on the ground are not optimal. This research is expected to increase
the reliability of the machine.
Reliability Centered Maintenance is the method used in this research. This
maintenance method uses information related to the reliability of a machine/component to
obtain an optimal maintenance strategy that is easy to implement. The information includes
work systems, system limitations, system functions and functional failures on the machine.
Based on the results of the failure analysis and the calculation of the Risk Priority Number
using the Failure Mode and Effects analysis, the most critical components were obtained.
The results of the analysis of the Reliability Centered Maintenance method
obtained that the most critical components are the SLT card module, Selenoid valve,
pneumatic hose, impression pneumatic and bearing. After calculating the component
maintenance time interval, the SLT card module maintenance interval is 279.19 hours,
Selenoid valve 250.38 hours, Pneumatic hose 235.03 hours, Pneumatic impression 183.07
hours and Bearing 622.57 hours. After reliability was carried out on these components,
there was an increase in the SLT card module component by 66.65%, Selenoid valve by
98.91%, Pneumatic hose by 89.09%, Pneumatic impression by 97.84% and Bearing
74.04%.
