Abstract

Dalam bisnis perindustrian saat ini, perusahaan dituntut untuk selalu
meningkatkan kualitas produk dan meningkatkan performansi kinerja perusahaan
dengan selalu melakukan perbaikan (improvement). Bagi perusahaan manufaktur
sektor yang paling penting untuk ditingkatkan performansinya adalah di sektor
produksi. Persaingan antar perusahaan juga semakin ketat karena akibat
pemberlakuan perdagangan bebas saat ini ditambah dengan life cycle produk yang
semakin singkat disertai meningkatnya harapan konsumen terhadap produk.
Perusahaan yang harus menerapkan perbaikan adalah PT Loka Refractories.
Perusahaan ini adalah perusahaan yang bergerak dalam industri batu tahan api. Di
perusahaan ini, lead time dari proses produksi cukup panjang dikarenakan masih
adanya non value added activity yang terjadi. Non value added activity ini
mengakibatkan terjadinya waste di perusahaan, seperti defect pada pembakaran,
waiting karena mesin rusak, excess processing akibat proses yang berulang dan
rework, overproduction serta inventory yang tinggi. Untuk menghilangkan non
value added activity, digunakan tool Lean Manufacturing untuk mengidentifikasi
aktivitas apa saja yang tidak memberikan nilai tambah dan mengeliminasinya.
Non value added activity di perusahaan terdapat pada proses persiapan bahan,
pembentukan dan pembakaran. Kemudian diketahui tiga waste kritis yang harus
diperbaiki, yaitu defect, waiting dan inventory. Kemudian dicari akar penyebab
permasalahan dari ketiga waste tersebut. Setelah itu dilakukan perbaikan dengan
alternatif perbaikan yang terpilih adalah memberikan pelatihan kepada staff PPC
dan Quality Control dengan harapan dapat memperbaiki kondisi eksisting
perusahaan serta penambahan divisi maintenance untuk melakukan perawatan dan
perbaikan mesin.

Nowadays, in industrial business, a company should to increase product
quality and increase a company competitive advantage. To reach those goals, a
company should do a continuous improvement all the time. The most important
aspect to be increased is a production aspect. Besides that, the competition
between companies become more challenging due to implementation of free trade
regulation and product life cycle that become shorter day by day. Moreover, in
this era, the customer expectation about product quality is higher than past. One
of the companies that should do some improvement is PT Loka Refractories. PT
Loka Refractories is a company that produces a refractories product. In this
company, production process lead time is quite long because of non-value added
activity. Non value added activity causes waste such as defect on burning process,
waiting that caused by broke of machine, excess process that caused by rework
process, overproduction and high number of inventory. To eliminate non value
added activity, this research uses Lean manufacturing concept to identify
activities that cannot give value added for product. Non value added activity in
PT Loka Refractories happened on raw material preparation process, forming
process and burning process. There are three critical waste that should be
improved, defect, waiting and inventory. After identify the waste, this research
identify the root cause from it. The last step is suggesting the improvement step
for company. The chosen improvement step that suggested by this research is:
Give some training to PPC and QC staff with expectation to fix and improve the
company performance and additional maintenance division to do the treatment
and repair of machines.
