Definisi Teknik Industri*

• Teknik Industri berkaitan dengan perancangan, perbaikan dan penginstalasian sistem integral yang terdiri atas manusia, bahan, peralatan, informasi dan energi.

• Teknik Industri menggunakan pengetahuan dan keahlian dalam ilmu-ilmu matematika, alam dan sosial secara bersama-sama dengan prinsip-prinsip dan metoda-metoda analisis dan perancangan kerekayasaan untuk menentukan, memprediksikan dan mengevaluasi hasil-hasil yang diperoleh dari sistem integral tersebut.

Sistem

dalam Kontek Pengambilan Keputusan

• Sistem is kumpulan komponen-komponen yang

terorganisasi dan berhubungan untuk melakukan

sesuatu yang tidak dapat dilakukan sendiri pleh satu

komponen saja.

• Kita gunakan model sistem sebagai cara yang tepat

untuk melihat sesuatu dalam rangka tujuan pengambilan

keputusan (memecahkan masalah)

15Sistem Manufaktur


UNIJOYO

Sistem

dalam Kontek Pengambilan Keputusan

• A System is described by:

• Observer: Who is interested in the system? Observer

• Purpose: Why define the system? Improve, output of interest

• Environment: outside the system. Define the system boundary

• Hierarchy: components and/or sub-systems are organised

• Inputs: Affect the system but are not affected by it. Can be

controllable or uncontrollable. Decision variables/parameters

• Outputs: Are affected by the system. These are of interest to

the observer. Include measure of success

• Components: Both affect and are affected by the system.

• Relationship/transformation process: Between system

inputs, outputs and components –relevant aspects.

16Sistem Manufaktur


UNIJOYO

Aplikasi Berpikir Sistem (1)

• Berpikir tentang fenomena secara hirarki yang

tergorganisasi keseluruhan.

• Identifikasi beberapa prinsip umum yang memungkinkan

sistem dapat didefisnisikan dan tentukan batas-

batasnya.

• Penentuan input dan input yang melintasi batas sistem

(system boundary).

17Sistem Manufaktur


UNIJOYO

Aplikasi Berpikir Sistem (2)

• Identifikasi mekanisme pengendalian dengan cara apa

sistem mempertahankan identitasnya dan hubungannya.

• Identifikasi tujuan sistem (purpose or goals), dan

komponen-komponennya, atau sub-sistem

18Sistem Manufaktur

A Systems View of Manufacturing

• Manufacturing can be viewed either as a transformationprocess or as a system.

• As a Transformation Process: A narrow definition ofmanufacturing is that it a process of transformationwhere raw material are converted into products.

• As a System: Manufacturing is not limited to materials transformation performed in a factory. Rather, it is a complex system comprising of several elements.

• This involves an internal environment and an

external environment.

• The inputs are from the external environment

and involve several variables.

• The outputs are to the external environment and

also involve several variables.

Definisi manufacturing

• CIRP (International Conference on

Production Engineering), 1983:“A Series of interrelated activities and operations

involving the design, materials selection, planning,

manufacturing production, quality assurance,

management and marketing of products of the

manufacturing industries”.

23Sistem Manufaktur

Definisi Manufaktur dan Produksi

• Kata manufacturing diartikan lebih luas

• Manufacturing adalah proses konversi suatu desain menjadi produk

akhir

• Production adalah aktivitas fisik untuk mengubah suatu bentuk

material menjadi bentuk lain yang lebih bernilai

Sistem Manufaktur

• Sistem manufaktur adalah sistem yang melakukan proses transformasi/konversi keinginan (needs) konsumen menjadi produk jadi yang berkualitas tinggi

• Keinginan konsumen diketahui dari studi pasar, yang kemudian keinginan ini diterjemahkan menjadi desain produk, dan kemudian menjadi desain proses

• Komitmen terhadap kualitas

• Kualitas produk harus dimiliki oleh setiap level dalam perusahaan pada setiap tahap proses produksi

• Dalam proses transformasi ini terjadi pertambahan nilai

28Sistem Manufaktur


UNIJOYO


• Can be viewed from three different Aspects:

1. Technical: Dealing with engineering, science and

technology issues.

2. Commercial: Dealing with financial, marketing, legal

issues

3. Management: Dealing with planning, operations and

other related issues such as information. And also

organisational issues dealing with human related issues.

29Sistem Manufaktur

MANUFACTURING: DIFFERENT

PERSPECTIVES

• It can also be viewed from three different

perspectives:

– Firm level,

– Industry level and

– Regional or global level.

30Sistem Manufaktur


UNIJOYO

Firm Level

• Manufacturing at the firm level involves

several variables which can be broadly

grouped into the following three

categories:

– Technical

– Commercial

– Management

31Sistem Manufaktur


UNIJOYO

Technical

• The technical side has been discussed

before and involves various issues

related to the science, engineering and

technology aspects of manufacturing.

32Sistem Manufaktur


UNIJOYO

Commercial

• The commercial side deals with issues such as costs,

sales, revenue and profits. Each of these involves many

variables.

• For example, the costs can be investment costs, unit

manufacturing costs, cost of rework and so on. The

basic bottom line for a firm is that it must make

reasonable profit for its investment.

33Sistem Manufaktur


UNIJOYO

Management

• Deal with managing the various activities atstrategic and operational levels taking intoaccount the many different legal and socio-political aspects and various constraints.

• Another very important issue relates to theorganizational side that deals with the humanrelated issues – organisational structure,communication and flow of information, skillbase of the workforce and so on.

34Sistem Manufaktur


UNIJOYO

National Level

• In the national level, a manufacturing firm is influenced

by factors such as market competition and government

policies.

• Obviously, the market competition is not only determined

by manufactured goods within the nation but also

affected by imported manufactured goods.

35Sistem Manufaktur


UNIJOYO

National Level

• Some of the government policies that affect themanufacturing enterprise are indicated below.

• Industry or Technology development policies,

• Taxation policies,

• Environmental policies.

• Trade policies – export and import subsidies, protection

• Financial investment

36Sistem Manufaktur


UNIJOYO

Regional and Global Levels

• Manufacturing at the regional and global levels deals

with the following factors :

• Fierce competition

• Open market - free trade

• Trade organisation - regional partnerships

37Sistem Manufaktur


UNIJOYO

A THREE LEVEL MODEL OF

MANUFACTURING

• Manufacturing is a complex system involving several

elements. It can be viewed as a three level system

(Level 1 - 3)

• Note that Level 1 is nested within Level 2, in turn, is

nested within Level 3. We briefly discuss the elements at

each of these levels.

Level 1

• This level corresponds to the shop floor

level and has three key elements - Inputs,

Process and Outputs.

40Sistem Manufaktur


UNIJOYO

Level 2

• This level includes Level 1 as well as six new elements.

The focus of this level is management of business at the

operations level and the six new elements with a range

of operational issues.

41Sistem Manufaktur


UNIJOYO

Level 3

• This level includes the Levels 1 and 2 and six new

elements. Here, the management focus is long term and

strategic.

• This is important, as survival of businesses in the fiercely

competitive global market requires long term strategies.

The six new elements deal with a range of long term

issues.
