Why IE Was Born ?

• As a Result of Industrial Revolution

• Need for Technically Trained People Who Could Plan, Organize, and Manage the Operations of Large Complex System

• Need to Increase Productivity and Efficiency of Operation System

Pioneers Of IE

• Adam SMITH

• Charles BABBAGE

• Eli WHITNEY

• Henry TOWNE

• Frederick W TAYLOR

• Frank B GILBERTH

Adam SMITH (1723-1790)

Wealth of Nations (1776)

Specialization of Labor– Division of the task in pin making into 4

separate operations increased output by a factor of almost 5

– 10 worker could produce 48.000 pins per day

Page 19: Pti 1

Adam Smith (1723-1790)

Keuntungan adanya pembagian kerja dengan memberikan contoh

sebuah pabrik jarum. Di dalam pabrik jarum tersebut seorang

buruh secara pasti dapat membuat 20 buah jarum sehari. Dari

hasil kunjungan Smith atas suatu pabrik jarum yang telah

melakukan pembagian pekerjaan, ternyata 10 orang buruh dapat

membuat 48.000 buah jarum, dengan pembagian pekerjaan yaitu

ada yang khusus menarik kawat, ada yang khusus memotongnya

dan ada yang khusus meruncingkan jarumnya, serta lainnya.

19

Page 20: Pti 1

Dari keadaan tersebut dapat dikemukakan bahwa pembagiaan pekerjaan yang dilaksanakan itu dapat mempertinggi hasil produksi setiap buruh dari 20 buah menjadi 4800 buah jarum atau meningkatkan sebanyak 240 kali lipat.

20

Page 21: Pti 1

Pembagian pekerjaan sering dibedakan menjadi

dua pengertian, yang pertama adalah membagi

pekerjaan menjadi sederhana sehingga semua buruh

dengan tingkat keahlian tertentu dapat melakukan

pekerjaan. Pengertian yang kedua adalah pembagian

pekerjaan bersusun yang membagi pekerjaan suatu

kegiatan produksi menjadi beberapa bagian.

21

Page 22: Pti 1

Di dalam perkembangannya, konsep pembagian pekerjaan terus berkembang dan terarah kepada kegiatan pekerjaan yang terspesialisasikan, dan di dalam kegiatan produksi yang lebih modern terjadi pembagian pekerjaan sistem ban berjalan (”conveyor system”).

“Produksi masal mobil oleh Ford sendiri juga terinspirasi dari konsep pembagian pekerjaan, sehingga ongkos produksi semakin murah. Dengan ongkos produksi yang lebih efisien, harga yang ditawarkan dapat lebih kompetitif dengan produk lain. Saat ini konsep pembagian pekerjaan telah digunakan secara luas di hampir seluruh sektor industri.”

22

Page 23: Pti 1

Keuntungan pembagian pekerjaan

1. Setiap orang dapat melakukan pekerjaan yang sesuai dengan bakatnya.

2. Dapat meningkatkan pengetahuan di dalam pekerjaan tersebut sehingga lebih mantap.

3. Orang yang bersangkutan mengerjakan pekerjaan yang sama secara berkelanjutan sehingga dapat menghindarkan kehilangan waktu, ini berarti semakin efisien.

Charles BABBAGE (1832)

On the Economy of Machinery and Manufacture (1832)

– motion and time study– division of labor

• Result of factory visit in England and USA(early 1800)• Observed the manufacture of straight pins that:

– involve 7 distinct operations– measured the cost and time of performing each operation

Money Could Be Saved Using Woman and Children

• Critics : Do not attempt to improve the work methods or reduce the operation time

Page 25: Pti 1

Charles Babbage (1832)

Menulis buku :

1.“On the Economy of Machinery and manufacturers”

Membuat prototipe:

2.“different engine”

(prototipe kalkulator mekanis); serta

3.“analytical engine” (prototipe komputer).

25

Page 26: Pti 1

Eli Whitney

Konsep Produksi “interchangeable”dan

Konsep Produksi Massal

(Mass-Production)

Melalui Pembuatan Cetakan (die mould).

Henry TOWNE

The Engineer As Economist (1886)

Stressed the Need for Engineers to Be Concerned With the Profitability Effect of Their Decisions

Page 28: Pti 1

Henry Towne (1886)Menulis paper

“The Engineers as Economist”

Dalam jurnal Transaction of ASME yang menekankan perlunya engineer untuk memperhatikan aspek ekonomis (costs/profits) dalam setiap proyek teknis maupun keputusan yang diambil.

28

Frederick Winslow TAYLOR(1856-1915)

FW Taylor was Influenced by Towne and Wentworth

• 1874 : Machinist Apprentice in the Hydraulic Work

• 1983 : Mechanical Engineer From Stevens Institute and

Work at Midvale Steel Company

• 1881 : Began Study of Metal Cutting

• 1895 : Presented “A Piece Rate System” at ASME Meeting

• 1903 : Presented “ Shop Management”

• 1909 : Presented “ Principle of Scientific Management”

Page 30: Pti 1

Frederick Winslow TAYLOR(1856-1915)

• 1895 – menyajikan paper “A Piece of Rate System” pada pertemuan ASME.

• 1903 – menyajikan “Shop Management” yang menyangkut beberapa prinsip dan konsep mengenai methods study, time study, standardization of tools, planning department, classification systems for parts and products, routing system, dll. Tanggapan kurang positif.

30

Page 31: Pti 1

Frederick Winslow TAYLOR(1856-1915)

• 1907 – menulis makalah panjang (200 halaman) berjudul “Study of Metal Cutting” pada Transaction of ASME (rumus Taylor yang terkait dengan biaya produksi dan umur pahat).

• 1909 – menulis “The Principles of Scientific Management” yang sangat kontroversial dan fenomental : (1) menaikkan output produksi sekaligus menurunkan biaya operator, namun juga menaikkan gaji/upah mereka, (2) melatih operator dan meminta mereka bekerja pada kemampuan maksimal untuk kenaikan upah (bonus/insentif) yang melebihi standard.

31

Page 32: Pti 1

Principle of Scientific Management

1. Develop a science for each element of a man’s work, which replaces the old rule of thumb method

2. Select scientifically and then train, teach, and develop the workman, whereas previously he chose his own work methods and trained himself as best as he could

3. Cooperate heartily with the men so as to ensure that all of the work being done is in accordance with the principles of the science which has been develop

4. There is almost an equal division of the work and the responsibility between management and the workmen. The management takes over all work for which they are better fitted than the workman.

Page 33: Pti 1

Empat Prinsip Manajemen Ilmiah-Taylor

1. Buatlah ilmu untuk tiap elemen pekerjaan dengan standardisasi penerapannya dan metode kerja yang efisien

2. Lakukan seleksi karyawan secara ilmiah, yakni sesuaikan keahlian dan kemampuan karyawan dengan jenis pekerjaan yang ditekuninya, lalu didik dan latih karyawan tersebut dengan cara yang paling efisien.

33

Page 34: Pti 1

3. Pastikan karyawan bersikap kooperatif dengan cara memberikan insentif, dan sediakan lingkungan kerja yang dapat mendorong terciptanya hasil kerja yang optimal melalui cara-cara yang ilmiah.

4. Bagilah tanggung jawab kerja antara tanggung jawab managing dengan tanggung jawab working (pelaksana) sembari mendukung individu-individu pada tiap kelompok kerja untuk mengerjakan apa yang mereka paling mampu kerjakan.

Frank & Lillian Gilbreth (1868 -1924)

• Frank Gilbreth (1868 -1924)

• Sambil bekerja sekaligus mengevaluasi dan memperbaiki sistem kerjanya sendiri.

• Meningkatkan produktivitas hampir tiga kali lipat hanya dengan cara mengurangi gerakannya dengan mengatur lokasi/ penempatan bahan baku.

• Menganalisa kerja dan menyusun klasifikasi gerakan kerja mikro (micro-motion study) dengan mengintroduksi elemen-elemen gerakan Therbligs.

• Lillian Gilbreth (1878-1972)

• Istri dari Frank Gilbreth, seorang doktor psikologi.

• Mengkoreksi pendekatan yang menempatkan manusia sebagai bagian dari “mesin kerja” dengan lebih menekankan pada aspek perilaku (behavior) manusia.

Industrial Engineering ?

Industrial Engineering Is Concerned With the Design, Improvement, and Installation of Integrated Systems of

People, Material, Information, Equipment, and Energy. It Draws Upon Specialized Knowledge and Skill in the

Mathematical, Physical, and Social Sciences Together With the Principles and Methods of Engineering Analysis and Design to Specify, Predict, and Evaluate the Results to

Be Obtained From Such System
