DESAIN KERJA ? ERGONOMI ?


• Sejarah dimulai pada Perang Dunia II ketika pakar psikologi,

fisiologi, antropologi, dokter, insinyur mulai menggabungkan

teknologi dan ilmu manusia bersama.

• Ergonomi : studi tentang interaksi manusia dan mesin dan faktor

yang mempengaruhi interaksi (Bridger, 2003).

• Ergonom : dari kata Yunani ergon (kerja) dan nomos (hukum)

(Dul and Weerdmeester, 2008).

• Ergonomics ~ Human Factors/Ergonomics (HFE)

• Perancangan/desain kerja : studi prinsip dan teknik untuk

menghasilkan desain kerja terbaik (manusia, material, lingkungan)

efektif, efisien, produktif


Tujuan utama ergonomi dan desain kerja : Untuk

mencapai produktivitas optimal, sekaligus memperhatikan

kesehatan dan keamanan kerja

Ergonomi merupakan

penyebab kecelakaan

kerja terbesar

HUMAN, MACHINE, AND ENVIRONMENT

- Temperature and Climate

- Psychology and Workload

- Control System

- Display System

- Noise and Light

- Display and Tools Optimation

- Material Handling

- Energy Consumption

- Sit Position and Design Concept

- Workplace Design

- Anthropometry

- Physiologycal System


Interaction Evaluation

H > M : control actions by the

human on the machine

Anatomical : cycle time, posture

Physiological : work rate/work

load, fatigue

Psychological : mental workload

H > E : effects of the human on

the environment

Physical : working environment,

standards

M > H : feedback from the

machine

Anatomical : design

Physical : vibration, noise

Physiological : heat

Psychological : meet user

expectations

M > E : machines may alter

environment

Mainly by industrial/site

engineers and industrial

hygienists

E > H : the environment may

influence the human

Physical/physiological : noise,

temperature, lighting

E > M : the environment may

affect the machine

Industrial/site engineers,

maintenance, facilities

management

Anatomical : Posture analysis with

REBA


Physiological : Body temperature

WORK PRODUCTIVITY

• Effective ? Efficient ? Productive ?

• Example : An output standard for a worker to do a job is 250 units in

5 hours (50units/hour). Because of a method mistake, on day A the

worker could only finished 200 units in 5 hours. But on day B, the

worker was so determined that he could finished 250 units in 4

hours.

• Effectivity (units on day A) : 200/250 = 80% degree of

accomplishment (doing the right things)

• Efficiency (time on day B) : (5-4)/5 = 20% inputs usage to

produce standardized outputs (doing things right)

• Productivity (units/hour on day B) : 250/4 = 62.5 units/hour ratio

of outputs to inputs

WORK PRODUCTIVITY

FAKTOR MEMPENGARUHI PRODUKTIVITAS

• Technical factors : work method, work environment,

tools/machines, materials

• Human factors : ability, skill, motivation

• Management factors : wage, treatment, awards and punishment

PRODUKTIVITAS DAN BIAYA

WORK SPEED AND ERROR

1. Two factors as productivity

input :

- Amount/number of outputs

achieved

- Time needed to complete a

job/task

2. Productivity rate increase

must consider quality control

of the product.

Work speed and error are

generally correlated, considering

: age, experience, ability

WHAT IS WORK DESIGN AND ERGONOMICS ?

• “The science of matching the job to the worker, and the product to the

user”

• “The scientific study of human work”

• “Fitting the task/job to the human”

Worker ? User/customer ?
