DESAIN KERJA ? ERGONOMI ?
DESAIN KERJA ? ERGONOMI ?
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
DESAIN KERJA ? ERGONOMI ? Tujuan utama ergonomi dan desain kerja : Untuk mencapai produktivitas optimal, sekaligus memperhatikan kesehatan dan keamanan kerja
Ergonomi merupakan penyebab kecelakaan kerja terbesar
LINGKUP PERANCANGAN KERJA DAN ERGONOMI LINGKUP UTAMA ERGONOMI Interaksi antara manusia, mesin, dan lingkungan LINGKUP UMUM ERGONOMI Konsumen, pengembangan produk, dsb.

HUMAN, MACHINE, AND ENVIRONMENT 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

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 Work speed and error are generally correlated, considering : age, experience, ability
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.
WHAT IS WORK DESIGN AND ERGONOMICS ? • “The science of matching the job to the worker, and the product to the user”
Worker ? • “The scientific study of human work”
• “Fitting the task/job to the human”
User/customer ?
THANK YOU WORK DESIGN AND ERGONOMICS
