# Calculation of Operator Work Efficiency in Textile Industry

**Introduction:**

The operator work efficiency in the process production is needed in the factory or company. Because operator work efficiency greatly affect the output produced by workers. But it also affects the working efficiency of several factors, such as production costs, production time, place of production. Where the higher level of efficiency of an operator, the shorter time required in a production, and the less cost incurred in the process production. Working efficiency greatly benefit the company if the shorter time and lower production costs and output many produced and quality. Calculation of the efficiency of an operator can provide many benefits to the company not only in addition the cost and time but also the resulting product will be quality. For workers working efficiency is also greatly affect the process of their work as they facilitate the work and speed up their work. in the article above has been explained how the calculation of the efficiency of an operator so that it can be applied within the company to produce the level of an operator of high efficiency. But the effectiveness of an operator is also required so that not only efficient but also effective, that can produce optimally. To produce optimal products that may also meet the public demand quickly and accurately.

**Efficiency Calculation Formula:
**Efficiency (%) = [Total minute produced by an operator/Total minute attended by him *100]

Where,

Total minutes produced = Total pieces made by an operator X SAM of the operation [minutes]

Total minutes attended = Total hours worked on the machine X 60 [minutes]

**Example:** An operator was doing an operation of SAM 0.50 minutes. In an 8 hours shift day he produces 400 pieces. So according to the efficiency calculating formula, that operator’s overall efficiency

= (400 x 0.50) / (8 X 60)*100%

= 200/480*100%

= 41.67%

**On-Standard Operator Efficiency:**

Operator efficiency can be expressed in more specific ways, like ‘On-Standard Efficiency’ instead ‘overall efficiency’. An operator may be attending all hours in a shift but if he has not been given on-standard work to do in all hours, he will not be able to produce minutes as per his capability and skill level. In this case, to know operator’s on-standard efficiency following formula is used.

**Operator on-standard efficiency (%)** = Total minute produced /Total on-standard minute attended *100%

Where,

Total minutes produced = Total pieces made by an operator X SAM of the operation [minutes]

Total on-standard minute attended = (Total hours worked – Loss time) x 60 [minutes]

**Example:** An operator was doing an operation of SAM 0.50 minutes. In an 8 hours shift day he produces 400 pieces. Operator was idle ‘waiting for work’ for 30 minutes and his machine broke down for 15 minutes in hours shift. So according to the efficiency calculating formula, that operator’s on-standard efficiency

= (400 x 0.50) / {480 – (30 +15)}*100%

= 200/435*100%

= 45.98%

The above example clarifies that if an operator sits idle during shift hours his overall efficiency will go down.
