Abstract

Sintering Plant at PT. Krakatau Steel (Persero) Tbk apply a shift work system which is divided into three shifts. The difference in work shifts will result in differences in the operator-s physical and mental workload. Through data processing of body mass index (BMI), energy consumption and % CVL, it is known that there are 16 operators with normal BMI, consisting of 7 operators who have a light physical workload (<30%), 5 operators that experience moderate physical workload (30% -60% ) and 4 operators experience a rather heavy workload (60% -80%). Through processing with the NASA-TLX method, it can be seen that the mental workload score on 16 operators is in the range 52-92. So that the results show that operators in shift 1 have an average physical workload higher than shift operators 2 and 3. While operators in shift 3 have an average mental workload score higher than shift operators 1 and 2.
