Abstract :
Flights at Ahmad Yani International Airport, Semarang, which are
crowded, require Handling field workers to be more competent in carrying out their
work. Conditions in the ground handling operation Kokapura run a shift work
pattern with a comparable number of workers between the morning and afternoon
shifts. Different flight schedules make the number of workers' needs unbalanced.
Therefore, it is necessary to calculate the number of workers needed for ground
handling operations in Kokapura in accordance with the conditions of the flight
schedule.
Calculation of workload in the form of mental work using the NASA-TLX
method. The NASA-TLX method uses 6 indicator dimensions to measure the
workload. The six indicators are mental demand, physical demand, temporal
demand, performance, frustration level, and effort. All of these indicators have a
scale from the lowest of 0 to the highest of 100. Based on the collection of
questionnaires given to Kokapura ground handling operations workers. And also
to find out at what time the most workers needed.
The results of the workload calculation show values with high and very high
workload categories. The level of mental workload of Operation Kokapura
employees, there are 3 positions in the very high category and 4 positions in the
high category. The more the number of flights, the number of workers will increase,
the more diverse types of skills needed, the number of workers will also increase.
For normal conditions, the total number of workers needed is at most 14.00-15.00
WIB, which is 39 workers and at 19.00-20.00 WIB, which is 39 workers.
