Abstract:
This research aims to analyze the effectiveness and efficiency value of plywood
production machines. This research was conducted by observing and recording the production flow
or workflow of the machines in a series on the plywood production process used in PT Surya Satrya
Timur. Data retrieval is only taken on the morning shift which is from 07.00 to 17.00 WITA and on
each machine is observed three times. Based on the data obtained for log cutting machine,
effectiveness (90%) and efficiency (41.70%). Rotary machine, effectiveness (90%) and efficiency
(81.56%). Machine Continues Dryer, effectiveness (90%) and efficiency (85.19%). Core jointer
machine, effectiveness (90%) and efficiency (76.1%). Glue spreader machine, effectiveness (90%)
and efficiency (59.43%). Cold press machine, effectiveness (90%) and efficiency (30.03%). Hot press
machine, effectiveness (90%) and efficiency (79.27%). Sizer machine, effectiveness (83.34%) and
efficiency (37.41%). Sander machine, effectiveness (90%) and efficiency (54.15%). Thus, the
effectiveness value of the use of machines in one series at PT Surya Satrya Timur has achieved a
high effectiveness value of 90% on eight machines in the phase of the plywood production process
including Log cutting, Rotary, Continues Dryer, Core Jointer, Glue Spreader, Cold Press, Hot press
and Sander and one machine the value is not yet high i.e. at the stage Sizer only reached 83.34%.
While the efficiency value of the machine at PT Surya Satrya Timur ranges from 30.03% - 85.19%.
The most efficient stage in the production process is the Continues Dryer stage of 85.19% and the
lowest efficiency is at the Cold Press, Sizer and Log Cutting stages of 30.03%, 37.41 and 41.70%
respectively
