Penentuan Alokasi Buffer Untuk Meningkatkan Performansi Lini Produksi (Studi Kasus di PT. General Electric Lighting Indonesia)
Abstract: PT. GE Lighting
Indonesia is a manufacturing company that producing lamp. In generally, PT. GE
Lighting Indonesia’s producing line consists of 5 machines with buffer
allocation storage between machine that have early capacity of buffer1= 1225
units, buffer2= 915 units, buffer3=820 units, and buffer4=545 units. The
allocation of these buffer is definetely done with purpose to place output from
machine before processed to the next machine. Time difference process in every
machine make the stream of production process become less fluent and affecting
less maximal throughput. Other cause that making the throughput of production
line process less maximal is machine damage factor. Although the preventive
maintenance policy is applied in PT. GE Lighting Indonesia remain to be the
machine damage cannot be obviated at production process take place. This
research will try to redetermine the buffer allocation in PT. GE Lighting
Indonesia in order to make the production process more fluent, so that can
increase the throughput in production line. The method that is use to
redetermine the buffer allocation is simulation approach. The reason why the
author use this method is because there wasn’t found a representative and valid
analytical model that match with the system.The simulation is done with
Promodel 4.0 software. Based on the experiment design and running of
simulation, it’s achieved a conclusion that the best alternative buffer
capacity is at 900 units (buffer1, buffer2, buffer3, buffer4 has a same
capacity at 900 units) with average throughput at 9.651 units/shift. While in
the early buffer capacity only produce as many as 9.207 units/shift. Finally,
if it’s compared with the early condition, redetermining the buffer allocation
can increase the throughput of production line process equal to 444
units/shift.
