Abstract

PT. XYZ merupakan sebuah perusahaan manufaktur yang bergerak dibidang otomotif dan sudah berjalan sebagai supplier komponen otomotif untuk beberapa perusahaan otomotif terkemuka di Indonesia. Kebanyakan proses produksi pada PT. XYZ sudah berjalan dengan baik. Tetapi terdapat salah satu sub produk mereka yang memiliki kendala dalam proses produksinya yaitu muffler K-59J. Pada lintasan produksi muffler K-59J dinilai kurang optimal dalam proses produksinya. Hal tersebut dilihat dari banyak kendala yang timbul selama proses produksi berlangsung. Mulai dari terjadi penumpukan (bottleneck), Target produksi harian sering tidak tercapai sehingga sering terjadi waktu kerja tambahan (overtime), dan jika dilihat secara data nilai efisiensinya hanya sebesar 58,81 %. Dengan demikian, penelitian ini bertujuan untuk meningkatkan performa dari lintasan produksi tersebut. Oleh karena itu diusulkan metode Algoritma Genetik yang bersifat komputerisasi untuk meningkatkan performanya. Proses penyelesaian penelitian ini dilakukan dengan bantuan program matlab dalam pengerjaan metode Algoritma Genetik. Pada prosesnya, dilakukan beberapa tahapan mulai dari membuat representasi genetik, menyeleksi populasi induk, melakukan rekombinasi dan mutasi, dan regenerasi populasi. Tetapi terdapat sedikit perbedaan pada penlitian ini dimana populasi awal yang dibentuk merupakan populasi yang sudah tersaring kedalam syarat-syarat keseimbangan lintasan antara lain sesuai dengan diagram alurnya, dan jumlah waktu stasiun kerja tidak melebihi cycle time. Dari hasil pengerjaan metode Algoritma Genetik tersebut, didapatkan besar efisiensi lintasan sebesar 74,07 % dengan total stasiun kerja sebanyak 18 stasiun kerja. dengan demikian nilai efisiensi lintasan berhasil ditingkatkan sebesar 15,26 %.

Abstract

PT Sarana Energi Investama operates as an industry in the field of electrical components. Some of the products produced by PT Sarana Energi Investama include LVMDP panels, sub-distribution panels, Lighting panel, Emergency panel, Elevator panels, and others. In this case, the layout owned by PT Sarana Energi Investama is still non-standard in nature and was placed without taking into account the flow of production as well as the frequency and relations between production facilities. In this case, research was conducted regarding the design of the facility layout at the workshop facility owned by PT Sarana Energi Investama using the group technology layout. Group technology layout is considered one of the methods that can be used to design layouts in an effective, efficient, and flexible manner for customized product types and is able to overcome production constraints when the quantity of demand fluctuates. In the study, calculations were carried out using routing sheets, calculating the frequency of transfers, determining relationships between facilities, using rank-order clustering algorithms to design group technology layouts, as well as designing intracellular and overall facility layouts. Based on this research, using the proposed layout can increase the efficiency of moving distances by 40.74%, moving time by 31.25%, and material handling costs by 31.25% within a month.
