Abstract
ABSTRAK PT X adalah perusahaan manufaktur yang memproduksi berbagai macam kemasan karton di area Yogyakarta dan Jawa Tengah. Permasalahan yang dihadapi oleh perusahaan adalah kurangnya strategi penyusunan tata letak lantai produksi, dimana stasiun kerja yang memiliki urutan aliran bahan yang berhubungan ditempatkan berjauhan, yaitu pada departemen bahan baku menuju cutting manual sejauh 40 m, departemen bahan baku menuju automatic carton box sejauh 34 m, departemen cutting manual menuju slotting sejauh 31 m, dan departemen penyablonan menuju produk jadi sejauh 22 m. Kondisi tersebut memiliki jarak yang jauh dan dipisahkan oleh departemen lain yang bukan tujuan material handling serta menyebabkan alur produksi mengalami proses backtracking dan bersilang. Oleh karena itu, perlu dilakukan evaluasi lantai produksi dengan melakukan perancangan ulang tata letak fasilitas menggunakan metode algoritma CORELAP, agar dapat meminimalkan jarak material handling. Metode ini menganalisis hubungan kedekatan berdasarkan ARC, kemudian dilakukan pemeringkatan yang dinyatakan dalam TCR untuk memilih departemen sebagai pusat layout. Penempatan departemen lainnya berdasarkan metode western edge dengan acuan nilai TCR. Selanjutnya, didapatkan perbaikan tata letak dan dihitung total jarak material handling untuk membandingkan layout awal dan usulan. Berdasarkan pengolahan data terdapat perbedaan yang signifikan antara layout awal dan layout usulan. Pada layout awal total momen perpindahan material dihitung menggunakan jarak rectilinear menghasilkan Proses A sebesar 689 m/hari, Proses B sebesar 599 m/hari, Proses C sebesar 418 m/hari, dan Proses D sebesar 325 m/hari. Sedangkan layout usulan mengalami penghematan total momen perpindahan material pada Proses A sebesar 318 m/hari, Proses B sebesar 258 m/hari, Proses C sebesar 227 m/hari, dan Proses D sebesar 168 m/hari. Hasil pengolahan data tersebut menunjukkan bahwa dengan menggunakan metode CORELAP dapat memberikan total momen perpindahan yang lebih kecil dimana lebih meminimasi jarak material handling dibandingkan dengan layout awal. Kata kunci: Perancangan Tata Letak Fasilitas, Material Handling, Computerized Relationship Layout Planning, Backtracking. REDESIGN OF PRODUCTION FACILITIES LAYOUT USING CORELAP ALGORITHM TO MINIMIZE MATERIAL HANDLING DISTANCE AT PT X ABSTRACT PT X is a manufacturing company that produces various kinds of cardboard packaging in the Yogyakarta and Central Java areas. The problem faced by the company is the minimum strategy for preparing the production floor layout. Workstations with related material flow sequences are placed far apart, in the raw material department to manual cutting as far as 40 m, the raw material department to automatic carton boxes as far as 34 m, and the manual cutting department is 31 m to slotting. The printing department is 22 m to finished products. These conditions have long distances and are separated by other departments that are not the purpose of material handling, causing the production flow to experience backtracking and crossing processes. Therefore, it is necessary to evaluate the production floor by redesigning the facility layout using the CORELAP algorithm to minimize material handling distances. This method analyzes the proximity relationship based on ARC. Then a ranking is performed, which is stated in the TCR to select the department as the center of the layout. The placement of other departments is based on the Western edge method regarding the TCR value. Furthermore, layout improvements are obtained, and the total material handling distance is calculated to compare the initial layout and the proposal. Based on data processing, there are significant differences between the initial design and the proposed layout. In the initial design, the total moment of material movement is calculated using the rectilinear distance resulting in Process A of 689 m/day, Process B of 599 m/day, Process C of 418 m/day, and Process D of 325 m/day. Meanwhile, the proposed layout saves total material movement moments in Process A of 318 m/day, Process B of 258 m/day, Process C of 227 m/day, and Process D of 168 m/day. The data processing results show that using the CORELAP method can provide a small total moment of displacement which minimizes the material handling distance compared to the initial layout. Keywords: Facility Layout Design, Material Handling, Computerized Relationship Layout Planning, Backtracking.
