Penerapan Metode Fuzzy Analytical Hierarchy Process dan SLP dalam Rangka Perancangan Ulang Tataletak Fasilitas Produksi Bata Ringan di Pt. PQR:

Application of Fuzzy Analytical Hierarchy Process and SLP Methods in Order to Redesign the Layout of Light Brick Production Facilities in PT. PQR

Abstract

PT. PQR merupakan perusahaan yang bergerak dalam produksi bata ringan. Bata ringan diproduksi menggunakan sistem Autoclaved Aerated Concrete (AAC). Dari hasil pengamatan di perusahaan, produk bata ringan sering mengalami kerusakaan karena jatuh dari pallet saat dipindahkan menggunakan hand lift. Hal ini disebabkan oleh jauhnya jarak perpindahan antara lantai produksi dan gudang produk, sehingga operator kesulitan dalam proses pemindahan. Tujuan dari penelitian ini adalah untuk merancang ulang tata letak fasilitas dengan menggunakan pendekatan metode Fuzzy Analytical Hierarchy Process (Fuzzy AHP) disertai dengan metode Systematic Layout Planning (SLP) untuk mendapatkan rancangan yang efisien. Hasil pembobotan matriks berpasangan menunjukkan tenaga kerja adalah variabel yang memiliki bobot kriteria tertinggi sebesar 0,2735. Setelah dilakukan analisis didapatkan bahwa kedekatan antar departemen sangat dipengaruhi oleh perpindahan tenaga kerja (operator) antar departemen. Dari hasil analisis, dirancang activity relationship chart (ARC) untuk mendapatkan kedekatan antar departemen, kemudian dirancang layout baru berdasarkan pertimbangan luas masing-masing departemen. Hasil rancangan ini dibandingkan dengan rancangan awal, sehingga diperoleh pengurangan jarak sebesar 165,01 m.

PT. PQR is a company engaged in the production of lightweight bricks. Lightweight bricks are produced by using the Autoclaved Aerated Concrete (AAC) system. From the observations in the company obtained results thatight brick products often experience damage due to falling from the pallet when moved using a hand lift. This is due to the distance between the production floor and the product warehouse, so operators have difficulty in the process of moving. The purpose of this study was to redesign the layout of the facility using the Fuzzy Analytical Hierarchy Process (Fuzzy AHP) with the Systematic Layout Planning (SLP) method to obtain an efficient design. The paired matrix weighting results showed that labor is a variable that has the highest weight of 0.2735. After an analysis was conducted, it was found that the closeness between departments was strongly influenced by the movement of labor (operator) between departments. The results of analysis, a relationship chart (ARC) activity was designed to get closeness between departments, then a new layout was designed based on the broad consideration of each department. Furthermore, the results of this design were compared with the initial design, such that obtained a distance reduction of 165.01m .
