Usulan Perancangan Ulang Tata Letak Lantai Produksi Pembuatan Screen (Penyaring) Minyak & Gas dengan Menggunakan Metode Grafik dan Craft pada PT. Pipa Mas Putih

Abstract

Production floor layout is the arrangement or planning of space within a factory or production facility that regulates the position of machinery, equipment, work areas, and material movement paths. Pipa Mas Putih company is a manufacturing company that produces screens for the oil and gas industry. This company has a common problem, namely the non-achievement of production targets due to the inefficient flow of materials on the production floor layout. This is caused by cross movement, backtracking, and the large distance between stations. So that the distance of material movement, the frequency of movement, and the total moment of movement are quite large. This problem can be solved by making improvements to the production floor layout using the graph method and the Computerised Relative Allocation of Facilities Technique (CRAFT) algorithm. This research aims to design a production floor layout that can minimise the distance of material movement, the total moment of movement, and increase the line efficiency rate value above 75%. After redesigning the layout, the proposed layout of the graph method was obtained as many as 2 alternatives and the CRAFT algorithm as many as 2 alternatives. Based on the results of the research, the selected proposed layout is alternative graph method 2. The results of the research with alternative graph method 2 are a decrease in the value of material displacement distance and total displacement moment from 607.4 metres to 331.04 metres for material displacement distance and 31,502.9 m / month to 16,494.4 m / month for total displacement moment, as well as an increase in line efficiency rate value from 58.92% to 92.29%.
