Shopfloor Layout Design Using Blocplan Algorithm To Reduce Waste Transportation Activity On Biofertilizer Products Pt. Centra Biotech Indonesia Klaten Jawa Tengah

Abstract

PT. Centra Biotech Indonesia is a national company that produces and markets environmentally friendly biotechnology products with special microbial base ingredients as the main composition. PT. Centra Biotech Indonesia provides various biotechnology products in agriculture, livestock, fisheries, and so on, to support health and productivity. Currently, Facility layout at PT. Centra Biotech Indonesia has not used specific rules in the placement of equipment and machines used for the production process and does not pay attention to the flow of the production process. This results in limited space for workers, as well as repetition of activities that result in wasted time, inefficient production processes, thereby reducing productivity. The facility layout planning method used in this study is BLOCPLAN. BLOCPLAN is a program developed for facility layout design using a hybrid algorithm that combines a constructive algorithm and a repair algorithm. The objective function of BLOCPLAN is to minimize the distance between facilities or maximize the close relationship between each workstation. Based on the results of data processing, it can be concluded that Waste activities that have a direct impact on the material handling flow are in the Transportation Waste category, namely the distance between workstations. The proposed layout can reduce the distance between workstations by 32% and the distance Traveling Distance of Material Handling by 27%. This indicates that the layout of the proposal can be applied at PT. Centra Biotech Indonesia because it can decrease 32% of Waste of Transportation needed to transfer Material handling and distance for each workstation.
