FACILITY LAYOUT REDESIGN USING SYSTEMATIC LAYOUT PLANNING METHOD IN PT. PILAR KEKAR PLASINDO

Good equipment and product design are meaningless if there is no good layout planning. Problems owned by PT. Pilar Kekar Plasindo occurs in the production of small polyethylene. This is because small polyethylene production has large material total transfer distance. Small polyethylene problems include the distance between stations, cross-movement, backtracking, and the broken machine that is still placed in the production section. These conditions make the material handling costs and distance large. Therefore, this research aims to produce a layout design of production facilities that can minimize the distance and cost of material movement. The method used in this study is Systematic Layout Planning (SLP). Three alternative designs were compared, and the second proposed facility layout was chosen because it can reduce the total cost of material transfer by 68.3% and reduce the distance of material transfer by 59.6% from the initial facility layout.

THE EFFECT OF OWNER-MANAGER’S SAFETY LEADERSHIP AND SUPERVISOR’S SAFETY ROLE ON SAFETY PERFORMANCE IN MALAYSIA’S MANUFACTURING SMEs

Safety leadership has been advocated as the most appropriate approach towards injury prevention. Besides, supervisor safety role is also proposed to be crucial towards good safety performance in SMEs. Henceforth, this study aisled to determine the direct impact of safety leadership (safety concern, safety policy, and safety motivation) played by the owner-managers on safety performance within the SME manufacturers in Selangor, Malaysia. Furthermore, this study also evaluated the mediating effect of supervisor safety roles towards safety leadership and safety performance' relationship. The data was collected among 165 SME manufacturing workers from 37 factories and Partial Least Square – Structured Equation Model (PSL-SEM) was performed for data analyses. The results indicated that safety leadership in terms of safety concern, safety policy, and safety motivation has significant impact on safety performance. However, supervisor safety role does not mediate the relationship between safety leadership and safety performance. These results proved importance of direct safety management by the owner-managers and supervisors towards safety performance.Safety leadership approach delivered by the owner-managers could be the best way to improve safety performance despite all the limitation within SMEs.
