PT Presa Genta Engineering is a manufacturing company currently handling an order to machine 20,000 water meter coupling products monthly for PT Multi Instrumentasi. A previous design of jigs and fixtures by Mahardika (2023) provided a more optimal solution for the production process of the water meter coupling. However, the design still requires a lengthy setup time, resulting in a long cycle time of approximately 79.89 seconds. This extended setup time has prevented the company from meeting its monthly production targets. This study proposes an alternative automation mechanism for the water meter coupling machining process at PT Presa Genta Engineering. The research methodology includes defining the existing workflow and process, identifying critical processes using a Pareto chart based on the longest and most repetitive operations, outlining supporting requirements, and formulating alternatives for the critical processes. Each alternative is designed using SolidWorks, and process indices are defined for the mechanical movements along the x, y, and z axes. The primary process mechanisms and interactions of each alternative are mapped using Cross-Functional Diagrams (CFD). Programming for each alternative is developed using Ladder Diagrams and verified through Ladder Simulation, ensuring logical continuity. The alternatives are evaluated using the Analytical Hierarchy Process (AHP) tool to identify the best solution based on key criteria such as time efficiency (calculated from the total cycle time), cost (calculated from the total component cost), layout requirements (defined by modification needs), and operator involvement (measured by the number of automated mechanisms in each alternative). This research presents three automation alternatives for the preparation phase of machining the water meter coupling, employing a 2-axis Cartesian robot, automatic screwdrivers, and a vacuum gripper. The AHP evaluation identified the best alternative, which delivers a 54% reduction in setup time, a 4% decrease in production cycle time, and a 7% increase in monthly production output. These results, however, are limited to the conceptual design phase. Further studies are required for PT Presa Genta Engineering to implement these solutions, focusing on real-world layout configurations, mechatronics, fixtures, and machine integration.
