Abstract

"Sayu Rasa" Crackers MSME faces productivity constraints due to suboptimal production facility layout, resulting in long material handling distances and inefficient production time. This study aims to optimize the production layout to minimize material handling distance and improve production process efficiency. The method used is Systematic Layout Planning (SLP) through stages of material flow analysis, from-to chart creation, activity relationship diagram design, layout alternative development, and evaluation using weighted factor analysis. Implementation results show a 39.1% reduction in material handling distance (from 128 meters to 78 meters per production cycle) and a 20% productivity increase (from 50 kg/day to 60 kg/day). Production time decreased by 15.5% from 420 minutes to 355 minutes for the same production capacity. The research conclusion proves that the application of industrial engineering principles through SLP method effectively improves MSME operational performance with minimal investment.

Abstract

PT. Asthamukti Airtech Nusatama, a cooling system component manufacturing company in Central Jakarta, faced operational efficiency constraints due to high waste in the production process. This community service activity aims to apply Lean Manufacturing principles to identify and reduce waste, particularly waiting, motion, and inventory. The methods used include Value Stream Mapping (VSM), 5S implementation, Standardized Work (SW) development, and Kanban system application through an Action Research approach over 5 months (April-August 2026). Implementation results showed a 20% increase in Overall Equipment Effectiveness (OEE) from 65% to 78%, a 30% reduction in lead time from 5 days to 3.5 days, a 40% decrease in work in process (WIP) from 450 units to 270 units, and a reduction in rework from 8% to 3%. This activity proves that the application of Lean Manufacturing effectively improves operational efficiency in medium-scale manufacturing companies with minimal investment and a participatory approach involving all elements of the organization.
