Micro-scale bag manufacturing businesses often face
challenges regarding the management of manual
production systems, leading to workflow imbalances. This
study focuses on a bag-making MSME in Sukoharjo that
operates on a made-to-order basis with a single-operator
setup. The primary issue is a critical bottleneck at the
pattern-making stage, which consumes up to three hours—
equivalent to 37.5% of the total daily production time for a
single custom bag. This results in a buildup of Work-in-
Process (WIP) inventory and reduced production flow
efficiency. The study aims to identify the production process
flow, pinpoint bottleneck locations, and design simulation-
based improvement scenarios to optimize production
capacity. The methodology integrates Value Stream
Mapping (VSM)—to map material and information flows at
a macro level—with FlexSim software to dynamically and
stochastically simulate manual processing time variability.
The proposed improvement strategy focuses on a low-cost,
high-impact approach through managerial interventions in
workload management (line balancing), avoiding the need
for significant investment in physical assets. The digital
simulation results from FlexSim are expected to provide a
realistic visualization for minimizing work queues,
increasing operator utilization, and maximizing daily
production output in a manner that ensures the operational
sustainability of the MSME.
