Industri manufaktur global terus mengalami transformasi seiring dengan kemajuan teknologi, menggeser paradigma produksi konvensional menuju sistem yang lebih adaptif terhadap kebutuhan pelanggan. Di tengah perubahan ini, industri dituntut untuk merespons tantangan secara cepat dan efisien. Lean Manufacturing dengan prinsip Kaizen menjadi pendekatan strategis, khususnya di industri Low Mix High Volume (LMHV) yang memiliki variasi produk terbatas namun volume produksi besar. Pendekatan ini dinilai efektif untuk meningkatkan efisiensi dan mengurangi pemborosan (waste) di lini produksi. Namun, pengambilan keputusan strategis dalam konteks LMHV bersifat kompleks dan membutuhkan pemahaman mendalam terhadap konsep lean-kaizen tools. Serious Simulation Game (SSG) sebagai media pembelajaran menawarkan pendekatan interaktif untuk menjembatani kesenjangan pemahaman tersebut. Meskipun SSG bukan hal baru, masih sedikit penelitian yang secara spesifik mengeksplorasi penerapannya dalam pengajaran lean-kaizen di lingkungan LMHV. Penelitian ini bertujuan mengembangkan rancangan SSG yang dapat meningkatkan pemahaman peserta terhadap identifikasi waste, strategi penerapan lean-kaizen tools, serta prioritisasi sumber daya.

The global manufacturing industry continues to undergo significant transformation along with technological advancements, shifting the conventional production paradigm towards a more efficient, adaptive and sustainable system. In the midst of these changes, industries are required to adopt methods that are able to respond to challenges quickly and efficiently. Lean Manufacturing with the principle of Kaizen (continuous improvement) emerges as a critical solution in this context, especially for Low Mix High Volume (LMHV) industries that operate with limited product variations but massive production volumes. Lean Manufacturing and Kaizen principles are crucial approaches to improve production efficiency and reduce waste in various manufacturing contexts. Strategic decision-making in managing production efficiency in LMHV is a complex challenge that requires deep understanding. Serious Simulation Game (SSG) as a learning medium is not a new research field, but there are still few studies that focus on teaching lean-kaizen tools concepts in the context of LMHV. Thus, the purpose of this research is to develop a SSG design as a learning medium that can improve understanding of lean-kaizen tools in the LMHV industry, including waste identification, tool implementation strategies, and resource prioritization. The goal of the game is to find the best scenario that results in the highest production efficiency and meets the target demand.
